Plant of the week - Wild cacao

Cacao is our source of cocoa, chocolate. It's scientific name is Theobroma, drink of the gods, so called because a hot, fatty, spicy, bitter chocolate concoction was the royal beverage of the Aztecs. This may not sound good, but chocolate contains a chemical similar to caffeine, so strong chocolate is a stimulant. A local chocolate shop makes a deeply rich, semi-sweet, dark chocolate bark with ground up coffee beans in it. Just a couple of pieces can give you a buzz; it's should be illegal to sell to minors.

This rain forest tree is native to Costa Rica, and like many tropical trees its flowers appear directly out of its trunk and branches. One of the flowers is shown here and it's a little hard to figure out. It seems to have more perianth parts than usual flowers. From the top down, there are bracts, sepals with a curved, translucent base and a small heart-shaped red apex folded back upon itself, and lastly red petals. The stamens are hidden within the base of the sepals.

The fruits that later develop are rather hard, grooved, pink capsules within which a soft pulp surrounds hard seeds from which the chocolate is obtained. Such fruits are mammal dispersed. The soft pulp provides a nutritive reward and the hard seeds are discarded, or if swallowed, pass through the GI tract unharmed, and perhaps prepared for germination.

This particular species (T. siminaca) is wild and not the cacao tree of commerce (T. cacao).

A rotten apple in every faculty?

My colleagues and I just met to consider the tenure and promotion of a junior member of our faculty. She presented a well-balanced and well-documented package of accomplishments that made this one of the easiest decisions we have encountered in recent years. With virtually no discussion we voted umpteen to 1 in favor of her tenure and promotion by a secret ballot. Yes, that was umpteen to 1. One no vote. One person thinks an outstanding junior member of our department should be dismissed. Oh, they knew the vote would be overwhelming positive so this was nothing but a personal statement.

Does every faculty have to contain at least one jerk who gets their jollies out of being an a$$? Could there be any more cowardly act than to hide behind a secret vote? What sort of inadequacies prompt such actions? And what do they think it accomplishes? What did their protest vote really mean since no one has any idea whatever it is?

Well, it let us know that there is at least one person among us that you would not and should not trust with confidential information. It lets you know that at least one of us is in not fully rationale and socially mature enough to be treated as an adult. It lets you know that someone is being eaten away by an ethical and intellectual rot that cannot help but damage themselves, a skulking, nasty, venomous sort of rot that leaves your core black, a real rotten apple. And you have to watch and make certain that such apples don't spread their rot to any others. Unfortunately you just don't know which one.

This demonstrates the down side of secret ballots; it lets cowards hide. Someone without any guts dislikes our junior colleague, and maybe the whole department, and they wanted to send a message. Quite a few years ago, a now retired colleague routinely voted against virtually all tenure and promotion decisions, but at least he had the decency to say, "They don't measure up to my impossibly high, arbitrary standards." Of course setting the bar so high no one can clear it, including himself, and withholding his approval of anyone who was not a member of the national academy of science, demonstrates a certain tenuous hold on reality. But at least you knew his reason.

The actual list of potential bad apples is not as long or as extensive as one might expect. You see after my afore mentioned colleague retired this sort of thing stopped happening. In the interim we have tenured and promoted only a few people, and now a bad apple appears. I've worked with some of my colleagues over 30 years, and while all are not necessarily charming, I know of what stuff they are made. None of us liked the way many senior faculty used, abused, the tenure process to bully junior faculty. We changed the department's climate, but apparently one of my newer colleagues did not learn that lesson. How very unfortunate! It hurts to know the department made at least one mistake in deciding tenure. And without doubt such people never get better, they only get worse as the perceived slights and injuries mount up and the rot continues to grow.

I shall tell my young, newly tenured colleague to use the freedom of tenure well because it comes with responsibilities too. One of which is that you deal with your colleagues honestly and forthrightly.

Plant of the week (eon?) - Cooksonia

This picture of Cooksonia is pretty remarkable. Not so much for displaying this plant's simple beauty, not even because the picture is actually in focus, but because this plant has been extinct since the Devonian some 380 million years ago.

This fossil is looking particularly good because it is a model on display in the Darwin House at the Royal Botanical Garden at Kew.

Cooksonia is significant because this is the first land plant sporophyte to show apical branching. As the axes grew, the apex divides into two equal axes, a type of branching called dichotomous. Fossils show axes of Cooksonia branching thusly 1 to 4 times. Each axis then terminating with a sporangium. This appears to be a way of getting the maximum number of dispersable offspring from a single fertilization event.

Cooksonia is also significant because at the time this was the tallest plant of its day. These axes towered some 5 centimeters (nearly 2 inches) above the substrate. It is also the earliest appearing plant to have vascular tissue, xylem, although the oldest specimens found in Silurian sediments may not have possessed true xylem.

This plant is the first step on the way to trees, and it did not really take too long for the first trees and forests to appear (near the end of the Devonian).

Will I get a new "commander-in-chief"?

A neighbor cheerfully greeted me outside our polling place this beautiful fall morning, "Well, no matter what tomorrow you'll have a new commander-in-chief". Actually I think they said "commander and chief", but that's not the issue. Tomorrow I'll have a president-elect. In fact unless you are in the military, you do not have a commander-in-chief, you have a president.

Actually too much is made of this constitutional definition, although the buck has to stop somewhere. If the president was not also the commander-in-chief, then the military would only answer to its own commanders, who would be free to act outside of any civilian rule. So the highest elected official has to have that authority.

Many of my fellow citizens argue that only a person with military experience should be in such a position, but I think it may be a good idea to let the military try explaining their reasons for military actions, and what might go wrong, to someone who doesn't necessarily think like them. Guns, bombs, and military might just don't solve all problems. And the big problem the military has is that it is a closed fraternity; they only talk and trust each other. They don't have enough civilian friends or confidants.

It reminds me of visiting the Naval War College many years ago while still in my long-haired days. I have never been looked at with so much disdain and disgust ever before or since. And why? Well, I wasn't one of them, clearly, so I wasn't to be trusted, or liked, or anything. I was some inferior who probably thought the war in Vietnam wasn't a very good idea (true enough!). So making the military explain itself to a civilian leader is a great example of balancing power.

Too much is made of the commander-in-chief's authority. We don't have to do a damned thing the president says unless it becomes a rule of law. Indeed, only congress can declare war, and since they haven't the USA is not fighting a war in Iraq or Afganistan. It's only a military action. And by definition you can't have a war on terrorism. And that probably should tell the president something important; you're trying to fight terroism the wrong way. You fight other states with a military.
The problem is rather simple; war is declared against another state, and usually follows a long list of "where as" statements that resulted in this state of affairs. But neither Iraq or Afganistan has done anything to the USA.
Thus I have a considerable dislike of the "hail to the chief" promp and circumstance march because it is purely militaristic. Sorry, I don't have to salute (although we once had a provost who thought we did). So let's call the winner what they are, the president-elect. Maybe we could put new words to the Family Stone song, "We are president". No, that doesn't work, too royal sounding.
Any other suggestions?

Plant of the week - October 21, 2008

Azure beauty berry
Callicarpa dichotoma (Verbena family).

Generally when it comes of fall color you think of plants whose leaves turn a nice bright color. But the beauty berry has the neatest electric blue display of fruits in September and October. This particular one holds a cluster of fruits above each leaf axil on a gracefully arched branch. What could be nicer. This particular fruit color, bright blue, is pretty rare among temperate zone plants, but more common in tropical
forests. This Chinese species has more cold hardiness than American beauty berry.

Small light purple flowers preceed the fruit, and while nice enough, are no match for the fruit display. Flowering and fruiting are on new wood, so the bush is cut back to 12-18" every spring, or you let the bunny rabbits do it for you over the winter. This low shrub grows fine in light to medium heavy shade. You might consider placing it where it could be viewed from above, so next to walkways or below windows.

Now that frugivorous birds are migrating through, the berries are beginning to disappear, so the display definitely attracts some species. This is one of the nearly 150 species growing in my personal arboretum.

Does botanical research offend the dignity of plants?

The Swiss ethics committee has declared that plant scientists are not allowed to do research that offends the dignity of plants. This initially struck me as hard to believe because I think of the Swiss as a pretty level-headed and practical people, but this is just goofy.

Maybe this was just a Swiss attempt at humor. But this is for real and my botanical colleagues must deal with this. Now I do think certain plants have a majesty, and they certainly can be violated, for example, by cutting down redwood trees to make somebody a porch deck. But is the dignity of a cabbage offended when it is converted into coleslaw? Does it regain any of its dignity when converted into sauerkraut? Are my prairie plants dignified? Does a fertilizer treatment offend them?

You really have to wonder about what kind of cuckoos are on the Swiss ethics committee because they are guilty of pure anthropomorphic thinking. Unfortunately until some level heads prevail, my botanical colleagues in Switzerland are stuck dealing with this.

What this is all about is a resistance to genetically modified crops. And we must presume that altering a plant’s genetics is an affront to its dignity. I guess a certain case can be made for that. Let’s face it, a toy poodle doesn’t have too much dignity. But humans have been altering the genetics of plants ever since their domestication began. Wonder if ethicists like seedless grapes? Have they ever had a fertile banana? Eating around all those big, hard seeds is something special. What could be a bigger offense to the biological dignity of an organism than to propagate sterile plants when their whole purpose was to reproduce?


So who will decide what offends the dignity of plants? To help out the Phytophactor will channel your research plants to determine if their dignity is offended, for a modest fee, payable in Swiss cheeses, of course.

An academic tragedy

A young former colleague of mine was found dead in his apartment a couple of weeks ago. I just found out because his apartment is a couple of thousand miles from Lincolnland in California. It's been at least a decade since he left our institution, and I know what resulted in his dismissal. I rarely saw him in recent years, and I cannot say how he was getting along in life lately. But my guess is that the villain in this tragedy is addiction to that most common and socially acceptable substance, ethanol.

It kept a bright young fellow from having a successful academic career. I cost him his drivers license and for awhile his freedom. It cost him his only tenure track academic position. It cost my profession a promising young botanist, and you have to love someone who was just cuckoo for floral polymorphisms. And now it has cost him his life.

Jeff was not yet highly accomplished as his career was just starting, but everyone who had ever worked with him was impressed by his intellect. And biologists are a pretty capable bunch of people, so it takes a really bright and creative person to impress so many. And he was a likable enough fellow. Our faculty were extremely pleased when we hired him; he seemed like a good addition. The tragedy is that Jeff could have accomplished so much but for this fatal flaw.

This serves as yet another reminder that us average fellows, whose academic success is the result of just keeping at it, have a lot to be thankful for, but still Jeff's death saddens me greatly. Bright candles burn way too quickly.

Nifty plant of the week - October 3, 2008

Too much blogging about academic life and politics was getting me down. Plants are much more fun and interesting. So to improve my outlook the Phytophactor will introduce a new plant at least once a week.

Kalanchoe - (Stone crop family) "mother of thousands"

Some disagreement exists about the pronunciation and several opinions have been offered: kal-an-COH-ee, ka-LANK-oh, ka-LAN-coh, kal-an-COH-ee, kal-an-CHOH. I was taught the 4th one, but cannot say which is most correct.

The plant bears pairs of thick, fleshy leaves that have either a waxy or fuzzy covering of hairs. Both limit water loss and this genus is native to semi-arid regions of Africa. Ornamental species are widely grown, and their tolerance of dry conditions makes them good house plants.

Several species bear plantlets along the toothed margins of their leaves. Once the plantlets develop a couple of pairs of little leaves and some roots, they easily detach and quite readily begin independent growth.




Mature plants are soon surrounded by hundreds of clonal offspring giving rise to the common name "mother of thousands".




Although usually raised for the appearance of their leaves, many species have rather attractive 4-parted bell-like flowers with pink to red petals.


















Mavericks are not good leaders

I generally avoid being political, but something occurred to me and it struck me as important enough to share.

John McCain touts his status as a maverick as one of his primary qualifications for being president. Well, it occurred to me that I know a great deal about being a maverick because I have had a long career as a maverick among our faculty.

I’m very good at seeing issues from other perspectives and I often have a different view than the majority of my colleagues or the administrative main stream. At times I can broker cooperation by finding common ground, but that’s the best thing a maverick can do, other than being more or less independent of big cliques. Often I can get to the heart of an argument or issue because I don’t care all that much one way or the other, and in this instance provide a means of moving forward. So I’m an independent thinker, and that’s good, but mavericks are often a loose cannon on the deck; you are never sure which way they will shoot as the ship rolls to and fro.

Here’s something else I know about myself. I’m not a good leader; I lack those intangible qualities that make for leadership. And this is John McCain’s problem. He isn’t a good leader either. Nothing in his long and storied career suggests he is a leader. In fact being a maverick almost assures that you are not a leader because leaders behave in a very different way. Consider McCain’s military experience as a fighter pilot. These guys aren’t leaders, they’re mavericks (with apologies to the Senator for the necessarily comparing him to a 2nd rate actor). He picked Sarah Palin because she too has some credentials as a maverick, but nothing in her record of administrative experience suggests she has the qualities of a natural born leader either.

And leadership is something that no one seems to talk about amidst all the bickering and sniping that substitutes for political discourse these days. The McCain-Palin ticket offers nothing in terms of leadership. Neither candidate has the bearing, the attitude, the stature, the it’s-hard-to-describe-what-it-is but you-know-it-when-you-see-it quality. They feign the fictional macho leadership as it is so often parodied on TV and in movies. Both McCain and Palin have been emphasizing their tough decisiveness as if that were the end all and be all of leadership.

A real leader surrounds themselves with competent people, then demands and gets the best performance from everyone. For that you need three qualities: restraint, generosity, and empathy, which are a lot less macho stuff. Both McCain and Palin clearly lack restraint. They portray themselves as people of action, yet good leaders have the restraint to avoid snap decisions or undue action until the true nature of the situation is clear. This also takes an intellectual approach as opposed to the unthinking certainty of ideological thought that has been the hallmark of the current occupant. And of course a true leader does not work to obfuscate the situation for political ends either. To work with other people you have to have empathy for their position, to deeply understand their position, and so far this ticket has not gotten beyond campaign rhetoric. None of this suggests any empathy or understanding for others, and indeed, both seem quite proud of intractable, absolutist positions. Good leaders must be generous in their using their time, their treatment, and their recognition of others to accomplish their goals. Mavericks like doing things on their own, and sometimes have a hard time recognizing, listening to, and making use of the contributions of others.

In fact if McCain were a natural born leader, it would not have taken him so many years to have acquired his party’s nomination. His natural leadership talents would have been recognized long ago. So whether you agree with his positions on issues or not is almost a moot point, McCain will make a lousy leader of this country to say nothing of the free world. He’ll be a poor leader for different reasons than why the current occupant is a poor leader, but that doesn’t matter. This is why foreign leaders who certainly know McCain have not endorsed his candidacy or expressed any support; they recognize that he lacks the qualities of leadership.

Our country has been floundering for some time now on basic issues of freedom, democracy, and good citizenship, and what we as a country should stand for, and it’s because the current occupant is such a poor leader. He simply lacks the smarts and ability to communicate to be a leader. In fact his lack of leadership ability, and his departure from his own best instincts, turned him into a follower of Darth Cheney rather than a leader of the free world. And no one is better off because of it. We need leadership and it isn't going to be found on this ticket.

New Provost charging forward into the past.

Yes folks, our great institution of higher learning located here in the maize and soybean desert of Lincoln land has hired itself a new provost. Well, actually no provost is actually new, virtually all are used, administrators who occupied slightly subordinate positions at bigger institutions, or who occupied the same position at a smaller institution, both looking to move up, but in different ways. Each promises to bring new and better ideas, modes of operation, and innovative practices to your institution, retreads of ideas somebody else had at their former institutions. And for some strange genetic reason, these administrators are compelled by the Peter Principle to seek ever higher positions until their true level of incompetence is reached. So I welcome our new provost with no great enthusiasm, which is not personal at all, but a general cynicism born of experience.

Provost Plodder has introduced a “new” policy that will return us to the teacher’s college mentality we have for so long attempted to out grow. Faculty positions are one of the largest resources the provost has to dole out. Provost Plodder has announced that staffing decisions will be based upon number of majors, credit hour generation, student demand, and job demand in Lincoln land. Wow, such innovation really takes your breath away. Of course bean counting in Lincoln land is common enough, but usually it’s done in bushels.

This means Provost Plodder takes our primary charge as a state-supported institution seriously. Our venerable institution is supposed to train workers for the employers of Lincoln land. Yes, that’s right, train, not educate. Sit. Roll over. Fetch. And just for Lincoln land too; it’s no good providing an education to a tax paying citizen if they move to Iowa or Ohio. Next the 60% of our alumni who live out of state will probably be asked to retroactively pay out of state tuition. And it’s our fault entirely because we educated them and instead of training them. Maybe I didn’t mention the Provost’s first name, Parochial.

Yes, folks Provost Parochial Plodder made no mention of scholarship, makes no exceptions for departments with graduate programs versus those without, and takes no qualitative aspects into account. Why what if some bright, creative student, a native of Lincoln land, wants to study botany? Well, those students who have an interest in low enrollment, low demand, no jobs in Lincoln land programs are just crap out of luck. And besides they should seek job training, not an education. There’s always a demand for de-tasselers and bean walkers, if properly trained.

Years ago the state of Ohio applied Provost PP’s system to state liquor stores after they found out that 20% of their stock made up 85% of their sales. Bud Light and Seagram’s 7 drinkers didn’t even notice the change. PPP will bolster those programs that currently have the most people, fill the most seats, are most popular, those pandering purveyors of the ordinary, and of course, that’s only what's popular in Lincoln land. If you like something a bit unpopular like maybe philosophy or religion, or a nice chianti with faba beans, well, too bad. And you might even wonder how your kids would grow up if you let them decide what to eat the way our provost decides what to support. Letting student preferences determine academic programming makes just as much sense.

Now I do not argue that numbers are unimportant, but scholarly programs that engage students in scholarship and do so with the aid of graduate programs are without question quality programs where students can become so educated that they can seek careers anywhere. Such programs are high quality, but they are not going to be the biggest producers of credit hours or the most popular. Provost PP’s policy ends up robbing peter to pay paul, removing quality to bolster quantity. And this is why the bad old days may return. It reminds me of President Doofus all those years ago when I was hired. “We’re a teachers college so you should teach, and teachers are in demand. It’s that simple.” And so was he. Our institution was the K-mart of education under his guidance. And guess which college had a flashing blue light on top?

The faculty finally got tired of this go nowhere, do nothing administration, and we responded to his state of the university address in detail, in full harmony. And to our amazement he resigned. Dang! If we knew he'd fold like a cheap suitcase, we'd have gone after him sooner. But in recent years our institution has voiced a new image, one quite antithetic to Provost Plodder’s policy. Quality does count, and not just in teaching.

Provost Plodder is threatening 15 years of academic progress by demoting the most important decisions a university can make to an exercise in bean counting. Oh, did I mention PPP’s academic background was in education? Did I have to? Where else do such innovations come from? So these will not be happy days for programs that have labored to provide our institution with something of a scholarly reputation, quality academic programs, and highly qualified students. Now we’ll be staffing those high volume, popular, we-can-train-you-for-a-job programs, and our university will be little more than a glorified community college. Maybe we can install a drive-up window. But the best and brightest students of Lincoln land would do well to consider universities in neighboring states, unless they too have recently hired a provost from Kneebitska. The next state is not too far to drive for a really good education or bottle of wine. You won’t be getting one around here.
