Not too many people notice these little pink flowers on a little shrub in our glasshouse. Most people think it's some kind of miniature holly because of its leathery leaves with spiny margins, and that's what Malpighia coccigera is called some times. This species is a close relative of the Barbados cherry (M. glabra). The fruit of both species is a bright red berry/drupe, but the former's fruit is pretty small. It's sort of unusual to see petals on stalks, but the sepals peeking through each have a pair of glands. Sometimes this shrub is grown as an ornamental, and for many years TPP had one as a bonsai tree that required constant pruning (a total pain because it's a stubborn plant). Nonetheless it's charming in flower especially when seen close up. The name is interesting because it's an honorific for Marcello Malpighi, a professor at Bologna during in mid1600s. Here's his Wikipedia entry: Malpighi gave his name to several physiological features related to the biological excretory system such as the Malpighian corpuscles and Malpighian pyramids of the kidneys and the Malpighian tubules of insects. Well, that is just an outrage! Marcello was one of the father's of plant anatomy, and not a mention of that or the plant genus named after him! This is the usual human-biomedical bias about what's important in biology! What would you rather have named after you? Some part of the excretory system or a really attractive flower?
Wow, almost missed the fact that today is a Friday, and that just wouldn't do, would it? Here's another denizen of our glasshouse, one of the most prolifically flowering shrubs in the collection: Galphimia glauca. This is another member of the Malpighia (Barbados cherry) family; you may recall the miniature holly of about a month ago. One of the factoids presented then was that Malpighia was an honorific taxonomic name; so is Galphimia but in a very unusual way. See if you can figure it out before reading any further. Any puzzle loving people out there get it? Galphimia is an anagram of Malpighia so maybe it's a fonichori. This genus also displays the "stalked petals" common in the family. This shrub has some limited ornamental value in warmer climates and is a popular non-component of homeophathic remedies for hayfever, but that's good because the leaves and twigs are poisonous and extracts used as an insecticide. The flowers are about 1.2-2 cm in diameter.
A favorite small shrub in our glasshouse is this week's Friday fabulous flower, commonly called "miniature holly" (Malpighia coccigera) because of the glossy, spiny margined leaves. Like many members of this family (Malpighiaceae) the flowers have spoon-shaped petals, here ruffled and fringed to boot, and while not large they are produced in great numbers making for a very attractive display. This species, native to the West Indies, is used as a tropical ornamental. The fruit is a red berry and edible, as are several larger species whose fruit are better known as Barbados cherries or acerolas. The flowers have a funny fragrance, not altogether pleasant. In between the upper three petals glandular sepals can be seen that secrete an oily substance as a reward for the bee pollinators. The genus is an honorific for Marcello Malpighi (1628-1674), professor and naturalist at Bologna. He was an early anatomist making contributions to both botany and zoology (malpighian tubules).
