What's new in botany?

My colleagues have been very busy, and the things you can learn from them.

Horsetails may have been a favored food of sauropods, and cycads the least favorite.
Water clover ferns have been around unchanged for over 100 million years.
Somebody else got did a similar experiment to one of mine and got the same results!
One colleague began his talk with a summary and conclusions because of his penchant for going too far too fast and covering too much. There was applause.
Our scientific discipline has some really bright young people.
The newest molecular techniques are completely unknown to me, even the name was new.
At least two chapters in a book I'm writing have to be revised. Blast.
Evolutionary relationships among seed plants remain uncertain.
Hornworts are now considered the sister group to the rest of land plants, which are mostly vascular plants. Liverworts are now even more certainly the oldest lineage of land plants.
Termites were eating wood more than 100 million years ago.

OK, you get the flavor. Some of these and others deserve elaboration, so explanations will be forthcoming. What sounds most interesting?
