The Official Blog of the Institute of Botanical Training. Monday, February 13, 2012. Like many eager Sasquatch documentarians before me, I feel compelled to share a video of an organism whose existence is denied by the scientific community. If you know Dichanthelium linearifolium, this creature should look different to you for reasons I point out in the video. Fernald, M.L. 1934. Realignments in the Genus Panicum. Rhodora 36(#423).

The Vasculum: January 2012

The Official Blog of the Institute of Botanical Training. Sunday, January 29, 2012. Tragia ramosa: the spicy side of tactility. Great Oden’s Raven! This is what I exclaim moments before I locate Tragia ramosa. 8217;s maniacal “gotcha” game time and time again. That being said, I am a big fan. It just has that lovable bulldoggish quality to it. And the fruits, how amazing are those bristly gynophorous brutes? The complexity of Tragia. Is covered with hundreds of thousands of such trigger happy hairs.

Every winter, as the cold grip of dormancy overtakes our vascular flora, my attention is turned from phanerogams to cryptogams: bryophytes to be specific. Here is a closer look. On soil o...

The Official Blog of the Institute of Botanical Training. Monday, June 28, 2010. The Dichanthelium Series: Dichanthelium praecocius. There, beneath the big grasses of the prairie, nestled next to triple-canoed violet fruits, aborted Scleria. Achenes and the tumbled tops of Agrostis hyemalis. Is a grass that no one sees. It is hairy and dirty. The stems emerge tangential, node, soon bend geniculate but not quite erect. Hairs are ubiquitous but sparse enough to collect dirt; char in good years. He can feel...

The Official Blog of the Institute of Botanical Training. Sunday, April 8, 2012. I have become increasingly aware and concerned about what appears to be a distinct species that is largely ignored/lumped in recent literature and completely unknown to most botanists. Several years ago when I first started working in wetland communities I was introduced to Scirpus cyperinus. And its fitting misnomer “wool grass” (why not “wool sedge”? Here they are side by side:. Or at least S. cyperinus. And that’s it.

The Official Blog of the Institute of Botanical Training. Thursday, February 19, 2015. The Elymus of Imagination. You know how in the movie, based on the Stephen King book, "Christine" the nerd slash soon-to-be vigilante hears the car he loves telling him that it can repair itself after the jocks trashed it and pooped on the dashboard? How he says "okay. show me." and then the headlights come on with eerily piercing music? I feel like that when I find an Elymus. Here is a close-up of the Elymus virginicus.

The Vasculum: August 2010
http://thevasculum.blogspot.com/2010_08_01_archive.html
The Official Blog of the Institute of Botanical Training. Wednesday, August 4, 2010. It was just about a year ago when I first heard of Carex aureolensis. While walking with a fellow botanist he asked if I had noticed it in the Cyperaceae volume of the Flora of North America (vol. 23). He then informed me that it had been split out of Carex frankii. A species I had seen throughout eastern North America and in which I had never noticed much morphological variation. Trail talk is cheap. For the past year, ...
