The Vasculum

In early September, I took a little trip to eastern Wyoming. It wasn't the best time of year to visit the Great Plains since late summer is predominantly crispy and brown on the Shortgrass Prairie. However, I was able to find some color here and there. The area receives an average of 12 inches of precipitation annually. These arid conditions have resulted in a significant percentage of annuals in the flora. Cryptantha crassisepala (photo below) is a fine example. The hairs of the inflorescence are very stiff and are quite pleasing to the touch. With its numerous scorpioid cymes the plant is visually pleasing as well. In the very center of the photo is the final flower of what would have earlier been a much prettier display. Here on the Great Plains, as with much of Earth's surface, anthropogenic disturbance has significantly altered the ecological integrity of the presettlement natural communities and dramatically changed the natural distribution of plants and animals.

I don't know if it was the cool temperatures, the abundant rainfall or some other stochastic influence, but Gaura biennis was extremely flamboyant in the Ozarks this summer. Everywhere I went, large, diffuse inflorescences of white turning to shades of pink were found. Admittedly, I have mostly ignored Gaura biennis over the years; finding it gangly and somewhat weedy. But it really out-did itself this year and I took notice. Camera in hand, tripod in tow, I headed down my gravel driveway to a nice specimen for a quick photo. Knowing them to be nocturnal bloomers and having noticed that the flowers were at their peak in the morning when I left the house and mostly shriveled by my evening return, I got to them just after sunrise. After taking some quick photos, the kind where you don't really see the subject for the equipment, while rushing to beat the light, wind or self-imposed time constraints, I began to study the flowers. In this conscious effort to slow-down and enjo...
