Description:

Description: English: Over the past 10 years, thesium has been slowly increasing in abundance on this southwest facing slope, which used to have more shrub cover. Now this slope is dominated mainly by a mix of of grass. These are, in order of abundance, Kentucky bluegrass (Poa pratensis), western wheatgrass (Agropyron smithii), crested wheatgrass (Agropryon cristatum), and Prairie junegrass (Koeleria macrantha). Thesium is the rusty-yellow fine-stemmed cover with a spreading rhizomatous grown habit. The trifoliolate leaves in which the flower and fruit sit up on the leaf in the axil of the three leaflets is a very distinguishing trait of thesium. Date: 4 August 2016, 09:09:14.
