Are Dissotis and Millettia species?
Millettia Millettia is a genus of legume in the Fabaceae family.
Dichanthelium oligosanthes Dichanthelium oligosanthes (common names: Heller's rosette grass, fewanther obscuregrass, few-flowered panicgrass) is a frost tolerant perennial wild grass species found primarily in the contiguous United States with specimens also reported in British Columbia and Alberta in Canada, as well as south of the Rio Grande in northern Mexico. It is found most frequently in partially shaded glens within woods, recently cut forests, and grassy banks. The species is primarily cleistogamous, with individual florets often self pollinate without opening. Despite being a member of the grass subfamily Panicoideae which includes many species which utilize C4 photosynthesis, "D. oligosanthes" retains the more ancestral trait, using a C3 photosynthetic pathway.
