Are Clover and Echinopsis both types of cactus?
Echinopsis Echinopsis is a large genus of cacti native to South America, sometimes known as hedgehog cactus, sea-urchin cactus or Easter lily cactus. One small species, "E. chamaecereus", is known as the peanut cactus. The 128 species range from large and treelike types to small globose cacti. The name derives from "echinos" hedgehog or sea urchin, and "opsis" appearance, a reference to these plants' dense coverings of spines.
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.
