Details

Opuntia cymochila was originally described from near Tucumcari, NM. The synonym oplocarpa was used for plants from Golden, CO, and the synonym fusiformis was used for plants from eastern KS and Fort Smith, AK. The species also occurs in WY; the Dakotas and various Midwestern states; northern, central, and western TX; NM; and southeastern UT. (Britton and  Rose reported that O. cymochila was found from WI to SD, TX, KS, CO, and NM.) Its range in Mexico is unclear. It is the dominant grassland species of Opuntia that has juicy fruit (O. polyacantha has fruit that is dry at maturity). See a table comparing O. cymochila with O. tortispina. See the original description. O. cymochila is hexaploid.
