Opuntia nemoralis
Opuntia nemoralis is a species of cactus (Cactaceae) native to the United States. It is found in the South-Central region, in the states of Arkansas, Louisiana, Texas, and with a single specimen tentatively identified from Missouri. Its natural habitat is in sandy prairies, saline and sodic barrens, and rock outcrops.

"Opuntia nemoralis" has long been considered a synonym of "Opuntia humifusa". However recent genetic analysis, in combination with distinct morphological features, suggested that recognition at the species level of many entities previously included under "O. humifusa" was warranted. In 2017 "Opuntia nemoralis" was resurrected as a species.

"Opuntia nemoralis" is closely related to "Opuntia cespitosa". "O. nemoralis" can be distinguished by its smaller size, narrower cladodes that more easily disarticulate, barbed spines, and tepals that are yellow (rarely faintly pink) to the base.
