Opuntiastrigil is a prickly pear cactus in west Texas, mostly west of the Pecos River and apparently not entering NM. The Opuntia grows on limestone hills from 2500 to 4500 ft, but also on creosote flats in the Texas trans-Pecos area.
The plants are distinctive in habit, forming sturdy shrubs to nearly 100 cm tall and perhaps as wide composed of nearly circular cladodes. There are 5-8(10) spines per areole with many deflexed but some nearly erect. Centrals on this Opuntia may be 1 to 3 cm long.
Flowers are cream-yellow, but tepals may be orangish in the backside midveins. he anthers are pale. The style is pale cream and stigma lobes are greenish-yellow. Fruits are red and nearly spherical.
Opuntiastrigil is diploid.
The Flora of North America online reports, “Opuntiastrigil is reminiscent of a [small] brown-spined form of O.chloroticachlorotica,” but that is not our experience.
O.strigil is a handsome garden plant, though it may become large in time.
