Opuntia rastrera

Opuntia rastrera is a prickly pear which grows in the Mexican state of San Luis Potosí.[1] It is known in Spanish as cuija,[2] although that name can also refer to other cactuses such as Brasiliopuntia.

Description

Opuntia rastrera can be found in bajada, hill-piedmont, and interdune habitats in locations such as the Mapimi biosphere reserve, where it is sometimes the most common cactus in a given location, or sometimes a secondary cactus.[3]

Propagation

In order to germinate, the seeds require a dormancy period of at least a year. As with other Opuntia species, mechanical or chemical scarification does not seem to help.[4]

The species can reproduce either vegetatively or by seed. In fact, the nature of the habitat determines which is more common, with sexual reproduction dominating in grasslands and vegetative propagation dominating in scrublands.[5]

gollark: I've seen two leetle trees in a few hours of hunting, but not a single xenowyrm.
gollark: But yes, quite neat.
gollark: I'm not really a fan of holiday ones.
gollark: Does anyone have any tips for gathering cavey eggs, by the way? Other than "click fast", that is.
gollark: Ah, the irony of the eggs which could speed up hatchings being stuck hatching...
