Cochemiea thomasii
A small clustering cactus from the lowland hills of central Sinaloa, Mexico, recently moved from Mammillaria into Cochemiea along with its hooked-spined relatives. It lives with a hot, bone-dry spring and a short, intense summer monsoon, so it wants strong light, heat and a firm dry rest in the cooler months.
Where it grows wild
Recorded from a tight cluster of sites in central Sinaloa, in low hills of tropical dry deciduous forest and thornscrub. Like related Cochemiea it most likely grows on rocky slopes among shrubs and grasses, getting strong sun with some light shade from leafless trees.
The single climate site sits around 270 m; the species appears to be a lowland plant of the Sinaloan foothills below roughly 500 m.
