Coryphantha echinus is a species of cactus known by the common names of sea urchin cactus, hedgehog Cory cactus[2] or rhinoceros cactus.[3]C. echinus is found in the south and east portion of the Trans-Pecos to Del Rio, Chihuahua, Coahuila and sporadically in the northeast Trans-Pecos.[2] The plant normally occurs in solitary groupings, but sometimes grows as a clump.[4] It produces short-lived yellow flowers that last for a couple of hours between April and July.[4][2] After flowering, it produces green fruits.[2]
Coryphantha echinus was first collected by Charles Wright in 1849 and was later described as Mammillaria echinus by George Engelmann.[2]
