Description
Echinocereus engelmannii var. variegatusSN|7982]]SN|7982]] is a local or morphological form of the widespread and variable Echinocereus engelmannii. It differs from the type variety mainly for its lowermost central spines mainly 2.8-4.5 cm long, often markedly differing in colour from other spines and varying from white to brown often mottled with black. However the distinguishing characteristics of Echinocereus engelmannii var. variegatusSN|7982]]SN|7982]], appear to fall within the natural variation of Echinocereus engelmannii and it should be synonymized with the latter, but it still has a value for a collector because they identify plants with particular characters.
