Echinocereus (spiny Cereus). Cactaceae. Condensed globular, cylindrical or prostrate cacti of the United States and Mexico.
Stems single or cespitose. sometimes forming large clusters of 200-300 sts., distinctly ribbed, usually low in stature, or, if elongated, sprawling or creeping, generally very spiny: fls. yellow, purplish or scarlet, with rather a short funnel-shaped tube; fl.-tube and ovary covered with clusters of spines; stigma-lobes always green. This genus has commonly been merged into Cereus, although it seems to be quite distinct.
Most of the species of Echinocereus are unsuited for greenhouse purposes, for when brought under glass they survive only for a few years. The very large flowers of some species make them very attractive while in bloom. CH
