Echinocereus triglochidiatus

Echinocereus triglochidiatus is a species of hedgehog cactus known by several common names, including kingcup cactus, claretcup, and Mojave mound cactus. This cactus is native to the southwestern United States and northern Mexico, where it is a resident of varied habitats from low desert to rocky slopes, scrub, and mountain woodland. It is most abundant in shady areas. 
A number of varieties of this highly variable cactus species are known, but not all are universally recognized. In general, it is a mounding cactus, forming bulbous piles of a few to hundreds of spherical to cylindrical stems. It is densely spiny and somewhat woolly. The showy flower is a funnel-shaped bloom up to 8-9 cm wide and bright scarlet red to orange-red tepals. A thick nectar chamber and many thready pink stamens are at the center of the corolla. The flowers are pollinated by hummingbirds.
One variety," E. t." "arizonicus", is federally listed as an endangered species in the United States. It is limited to the intersection of Arizona and New Mexico in the United States with Mexico. This variety is sometimes included within "Echinocereus coccineus".
The conservation status of several subspecies differs from that displayed. Examples include:
" E. triglochidiatus" is the official state cactus of Colorado.
Etymology.
Presumably, the specific epithet comes from "tri-" and "glochidium", with a meaning of "having three arrow points".
