Echinomastus erectocentra var. erectocentra


Echinomastus erectocentrus var. erectocentrus is a small cactus that can grow up to 6 inches in height. Plants have central spines that point upward. Variety erectocentra and var. acunensis are virtually indistinguishable, and may not be taxonomically distinct, according to Dr. Don Pinkava of Arizona State University (pers. comm. 1991). Characters based on size and flower color were formerly used to separate the two taxa, but these may not be accurate indicators. Geographic range is now used to separate the two, with var. erectocentra occurring in the general Tucson area east and south to the Mexican border, and var. acunensis in northern Sonora, Organpipe National Monument, northward and east to the Florence area. Variety erectocentrus grows on alluvial fans and hills, usually limestone at elevations of 1300-2000 ft.
