Echinomastus erectocentrus var. erectocentrus Needlespine
CACTUS. A small cylindrical or egg-shaped cactus with long thin
white and purple spines. Central spines 1 or 2, erect, dark purple,
longer than the radial spines. Flowers white, washed with pale pink
or purple, with green centers. Stigma pinkish red, style yellow,
stamens yellow. Blooms in March-April. Appears to be endemic
to the Empire Mountains and surrounding area. Its natural range is quite
small, and the Empires hold the largest and healthiest populations.
Here it is common on flat ground or gentle slopes in limestone, marble,
or mixed carbonate/volcanic gravel. Associated plants may include
Calliandra eriophylla, Tiquilia canescens, Larrea tridentata, Parthenium
incanum. Escobaria vivipara is similar but radial spines
are white, central spines are brown and horizontal, and flowers are bright
pink and bloom later. See my E. erectocentrus page for more
photos and information.
