Spiny hedgehog cactus (Echinocereus dasyacanthus)
Description
Echinocereus dasyacanthus plants are usually found with a single stem or 2-3 basal branches. Though it is not uncommon to find plants with 3-10 stems. The stems of Texas rainbow cactus are between 11-24 cm long and 5.5-7 cm wide and usually have 15-18 ribs. The spines usually overlap making the stem not visible. There is a great amount of variation in the spines characteristics. There are typically 4-12 central spines that are .5-1.2 cm long and 14-25 radial spines that are .7-2 cm long. The basic coloration of the spines are tan to yellow to pink. Some spines may be ashy-white to reddish brown, but that is less common.
