Spiny Hedgehog Cactus

Echinocereus dasyacanthus (species)

On the Web

On Wikipedia

Echinocereus dasyacanthus is a member of the cactus family, Cactaceae. It is one of about 2000 total species belonging to this family. The cactus is commonly known as Texas rainbow cactus because of the subtle rings or bands of contrasting colors along the stem of the plant. Not all Texas rainbow cacti have the "rainbow" coloration on their stems. Another common name is spiny hedgehog cactus. E. dasyacanthus can be identified as a tetraploid with predominantly yellow flowers. Experiments suggest this is due to the hybridization of E. dasyacanthus and E. coccineus. The E. dasyacanthus received its specific epithet from the two Greek words dasys and akantha, which mean "shaggy" and "thorns" respectively.
