Echinocereus dasyacanthus
species of plant
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.
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.
This brief starts where responsible research should: with the source description of “Echinocereus dasyacanthus” as species of plant. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of plant. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Mar 26, 2026. The linked authority identifier is Q151215. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2000.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
