The different species of Wilcoxia are often, these days,
referred to Echinocereus, on the grounds that the only
thing distinguishing them is their thin stem. They have the same
green stigma which is common in Echinocereus. Still, for the
collector, they form a group with a distinctive appearance.
With time, they form a tuberous root, from which the thin stems
can regenerate if lost, as is more likely in habitat than
when protected in a greenhouse.
