It was first described in 1838 by Michael Joseph François Scheidweiler as Echinocactus pectinatus . George Engelmann introduced the species to Echinocereus in 1848 .
There are a lot of invalid double descriptions and recombinations and a multitude of synonyms .
The following subspecies are distinguished:
- Echinocereus pectinatus subsp. pectinatus
-
Echinocereus pectinatus subsp. lessi (LDBenson) W.Blum & Rutow :
The subspecies was originally described by Lyman David Benson in 1968 as a variety of Echinocereus pectinatus . Wolfgang Blum and Jürgen Rutow combined them in 1998 as a subspecies to Echinocereus pectinatus . The subspecies occurs predominantly in east Texas. It typically always has 1 to 3 central spines and magenta-colored flowers.
In the Red List of Threatened Species of the IUCN , the species is listed as " Least Concern (LC) ". H. listed as not endangered.
