Alt. Name:
Name for a plant collected in Texas. There are no Echinopsis in Texas, so it is most probably an Echinocereus. As no type specimen, no picture nor a type locality are known it is a very doubtful plant.
Nevertheless it has been used as a basionym for different Echinocerei:
Echinocereus octacanthus (Mühlenpfordt) Britton & Rose,
The Cactaceae 3 Page13 is an Echinocereus coccineus subsp. roemeri
Echinocereus octacanthus (Mühlpf.) Br. & R. in Backeberg,
Die Cactaceae 4 shows on page 2067 an Echinocereus hybrid.
Echinocereus triglochidiatus var. octacanthus (Muehlenpf) sensu W.T. Marshall, Cactaceae (Marshall Bock) 118.1941 is an Echinocereus coccineus subsp. roemeri
Echinocereus triglochidiatus var. octacanthus (Muehlenpf.)
Marshall sensu Weniger CACTI OF THE SOUTH-WEST
Page 39 + Plate12 shows an Echinocereus coccineus subsp. paucispinus
