Echinocereus metorni is a tiny gem of
Sierra Mojada (Big Bend Texas).
The flowers are quite large for such a small plant.
Echinocereus metorni is a tiny slowly clustering cactus
with a quite a large flower for such a small plant. Flowers will be
expected in 2-5 (or more) years old seedling when they mature.
Remarks: The classification and the relationship of the plant
belonging to the E. chisoensis group (Echinocereus
fobeanus, Echinocereus metornii and Echinocereus
chisoensis) is still controversial, all this species are
considered synonyms of E. chisoensis, but there is quite a
variation in the habitus (spination and shape of the plant, form of
flower bud and receptacle tube, color-zonation in the flower, size of
nectar chamber, form of fruit chamber and in the size, form and surface
structure of the seed.) The morphological variation are also reconfirmed
by chemical and genetic test.
Therefore synonymizations seems to be the result of invalid
interpretations of the relationship.
subspecies, varieties and forms:
The E. chisoensis type has stems that are not constricted
annually. The flowers are 6 cm long with the inner perianth segments

is sensitive to overwatering (rot prone) needs a very good drainage to
