Description
Echinocereus viridiflorus v. montanus is a cold hardy species of perennial, succulent plant in the Cactus family (Cactaceae). This is one the several varieties of the morphologically variable Echinocereus viridiflorus, a taxon growing widespread in south and central United States of America. The variety “montanus” is a nomen nudum (undescribed name) sometimes encountered in European nurseries. The name is actually invalid.
Habit: The “mountain” form of Echinocereus viridiflorus corresponds to the plants in our collections known as var. montanus. This variety grows significantly depressed (mostly less than 2 cm tall), solitary or in low clusters and was probably collected in Colorado. The absence central spines, or vice versa an exceptionally long and stout central spine, led to the isolation and selection of other horticultural varieties without taxonomic significance.
