Description
editEchinocereus subinermis grows either solitary or branching, often forming groups of up to 10 shoots. The stem is a ball with gray-green to reddish, 5 to 11 prominent ribs, growing to a cylinder or cone 4–33 cm (2–13 in) 4 to 15 tall and wide, and producing yellow flowers 8 cm (3 in) long in early summer. There are up to four central spines, which may be light or dark and are 0.1 to 2 centimeters long, although they can also be absent. The plant may also have up to ten slender, light yellow to gray marginal spines that are 0.1 to 3 centimeters long, but these too can be absent.[1] The flowers are funnel-shaped, fragrant, and bright yellow, appearing near the shoot tips. They are 7 to 10 centimeters long and 5 to 13 centimeters in diameter. The gray-green, obovate fruits are thorny, contain white pulp, and split lengthwise when ripe.[2]

Taxonomy
editFirst described by Frederick Scheer in 1856, the specific epithet "subinermis" comes from the Latin words "sub-" meaning 'almost' or 'more or less,' and "inermis," meaning 'unarmored,' referring to the species' short thorns.[5]
Cultivation
editIn cultivation in temperate regions it requires the protection of glass with heat. It has gained the Royal Horticultural Society's Award of Garden Merit.[6][7]
