Xerophyte

Note

Stenocactus obvallatusSN|6285]]SN|6285]] is an exceedingly variable species throughout its range and some taxonomists recognize several varieties and even distinct "species". The segregation of the many forms, varieties, and subspecies on the basis of morphology, however, is difficult to support, given the continuous range of variation in stem size and flower colour over its geographic range.

Flowers

1-2 cm long can be up to 3-4cm in diameter. E. obvallatus has white or pale yellow flowers with pink mid-veins and a greenish base. The plants known as Stenocactus pentacanthusSN|6296]]SN|6296]] have long lasting flowers in early spring.

Spines

"pentacanthus" means five spined, of this 5 spines there are 3 major on the upper part of the areoles
