Description

The so called "grandicornis" is a solitary (or rarely branching) plant, considered by many only one of the many forms of Stenocactus crispatusSN|3443]]SN|3443]]. It is characterized by particularly long central spines and wavy ribs. The plant found in cultivation are quite variable, and the dissimilarity among seedlings spination may be considerable.

Radial Spines

Usually 4 to 6 flattened, whitish to brownish, 0,5 to 1 cm long and about 0,6-1 mm wide at the base.

Fruits

8-12 mm long, 4-6 mm wide, obovoid reddish to greysh, dry at maturity.
