This plant was seen at only one locality and only small specimens were observed, but much larger ones may be expected. This is a densely armed plant, peculiar in having all the straight dagger-like strong central spines ascending. According to letters from F. Vaupel, this plant has been in cultivation in Germany for several years, grown from seed, perhaps from the type collection. It is briefly mentioned in the Monatsschrift fur Kakteenkunde (29: 13. 1919) as Echinocactus santa-maria Rose. 11.

Paris 4: 100. 1898. Plants very stout, usually 1 to 2 meters, but sometimes 3 and 4 meters, high, 6 to 8 dm. in diameter or more; ribs numerous, sometimes as many as 39, rather thin; areoles large, 1 to cm. long, somewhat elliptic, approximate or on old plants coalescent; spines 6 to 8, yellow, subulate, 3 to 4 cm. long, slightly curved and a little spreading; flowers numerous, 3 to cm. long; scales on ovary and flower-tube ovate, closely imbricate, thin on the margin and somewhat lacerate; inner perianth-segments red with yellow margins, oblong, 2 cm. long; filaments pink, numerous; tube of flower below stamens very short; style yellow; fruit scaly. Type locality: Santa Catalina Island, off Lower California. Distribution: Islands of the Gulf of California. This species which is common on several of the islands in the Gulf of California is perhaps the largest of all the visnagas or barrel cacti. On Santa Catalina Island, especially, enormous individuals are to be found and here it is the most conspicuous plant. It seems to have no very definite habitat, growing both on the mountain sides among the large igneous rocks as well as along the old shell beaches. These plants have an enormous display of surface roots with only a few weak supporting ones and consequently large plants can easily
