Plant globose or somewhat depressed, 15 to 20 cm. in diameter; ribs 17 or 18, rather prominent, 

 thin, strongly undulate, pale bluish green; areoles somewhat immersed in the rib; spines rigid, brown- 

 ish; radial spines 10, spreading, or somewhat recurved, 12 to 16 mm. long; central spine solitary, 25 

 mm. long, ascending, curved; flowers lateral, white or purplish, the tube 20 cm. long, green; scales 

 on ovary and flower-tube acuminate, bearing an abundance of black hairs in their axils; inner 

 perianth-segments large, serrate, mucronate. 



Type locality: Bolivia. 



Distribution: Bolivia. 



This plant was collected by Mr. 

 Thomas Bridges in Bolivia in 1844 and 

 first described by Salm-Dyck in 1845 as 

 Echinocactus obrepandus, but when in 1850 

 he transferred it to Echinopsis he changed 

 the specific name to cristata. A part of 

 Bridges's material went to Kew; one of 

 the specimens produced purple flowers, 

 and another nearly white flowers ; there is 

 a possibility that more than one species 

 was collected by Bridges at this time. The 

 figures given in Gartenflora (38: f . 47) and 

 Monatsschrift fur Kakteenkunde (12: 169) 

 are not quite typical. Here Weber refers 

 Echinopsis obliqua Cels (Diet. Hort. Bois 

 472. 1896). 



The plant is known to us only from 

 descriptions and illustrations.
