Stems light green, but often becoming deep purple throughout, often 3 em. in diameter; ribs 

 4 or 5, rarely 3 or 6, rather prominent but less so on the older branches; areoles small, white; spines 

 1 em. long or less, brownish; reflexed 

 bristles or hairs from the lower part of 

 the areoles several, white, longer than 

 the spines; flowers 20 to 30 em. long; 

 uppermost scales and outer perianth- 

 segments narrow, brown to orange, paler 

 within; inner perianth-segments spat- 

 ulate to oblanceolate, the upper part 

 more or less serrated, the very broad 

 apex sometimes apiculate or entire and 

 acuminate, pure white; stamens and 

 style yellowish green, longer than the 

 inner perianth-segments; flower-tube 17 

 cm. long, reddish brown, its areoles and 

 those of the ovary bearing long, white 

 hairs. 



Type locality: Haiti. 



Distribution: Cuba and Hispan- 

 iola. 



Plants collected by Dr. John K. 

 Small, escaped from cultivation near 

 Halendale, Florida, are, apparently, 

 referable to this species.
