Gonaives and La Hotte 



Haiti 



Distribution: Deserts of Haiti and of Azua, Santo Domingo. 



This species, while similar to 0. repens, has more terete joints. 



It was first collected in 1 905 in Haiti by Nash and Taylor, and upon this collection the 

 species was based. In 1913 Rose, Fitch, and Russell collected it in the Azua desert of 

 Santo Domingo. In this last collection the joints are pubescent, but otherwise the plants 

 seem to be the same, although we at one time thought they might be distinct; in fact, in 

 their report on the opuntias, Johnston and Tryon published the Santo Domingo plant as 



new, from notes given to them.

at Azua, Santo Domingo, in 1913.
