Wright's plant was distributed as P. portulacifolia and so 
recotded by Grisebach, but that species of Hispaniola has quite 
different leaves, as is shown by the old illustration of Cactus portu- 
lacifolius L.is based (Plumier, ed. Burmann, pl. 197. f. т) and by 
specimens collected by Buch in Haiti, examined by Professor 
Urban. 
A similar, perhaps identical, species grows on La Vigia Hill, 
Trinidad, Province of Santa Clara (Britton & Wilson 5513).

apart; spines 2—5 at each areole, acicular, pale yellow when 
oii: becoming Жун жы, the longer 5 cm. long or less;
