Rhipsalis crassa Schumann, Keys 54. 1903. 
Stems much jointed, pendent; joints often 3 to 6 dm. long, 5 to 7 cm. broad, thickish, stiff, 
sometimes nearly orbicular, often purple, deeply crenate; flowers numerous, but solitary, rarely 
2 to 4 from the areole, large; petals widely spreading, yellowish; stamens numerous; stigma-lobes 
4 or 5, slender; fruit globose, white. 
Type locality: Originally given as the West Indies,* but this is doubtless a mistake. 
Distribution: States of Rio de Janeiro, Minas-Geraes, Santa Catherina, and Sao Paulo, 
Brazil. 
The species grows in the high mountains on trunks of trees, altitude 1,000 meters, down 
to nearly sea-level. 
A variety, crassior Salm-Dyck (Pfeiffer, Enum. Cact. 132. 1837), with thick green 
orbicular joints, has been described. 
Steudel’s name of Rhipsalis alata (Nom. ed. 2. I: 333. 1840), given as a synonym of 
Cereus alatus De Candolle, is referred here by Schumann, but probably relates to Pseu- 
dorhipsalis. _ 
This species was for a long time confused with Rhipsalis alata, a very distinct species 
from Jamaica, now referred by us to the genus Pseudorhipsalis.
