Plate xxxvir, figure 5, shows a fruiting branch of the type collection obtained by Dr. 

 Rose on Ilha Grande near Rio de Janeiro in 1915 (No. 20401). Figure 231 is from a photo- 

 graph of Miss Eaton's painting of a plant given to Dr. Shafer by Dr. Lofgren in 19 17 at 

 Rio de Janeiro which flowered in the New York Botanical Garden in May 1922.

Fro. 232. — Rhipsalis crispata. 



Branches divided into short flat joints 6 to 10 cm. long, broad both at base and apex, green, 

 more or less crenate; flowers solitary or sometimes 2 to 4 at an areole, 10 to 12 mm. broad, cream- 

 colored to light yellow; filaments numerous; fruit white, 7 mm. in diameter. 



Type locality: Brazil. 



Distribution: Brazil, but range unknown. 



The synonyms R. oris pa and its var. major (Forster, Handb. Cact. 450. 1846) and 

 R. crispa latior Salm-Dyck (Walpers, Repert. Bot. 2: 279. 1843); Hariota crispata latior 

 Lemaire (Cact. Gen. Nov. Sp. 75. 1839) doubtless belong here. Schumann, in Nachtrag, 

 page 144, refers here Rhipsalis swartziana Pfeiffer. 



Pfeiffer publishes as a sjoionym of the above Cereus crispatus (Enum. Cact. 130. 1837), 

 as does also Forster. Schumann (Gesamtb. Kakteen 638. 1898) makes this species a 

 variety of Rhipsalis rhombea, but later (Gesamtb. Kakteen Nachtr. 145. 1903) recognizes 

 two species. 



Cactus torquatus (Walpers, Repert. Bot. 2: 342. 1843), referred to Rhipsalis rhombea 

 by Walpers, w.as only a garden name.
