Rhipsalis cribrata Léfgren, Arch. Jard. Bot. Rio de Janeiro 1: 81. pl. ro. 1915. Not Riimpler, 1885. 
Much branched, very weak, with long slender hanging branches, the branching usually dichot- 
omous; ultimate branches usually 4 to 10 cm. long; flowers subterminal, campanulate, 10 to 12 mm. 
long, white; fruit turbinate, rose-colored. 
This plant is very common in the forests about Sao Paulo. Dr. Rose collected it in the

of Museu Paulista on August 14, 1915 (No. 20849). 
This species is named for William John Burchell (1781-1863), who went to Brazil in 
1825, where he made large and valuable collections.

species have been, through sendings of orchids, where it was discovered by Lemaire, and 
when it flowered the following year it was named and described by him. 
Hariota penduliflora (Monatsschr. Kakteenk. 1: 69. 1891) is listed but not described. 
- Rhipsalis penduliflora laxa, referred to by Schumann (Martius, Fl. Bras. 4°: 276. 1890),
