Plate xx1x, figure 3, shows a plant also brought by Dr. Rose from Brazil (No. 20662) 
which flowered and fruited in the New York Botanical Garden, March 7, 1921.

Rhipsalis pacheco-leonii Lofgren, Arch. Jard. Bot. Rio de Janeiro 2: 38. 1918. 
In clumps on large limbs of trees and freely rooting; branches very diverse, some with numerous 
bristly hairs from the areoles, others naked, erect, prostrate or even hanging; hairy branches with 9 
very low ribs, the areoles close together, each with about 15 long white bristles; glabrous branches, 
5-angled, with the areoles alternating as in Rhipsalis paradoxa; flower-buds red; flowers solitary, 
about 6 mm. broad; petals few, oblong, obtuse, widely spreading, sometimes turned back, pinkish; 
arn erect, numerous, white; ovary sunken in the branch; style pinkish, erect; stigma-lobes 3 or 
4, white. 
Type locality: Séo Paulo, Brazil. 
Distribution: States of Sdo Paulo and Rio de Janeiro, Brazil. 
We have referred Rhipsalis pacheco-leonii here after studying living specimens of 
R. asinnis and specimens from the type collection obtained by Dr. Rose in 1915 (No. 
20707). 
Rhipsalis setulosa Weber (Hort. Bois Paris) was published as a synonym of R. dissimilis 
var. setulosa.

Plate xxIx, figures 5 and 6, shows the two diverse forms which this plant takes, as does 
also plate xxxu, figures6 and 7. The speciniens were collected by Dr. Rose in the state of 
Rio de Janeiro in 1915 and are a part of the type material of R. pacheco-leonii. 
32. Rhipsalis pentaptera Pfeiffer in Dietrich, Allg. Gartenz. 4: 105. 1836. 
Hartota pentaptera Lemaire, Cact. Gen. Nov. Sp. 75. 1839. 
Branches stiff, bright green, 6 to 15 mm. in diameter, strongly 5 or 6-ribbed, the ribs indented at 
areoles; areoles often 2 cm. apart, small, subtended by broad bracts, usually bearing 2 white bristles; 
flowers usually scattered along whole length of branches, opening in daytime, 1 to 4 from an areole; 
scales 4 or 5 at base of corolla, broad and obtuse; petals 5, reddish on back, cream-colored on face, 
4 mm. long, obtuse; stamens numerous, about 25, free from petals, white, about as long as style; 
style and stigma-lobes white; ovary truncate, naked; fruit 3 to 4 mm. in diameter, white, naked, or 
with an occasional small scale. 
Type locality: Not cited. Otto says, in a note, probably Brazil. 
Distribution: Southern Brazil and Uruguay. . 
A very common species in cultivation, flowering freely in March and April. 
Hariota pentaptera Lemaire and Rhipsalis pentagona are given as synonyms of this 
species by Forster (Handb. Cact. 453. 1846).
