234 THE CACTACEAE. 
species is perhaps nearest Rhipsalis floccosa, from Brazil, and is the most northern repre- 
sentative of the Series Floccosae. . 
Plate xxiv, figure 6, is of a fruiting specimen of the type plant. 
26. Rhipsalis pulvinigera Lindberg, Gartenflora 38: 186. 1889. 
Rhipsalis funalis minor Pfeiffer, Enum. Cact. 135. 1837. 
Plant epiphytic, rather stout, at first erect but in time hanging, and then sometimes 3 to 5 
meters long, the branches dull green with purple about the areoles, 5 to 7 mm. in diameter; terminal 
branches often in whorls of 3 to 5; flowers at first white, in age yellowish, 2 cm. broad; ovary sunken 
in the branch; fruit globose, red, 8 mm. in diameter. 
Type locality: Brazil. 
Distribution: In the coastal mountains of central Brazil. 
Schumann gives Rhipsalis grandiflora minor (Gesamtb. Kakteen 644. 1898) as a 
synonym of this species, but he evidently meant R. funalis minor. 
Rhipsalis cassytha pilosiuscula Salm-Dyck (Hort. Dyck. 228. 1834), although never 
described, probably is to be referred here.

1915, which fruited in the New York Botanical Garden in 1915 (No. 43060).

Rhipsalts rugulosa Lemaire, Illustr. Hort. 8: after pl. 293. 1861. 
Hartota rugosa Kuntze, Rev. Gen. Pl. 1: 263. 1891. 
Stems slender, 5 to 8 mm. in diameter, much branched, at first erect, becoming pendent; branches 
alternate; flowers lateral, 2 cm. broad, white, tinged with yellow, surrounded by a tuft of wool; 
ovary sunken in the branch; fruit globose, 5 mm. in diameter, rose-colored or nearly white. 
Type locality: Not cited. 
Distribution: Brazil. 
Rhipsalis cassytha major Salm-Dyck (Pfeiffer, Enum. Cact. 1 34. 1837), a Synonym 
only, is referred here by Pfeiffer. 
Hartota floccosa Cels was used as a synonym by Forster (Handb. Cact. 458. 1846), but 
was not technically published until 1891.

Plate xx1x, figure 1, shows a flowering branch from a specimen sent by Mr. Lamb 
from Manchester, England, in 1914, and figure 2 shows a flowering branch collected by 
Dr. Rose in Brazil in 1945 which flowered in the New York Botanical Garden on February 
24, 1922. 
28. Rhipsalis tucumanensis Weber, Rev. Hort. 64: 426. 1892. 
Hartota tucumanensis Kuntze, Rev. Gen. Pl. 37: 107. 1898.
