RHIPSAUS. 231 



Figure 224 is from a photograph taken by H. Buch which was given to Dr. Rose when 

 he was in La Plata, Argentina, in 1915. 



19. Rhipsalis aculeata Weber, Rev. Hort. 64: 428. 1892. 



Stems terete, 3 to 4 mm. in diameter, somewhat angled and roughened in dried specimens; 

 areoles close together, bearing wool and 8 to 10 appressed white bristles or spines; fruit not immersed, 

 globose, 7 to 8 mm. in diameter, dark purple to nearly black, either naked or with 3 or 4 hairy areoles. 



Type locality: Catamarca, Argentina. 



Distribution: Northern Argentina, in the provinces of Catamarca and Tucuman. 



A round-stemmed species collected by Otto Kuntze on the Sierra de Santa Cruz, 

 Bolivia, and labeled Hariota sarmentacea may belong here. 



This species is described by Schumann as 8 to lo-ribbed, but no ribs are shown in 

 growing plants ; in drying the branches are somewhat angled but one could hardly describe 

 them as ribbed. Dr. Shafer made a single collection of this plant at Tucuman in 1917 (No. 

 92); part of this material is living in the New York Botanical Garden. Dr. Rose also 

 obtained a specimen through one of his Argentina correspondents from Catamarca. 



Plate XXIV, figure 8, is from Dr. Shafer's plant mentioned above.

Rhipsalis hadrosoma Lindberg, Monatsschr. Kakteenk. 6: 96. 1896. 



Branches divaricate, often reddish, especially about the areoles, stout, 8 to 10 mm. in diameter; 

 flowers numerous, scattered all along branches, 12 mm. long, 2 cm. broad, light rose or cream- 

 colored; sepals reddish; petals few, oblong, obtuse, widely spreading; anthers and style white; stigma- 

 lobes 4, white; fruit naked, purplish, 6 to 7 mm. in diameter. 



Type locality: Not cited. 



Distribution: State of Rio de Janeiro, Brazil. 



We have not seen the type specimen of this species, but through the kindness of Mr. 

 N. E. Brown of Kew we have seen a photograph of Haworth's specimens, which are the 

 same as the species here described. Haworth's plant was received from Brazil in 1816, sent 

 by Messrs. Bowie and Cunningham. 



Rhipsalis calamiformis (Pfeiffer, Enum. Cact. 135. 1837) was published as a synonym 

 of R. funalis. 



Walpers gives Rhipsalis funalis gracilior Pfeiffer (Repert. Bot. 2: 279. 1843) as a 

 synonym.
