246 THE CACTACEAE. 



Plate XXXV, figure 3, shows a flowering plant received from A. Berger in 1908. Figure 

 232 is from a photograph of Miss Eaton's painting of the plant obtained by Dr. Rose in 

 Brazil in 1915 (Xo. 20708) which flowered and fruited in the New York Botanical Garden 

 in 1922. 



55. Rhipsalis oblonga Lofgren, Arch. Jard. Bot. Rio de Janeiro 2: 36. 1918. 



In cultivation bushy; main branches terete below, more or less flattened above; ultimate 

 branches narrowl}- oblong, 5 to 15 cm. long, i to 2 cm. broad, shining green even in sunlight; flowers 

 borne along the sides of the branches, solitary at the areoles ; fruit globular to short-oblong, 3 to 4 

 mm. long, nearly white, naked, crowned by the withered perianth. 



Type locality: On Ilha Grande, Brazil. 



Distribution: Known only from the type locality. 



Illustration: Arch. Jard. Bot. Rio de Janeiro 2: pi. 8, as Rhipsalis oblonga. 



Plate XXXV, figure i, shows the plant grown by Dr. Lofgren at Rio de Janeiro and given 

 to Dr. Shafer in 19 17, which flowered and fruited in the New York Botanical Garden in 

 May 1922. 



56. Rhipsalis cuneata sp. nov. 



Epiphytic on trees; joints oblong to spatula te, 8 to 12 cm. long, thin, obtuse, cuneate at base, 

 strongly crenate, naked at the areoles or with a bristle or two; flowers so far as known solitary; 

 fruit globose, 4 mm. in diameter, naked. 



Fig. 233. — Rhipsalis cuneata. 



Collected by R. S. Williams above San Juan, Bolivia, altitude 5,500 feet, April 2, 

 1902 (No. 2458). This species is known to us only from herbarium specimens. 

 Figure 233 is from a photograph of the specimen in the U. S. National Herbarium. 



57. Rhipsalis roseana Berger, Zeitschrift fxir Sukkulentenkunde 1: 22. 1923. 



Lower joints flat, 15 to 20 mm. broad, distinct^ alternate^ notched; areoles small, with a little 

 tuft of white wool and a single short brown hair, 1 5 to 20 mm. apart, the upper ones more closely set ; 

 upper joints narrower and more linear or linear-lanceolate, 10 to 15 mm. broad and 6 to 12 cm. long 

 or more, equally notched, smooth, bright green; some of the uppermost joints often narrower, 8 to 

 ID mm. broad and only shallowly notched, others triangular with prominent notched angles and 

 excavated sides, others i cm. wide, with 3 or 4 prominent wing-like distincth' but remotely notched 

 ribs and areoles about 4 cm. apart; flowers small, whitish yellow. 



This species was described from cultivated plants of unknown origin. We believe 

 that it may be from Colombia and we would refer here the following specimens: Wilson 

 Popenoe's No. 518 from near San Miguel, Perdoma, Tolima, 1921, and Ellsworth P. 

 Killip's No. 8203 from mountains west of Popayan, 1922. 



Mr. Berger whites: "This new Rhipsalis is decidedly distinct from R. wercklei; its 

 branches are shorter, broader, more deeply notched and of a firmer nature. Its growth too 

 is far less quick and it does not form so promptly long and pendent shoots as R. ivercklei.
