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 (No. 20708) which flowered and fruited in the New York Botanical Garden 
in 1922. 
55. Rhipsalis oblonga Lifgren, Arch. Jard. Bot. Rio de Janeiro 2: 36. 1918. 
In cultivation bushy; main branches terete below, more or less flattened above; ultimate 
branches narrowly oblong, 5 to 15 cm. long, 1 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 Wha Grande, Brazil. 
Distribution: Known only from the type locality. 
Illustration: Arch. Jard. Bot. Rio de Janeiro 2: pl. 8, as Rhipsalis oblonga. 
Plate xxxv, figure 1, shows the plant grown by Dr. Lofgren at Rio de Janeiro and given 
to Dr. Shafer in 1917, which flowered and fruited in the New York Botanical Garden in 
May 1922. 
56. Rhipsalis cuneata sp. nov. 
Epiphytic on trees; jcints oblong to spatulate, 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. 
Fic. 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 fiir Sukkulentenkunde 1: 22. 1923. 
Lower joints flat, 15 to 20 mm. broad, distinctly alternately notched; areoles small, with a little 
tuft of white wool and a single short brown hair, 15 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 
10 mm. broad and only shallowly notched, others triangular with prominent notched angles and 
excavated sides, others 1 cm. wide, with 3 or 4 prominent wing-like distinctly 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 Popay4n, 1922. | 
Mr. Berger writes: ‘‘ 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. wercklei.
