230 THE CACTACEAE. 
Our living specimens came from the Organ Mountains, Rio de Janeiro, Brazil, obtained 
by J. N. Rose through Ph. Luetzelburg, September 21, 1915 (No. 21157). 
Dr. Rose examined the type collected by A. O. Darby in 1915 in the Museu Paulista 
and obtained a fragment of it through the kindness of the Director. 
Rhipsalis pulcherrima Lofgren (Monatsschr. Kakteenk. 9: 136. 1899) seems to have 
been the name first given to this plant.

Plate xxxI, figure 2, shows a flowering branch“of the plant obtained by Dr. Rose in 
1915 which flowered in the New York Botanical Garden in 1918 (No. 21151).

Fic. 224.—Rhipsalis lumbricoides. 
Stems terete when growing, but angled when dormant, 3 to 4 meters long, about 6 mm. thick 
rooting freely, much branched; young growth with 5 to 10 white bristles from each areole, usually 
spreading, but old branches naked; flowers white to cream-colored, sometimes tinged with green; 
petals few, often only 5, lanceolate, acute, 10 to 12 mm. long, acuminate; style slender, greenish, 
longer than the stamens; stigma-lobes 4, spreading, greenish; ovary naked; fruit white. 
Type locality: Montevideo, Uruguay. 
Distribution: Uruguay and Paraguay, also probably southern Brazil. Hooker says 
that it is a native of Buenos Aires, but this is doubtless an error. 
This plant flowered in Washington on March 16, 1915. Schumann’s drawing of the 
flower is not very good. 
Rhipsalis sarmentosa (Monatsschr. Kakteenk. 4: 46. 1894) and R. larmentacea (Illustr. 
Hort. 6: 88. 1859) are misspellings for R. sarmentacea. 
According to Lemaire (Cact. Gen. Nov. Sp. 60. 1839) Cereus flagelliformis minor Salm- 
Dyck (Hort. Dyck. 64. 1834) belongs here. Grisebach (Symb. Fl. Argen. 139) referred 
Cereus donkelaarit here.
