Rhipsalis roseana Berger, Zeitschrift fur Sukkulentenkunde 1: 22. (1923).

Treated as a synonym of R. micrantha by Calvente in Thesis 2010
Reduced to synonymy under R. micrantha f. rauhiorum by Barthlott and Taylor Bradleya 13
  • Plant 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 prominently
    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 Miquel, Perdoma, Tolima, 1921, and Ellsworth P. Killip's No.8203 trom mountains west of Popayan, 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."
