Vaupel has recently pubHshed an article (Zeitschrift fiir Sukkulentenkunde i: 19. 1923) in which he states that the type was cultivated in the Botanical Garden of Berlin in 1833 and that specimens are now preserved in the herbarium there. He states that these are the same as the plant collected by Ule at Seringal, San Francisco, in the Upper Acre region of Brazil, about 10° south latitude, towards the border of Bolivia and Peru. He would also refer here a plant collected by Tafalla in 1790 at Pozugo in eastern Peru. Cactus dentatus Ruiz (Martins, Fl. Bras. 4-: 288. 1890), given as a synonym of Rhipsalis alata by Schumann, is based on Tafalla's plant and according to Vaupel should not have been credited to Ruiz. Epiphyllum ramulosuni, E. ciliare, and E. ciliatum were all given by Pfeiffer (Enum. Cact. 130. 1837) as synonyms of Rhipsalis ramulosa. Figure 229 shows a drawing made from Mr. Williams's Fig. 229.—Top of fruiting branch of Rhipsalis ramulosa. 45. Rhipsalis purpusii Weingart, Monatsschr. Kakteenk. 28: 78. 1918. Plant epiphytic; stems 8 mm. in diameter, woody, terete, brown; branches weak, elongated, terete below, flattened above, thin, remotely crenate; flowers small, white, solitary. Type locality: Cerro de Boqueron, Chiapas, Mexico. Distribution: Known only from the type locality. This must be related to the Costa Rican plant, Rhipsalis coriacea, and perhaps conspecific.
