RHIPSALIS. 227 



Hitherto unknown wild within the continental United States, the plant was found 

 on August 5, 1923, by C. A. Mosier on trees in Wallenstein's Hammock, Dade County, 

 Florida. 



Cactus cassythoides Mocifio and Sesse was given by De CandoUe (Prodr. 3: 476. 1828) 

 as a synonym of R. cassytha mocmiana. 



Lofgren (Arch. Jard. Bot. Rio de Janeiro 2: 40. pi. 11. 1918) has figured and described 

 as new a plant under the name of Rhipsalis cassythoides which may belong here. The name 

 had already been used by Don and we have referred it as a synonym of R. cassutha. 



Cactus epidendrum Linnaeus (Amoen. Acad. 8: 257. 1785) is without description and 

 has been referred to Rhipsalis undulata. It was from Surinam. 



Cereus bacciferus (Hemsley, Biol. Centr. Amer. Bot. i: 548. 1880) appears only as a 

 synonym of Rhipsalis cassutha. 



Cassytha baccifera Miller (De Candolle, Prodr. 3: 476. 1828) and C. polysperma Aiton 

 (Gaertner, Fruct. Sem. PI. i: 137. 1788) are known in synonymy only. 



Rhipsalis pendula Hortus (Pfeiffer, Enum. Cact. 133. 1837) occurs only as a synonym. 



Rhipsalis caripensis Weber is listed as one of the sjoionyms of this species by Schumann 

 (Gesamtb. Kakteen 622. 1898). 



Rhipsalis cassytha vars. major and pilosiuscula (Salm-Dyck, Hort. Dyck. 228. 1834) 

 and var. tenuior (Schumarm, Monatsschr. Kakteenk. i : 78. 1891) are only names. The first 

 has been referred to R. floccosa, while the second is sometimes referred to R. pulvinigera.
