ZYGOCACTUS. 



179 



Epiphyllum ruckeri Paxton (Mag. Bot. 12: 46. 1846) was described from cultivated 

 plants of unknown origin as an improved variety of Epiphyllum truncatum. It may have 

 been a hybrid. 



Epiphyllum truncatum multiflorum was given as a synonym of Epiphyllum altensteinii 

 by Pfeiffer (Enum. Cact. 128. 1837). 



Epiphyllum elegans Cels and E. violaceum Cels (Forster, Handb. Cact. 446. 1846) were 

 supposed to be only varieties of Epiphyllum- truncatitm. 



Schelle (Handb. Kakteenk. 223. 1907) lists more than fifty forms of Epiphyllum 

 truncatum ; the following not hitherto mentioned by us under Epiphyllum have the regular 

 Latin form: 



araabile roseum 



carmineum 



gracile 



grandiflorum rubrum 



harrisonii 



lateritium album 



makoyanum
