 only representative of the order in the Old World is Rhipsalis, found 

 in Afr., Mauritius, &c., but several sp. of Opuntia, &c. are now nat. in 

 S. Afr., Austr., &c. and becoming troublesome.

 better based upon them than upon the repr. organs. R. generally 

 long and well-developed (in cultivation liable to decay). Stem
