Specific Name and Character. 



Rhipsalis brachiata; erecta ramosissima, ramis sparsis tere- 

 tibus articulatis punctatis, ramulorum articulis brevi- 

 bus, ultimis apice barbatis, floribus in rarnulis inferi- 

 oribus terminalibus solitariis, stylo exserto. 



This new species of Rhipsalis was received by Mr. Moore 

 at the Glasnevin Botanic Garden from Mr. Tweedie at 

 Buenos Ayres, and it produced its flowers with that able 

 cultivator in the month of March, 1843. It is very differ- 

 ent from any of the sixteen species described by Pfeiffer. 

 Indeed, of those sixteen, it could only be associated with 

 the species in that author's fourth section " Articulifer^," 

 and with neither of the two species of that group does it at 



all accord.
