Descr. Plant easily cultivated in earth, but evidently a 

 parasite, like its congeners. Stems woody, covered, as well 

 as the branches 3 (which send out roots from different points,) 

 with greyish bark, rough with the scars of fallen leaves 

 and with scattered black spines. Branches woody, clus- 

 tered, densely covered with fleshy, oblong, nearly cylin- 

 drical joints (leaves?), which are sprinkled with minute 

 dots, and with fascicles of slender black spines. Flowers 

 solitary, from the middle of a joint, large, white, inferior in 

 size only to those of R. grandiflora. Fruit a white Berry, 

 smaller thau that of R. Cassytha. Christy MSS. 



A native, as are most of the Cactus family, of South 

 America, and first described by A. H. Haworth, Esq., who 

 has for many years paid the most devoted attention to the 

 study of succulent plants. That gentleman, however, had 

 not seen the blossoms, which were produced in the stove 

 of our valued friend, W. Christy, Esq. Clapham Road, 

 London, in the month of March, 1831. 



For the drawing of this and the two following species, we 

 are indebted to the accurate pencil of Mr. J. D. Sowerby.
