The genus Cistanclie, regarded by most authors as a 

 section of Phelipdea, is retained in the M Genera Plantarum," 

 because of the peculiar habit of the species, the sub-equal, 

 obtuse lobes of the calyx, and the dense inflorescence. It 

 consists of about a dozen species inhabiting the Mediter- 

 ranean region and the Orient, from Portugal and Marocco 

 eastward to the Punjab. C. violacea is a rather common 

 plant in North Africa, from Marocco through Algeria to 

 Tunis, growing both on the sea-shore and in the saline 

 districts of the interior. The plant figured here was sent 

 to Kew, in March of the present year, to be named by 

 Mrs. R. W. Dent, of Flass, Crosby Ravens worth, Shap, 

 Westmoreland, who received it from a friend staying at 

 Biskra, Algeria, who found it "in the desert growing 

 straight out of the sand, where it is brackish." The 

 plant reached Kew in fairly good condition, except that 

 August 1st, 1893.
