I have seen no authenticated specimen of this species, and the determinations 

 are made with some reserve. The species is very near C. planiflora, differing only 

 in the longer, more acute corolla-lobes. — A. B. R. 



2. C. planiflora, Ten. Fl. Nap. iii. 250. Stems very slender,

 5, ovate, obtuse to subacute, about as long as the tube. Corolla slightly 

 exceeding the calyx, globose-urceolate ; lobes 5, ovate, obtuse, pale 

 pink or whitish, spreading, barely as long as the tube; scales broad, 

 shortly fimbriate above. Stamens 5, shorter than the lobes. Styles
