Dr. Capua (in Ann. Istit. Bot. Roma. viii. 227) proposes three varieties under /. 

 calycina (cardiosepala, blepharosepala,a.\\& neglecta) bused on the relative length of 

 peduncle and petiole, and petiole and lamina, and on the form of the basal lobes of 

 the outer sepals, whether cordate or cordate-sagittate. These varieties are founded 

 on specimens from Eritrea, and it does not seem possible to extend them to a series 

 embracing the whole of Tropical Africa. A larger suite of specimens includes 

 numerous intermediate additional forms, and it seems better to consider them all as 

 mere forms of a somewhat variable species.
