trom a broad cordate base, the two inner narrow, oblong-lanceolate 
to lanceolate; back minutely pilose, margin conspicuously ciliate. Corolla 
purplish, funnel-shaped, twice as long as the calyx. Capsule globose, 
glabrous, about 3 lin. in diam., 2-celled; seeds densely tomentose.—Vatke

Dr. Capua (in Ann. Istit. Bot. Roma, viii. 227) proposes three varieties under J. 
calycina (cardiosepala, blepharosepala, and neglecta) based on the relative length of 
peduncle and petiole, and petiole and Jamina, 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.
