198 CL. AROIDEE (BROWN). | Cyrtosperma. 
sessile or subsessile, cushion-like. Ovules 2 to several, biseriate on a 
subbasal parietal placenta, amphitropous, becoming much curved. 
Berries smooth, 1- to several-seeded. Seeds rounded in outline, com- 
pressed, crested ; testa crustaceous; albumen fleshy; embryo axile, 
curved,— Herbs with a tuberous or elongated rootstock. Leaves all 
radical, sagittate or hastate, usually prickly on the petioles; primary 
veins rather distant, secondary reticulated. Peduncle solitary, elon- 
gated, usually prickly. Spathe large, coloured, longer than the spadix. 
A small genus of about 7 species, chiefly natives of Malaya and Polynesia, two 
species in Tropical America, and the following one in Africa.

I am quite unable to separate C. Afzelii from C. senegalense ; the globose spadix 
of the former (as figured by Schott) is evidently only the basal part of a spadix 
swollen out into this form by the halt-developed state of some of the young fruits ; 
and the difference noted in the leaves of the two supposed species is not of specific 
value, as the breadth of the front and basal lobes of the leaf varies very much in this 
and allied genera, and is not constant on tke same plant at different stages of growth.
