Information
A large herb attaining 6–12 ft. in height. Rootstock a large tuber. Leaves glabrous, all radical; petiole several feet in length, prickly; blade sagittate, very variable in size and general outline; front lobe 5 in. to 1 ft. 5 in. long, 2 1/4 in. to 1 ft. 8 in. broad; basal lobes 4 1/2 in. to 1 ft. 4 1/2 in. long, 1 1/2–10 in. broad, all acute or acuminate. Peduncle overtopping the leaves, stout, prickly. Spathe 9–17 in. long, 3–5 in. broad, lanceolate, acuminate, convolute at the very base only, concave-expanded above, yellow-green, striped with rich dark red-brown. Spadix 2 1/2–7 in. long, 1/2–1 1/4 in. thick, sessile, cylindric or more or less tapering, obtuse, dark violet. Berries 1/2 in. long, 1/4 in. in diam., cuneate-oblong, 2–4-seeded. Seeds 2–3 lin. in diam., roundish, with about 4 series of dentate crests around the circumference, brown; testa moderately thick, crustaceous.

Notes
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 half-developed state of some of the young fruits; and the difference d 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 the same plant at different stages of growth. Barter states on his labels that the plant grows from 8 to 12 ft. high, and that a single spathe and its stem weighs from 10 to 13 pounds. Other collectors give the height as from 6 to 9 ft.
