198 CL. AROiDE.E (brown). [Ci/rtospetviui . 



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 ; alburaen 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, 



1. C. senegalense, Enyl. in DC. Monogr. Phan. \\. 270. A large 

 herb attaining (J-12 ft. in height. Rootstock a large tuber. Leaves 

 glabrous, all radical ; petiole several feet in length, prickly ; blade 

 sagittate, very vari9,ble in size and general outline ; front lobe 5 in. to 

 1 ft. 5 in. long, 2\ in. to 1 ft. 8 in. broad ; basal lobes 4^ in. to 1 ft. 4 J in. 

 long, 1|-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-ex- 

 panded above, yellow-green, striped with rich dark red-brown. Spadix 

 2J-7 in. long, ^-1| in. thick, sessile, cylindric or more or less tapering, 

 obtuse, dark violet. Berries J in. long, \ in. in diam., cuneate-oblong, 

 2-4-seeded. Seeds 2-3 lin. in diam., roundish, with about 4 series of den- 

 tate crests around the circumference, brown ; testa moderately thick, 

 crustaceous. — Engl. & Prantl, Pflanzenfam. ii. iii. 123 ; Mitth. Deutsch.

I am quite unable to separate C. Afzelii from C. senegalense ; the globose spadix 

 of the former (as figured by Scltott) 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 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 the same plant at different stages of growth.
