C A JANUS (aboriginal name). Leguminbsse. A 

 tropical shrub, grown for the nutritious peas. One 

 variable species, probably originally from Africa.

 oblong, exstipellate, resinous-punctate beneath: fls. 

 yellow and maroon, pea-like, continuing all through the 

 year, in axillary racemes: pod pea-like, hairy, con- 

 stricted between the many seeds. Much cult, in the 

 tropics for the seeds or pulse, being treated usually as 

 an annual. It varies greatly in stature and in charac- 

 ter of seeds: C. flavus, DC., has yellow fls. and 2-3- 

 seeded pods which are not spotted; C. bicolor, DC., a 

 smaller plant, has red-striped fls., and 4-5-seeded pods 

 which are spotted. See B.M. 6440 and R.H. 1874:190.

 varieties being preferred for human food and some for 

 live-stock; run wild. L. H. B. 



CAJ6PHORA: Blumenbachia. 

 CALABASH: Crescentia. 

 CALABASH GOURD: Lagenaria. 



CALADIUM (origin of name obscure). Aracex. 

 Warmhouse large-leaved plants, grown for the foliage; 

 also employed in summer bedding. 



Herbaceous perennials, arising from large rhizomes 

 or tubers, acaulescent, with usually beautifully marked, 

 long-petioled Ivs.; the secondary nerves oblique to the 

 few spreading primary nerves: peduncles usually soli- 

 tary; spathe with the tube convolute, constricted at the 

 throat, the blade boat -shaped; spadix erect, a little 

 shorter than the spathe, the lower part naked, stipe- 

 like, the staminate part longer than the pistillate; fls. 

 unisexual: fr. a berry, white. A dozen or less species 

 in Trop. S. Amer. Two of the species are immensely 

 variable, and many named horticultural varieties are 

 in the trade. Engler in DC. M^nog. Phan. 2 :452 (1879) ; 

 also F. S. 13.
