1, CABDIOSPERMUM, Linn. 



Flowers polygamous. Sepals 4, broadly iml)ricate, the 3 outer ones 

 sinall. Petals 4, 2 larger with a large scale, 2 smaller with a crestt;d scale. 

 L'lSK oue-sidcd, almost reduced to 2 promiueut glands op[)ositc the lower 

 petals. Stamens 8, oblique. Ovary cxccntrical, 3-celled, ^vith 1 ovule in 

 each cell ; style very short, with 3 stigmatic lobes. Capsule vesicular, mem- 

 branous, more or less 3-comercd, 3-celled, opening loculicidally. Seeds 

 globose, witlx a thick funiclc or small aril ; testa crustaccous ; cotyledons 

 '•ygc, transversely folded. — Herbs or uiidershrubs, mostly climbing. Leaves 

 dissected. Flowers few, small, on long axillaiy peduncles, which usually bear 

 « tendril under the panicle. 



A small genns, chiefly American, of which 2 species arc also spread ov 

 ^^'thin the tropics, and a third is perhaps confined to the Old World. The Australian spe- 

 cies IS one of those most widely diffused in both worlds. 



1* C. Halicacabum, Lhin. ; DC. Frod. i, 601. A straggling or 

 somcwliat climbing annual or perhaps perennial, attaining several feet in 

 length, glabrous or sliglitly pubescent. Leaf-segments usually twice ternate, 

 ^^'ate or ovate-lanceolate, coarsely toothed or lobed, the upper leaves smaller, 

 iiavrower and less divided. Peduncles 2 to 3 in. long, bearing a double or 

 treble short recurved tendril under the small panicle, which is often reduced 

 to an umbel of few small white flowers. Capsules flat on the top, usually 

 pubescent.— A. Gray, Gen. 111. t. 181 ; Wight, le. t. 508.

I he species is common in most tropical regions. The Australian specimens belong either 

 to the variety with fruits scarcely f in. diameter, often considered as a distinct species (C. mi- 

 crocarpum, H. B. and K.), or are iuteraicdiatc between that and thetvpi<.-id form, wilh fruits 

 above 1 in. diameter.
