Peduncles rather short and thick, mostly 1 -flowered. Sepals oblong-lanceolate, 
acute, nearly equal or the inner ones rather longer. Corolla nearly 2in. long,

Hab.: Islands of the Gulf of Carpentaria, R. Brown. 
The leaves are not unlike those of the slender forms of I. dissecta, to which Choisy refers it, 
but the flowers are totally different. — Benth. 
6. I. dissecta (leaves much divided), Willd. Phytogr. 5, t. 2; Benth. FI. 
Austr. iv. 416. Stems annual, slender, trailing or twining, glabrous as well as 
the foliage. Leaves digitate, with 8, 5 or rarely 7 linear or linear-cuneate 
segments, acute and once or even twice pinnatifid and toothed. Peduncles 
1 or rarely 2-flowered, short, but said to be often longer than the leaves in Indian 
specimens. Sepals ovate or lanceolate, obtuse or shortly acuminate, all nearly 
equal, 2 to 24 lines long, often muricate on the midrib. Corolla white, cam- 
panuiate, about twice as long as the calyx. Anthers oval-oblong, slightly 
twisted when fading. Ovary 3-celled; stigma capitate, 3-lobed. — R. Br. Prod.

J n d. iv. 214 ; F. v. M. Fragm. viii. 17. A tall twiner, having the branches 
petioles and peduncles very hairy or glabrous. Leaves palmate, glabrous or 
nearly so, 2 to 4in. diameter ; leaflets narrowly lanceolate, toothed or pinnatifid ; 
the midrib sometimes hirsute. Peduncles 1 to 2-fid. Sepals nearly lin. long, 
elliptic-oblong, glabrous. Corolla ljin., campanulate, white with purple throat.

8. I. hederacea (Ivy-like), Jacq. Collect, i. 124; lc. i. t. 36; Benth. FI. 
Austr. iv. 416. A tall herbaceous twiner, more or less hirsute, the hairs of the 
stem reflexed. Leaves petiolate, broadly cordate, more or less 3 or 5-lobed, the 
lobes acuminate, the middle one broad or narrow (but not linear), contracted or 
■dilated at the base, the lateral ones shorter and broader, the whole leaf from 14 
to 4in. long. Peduncles short or rarely longer than the petioles, with 2 or 3 
nearly sessile flowers at the end. Bracts linear. Sepals lanceolate, acuminate, 
broader and hispid with long hairs at the base, from 4in. to nearly lin. long. 
Corolla blue or purple, often above 2in. long. Ovary almost always 3-celled.

World, in some places, perhaps, escaped from cultivation. — Benth. 
Seeds said to be a quick and effective cathartic. In India known by the name “ Kala-dana” 
(black seed). The seeds are roasted like coffee, powdered, and a iministered in doses of from 30
