4. I. trichantha, Oliv. Scandent. Extremities terete, rusty- or cinna- 

 mon-tomentose-pubescent. Leaves ample, membranous, oblong-elliptical or 

 broadly elliptical, cuspidate or shortly acuminate, rounded, sometimes broadly, 

 at the' base, entire, glabrous above, glabrescent or the nerves thinly or ap- 

 pressed-hispid beneath, 6-9 in. long, 2-5 in. broad ; petiole 1-3 lines or 

 leaves subsessile. Flowers densely and rather softly silky-hirsute, crowded 

 in very short simple or slightly branched racemes or spikes ; pedicels very 

 short or 0. Calyx 5-partite ; segments linear-subulate, nearly or quite 

 equalling the petals. Petals barbate within. Anthers ovate-oblong. Ovary 

 hirsute, narrowed into the style. Fruit an ellipsoidal drupe, with a thm 

 softly pubescent skin, about 1 in. long ; endocarp very thin, bony, rather 

 strongly 2-keeled and slightly reticulate. Seed solitary ; embryo often oblique 

 or transverse, shorter than the albumen, with thin foliaceous cotyledons. 

 Testa thinly membranous.

15. IODES, Blume ; Benth. et Hook. f. Gen. PI. i. 355. 



Flowers dioecious, in cymose panicles. Perianth simple or double; " 

 double, the outer minute, 4-5-fid, regular or irregular ; if simple, or the inner 

 if double, 4-5-fid, the lobes valvate in aestivation, sometimes unequal. Male 

 fl. : Stamens as many as perianth-lobes and alternate with them; filaments 

 very short or 0. Anthers 2-celled, dehiscing longitudinally, erect or dorsally 

 recurved. Pistil rudimentary. Female fl. : Stamens 6 or rudimentary. 

 Ovary sessile, usually strigose or hairy, 1-celled, with 2 pendulous ovules ; 

 stigma sessile, fleshy, disciform. The drupe is described as dry, 1-seeded. 

 Embryo more than half as long as the fleshy albumen, with flat foliaceous 

 cotyledons and a short superior radicle.— Scandent shrubs. Leaves opposite 

 or subopposite, entire, membranous. Flowers small, usually in many-flowered 

 pedunculate, irregularly-forking, cymose, axillary panicles, usually hairy or 

 strigillose; the peduncles frequently reduced to cirrhi. 



A small genus, confined to tropical and insular Asia and W. Africa. The African species 

 has precisely the facies of the Indian ones, hut its periauth is simple and the anthers are re- 



nins 



1 and adnate. As, however, the outer perianth, in the Indian species, is probably m- 

 volucral, I do not think a generic separation would be justifiable. 



1. I. africana, Wdw. mss. A weak climber, extending 15-20 ft. or 

 further; extremities at first strigillose or shortly hirsute, at length sometimes 

 glabrescent. Leaves membranous, rather large, elliptical or ovate-elliptical, 

 usually shortly acuminate or cuspidate, broadly rounded subcordate or dis- 

 tinctly cordate and sometimes oblique at base, entire, at length glabrous or 

 nearly so, excepting the usually strigillose midrib impressed above, 3-6 m- 

 long, l£-4 in. broad ; petiole more or less strigillose, £-1 in. Male pani- 

 cles loosely forking from above or below the middle, equalling or exceeding 

 the leaves, thinly strigillose. Perianth simple; lobes at length revolute. 

 Anthers recurved and adnate over the apex of the short filament. Tendrils 

 extra-axillary. Fruit not seen.
