Flora of the Malayan reninsula. 557 



of 5 thin or fleshy processes spreading more or less horizontally from 

 the staminal-column, usually with an erect tubercle on the upper side ; 

 the tips flat or dentate or laciniately cleft. Staminal-column short, 

 depressed ; the anthers minute, ending in a small membranous appen- 

 dage ; pollen-massses 1 in each anther-cell, subquadrate or rounded, 

 sometimes with a thin margin on the inner side, erect, sessile or 

 attached by very short caudicles to the pollen-carriers. Ovary of 



2 carpels, distinct or combined ; style-apex pentagonal, fiat, not 

 exserted beyond the anthers. Fruit of 2 distinct or adherent 

 slender straight follicular mericarps. Seeds thin, winged, comose; the 

 margin recurved. — Disteib. About 10 species, Indian and Malayan. 



Corolla rotate-campanulate ; corona thin, long, entire or laciniate, 



spreading horizontally ; leaves truncate or cordate at base . . 1. H. piperlfolium. 



Corolla ovoid-urceolate ; corona thick, short, much fimbriate, 



more or less erect ; leaves cuneate at base . . . . 2. H. Jimbriatum. 



1. Heteeostemma pipeeifolium. King & Gamble, n. sp. A slender 

 twining shrub ; branchlets pale, terete, slightly channelled when dry, 

 uppermost very minutely puberulous. Leaves membranous when dry, 

 3- to 5-nerved; triangular-ovate, acuminate at apex, broadly truncate at 

 base, sometimes slightly decurrent; both surfaces minutely puberulous, 

 the lower the most; 2-5 to 3 5 in. long, 1-5 to 2'5 in. broad; midrib 

 slender, furnished at the base with 1 or more rather conspicuous glands ; 

 main nerves 4 pairs, the lowest 2 pairs from the base, the first pair very 

 small, the second strong and with the others curving upwards to join 

 near the margin ; reticulations few, obscure, irregular ; petiole slender, 

 twisted, "75 to 2 in. long. Cymes few-flowered, umbellately racemose, 

 on stout -5 to -75 in. long peduncles; the rachis of the raceme thickened, 

 with minute bracts ; pedicels slender, -25 in. long ; buds globose, 

 depressed ; flowers yellow. Calyx-lohes ovate, "05 in. long, ciliate, the 

 margins hyaline ; scales minute. Corolla rotate-campanulate, '3 in. 

 broad, puberulous without, the base short at first, then spreading, 

 divided about half-way down ; lobes triangular, incurved. Corona-pro- 

 cesses spreading, lying flat on the corolla, 1 in. long, linear-lanceolate, 

 entire or variously laciniate, the upper part with a slight rounded pro- 

 tuberance or nearly flat. Staminal-column short ; appendages mem- 

 branous, curved over the style-apex ; pollen-masses erect, waxy, 

 flattened on the inner, curved on the outer edge, sessile on the 

 triangular-elongate pollen-carrier. Carpels distinct ; style-apex thin, 

 flattened, 5-gonal. Follicles slender, long-acuminate, recurved to about 



3 right angles, 4 to 5 in. long, -15 to "2 in. broad; pericarp thin, smooth. 

 Seeds ovate-oblong, very thin, with broad thin margins ; apex bearing a 

 •75 in. long white silky coma ; testa very thin, brown.
