NEW AND KARL MALAYAN PLANTS. 25 



from Penang is the same. V. polythyrsa, Miq. a much more 

 slender plant does not occur in the Malay Peninsula at all; 

 nor does V. thyrsiflora, Miq. which resembles V. polystacliya, 

 hut is very thickly tomentose instead of being nearly glabrous 

 heneath the leaves. All the specimens put under these two 

 species quoted by King, which I have seen, are V. polystachya, 

 Wall. 



V. capillaris, n. sp. 



Slender vine; stem arachnoid hairy. Leaves compound, 

 petiole 1.75 long, base thickened and red hairy, leaflets mem- 

 branous, central one elliptic lanceolate rather abruptly nar- 

 rowed to a broad or acute mueronate point 2.5 in. long, 1 in. 

 wide, petiolule short red hairy, lateral petiolules .3 in. long, 

 blade hairy trifoliate, uppermost leaflet biggest, lanceolate acu- 

 minate, laterals oblique narrowed to base, sparsely toothed on 

 the outer edge, nerves 3 — 4 pairs, slender, hairy beneath, .5 — 

 1.5 in. long, .4 — .9 in. wide. Peduncle 4: in. long, slender 

 pubescent, panicle 2. 75 in. long, branches .5 in. long or less, all 

 pubescent, lower ones branched again. Flowers distichous, 

 .05 in. sessile. Calyx cup-shaped, obscurely 4-toothed, gla- 

 brous. Petals 4, oblong. Ovary conic, style conic, stout. 



Borxeo. Sarawak (Beccari, 748). 



Xearest to V. polythyrsa, Miq. but much more slender, 

 much less hairy, leaves thinner, leaflets fewer-nerved and 

 toothed and more oblique. 



V. pterisanthella, n. sp. 



A slender vine nearly completely glabrous except the in- 

 florescence. Leaves trifoliate, membranous, petiole 1.2 — 2 in. 

 long, leaflets thin, elliptic acuminate nearly entire with about 

 three short obscure teeth towards the apex, narrowed at the 

 base, median elliptic lanceolate, laterals with an oblique 

 rounded base, nerves very fine and inconspicuous, G pairs, 

 median 2.75 — 4 in. long, 1.2 — 2 in. wide; petiolule .4 — .6 in. 

 long ; laterals smaller ; petiolule .2, a few red hairs at the base 

 of the petiolules. Inflorescence very slender, 3.5 in. long, 

 peduncle nearly 3, bearing a slender tendril 1.5 in. long and 

 sometimes twining itself. Spikes few, about 7, .4 in. long, 

 pubescent, rhachis at base flattened broadly and narrowed to 

 tip. Flowers distichous, pubescent, .05 in. long, sessile. Calyx 

 lobes ovate, subacute. Petals 4, much larger, puberulous out- 

 side. Stamens 4, anthers large, oblong, filaments short. Ovary 

 subglobose with a thick conic style, glabrous. 



Bokneo. Sarawak; Siul (Ridley). 



I collected, this very curious vine in September 1905 in 

 the forests on the Siul Hill near Kuching. It seems most 

 nearly allied to V. capillaris, Kidl., but is very peculiar in the 



R. A. Soc, No. 75, 1917.
