Flora of the Malayan Peninsula. 149 



rather broad in bad, '2 to '25 in. (sometimes '4 in.) long, the pedicels 

 varying in length, the ultimate umbellales with rather large, broad, blunt 

 bracteoles at the base. Calyx under '] in. long, campanulate, the lobes 

 6, broad, blunt, thick, spreading. Corolla several times longer than the 

 calyx, broadly ovate and angled in bud ; the 5 lobes ovate, acute, boldly 

 1-nerved, longer than the cone of anthers, spreading or reflexed. 

 Anthers almost sessile, narrowly linear-lanceolate, the connectival margin 

 narrow and the apicular appendage short. Capsules somewhat fleshy, 

 hemispheric, "1 in. in diam., crowned by the small calyx, 2-celled, the 

 dehiscence circumscissile. 



Perak : at elevation of from 2,500 to 4,500 feet ; ScortecMni 282, 

 384; TFra2/410. 



VAR. glabra. Leaves glabrous on both surfaces. 



Perak: ScortecMni 412, 1204; Wray 2814<; King's Collector 5064; 

 Ctirtis 3146. 



This differs from A. imifolium in its corolla being broadly ovate in bud and 

 having ovate, boldly 1-nerved lobes, in having its anthers almost sessile, with very 

 long cells and short apical appendages. This has also larger leaves with more nerves 

 which are sometimes hairy ; its stems are also shorter and stouter. 



11. Argostemma spinulosum, Clarke in Hook. fil. Fl. Br. Ind. III. 

 46. Stem only 3 to 8 inches long, nearly as thick as a goose-quill, 

 decumbent and rooting at the base, obscurely 4-angled ; with a few 

 deciduous flexuose hairs. Leaves crowded, subcoriaceous, very unequal, 

 the larger of each pair oblong-oblanceolate, acute or acuminate, slightly 

 narrowed from above the middle to the somewhat unequally-sided base; 

 upper surface olivaceous, with a few thick, scattered hairs chiefly on the 

 broad depressed midrib and near the edges, otherwise glabrous; the 

 lower pale brown with many thinner hairs on the prominently raised 

 broad midrib and on the nerves, and a few on the interspaces ; main- 

 nerves lO to 14 pairs, curved, spreading, distinct on the lower surface, 

 faint on the upper ; length 25 to 5 in.; breadth 1 to 1*75 in.; petiole 

 •2 to '5 in. Smaller leaf lanceolate to oblong, sessile, 3- to 5-nerved, '5 

 to "75 in. long. Stipules like the smaller leaves but shorter and with 

 only one nerve. Umbels terminal, simple or compound, solitary or 

 several, all on long peduncles shorter than the leaves, sometimes united 

 at their bases ; succulent, few-flowered, glabrous, 1*5 to 2 in. long ; umbels 

 or umbellules 3- or 4-flowered. Flowers 35 to '4 in. long, on slender 

 pedicels of about the same length, with lanceolate scarious bracteoles at 

 their bases, glabrous. Calyx campanulate ; the limb with 5 triangular 

 acute spreading lobes shorter than the tube. Corolla about twice as 

 long as the calyx ; its lobes broadly lanceolate, acuminate, shorter than 

 the erect staminal cone: filaments short, curved; anthers linear-oblong,
