J904.} D. Prain— S'owie new Indian Plants. 201 



BootstocJt stout. Leaves 3-5 in. long., terminal lobe 175-3 in. wide, lateral, 

 lobes 6-12- jugate, close-set or distant 15-25 in. long. Floivering stems with 2-3, 

 rarely 4 leaves, reduced to the terminal lobe or with only 1-2 pairs of lateral lobes 

 and solitary, rarely 2, flowers. Flowers '75 in. across. Calyx-\ohea triangular or 

 ovate-acute, enlarging in frnit, finely pubescent and at the ^same time rather spar- 

 ingly hispid, not spreading. Petals rounded' with cuneate base, yellow, distinctly 

 veined, hirsute at least at the base witliin, sometimes sparsely pubescent on both 

 surfaces ; not much exceeding the calyx-lobes in flowers, marcescent but shorter 

 than the calyx-lobes in fruit. Stamens 40-50, filaments hirsute. Carpels hispidly 

 hairy, sessile at the base of the calyx, style glabrous or finely pubescent. Achenes 

 acute at both ends, hispidly hairy. 



Very difEerent'from the common Himalayan Sieversia (Qeum elatum Wall.) and 

 more resembling the Northern Asiatic Geum (Sieversia) rotundifolium liSingsdorE, but 

 with more numerous lateral lobes to the leaves and very different achenes. The 

 species appears to be both local and rare. It has been collected on three occasions 

 but always in Western Sikkim not far from the Nepalese border.

Bootstoch woody, depressed branched. Leaves mostly radical with a few scat- 

 tered cauline, clothed with soft silky hairs; petiole up to 2'5 in. long, slender; leaf- 

 lets ■25-*'75 in. long, cuneate at the base, lobes short, ovate, subacute, nerves obscure ; 

 stipules l^rge, membranous. Flowering sterns "5-5 in. long ; cymes leafy and silky. 

 Flowers pedicelled. Calyx '2 in. long, lobes ovate-lanceolate, acute ; bracteoles 

 lanceolate. Petals suborbicular, not exceeding calyx. Stamens 5. Carpels 30. 

 Achenes ovoid, obtuse, with a few hispid hairs at apex and round the base, recep-

Nearest to and much resembling P. Sibhaldi, but dijffiering markedly in the dark-
