Trollius pulcher Making, sp. nov. 



A glabrous perennial, about 2-6 decim. high, erect, with 

 wiry fibres of the basal portion of old stems and petioles at 

 the base ; roots tufted, fibrous, stout-filiform, with very short 

 rootlets, nigrescent when dried. Stems" few ceespitose, mostly 

 simple, terete, often stout, usually 3- rarely 2- or 4-foliatc, 

 uniflorous rarely biflorous at the top, provided with a few 

 membranaceous sheaths at the base, attaining 9 mm. across. 

 Leaves flaccidly herbaceous, reniform in outline, attaining 

 about 12cm. long, 19 cm. broad, 3-sected into 3 primary seg- 

 ments, thin; segments sessile, cuneate at the base, inciso-dentate 

 with the sharp subulate teeth; lateral segments broader, deeply 



2- parted ; 2nd segments : outer one 2-parted ; inner one 



3— cleft ; primary middle segment elliptical, 3-cleft ; veins loose- 

 ly anastomotic with longitudinal coarse areola, conspicuous 

 beneath ; radical leaves few, long-petiolate, shorter than the 

 stem ; cauline leaves shortly petiolate in the lowest one, but 

 sessile and smaller in size in the superior 2 rarely 1 or 3, the 

 uppermost one smallest and often simpler in form ; petiole 

 shathing towards the base. Flower golden yellow, sub- 

 spasroidal, 3-5J mm. across, erect, rather shorth^ peduncled. 

 Sepals many, 14-15 in number, concave, subconnivent, im- 

 bricated and assumed a subglobular form collectively, sessile, 

 orbicular and reflexo-ascending and attaining about 2^ cm. 

 long and wide in the outer ones, but narrower in the inner 

 ones, entire but often denticulate towards the rounded apex, 

 closely and numerously veined, membranaceous, deciduous. 

 Petals small, several (about 5-7), shorter than stamens, erect, 

 linear-spathulate, obtuse at the apex, shortly unguiculate, 

 entire, longitudinally several-veined, with a nectariferous feveole 

 at the base of the lamina, about 8^-10 mm. long. Stamens 

 numerous, mainly exceeding the pistils, 7-12 mm. long ; 

 filament filiform, longer than the anthers; anther oblong- 

 linear, 21 mm. long. Pistils numerous, densely placed, about 

 41-7 ram. long, sessile, erect in the central ones but ascending- 

 erect in the outer ones ; overy subulato-linear, gradually at- 

 tenuated into the style above, arcuate in the outer ones ; style
