 throated sweet-scented long-pedicelled erect or spread- 

 ing fls.: bracts linear-lanceolate, ciliolate: calyx J^in.

 obtuse, yellow-farinose; corolla-tube about twice exceed- 

 ing calyx, the limb divided nearly to base, the lobes

 bracts acuminate from a broad base, frequently den- 

 ticulate, base subsaccate: fls. violet, throat yellow;

XV. CORDIFOLI.E. 



Nearly or quite glabrous, the Ivs. cordate at base 

 and distinctly petioled: corolla funnelform and caps, 

 cylindrical: Himalaya. 



152. Gambeliana, Watt. The buds farinose: Ivs. 

 long-petioled, almost orbicular, about %in. diam., 

 membranaceous, base cordate, dentate; the petiole 



longer than the blade: scape 4}^ in. high, exceeding the 

 Ivs., glabrous, bearing 2-7 fls.: bracts lanceolate, acute: 

 fls. purple; calyx minutely puberulous, campanulate, 

 split below the middle, with lanceolate acute lobes; 

 corolla-tube broadened toward the ringless throat, the 

 limb %-l in. across, with obcordate emarginate lobes.

 Caucasus region. 



153. grandis, Trautv. Plant stout, tall, large-lvd.,

 ceous, wrinkled, ovate or triangular-ovate, base cordate 

 or subcordate, irregularly twice-crenate, very lightly 

 powdery-puberulent below; the petiole narrowly 

 winged, exceeding the blade: scape stout, exceeding the 

 Ivs., bearing a many-fld. umbel: bracts short, lanceo- 

 late-linear, acuminate: fls. borne on filiform pendulous 

 pedicels, pale yellow; calyx campanulate, 5-ribbed, 

 cut one-third of length with triangular acute lobes; 

 corolla-tube cylindrical, with erect oblong-linear, 

 obtuse retuse lobes which have a broad sinus between 

 them; style long-exserted: caps, cylindrical, exceeding 

 the calyx. Caucasus. Gt. 1879:968. 



XVII. TENELL^E. 



Small plants: Ivs. somewhat coriaceous, narrowed to 

 petiole: fls. 1-2 on the scape: caps, globose: Himalaya, 

 China. 



A. Scape practically none. 

 154. muscoides, Hook. f. Plant minute, 

 densely cespitose, very glabrous, not farinose : 

 Ivs. spatulate or ovate-oblong, convex, sessile, 

 apex subtruncate, narrowed toward the base, 

 coarsely toothed toward the top, the broad 

 midrib produced beyond the blade : scape none: 

 bracts small, ovate: fls. sessile, subsolitary, 

 2-bracted; calyx split below the middle, cup- 

 shaped, with triangular acute lobes; corolla- 

 tube slender, cylindrical, the limb about J^in. 

 across, with narrowly obcordate, emarginate 

 lobes. Sikkim-Himalaya. 



AA. Scape about equaling or exceeding the Ivs. 



155. bella, Franch. Plant slender, cespitose, gla- 

 brous: Ivs. from Yi to about 1 in. long, including the 

 petiole, which equals or exceeds the blade, white-fari- 

 nose below, ovate or suborbicular, incise-lobed, the 

 lobes narrow, linear, acute or mucronate, narrowed to a 

 very narrowly winged petiole: scape exceeding the Ivs., 

 1-2-3-fld. : bracts lanceolate, acute, entire or tridentate 

 at the apex: fls. violet-purple; calyx open-campanulate, 

 split to the middle, with deltoid-ovate, acute lobes 

 sometimes tridentate at the apex; corolla-tube cylin- 

 drical, the limb densely white-hairy at the throat, Y-\ 

 in. across, with obovate-cuneate lobes which are bilobu- 

 late below the middle: caps, oblong, small, included in 

 the calyx. S.W.China. Intro. 1908. R.H.S. 39:165. 



156. yunnanensis, Franch. Plant rather small, 

 glabrous: Ivs. J^in. or less long, including the petiole, 

 which is shorter than the blade, obovate-oblong, nar- 

 rowed to the winged petiole, frequently farinose below, 

 crenulate: scape 3-4 times longer than the Ivs., bearing 

 1-2 fls. on pedicels about J^in. long ("in pairs on long 

 slender stalks"): bracts lanceolate, acute: fls. violet- 

 purple; calyx open-campanulate, split to the middle, 

 with deltoid-lanceolate lobes, spreading after flowering 

 and displaying a mealy upper surface; corolla-tube 

 slender, the limb %-l in. across, not very concave, 

 with deeply bilobulate lobes: caps, ovoid, small, 

 included in the calyx. Yunnan, China. Two recent 

 species allied to this are P. kichanensis, and P. umbrella.
