in upper half, the inner face hollowed out in the lower half (^8- ^^S /), the 

 lower edge of the thickened portion forming m front view a two-lobed hp (fig. 

 168%) whitish in the lower part, crimson above, especially on the recurved tip 

 smootiio7 finely scabrid on the back, i inch long (measured along the curve), 

 ^inch broad. Stamens 5. erect, sUghtly exserted owing to the petals being re- 

 Srved i inch long, filaments stout, tapered, contracted and abruptly bent inwards 

 at 4e apex! white ; anthers yellow on face, crimson on back. 5.a^.. quadrate 

 curved emarginate pink, orange, or whitish. Carpels pale green dotted red m 

 upper pS.sUghtly shorter thin the stamens, erect, the inner edge straight or 

 nearly so. the outer edge in its lower half parallel to the inner, or convex, m its 

 upper half contracted, often rather abruptly, into the tapenng style (fig. 168. k), 

 which is at first erect, later divergent ; stigmas capitellate. 



Flowers September-October. Not hardy. 

 Habitat.— Himalayan region, W. China. 



The above description is taken from a good series of plants grown 

 at Kew, Glasnevin, and my own garden, from seed sent by Rev. E. E. 

 Maire from Tong-tchouan, Yunnan, in 1915. It differs in some mmor 

 respects from the descriptions and figures of the plant hitherto pub- 

 lished (which were mostly prepared from dried specunens). and m 

 other respects it supplements them. It is clear that we have to deal 

 here with a polymorphic species, and identity of description need not 

 be expected. On fig. 168, a. h, c represent the first-year rosette and 

 one of its leaves, in plan and section, of what may be taken as type ; 

 d, the rosette and leaf of a narrow-leaved form. 



Two varieties have been previously described— var. Forresh 

 Hamet with very broad ovate-suborbicular leaves, mostly opposite, 

 and vds.yunnanense Hamet, a hairy form, of which I am able to ampUfy 

 the description, as it was well represented among the plants raised 

 from Maire's seed. 



Another distinct form, deserving of varietal rank, appeared m 

 some numbers among the plants grown from Maire's seed, and has 

 been described as var. densirosulatum. 



Var. yunnanense Hamet (fig. 169).

Rosettes much smaller than in type, i to ij inch across, lax. Leaves not 

 glaucous green or brown (owing to dense purple mottling on the green surface), 

 with dense, short, white pubescence (especially on the young leaves) over both 

 surfaces or at least in the upper part and on the edges ; hairs linear-deltoid. 

 patent or slightly deflexed ; leaves \ to i inch long, f^ to ^V wide, extremely 

 thick (up to nearly \ inch), oblanceolate, spathulate, acute or acuminate, convex 

 on face, very convex on back, rounded on edges. Stem 2 to 4 inches long, 

 hairy, densely leafy, the leaves oblanceolate, pubescent. Inflorescence small, 

 (i inch across), rather dense, flattish, of few branches ; branches and pedicels 

 very short, shortly pubescent or papillose ; bracts few, obovate-lanceolate, 

 shortly pubescent or papillose. Flowers rather larger than in the type, up to 

 i inch long. Calyx narrower in proportion to its length, papillose. Petals 

 papillose on back, oblong-lanceolate (not broadly oblong), devoid of thicken- 

 ing on the face, more erect at base (so that the flower is narrower), and less 

 reflexed at apex, making the whole petal much straighter and the flower longer 

 (fig. 169, c). Papillae of bracts, inflorescent branches, sepals, and petals conical. 

 Stamens not abruptly bent at apex, anthers red. Carpels lanceolate.
