in upper half, the inner face hollowed out in the lower half (fig. 168, f), the 

 lower edge of the thickened portion forming in front view a two-lobed lip' (fig. 

 168, g) : whitish in the lower part, crimson above, especially on the recurved tip • 

 smooth or finely scabrid on the back, J inch long (measured along the curve)' 

 tV inch broad. Stamens 5, erect, slightly exserted owing to the petals being re- 

 curved, I inch long, filaments stout, tapered, contracted and abruptly bent inwards 

 at the apex, white ; anthers yellow on face, crimson on back. Scales quadrate 

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

 upper part, shghtly shorter than the stamens, erect, the inner edge straight or 

 neariy so, the outer edge in its lower half parallel to the inner, or convex, in its 

 upper half contracted, often rather abruptly, into the tapering 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 minor 

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

 lished (which were mostly prepared from dried specimens), and in 

 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, b, 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. Forresti 

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

 and wai.yunnanense Hamet, a hairy form, of which I am able to amplify 

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

 from Maire's seed. 



Another distinct form, deservmg of varietal rank, appeared in 

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

 •been described as var. densirosulatum. 



Var. yunnanense Hamet (fig. 169).
