APPENDIX. 



too, of Lily-of-t he- Valley, and its tuffets of sky and snow make a wonderful 

 effect as they dot those gaunt aretes of the Min S'an in August, amid the hover- 

 ing velvet butterflies of Delphinium tanguticum. Seed was unluckily not pro- 

 curable ; our hope depends on dormant tubers sent home in the winter, and 

 ere long to be distributed, if all goes well. (It didn't ; this is C. melanochlora.) 



Corydalis Sp. (F 418) is a version of F 113, living on the loess cliffs round 

 Minchow, and differing for the better in having larger flowers of a clear, decisive 

 yellow. There is not yet enough seed to distribute, as almost all the pods were 

 discharged by the time I got back to Minchow. (I take no count here of various 

 other species seen — gawky, dull weeds, lush and ephemeral, of no value except 

 for the Herbarium.) 



Cotoneaster Sp. (F 148). — This is perhaps the most important of all. I 

 have only seen it at one point, in the limestone bottom of the great Siku gorge, 

 where, growing and resting and re-rooting as it goes, in almost pure limestone 

 silt, it ramps perfectly tight and flat along the floor, moulding each boulder 

 in its embrace, and developing a carpet many yards across of refulgently glossy 

 and apparently evergreen rounded foliage, among which glows in September and 

 October a richly-scattered profusion of brilliant scarlet fruits like holly-berries 

 peppered over a lucent ground-willow, with here and there the amber leaves 

 of autumn enhancing the sombre gloss of the carpet's green and the flashing 

 wealth of its bejewelment of berries. These were red and ripe on 28th August ; 

 they were yet larger, redder, and more brilliant still at the latest back-end of 

 October. It is C. Dammeri radicans. In any case it is certainly new to my 

 experience, and should prove a prize of most special preciousness, whether 

 for its own beauty, sheeting a slope, or as covert for delicate Daffodil and 

 Crocus. 



? Cremanthodium Sp. (F 10) has pretty little kidney-shaped leaves, and 

 single golden senecio-stars on stems of 4 to 5 inches in March to April. It 

 abounds in all cool and mossy places of the sub-alpine woodland throughout 

 South Kansu. The seed, however, eluded our notice. 



? Cremanthodium Sp. (F 212) lives in cool moist ledges under limestone 

 cliffs (such as cry aloud for Soldanella) at high elevations in the Min S'an. Its 

 glossy foliage is beautifully crenelate, and it carried several bell-shaped yellow 

 flowers to a 6-inch stem (thereby making its name yet more doubtful) in 

 August. 



? Cremanthodium Sp. (F 239) is, I believe, merely the last, repeated under 

 a new number, unless it be a different and divergent form with more flowers. 

 This cannot yet be distributed. 



Cypripedium Sp. (F 58 and F 85). — This is the great Red Slipper of the 

 sub-alpine slopes and copses all up the Border, peculiarly magnificent near 

 Batanee, on loose soil of a coppice, burnt out some two seasons ago. These 

 Slippers in the relationship of C. ventricosum-speciosum are still very obscure 

 and tangled : whether this be C. Franchetti or C. fasciolalum, or neither or 

 both, I cannot yet pretend to discern. It is a plant of stout and leafy stem, 

 from the upper foliage of which escapes the voluminous baggy blossom, densely
