part, with flowers (unknown) springing almost stemless from the crown, 2 or 

 3 often on 1 welded scape. 



Iris Sp. (F 414) is a relation of F 29, abounding on the bare loess in the 

 open valley-bottoms of the Tibetan ranges opposite J6-ni, at some 9,500 to 

 10,000 feet. Its lingering flowers in August were blended of blue and white, 

 and offer good hope that the plant may prove as valuable as it is certainly 

 floriferous. (/. Farreri, Sp. nova.) 



Iris Sp. (F 415) was collected by our Chinese headman as being the same 

 as F 19, which is no more nor less than /. tectorum (abounding in huge masses 

 all over the cool grassy downs between Shi-ho and Foo-er-gai), but the fat and 

 purfled pods he brought seem to me in many ways so distinct from those of 

 I. tectorum that I can but send it out with this caution, though I am unable 

 to suggest what else it might be, especially as it was not collected in the tectorum 

 district. 



Isopyrum grandiflorum (F 96) is so universally abundant in all the cool 

 high-alpine limestone cliffs as to have been, in the end, but too slackly collected 

 this year — especially as its seeds are so minute and its capacious capsules so 

 capricious. Such seed as is distributed will want most careful raising. The 

 species is very beautiful, with cushions of tiny columbine foliage, and big golden- 

 hearted flowers that are not blue, as often said, but of a dense waxen texture, 

 and milk or skim-milk colouring, only rarely deepening to any blue tone. 

 Isopyrum Sp. (F 293) cannot yet be sent out. It occurs in the Monk Mountain 

 district (flower unknown) and differs from /. grcmdiflorum in greener rather 

 larger foliage, and in a distinctly bigger rounder seed. Ipse non vidi : coll. 

 W. Purdom. (/. Farreri beats all, and was introduced in 1915.) 



"Kennedya" Sp. (F 184). — This absurd name I apply for convenience, as 

 nothing else so paints the effect of this plant, with several wiry 10- to 12- 

 inch stems in August springing from the crown, and ejecting on fine peduncles, 

 rich racemes of brilliant blue violet peaflowers from all the upper axils, more 

 brilliant yet for their rich red-purple calyces. It is abundant throughout the 

 alpine grass-lands of Tibet, extending south into the Satanee range. (Yicia 

 anijuga.) 



Leontopodium alpinum, the common type of the European Alps, is an 

 abundant wayside weed over all the loess lands of South Kansu, but there 

 are at least two sub-species or forms of much greater merit from more alpine 

 stations. 



Lloydia Sp. (F 87) (LI alpina) has not yet been sent. It is lovely in all 

 the cold crevices of the higher limestone cliffs, swinging out glassy bubble- 

 bells of pearly white with dark lines, larger and fuller, and much more beauti- 

 fully borne, than in LI. serotina. (Sent in 1915.) 



Lychnis Sp. (F 265) abounds in hedgerows and waysides down the Nan 

 Ho Valley and even across the Black Water, and up to some 7000 feet in the 

 foothills of Thundercrown. It is like a gigantic Ragged Robin of 2 or 3 feet, 

 making a lovely haze of rose amid the pale-blue swathes of Adenophora, with 

 Lilium tigrinum flashing out in blots of orange fire. (Silene Fortunei.)
