forth golden-yellow Poppies over a long period, in sprays of some 8 to 12 

 inches high. 



Disporon pullum (F 60) is a singularly beautiful woodland treasure, 

 first seen on the Feng S'an Ling, and thence abounding sporadically throughout 

 the lower alpine forests of the Satanee-Gahoba district. It has all the branching 

 habit of a Streptopus, and grows about 10 to 12 inches high, hanging out 

 clusters of the most exquisite waxy Lapageria-blossoms, with golden anthers. 

 These ring out their chimes in mid-May, and the growth afterwards develops 

 and expands a little, replacing the flowers with bloomy black-blue berries in 

 October. Obviously the treatment of Streptopus and Polygonatum ought 

 handsomely to satisfy a beauty so nearly related, and delighting in the same 

 rich, cool, woodland conditions. Its effect is, indeed, more that of Uvularia ; 

 most unluckily, though the seed of this lovely plant was all good, none of it, 

 so far as I know, germinated. 



Farreria Sp. (F 19a), {novum genus, Balf. fil.), or Wikstroemia Farreri (Balf. 

 fil.), is a singularly lovely little ground Daphne, with clusters of bright citron- 

 yellow flowers, twice met with on the high, bare loess downs of South Kansu, 

 April 18 and April 20. Unfortunately seed could not be got, and roots were un- 

 negotiable. There is another species, F 71, brilliantly golden, but of quite in- 

 ferior merit, which abounds in rocks and dry coarse alpine turf on the Satanee 

 ranges, between 7500 and 9000 feet ; this also appears so shy in seed that 

 none could be found, though occasionally, as on burnt-out ribs of rock, its 

 evidence was plain, in small compact young plants. 



Gentiana Sp. (F 25) is abundant all over South Kansu and the Tibetan 

 Border, ascending to 8000 feet, and luxuriating in any open, sunny position 

 wet or dry, but especially profuse in river-shingles and fallow fields. In its 

 second year the seedling forms a glossy crown, like that of some stout G. verna, 

 and in the third this becomes from March to November an endless display of bright 

 azure stars on long tubes. The ovary matures at the tip of an exaggeratedly 

 protruded style, as the flower withers ; its two lips quickly gape, and the seed 

 is gone. This fashion seems common among the better Gentians of the 

 Border. 



Gentiana Sp. (F 217). — This number covers a most beautiful Gentian, very 

 abundant in the higher alpine turf of the Min S'an, where it literally turns 

 the turf to a sea of blue with the profusion of its pale clear water-blue trumpets, 

 most delicately lined with darkness on their outside, and poising each singly at 

 the end of the whorled-foliaged stems that spring in such masses from the crown. 

 The species either varies or includes two species. Seed sent as F 217 was for 

 the most part collected on Thundercrown ; the Min S'an type is to all intents 

 and purposes the same, but differs conspicuously in having a very much larger 

 ovary. This last has also been sent as F 332. Seed is borne as in the last, 

 and the heyday of the bloom is in August. {G. hexaphylla : a success.) 



Gentiana Sp. (F 220).— This is quite like G. frigida, but taller and in 

 every way better developed, growing about 8 inches high, with 6 or 8 large 

 long straw-coloured trumpets in August. It is general all along the line of
