COLLECTION MADE IN WESTERN CHINA. 301 



herbaceous genera I find that the known Chinese species of 

 Pedicular is number about 100, Gentiana is represented by 

 65 species, Senecio, Saussurea, and Primula each by 50, and 

 Lysimachia by 40. Taking in the same manner half-a-dozen 

 woody genera, Rhododendron has 70 species, Rubus 50, Lonicera 

 40, Viburnum and Vitis 30 each, and Fuonymus 20. 



I may add that a very large proportion of these species have 

 been collected in the provinces of Hupeh, Szechuen, and Yun- 

 nan, and further that only certain districts of these provinces 

 have been fully explored. 



Many other interesting facts have come to light in this con- 

 nection, but I must reserve them for a more detailed examination 

 of the flora. 



I am indebted to Mr. Eolfe for the descriptions of the Orchids, 

 to Mr. N. E. Brown for those of the Aroids, and to Mr. J. G. 

 Baker for that of the Adiantum.

* As all of Mr. Pratt's plants have the same general label, namely, " Western 

 Szechuen and Tibetan Frontier: chiefly near Tachienlu at DOCK) to 13,500 feet," 

 it is unnecessary to cite any more than the number.
