all cases added in different type after the ' Index Kewensis ' name. Where 

 new species are published in synonymous genera cross-references are given. 



The geographical area comprised is the same as that shown on the map 

 published with the "Enumeration '^ — that is to say, the whole of China proper 

 with Formosa, the Luchu Islands, the Corean Archipelago, Oorea, S. Man- 

 churia, the huge tract of half-desert country between the Nan Shan and the 

 Altai ranges, and the Thibetan provinces of Batang and Litang. Whether 

 the boundary thus indicated is the most natural that can be devised with the 

 greatly increased knowledge of the flora of Asia which we now possess is a 

 matter of doubt, but this would not be the place to attempt to revise it if 

 such revision were desirable. 



The period under notice has seen the commencement of an important 

 descriptive Flora of the eastern watershed of Asia byFinet and Gagnepain *. 

 It comprises nearly the whole of our area as well as the sub-arctic regions to 

 the north-east and the enormous tracts of tropical forest in Cochin China and 

 Siam to the south-west. In it is given for the first time a complete enumera- 

 tion of the species collected by Delavay, Soulie, Farges, Bodinier, Ducloux, 

 and the other great French collectors whose accumulated treasures in the 

 Paris Museum Herbarium are hardly known to the world. 



But perhaps the most encouraging feature of the last few years has been 

 the rapidly growing botanical enterprise of the Japanese. Two elaborate 

 enumerations of the Flora of Formosa have already appeared, while an 

 equidly full account of that of Corea is in progress. 



The completion of Komarov's ' Flora of Manchuria ' fills another gap in 

 our knowledge of the vegetation of the northern boundaries, while further 

 lists of plants sent by German collectors from Shantung and Shensi add to 

 our scanty acquaintance with the Flora of the Northern Provinces of China 

 proper. The Flora of Hupeh, already better known than that of most 

 provinces, receives fresh elucidation through Pampanini's exhaustive list of 

 the collections of Silvestri. 



In South China the chief novelties have been published by L6veill6 from 

 collections made by French Missionaries in the extraordinarily rich mountain- 

 ranges of Kweichau, while the botanical exploration of the South-Eastern 

 Provinces has been continued from the botanical station established by the 

 British Government at Hongkong. 



The energy of the British collector, Mr. Augustine Henry, finds further 

 recognition in this list by the publication of many hundred additional records 

 for the Flora of Yunnan on the authority of his specimens in the Kew 

 Herbarium. Both he and his fellow-countrymen, Messrs. E. H. Wilson and 

 Forrest, have within recent years made enormous collections of splendid 

 material in the wildest and least-explored regions of China, but only a small
