The only complete enumeration o£ the flowering plants of China which has 

 yet appeared began to be issued in this Journal in the year 1886 under the 

 title of " An Enumeration of all the Plants known from China." Its 

 author, Mr. Hemsley, ])ushed forward the work with all possible speed, but 

 the vast amount of material, both in the herbarium and in the library, which 

 had to be dealt with precluded its termination within the space or the time 

 that was originally anticipated. It thus happened that by the time the 

 enumeration was completed in 1904 a very large number of species had been 

 discovered in China which were not to be found in the work. A list, there- 

 fore, prepared by Miss M. Smith, of the records of Chinese flowering plants, 

 published between 1886 and March 1904 and not previously included in the 

 " Enumeration," was issued with the concluding numbers of tbat work. The 

 present compilation is intended to carry on that list up to the end of 1910, 

 and it is planned on similar lines. 



Like Miss Smith's list, it includes references to the places of publication of 

 new species, as well as to records of the discovery in China of plants previ- 

 ously known onl}^ from other countries. With a few exceptions periodicals 

 and other works published before March 1904 have not been exhaustively 

 consulted, and any citations bearing dates previous to that year are supple- 

 mentarv to the list. It has been thought useful to add records of some 

 600 Chinese species, specimens of which have been determined by com- 

 petent botanists, and are preserved in the Kew Herbarium though not 

 previously notified in print. This portion of the list could have been very 

 laroely increased had time and opportunity permitted the consultation of 

 other herbaria, especially those containing such large Chinese collections as 

 are to be found at the British Museum, Paris, Berlin, and St. Petersburg. 



Out of the 3500 citations of flowering plants, about 2000 are references to 

 first publications of species, while some 700 refer to other published additions 

 to the flora. It may be said, therefore, that at the present time new species 

 are being published at the rate of about 300 a year and new records at about 

 100 a year. 



In order to facilitate reference to the list such species as have appeared in 

 the ' Index Kewensis ' are quoted under the names adopted in that work, 

 and if the binomials used in the publications quoted are difierent they are in
