Report of the Committee, consisting of Mr. Thiselton-Dyer (Secre- 

 tary), Mr. Carruthers, Mr. Ball, Professor Oliver, and Mr. 

 Forbes, appointed for thepurpose of continuing the preparation 

 of a Report on our 2>resent hiotoledge of the Flora of China. 



The further grant made by the Association has assisted the Committee 

 in advancing rapidly with the work, the importance of which is generally 

 acknowledged by botanists. It is based, in the first instance, on the 

 manuscript collections made by Mr. Forbes, as the result of many 

 years' work. These collections have been placed by him, with great 

 liberality, in the hands of the Committee. With these collections are 

 worked up the additional material derived from au examination of the 

 herbaria of Kew and the British Museum (including Dr. Hance's exten- 

 sive Chinese herbarium acquired last year by the trustees of the latter 

 institution). The Committee pay the expense of drawing up the suc- 

 cessive portions of the report from these materials, and also the cost of 

 setting up in type and printing 100 copies of each part. These are dis- 

 tributed to everyone in China whose co-operation there is any likelihood 

 of enlisting in obtaining further collections which would throw light 

 upon its flora. The i-esult has been to excite an amount of interest which 

 could hardly have been anticipated. The Committee have in particular 

 to express the obligations they are under to various members of the 

 Inland China Mission, of the Chinese Imperial Maritime Customs, and of 

 the British Diplomatic Service in China. The Committee have been 

 further aided by grants from the Government Grant Committee of the 

 Royal Society. 



In order to make the result of their labours of permanent usefulness 

 to the scientific world, the Committee have allowed the Linnean Society 

 to print from the type, at its own expense, copies for distribution to its 

 fellows. The Council of the Society further pay the expense of two 

 plates for each part. 



During the past year three more numbers have appeared, and the 

 grant made by the Association about covers the expense of setting these 

 up in type. This brings the Keport down to the beginning of Compositoe,
