The date of part 4 is a little uncertain : following Kew Journ. 

 Bot. it is here given as 1853, but A. Gray gave 1854 as the date, and 

 it was not reviewed in the Gardeners' Chronicle until April 22, 1854. 

 Another doubtful point is what pages were comprised in parts 4 and 5 

 respectively. We know that part 4 began at p. 121, and part 5 

 ended with p. 200, and it is here assumed that each part contained 

 40 pages, part 4 including pp. 121-160 and part 5 pp. 161-200. On 

 the other hand, Asa Gray stated that part 4 included about half of 

 the Composites, which suggests that it may have stopped at p. 152. 



According to A. Gray and the Gardeners' 1 Chronicle, 14 pages 

 (7 leaves) were reprinted to correct errors and give additional infor- 

 mation, and were issued with part 10 in 1857. These included 

 pp. 253-4, 279-80, and 345-6 ; the four remaining leaves have not 

 been traced. Cancel-page 254 is headed " Further Additions and 

 Corrections, June 8, 1857 " ; cancel-page 280 includes a new species 

 Tephrosia madrensis Seem., which appeared on the original page as 

 Galactia- marginalis Benth. ; and Mr. Britten points out that the 

 leaf 345-6 in the Natural History Museum copy is fixed to the 

 remains of one which previously existed. The writer is indebted to 

 his colleague, Mr. S. A. Skan, for some important references, without 

 which the preceding account could not have been completed.

In his preface to the work, Seemann acknowledges the help of 

 various botanists " whose labours will confer a lasting value upon it 

 however small the merit that may be ultimately assigned to the
