NOTICE TO SUBSCRIBERS. 
The subscription-price of each volume is thirty shillings, payable in advance : the 
Parts, four in number, are supplied as they appear, post free to subscribers in the United 
Kingdom, and with a charge of is. 6d. per annum for postage to subscribers residing 
abroad. The price of individual Parts is fixed at a higher rate. Intending subscribers 
should send their names, with subscription, to Humphrey Milford, Oxford University Press, 
Amen Corner, London, E.C. 4. 
As the earlier volumes of the Annals of Botany are becoming- scarce, Vol. I will 
only be sold as part of a complete set ; and Parts will not as a rule be sold separately, 
after the publication of the volume to which they belong. A few extra copies of particular 
Parts at present remain on hand, for which special application must be made to the 
Editors, Clarendon Press, Oxford. 
NOTICE TO CONTRIBUTORS. 
English contributors should address their papers to Prof. J. B. Farmer, Imperial 
College of Science and Technology, South Kensington, S.W. 7 ; and contributors 
in America to Prof. R. Thaxter, Harvard University, Cambridge, Mass. 
Papers sent in with a view to publication must be type-written and must conclude with 
a summary of the contents. In view of the increasing numbers of manuscripts submitted 
and the inevitable limitations of space, the Editors desire to impress upon contributors 
the importance of conciseness in the treatment of their subject-matter. Whilst they are 
not prepared at present to draw a hard and fast line, the Editors suggest that the longer 
papers should not exceed 12,000 words. Contributors will receive one proof in page, but 
it is assumed that all but verbal corrections have been made in the original manuscript; . 
an allowance at the rate of ten shillings per sheet of sixteen pages is made for alterations in 
the proof (printers’ errors excepted), and contributors will be responsible for any excess. 
Illustrations. These where possible should be suitable for reproduction as line- 
blocks in the text. Where lithographic or collotype plates are required the figures should 
be planned so as to fill properly a 4to or an 8vo plate. The maximum space available 
for figures in a 4to plate is 8Jx nj inches, in an 8vo plate 8^x5^ inches. Attention 
to this will conduce to the rapid publication of papers if accepted. 
Each contributor to the Annals of Botany is entitled to receive gratis one hundred 
separate copies of his paper, and may purchase additional copies if he informs the Editors of 
his wishes in this respect when he returns corrected proofs. The price of these additional 
copies will depend upon the amount of text and the number of plates in the paper.
