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 Henry Frowde, Oxford University Press, 
Amen Corner, London, E.C. 
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. 
Contributors in America should address their communications to Professor Thaxter, 
Harvard University; and all other contributors to the Editors, at the Clarendon Press, 
Oxford. 
Papers sent in with a view to publication must be type-written and musi conclude with 
a summary of the contents. The illustrative 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 
8JX11J 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.
