REGULATIONS OF THE CLUB. 
1. The object of the Botanical Exchange Club is to facilitate the 
exchange of dried specimens of British plants, especially of critical 
Bpeeies and varieties. Anyone wishing to become a member will be 
admitted on payment to the Secretary of an annual subscription of 
Eive Shillings, and on sending a parcel of dried plants in accordance 
with the subsequent rules. He will then be entitled to share in the 
distribution of specimens made in the early part of the year following 
that in which his subscription and parcel were sent. 
2. Specimens sent for distribution must be carefully dried ; must 
not exceed in size half-a-sheet of demy (16 by 10 inches) ; and must 
illustrate the species they represent as completely as possible. Plants 
more than sixteen inches long should be once or twice folded, if by so 
doing the roots can be preserved. (In the Cyperacec^, Gramina, and 
smaller Perns no specimens should be sent without roots, except in the 
case of very rare species, which might be in danger of extermination.) 
Ho plant must be sent that is not included in the list of desiderata for 
the current year, unless it be additional to those enumerated in the 
7th edition of the “London Catalogue of British Plants,” or be from 
an unrecorded station, or be an unrecorded variety. 
3. Each specimen must have a label, bearing the number and name 
of the species as given in the 7th edition of the “ London Catalogue ” ; 
also the locality and county where, and the date when, the specimen 
was collected, and the collector’s name. The label should be affixed 
to the specimen by cutting a transverse slit in the base of the label 
through which the specimen may be pushed. Any facts connected 
with a species which the sender thinks important and suitable for the 
“Beport” should be communicated on a separate piece of paper,
