May 1922. 
The late Cedric Bucknall, Mus.Bac., Oxon, was not a 
member of this Club; but his valued help on Euphrasia, Sym- 
phytum, and other genera was so freely given to us that we 
should like to place on record a sense of the loss we, together 
with students of Systematic Botany in general, have sustained 
through his sudden death on Dec. 12th, 1921. — Hon. Sec. 
RULES. 
1. The objects of the Watson Botanical Exchange Club 
are to promote more intercourse between British botanists, to 
facilitate the exchange of dried specimens, and to study, as much 
as possible, British plants belonging to the critical genera. 
2. The subscription is 10s. 6 d. a year, and is due on Jan. 1st. 
3. a. Members may send to the Distributor for the time 
being, before December 31st each year, parcels of plants for dis- 
tribution, and they will receive in return plants in proportion to 
the number and quality of those sent. 
b. Each plant or sheet of plants must bear a label, preferably 
with the heading and outline printed, giving the name, place 
where collected, collector’s name, and date. The labels should 
not be attached to the specimens nor to the sheets. A series of 
duplicate labels should be sent for the Report; or preferably the 
data, in the order to be printed, may be written on sheets of 
paper, with a line left between each plant. 
c. At least six sheets of each plant should be sent. Single 
specimens are for record only, not for distribution. 
d. It is particularly requested that good specimens should 
be sent. Scraps are not of the slightest use.
