fruit. We likewise want to know the direction of the stem 
throughout, of the leaflets, and of the calyx; also the shape of 
the petals and the colour of the styles ; a note of these should be 
made when the specimen is gathered.” 
Willows should have the flower or fruit and the foliage 
taken from the same bush ; or, if otherwise, the fact should be 
stated. 
Cultivated specimens cannot be accepted by the Club, except 
in the case of rare plants, where there is danger of extermina- 
tion ; or in cases in which cultivation throws any additional 
light on the habits of the species. No plant should be sent if by 
so doing there is risk of its destruction or appreciable diminution 
in any locality. 
N.B. — Insects will not attack Herbaria where naphthaline is 
used. 
A complete set of the Club Reports, and a set of the Reports 
of “The Botanical Exchange Club of the British Isles” from 1877 
to the present time, are kept by the Treasurer, and will be lent 
for a limited time to any member who wishes to refer to them.
