e. No plants must be sent which are not included in the 
“List of Desiderata” for the current year (when published), 
unless new to the County or Vice-County in which gathered, or 
additional to those enumerated in the last edition of the London 
Catalogue. 
/. Each member must let the Distributor have a London 
Catalogue of British Plants with a horizontal stroke (thus — ) 
before each of his desiderata, which may be cancelled by a per- 
pendicular stroke (thus + ) when the plant is no longer wanted. 
These Catalogues should accompany the parcels. They will be 
returned in the return parcels. No MS. list will be accepted. 
g. The plants in the parcels must be dried so that they can 
be mounted for the herbarium on sheets of paper 16 by 10 
inches, and should be arranged in the order in which they are 
printed in the 10th ed. of the London Catalogue. Specimens of 
the same species should be put on separate sheets in one cover, 
each sheet being accompanied by one label, with the name of the 
genus and species, and its number in the London Catalogue, 
written on the outside of the cover. These covers should all be of 
uniform size; from 16 to 17 by 10 to 11 inches is recommended. 
h. The covers should be made up in a parcel enclosed by two 
stiff cardboards measuring about 17 by 11 inches. Each board 
should bear the owner’s name, and it will be used in the return 
parcel. 
4. Members will very much increase the scope and work of 
the Club if they will send for examination any Batrachian 
Ranunculi, Rosse, Rubi, Callitriche, Hieracia, Menthae, Salices, 
Naiadacese, Junci, Carices, Characese, etc., the study of critical 
species being one of the principal aims of the Club. One speci- 
men of each will, if possible, be returned to the owner after 
examination. 
In the case of Hieracium and Erodium the colour of the style 
and stigma should be stated on the label. 
The following quotation from Prof. Babington’s “British 
Rubi ” will show what a perfectly diagnosable specimen of a fruti- 
cose Rubus should consist of : “ To judge properly of a bramble 
from a preserved specimen we require a piece of the middle of 
the stem with more than one leaf ; the base and tip of the stem 
are also desirable. Likewise a piece of the old stem with the 
flowering shoot attached to it; the panicle with flowers, and the
