Note. — The specialists’ names in the above list ai’e given in alpha- 
betical order when two or more are available for consultation. 
Members may send their specimens of British plants belonging to 
these groups direct to the specialist indicated, together with a stamped 
addressed envelope for reply. If the specimens are required to be re- 
turned, the necessary postage should be forwarded. The addresses of 
the specialists will be found in the List of Members, see pp. 8 to 22. 
It should be understood that the specialist is, not necessarily re- 
pared to name all specimens submitted. In some cases the specialist 
indicated may not yet have attained sufficient knowledge of the group 
he is studying. In other cases the material submitted may be incom- 
plete, lacking adequate data or badly prepared. All the specialists will, 
however, do the best they can to identify plants submitted by members. 
Unless it is reasonably certain that specimens will arrive in good 
fresh condition, they should be sent flat in paper between stiff mill- 
boards to prevent shrivelling. Dried, pressed specimens may be sent 
similarly. Specimens should be carefully labelled with locality, habitat, 
date and any other notes likely to be of use. Whenever possible speci- 
mens should be submitted in duplicate, so that the specialist may retain
