Very often dried material is wholly inadequate when we attempt 
to differentiate between species that the field botanist comes to 
recognise with ©as®. But, in my opinion, we should not allow color 
to swamp the deeper significance of structure. Similar structure 
than 
is more dependable, it scorns to mo,/different color patterns, and 
the variety and subspecies should be given more attention than 
some of us think they deserve. By this I mean that tho multipli¬ 
cation of species should be attempted only after long and conscient4 
ious study of the stability of characters. Ponding admission to 
specific rank the variety is a good starting point for some of 
those polymorphic plants that need to be studied intensively be¬ 
fore they are in a way to be understood.

Formalin material of Gongora would be very acceptable for 
drawing as well as for study. ' 
Just as soon as/can estimate the amount of space your collects 
ion will take up I will send you drawings of a steel case I intend 
to have made. 
Labels will be sent to you shortly 
If there is anything ©Ise that you need, please keep me in¬

Yours with all good wishes.
