that’ the authorities at Vienna ar© putting aside for me , as far as 
is possible, duplicates of Beiehenbaoh's types. So you a@®, we will 
hare right her© a very helpful nucleus of the critical species that 
have been difficult to understand because of Beiehenbaoh's atrocious 
descriptions and slovenly work. With the tracings made by Sohlecther, 
the photographs and drawings I intend to make at Vienna, this summer, 
v - , . , 
and with the specimens sent to me in exchange, we ought to be aole to 
get on pretty well. 
Vol. 7 of Orchidaceae comes out on April 5th. A copy will be for¬ 
warded to you at once. 
Keep me informed of your needs. It is so simple to get materials 
for you.’ 
A column with anther eto. of Cattleya Decker! in formalin solution 
will be very helpful. 1 have used one of your specimens to illustrate 
this species, but the column needs to be drawn from material that is 
as near natural condition as possible. A lip too, would help, 
Dont forget to study colony formation of orchids in the light of 
mycorrhiza. 
. Would you be interested in Knudson’s recent publication on the 
germination of orchids by means of nutrient solutions. Perhaps you 
would be pleased to try your hand at raising orchids from seeds in your 
garden. 
Yours faithfully,
