355 Commonwealth Avenue, Boston, Mass. April 14, 1922. 
My dear Dr. Schleohter: 
The roll of tracings arrived by mail 
in perfect condition and proved to b® above expectations. What 
a mountain of work they represent! I cannot thank you enough 
for your kindness. The tracings of types from your own herb¬ 
arium are beautiful productions and are most helpful. I hope 
you can have more of them prepared for me so that all of your 
Central American typSs will soon be represented her®. 
The December number of Fedde's Repert- 
oriura has just arrived. I note that Dr. Eraenzlin has given us 
some new species to digest. I wish it were possible to obtain 
tracings of the Philippine novelties. In working up one of the 
Philippine Bulbophyllums he states that he has searched the 
literature up to 19121 I believe I have published thirty or 
more species of this genus from the Philippines since that 
date. Kraenzlin's Oncidiinae has also come to hand. Although 
I have not yet been aole to study this work, I find that it 
fails to conform with my views as to the species of Equitantia 
from the West Indies. 
, What is Habenaria avioulalgSohltr? H. dip 
leura and H. quinquefila Sohltr and H. spithamea are still 
missing from the list of tracings. 
when you write again let me know what 
the conditions are in Berlin for American travellers. I am 
planning to spend about two weeks at JCew. Then I may devote a 
week to Paris. This would bring me to Berlin at about the end 
of July. 
Yours sincerely^ ^
