My dear Dr, Sohleohter: 
Your good and very weloorae letter of 
August thirty-first reached me this morning, I was delighetd 
to learn from it that you are still at work and that you have 
been busy with useful publications on the Orchidaceae. X shall 
be most interested to receive oonorete evidence of your indus¬ 
try. not only for its own sake but for the help it will bo to 
mi in my investigations, 
I am pleased to learn that you were 
able to publish some of the Chinese species and to know that 
you were kind enough to include me in the authorship. Of course 
it is a pleasure to be associated wijrh you in the naming of 
new orchids although I had no right to expect that you would 
give me credit for taxonomic work in which I only had a hoped 
for part. 
Sow, as to the Adenostylis. I published 
this under the name A, Wonzelii in the fifth volume of my Oraid- 
aoeae. At the time I worked on this species I had very serious 
doubts as to its generic position. You will remember that I 
asked your opinion about this and that you reported to me that 
it belonged near your Zeuxlne elatlor . from time to time X have 
received additional collections M this very interesting plant 
and each time I have exsmined it I have been impressed by its 
distinctness from J| ry 8pQOi0a of Adenostylls known to me
