April 2M, 19SO 
My dear Dr. Sohlechter: 
Your letter of the second of April 
arrived this morning. I was delighted to receive it, and 
most interested in the enclosures although the list of 
additions to the Phillipine orchid flora rather annoyed 
me as 1 shall have to ascertain ;!ust what Kraenzlin has 
described. Unfortunately his papers have not- reached me 
and I shall be unable to check up his work with the list 
of new species that I am putting out in the sixth volume 
of Crehiaace&e. If there is any way in which you can se¬ 
cure for me material or sketches of the new species I will 
be more than obliged. As 1 nave given so much time to the 
Philippine flora I want to keep my records complete and 
be able to interpret the work of other orchidologists. 
I have seen nothing from uhe Philippines that in 
any way mathohes Pendroohilum saq colabium Kraenzl. and 
I am inclined to doubt very much if the original plant 
came from the Philippine flora. I do not recognize the 
genus from the sketches you enolose and I am not inclined 
to commit myself as to its position. 
I have been working on Spiranthes again in the light 
of your very helpful monograph, I am sorry that you did 
not cite specimens and give more information as to dis¬ 
tribution, In spite of your notes I am unable to clarify 
the S. sinensis puzzle, although from my studies of the 
Robert Brown 'l?ort Jackson plants in my herbarium I can 
readily see that the Australian plant is not to be con¬ 
fused with the small flowered Chinese on©, I have materials 
from China, collected by McGregor that seem to fit _S- 
3tyl8tea . but I am not sura of my diagnoses. If you have 
sketches of this species I would welcome copies. The Indian 
species I have examined seem to constitute a distinct type, 
and I am about ready to agree with your treatment of S, 
crisgata, I would like to take up Spiranthes as you have 
limited it and publish a good paper on it. I ara now begin¬ 
ning to assemble material for this purpose and I hope you 
will send me some of typical Rev; Guinea species. In fact 
duplicates of Spiranthes from any part of the eastern 
tropics will be very much appreciated. I have a very friend¬ 
ly feeling for the genus since my struggles with the spewies 
of the Barth American flora aroused a strong liking for 
spiral-flowered Spiranthes.
