Dear Mr, Lankester: 
As I wrote you seme time ago, 1 am having my idea of 
your letter of June 4 transcribed. Rather than do as Mr, Rolfe 
did and 4 escrilt>e "some mighty queer thing:s" to your pen, I am 
sending a copy of the transcription for your correction and 
emendations, 
I have had another letter from you this morning, in which 
was enclosed a specimen of Tleurothallis. I shall get at it 
very soon and try to send you a determination of it, 
Je do not have a single specimens in our herbarium of 
Mesosoinadium arscewic 2 ii . but we do have the figure of it 
from ReichenWeirpublished in Xenia Crchiciacea . and I enclose 
herewith pertinent pa ts of that figure! You will notice thu*t 
the lip is quite different in shape and has a different callus 
from ^spaeia pusilla . You will notice from the lateral view of 
the lip and'"column that the lip is free from the column to the 
base. The leaf and inflorescence sfiieh I have sketched crudely, /‘3 
are also quite different. 
Following your suggestion I have looked into the combination 
which was made of Masdefallia fimbria ta to leurothallis . Those 
two genera along w ithStelis, some Lepanthes , ! J kysosiphon and some 
of the other pieurothaL 1 oids, are a eadache. Really, there is 
no good generic distinction in the lot, but it would be a crime to 
put them all together. 
I am glad that you are enjoying the American Orchid Society 
Bulletin and I hope that 1 can get an occasional note or artict^D 
from you to put in it.
