$3r dear Mr. Powell: 
Tom* letters of the 14th & 15th are 
just here. 2 have examined the Hex&desmia species once 
sore and I find that #22? as represented in the herb¬ 
arium matches vegetatively the fragment you have rob¬ 
ed ttecl and the sketch of your herbarium specimen* It 
would seem that you have mad© no mistake • '..'he trouble 
lies in the description prepared by bohleohter, It does 
not measure up to that degree of aocuraoy which one 
pools when examining 00 -types# Tour explanation seems to 
leave no room for doubt as to ;i« mShyimlhSS. Up to the 
present time I have not succeeded in matching your 3143 
with any described species* It mny he new. But I must esy. 
anine it more carefully.! will compare it with &Mh2C- 
glottis laevilaMum following you* suggestion.

As to the Habenarta materia ;-ent 
Oct. 2th, one* Deo. fth, last year, I think the specimens 
represent a single species* kof the present I thin! we m*y 
accept hohleehter'e* conclusion. But I im anxiously wait®*, 
ing for authentic rv terial of £* fell ^JjOjjsie. findl, to cone 
in it: r,n brazil before arriving at a definitive opinion, 
fhe pc|nt of chief interest for you is the fact that the 
variation in flower-size does not, as X view it now, in¬ 
dicate the existence of more than one variable species.
