T' consider the early break! rg down of the poller tetrads as a deep 
seated character in cl ssi f icei i or., Ke+tsteir: to the contrary not wi that and! woy- 
ar.d I hope that you rill agree with mo that it indicates a clear mark of 
generic distinction between Po£er.i a oyh'iogl ossoi des and its allies. 
I have no material of Pogbnis FaderoX, F. lutea,* F n-it. ; 3da,• F. debili'a 
or P. W&gfeneri. I must, depend cn you for corf 1 rmatory notes ae to the- 
reticulated pollen holding as a generic character as far as these specie® 
are concerned in the Pogonia complex. 
T am still of the- peel live opinion that Fop. m.ex-icana Fats. Is con spec*, 
ific with Triphera trianthophora. Fy reason for this opinion is based on 
two specimens,' or rather collections, made in the same canyon by Pringle'. 
The type was collected in /ug'ust and the flowers were well past their prime 
In July of the following' year Pringle gathered what I take- to be a topotype 
The material 7 have examined is surely referable to Triptioro tri anthophora. 
T agree- that the type- material of Fog on is, me-xl’cana has a very different as¬ 
pect from the- usual specimens of T. trianthophora one meets with in herbaria^/ 
but after you have seen a wide range of material it is quite- clear that ex¬ 
treme habits'] variation i's characteristic:, even in the some--locality. Yojr 
apparently have good reasons for a difference of opinion and T shall be- de- 
lighted^leern what they re. 
Ye have had a very trying' time- here in the publishing' business and T do 
not believe that we should attempt to go to press just yet,. Tt will be well 
to work along' and assemble a goodly supply of manuscript-.; then when the- pro 
per time' arrives it wi ll be .possible 1 to bring' out the- different parts of cuf' 
Folia in rapid sequence,—in sufficiently rapid sequence to convince the 
public that we ore in earnest and prepared to push our product with con¬ 
scientious ardor. In the- meantime-, « however, X must await your reaction to 5 / 
my last letter. You will,- 1 am sure,' agree with me that something' more than 
ineistance' is necessary in the realm of joint authorship if amicable re-
