My dear Powells 
Just a few lines to accompany a check 
for two hundred dollars. 
I have decribed the new species of 
Rolfea in your honor. I expect to get this to press 
within a few days. I have been held up by the slow 
progress being made with the illustrations of PI enro¬ 
be 
thallis. Sphere must/thirty or mere species already 
done, most of them Costa Rican* I think this attempt 
to record ay recent proposals in a highly technical 
genus will meet with your full approval and give yon 
something definite to turn to vixen you wish to see 
what I have done in the past year. If all goes well I 
intend to keep issuing plates of Central American, spec¬ 
ies. 
By this time you must have had a delight¬ 
ful meeting with Standley, Cell me all about it when you 
write again. 
Yours faithfully. 
With the best of good wishes for you and your daughter 
in which Mrs. Ames and Pauline join, I send you holiday
