Your remarks about Pleurothallis Hunteriana 
are interesting. If your suspicions are justified, then we must 
accuse Schlechter of improper description. He gives the petals 
as 1 nerved. In P. harnta, they are 3-herved. He described the 
sepals as free. In P. hara&ta they are united to about the middle. 
And then again, what is Mas de vail la aperta ICraenzl. ? I think 
it is P. hamate. But Kraeaalln described the sepals ns keeled 
on the upper surface. Did he mistake the keel for the inner mar¬ 
gin of the sepals? I have yet to take this matter to Kraenslin, 
but I intend to do so shortly. 
On your field labels please include the year. 
And, when possible be more definite. Maxon does not approve of 
"Hills east of City,"Localize specimens as closely as possible. 
The field data are of deep significance. Then age instate whether 
the date given refers to the flowering time in your garden or to 
the date when plant was collected. While these data may be a 
nuisance, they are essential for the geographical notes, 
Sched, Orch, 6, over one hundred pages, comes 
out on Saturday. 
I have begun making your field specimens ready 
for the herbarium, I wish you could see how they look, I was pleas¬ 
antly surprised to see what a fine showing they make. You have 
done agreat piece of work. If you keep on, and Improve In your 
methods, you will have assembled the best exemplification of Pan¬ 
ama orchids in th>. world. I think you have already done that, 
I have been making an exhaustive study of Pleu¬ 
rothallis BrighamiS Wats. To this species I refer your 274 & 275. 
I am figuring this species in Sched. Orch. 7. Also P, glan&ulosa. 
to Your specimens now hold the field and I will 
send/you the determinations as they accumulate. 
Yours always faithfully.
