L!y dear Lankester: 
llsiit week I ex'peot to issue another one of 
my endless effusions, Sched. Orck. no. 6, In it you will find 
several new species from your collections. I hope Schieehten’s 
forthcoming paper does not undo our work and crowd the already 
unoomfortable realm of synonymy. 
The little Pleurothallis with round leaves 
I have described as a novelty. It is suspiciously close to the 
Cuban P. nummularia, but I think differs in several points of 
structure that are of specific value. 
Maxon found a close ally of your E« obesurn. 
He obtained it on the MombaCho Volcano in Nicaragua. I take it 
to be E, lacuetre Lindl* a rare species only known from Venes- 
ulsa heretofore. It differs frora E, obesurn in the structure of 
the labelluxa. Ilaxon sent living plants to Powell. Would It not 
be well to send Powell some living plants of E. obesurn? I would 
welcome additional dried specimens for studies of variation# 
Here are a few determinations for you: 
471 . Pichaea suaveolens Kraenzl. Heretofore 
only known from Guatemala. 
455* Bepanthes elata Reichb. f. But not typi¬ 
cal . 
482. Pleurothallis Sanohoi Ames. 
453. Pleurothallis Cogniauxiana Schltr, There 
were no flowers with this. The vegetative characters match the 
species named. More material v/oul be welcome! 
ilaxon 1 s Costa Rican specimens have been a great 
joy to me . Wonderfully preserved and quite satisfactory.
