Nasu: Costa RICAN ORCHIDS 115 
On moist forested slope, Finca Navarro, xo. 6g. Hemsley, 
/. ¢, reports this from Mirador, southern Mexico, and from 
Chiriqui, Panama. Its detection in Costa Rica, therefore, was to 
be expected. Mr. Maxon in his field notes describes the flowers 
as yellow. This species was originally described from Jamaica. 
PLEUROTHALLIS POLYLIRIA Endres & Reichenb. f. 
Gard. Chron. 32: 1483. 1871 
On tree bordering the Agua Caliente, Finca Navarro, wo. 702A. 
This pretty species, one of the larger members of the genus, is a 
free bloomer, sending up usually several racemes from the same 
leaf. The flowers hang in a somewhat secund manner, giving the 
inflorescence an appearance resembling that of the lily-of-the-valley. 
Originally described from fresh living matetial sent by W. W. 
Saunders to Reichenbach, who does not state from what country 
the plant was derived. A herbarium specimen, collected in Costa 
Rica by M. Endres, is, however, referred to as being the same, so 
that the indications are that that country is the native home of this 
interesting plant. 
PLEUROTHALLIS MINAX Reichenb. f. Bonplandia 2: 24.

na tree bordering the Agua Caliente, Finca Navarro, ”o. 707. 
I have taken up with some hesitation Reichenbach’s name for this 
Plant, instead of that given by Lindley, who originally described 
the flowers as « green, with a little purple dotting on the inside,” 
and gave the home of his plant as Trinidad. Later (Folia Orch. 
Pleurothallis 27. 1859) he makes this statement: ‘‘ Flowers green 
in gar dens, orange coloured wild,” and refers to his species a speci- 
men collected by Fendler in Venezuela, 20. 2152, and also material 
secured by Wagener at Caracas. He further remarks thus: “ The 
dissection of a flower of his P. minax given me by Prof. Rchb. 
and Fendler’s specimens show that plant not to be distinct from P. 
Plumosa.” A specimen secured by Wagener at Caracas, at an 
Elevation of 5000 feet, and presumably the one to which Lind- 
ley refers above, was the basis of P. minax. The plant which Mr. 
Maxon secured came into flower in the early part of November of
