APRIL, 1923. THE “ORCHID REVIEW. 10g 
In the classification made by Dr. Schlechter in 1918 of the Panama 
Orchids, Epidendrum with 18 species stands at the top, followed by 
Onaidium with twelve species, while of Pleurothallis only three were known. 
Now we have an entirely new picture unfolded before us. At the above 
date it was possible to name 54 genera as appearing in the Panama territory, 
one of which was subsequently withdrawn, but through the researches of 
Mr. Powell no less than 19 more have been added, bringing the total number 
of genera up to 72. 
Dr. Schlechter states that so far as he can observe, the territory covered 
by Mr. Powell’s collection does not extend above 5,000 feet on the Chiriqui. 
But it is to be assumed that above this limit many more species will be 
found. According to the statement of Von Warscewicz, there must exist 
at an altitude of from 7,000'to 8,009 feet a particularly luxuriant Orchid 
flora. At this altitude there exists the not yet re-discovered Cycnoche- 
aureum, Sobralia Warscewiczii, Oncidium bracteatum, Oncidium Warsce- 
wiczii, and probably also Fregea amabilis. 
From a botanical standpoint, the forests extending between the Canal 
and the boundary of Colombia are unopened territory. They will 
undoubtedly disclose many new species, as they have remained preserved in 
their primitive state. It is expected that many inhabitants of the soil, 
especially species of Habenaria and the Spiranthinz, and other terrestrial 
Orchids, will be found, the comparatively great lack of which has already 
been noted in the Panama flora. 
The field of Mr. Powell’s research covers mainly the vicinity of the City 
of Panama, which, in contrast to the Republic, is always designated as 
Panama City, and further on to the Chiriqui territory at an altitude of 
about 5,000 feet. With the single exception of Oncidium Isthmi, all the 
species have been collected by Mr. Powell. 
Following an analytical table of the various genera and species, Dr. 
Schlechter concludes his introductory remarks by stating: ‘‘ The foregoing 
enumeration will not form the conclusion of Mr. Powell’s activities in 
Panama. New consignments are being constantly received from him, and 
I hope that as soon as he considers that a certain limit has been reached we 
may be able to publish a comprehensive work on the Orchid flora of Panama. 
By that time there may be found over there other interested parties who 
will assist in furthering the work. There is still much to be done. Above 
all it will be necessary to thoroughly explore the Chiriqui above the 5,000 
foot level, and also to pay visits to the territory situated between the Canal 
and the boundary of Colombia, and, finally, to devote special attention to 
the terrestrial Orchids in the soil of the forests and the savannas. We 
cannot sufficiently thank Mr. Powell for the devoted activities of his cwn 
investigations, which, in spite of his advanced years, he has manifested.
