thinae, as also many other terrestrial orchids of which there 
has been as yet a relatively small number in the Panamanian 
flora. Let us hope that Mr. Powell may visit these regions 
and so increase his great contribution to orchidology. 
‘“*The field of Mr. Powell’s investigation extends principally 
in the neighborhood of the City of Panama, which, in the 
cepublic, is always spoken of as ‘Panama City’; further on 
the Chiriqui range to a height of around 5,000 feet. I have 
intentionally avoided expressing the height as given on the 
herbarium specimens in meters and therefore emphasize that 
they are given in English feet. 
‘“With a single exception (Oncidiwm Isthmi) all the species 
are collected by Mr. Powell. Only the number in his eollec- 
tion will therefore be cited. 
‘‘For the purpose of a review I give here a summary of 
the genera, which have representatives in the collection. With 
each is given the number of species and the number of novel- 
ties. A few species, 6 in number, which cannot yet be named 
with certainty are omitted and will be left for a future 
occasion.
