“II. Subgen. Trichotosia. Labellum subunguiculatum, limbo erecto v. 
patente. Gynostemium obtusum. Pollinia aequalia v. inaequalia. — Tler- 
bae cauleseentes, pilosiusculae ; caulibus simplicibus rarius ramosis, ple- 
rumque fasciculatis ; foliis sessilibus rarissime brevissime petiolatis, 
disticbis, carnosis s. coriaceis, apice saepe inaequalibus ; spicis oppositi- 
foliis, solitariis, pauci- v. multifloris ; bracteatis.” Blume, l. c. 
The commonest representative of this well-marked section in the Philippines 
seems to be E. vulpina Beichb. f. This and E. fusca Bl. were the only Tricho- 
tosias credibly reported from the Islands before the American occupation. Recent 
collections have added four species before unknown, two of them herein described 
for the first time. In proposing fresh additions to the section, it must be con- 
fessed that the elimination of such older species as have never been pictured, or 
of which some representation other than verbal has not been available, has often 
been difficult. The descriptions of the earlier botanists are now inadequate; more- 
over, even the very detailed diagnoses of present writers have sometimes proved 
ambiguous, owing no doubt to the comparative characterlessness of the species 
of this section. It is imperative that authors of new species of § Trichotosia 
publish figures exhibiting distinctive characters.
