OAKES AMES 
R ecent studies of tropical American orchids have 
brought to light species which seem to be undescribed 
or which have been inadequately described. The following 
descriptions have been prepared from herbarium material. 
The arrangement of the genera follows the sequence proposed 
in Engler and Prantl’s “ Die Pflanzenfamilien.” 
Gomphichis foliosa Ames sp. nov. Herba valida, 
foliosa, folds ligulatis utrinque attenuatis. Racemus densi- 
florus, glanduloso-pubescens. Flores numerosi. Sepala 
lateralia elliptico-oblonga, glandulosa. Sepalum dorsale 
simile. Petala anguste oblongo-elliptica, ciliata, externe 
glandulosa. Labellum incrassatum, anguste ellipticum, 
obtusum, basi bicallosum. Columna valde curvata, antice 
glandulosa. 
Plant about 60 cm. tall, basal portion leafy. Roots very 
coarse, 5 mm. in diameter. Leaves oblong, tapering toward 
both ends, sheathing the stem at base, about 15 cm. long, 
nearly 1.5 cm. wide, thickish, acute, obliquely ascending, 
concealing the basal part of the stout stem, passing above 
into spreading foliaceous bracts. Raceme densely flowered, 
nearly 10 cm. long, 12 mm. in diameter, scape below the 
raceme glandular-pubescent. Rachis glandular-pubescent.
