Genus Dicuaa, Linn. 
D. prora (Itchb. f. MSS.) Densissime ceespitosa, caulibus ancipitibus 
distiche dense foliatis, vaginis ancipitibus, laminis lineari-lanceolatis 
acuminatis obliquis, floribus axillaribus vagina stipante ochreata, 
bractea cyathiformi, utrinque apiculata, ovario a bractea obcelato 
levi, sepalo dorsali triangulo acuminato convexo, sepalis lateralibus 
subeequalibus amplioribus, basi retrorsum saccatis, tepalis cuneato- 
ligulatis acuminatis, labello unguiculato sagittato disco omnico levi, 
columna pandurato constricta, ligula inferiori foves oblique pro- 
ducta. 
One of the novelties introduced by W. W. Saunders, Esq., 
from Trinidad. The true Dichrea graminoides, Rechb. f. (Cym- 
bidium granunoides, Sw.!), is totally distinct, distinguished by a 
keel running over the superior half of the lip. The Isochilus 
graminoides, Hook., comes very near Dichrea brachypoda, 
Rehb. f., having concolorous flowers, broader leaves with more 
numerous nerves, a broader lip with more numerous nerves, 
divaricate not retrorse teeth to the lip, much broader simply 
acute sepals, &c. 
Cespitose. Roots filiform, often undulated, even from the 
upper parts of the stems. Stems reaching the height of five 
inches, with many distichous leaves. Sheaths ancipitous. La- 
mine lineari-lanceolate, acuminate, oblique, nearly perpendicular, 
glaucous. Flowers axillary. Flower-stalks nearly equalling the 
lamine of leaves, purplish. Sheaths acute, ochreate. Bracts cya- 
thiform, with two bristle-like ends, one longer than the other. 
Flowers light leek-green, with purplish dots. Column whitish. 
Anther-case and inferior lip of stigmatic hollow purplish. Upper 
sepal triangular, acuminate, convex. Lateral sepals nearly equal, 
wider, saccate at the base. YTepals cuneate-oblong, acute. Lip 
unguiculate, sagittate, without any crest. Colwmn, as seen by 
ourselves in half-a-dozen flowers, constricted at the base, amph- 
ated around the stigmatical hollow, and narrower above near the 
unbordered androclinium. Anther-case depressed, foveolate in 
the middle.  Pollinia pear-shaped, depressed, in incumbent
