any free peduncle, with the rachis about 16 cm. long, 
the lowest branch erect and mostly concealed by a loose 
scarious conduplicate spathe about 6 cm. long. Floral 
bracts mostly linear-lanceolate, scarious, more or less 
shorter than the slender glabrous pedicellate ovary. 
Flowers rather small for the genus with spreading seg- 
ments, with the ovary, sepals, and petals dark red, and 
the lip pink to white. Sepals 3-nerved or obscurely 5- 
nerved below. Dorsal sepal elliptic-oblanceolate, sub- 
acute, about 1.5 cm. long and 5—5.6 mm. wide. Lateral 
sepals broadly and very obliquely elliptic-oblanceolate, 
acute, dorsally carinate with the keel produced into a 
prominent mucro, about 1.63 cm. long measured along 
the posterior portion and 6 mm. wide. Petals obliquely 
oblanceolate-linear to linear-spatulate, more or less 
curved, acute at the sometimes rounded apex, 1-nerved, 
about 1.35 em. long and 2-2.6 mm. wide above. Lip 
adnate to the column up to its apex; lamina conspicu- 
ously 3-lobed near the middle, cordate at the base, retuse 
and bluntly apiculate at the apex (of the mid-lobe), about 
9 mm. long through the middle and 14-17.5 mm. wide 
across the lateral lobes when expanded; lateral lobes 
obliquely rounded-dolabriform, with the outer margins 
minutely and irregularly crenulate; mid-lobe short, 
much broader than long, from a broad base more or less 
abruptly dilated into a pair of short rounded minutely 
crenulate lobules; disc at base with a pair of small fleshy 
calli and thickened through the middle. Column strongly 
and abruptly dilated in front from below the middle, 
rounded-retuse at the apex, about 6.8 mm. long at the 
back. 
This species differs from the Colombian Hpidendrum 
Sanctae Martae Schltr. in having broader leaves, an in- 
distinct (rather than elongate) peduncle, as well as in 
dissimilar petals and lobes of the lip. It varies from the
