elliptic-linear), acuminate, cuneate at the clasping base, 
up to 10.3 em. long and 1.75 cm. wide, (the uppermost 
and lower blades much smaller), ten or less, submembra- 
naceous. Inflorescence a short virgate few-branched pan- 
icle which is sheathed at the base and surpassed by the 
leaves, with branches very loosely 7-flowered or less. 
Flowers small, with spreading seements, greenish white. 
Sepals Heshy. Dorsal sepal oblong-oblanceolate, about 
8.5 mim. long and 8 mm. wide, subacute, 4- to 5-nerved, 
lightly concave. Lateral sepals obliquely oblong-oblan- 
ceolate, acute with a dorsal mucro, 5-nerved, about 8 mim. 
long and 3.1 mm. wide, lightly concave. Petals filiform, 
slightly broader toward the apex, obtuse or subacute, 
about 8 mm. long and 0.75 mm. wide, 1l-nerved. Lip ad- 
nate to the column nearly to its apex; lamina flabellate- 
subquadrate in outline, cordate at base, 3-lobed in front, 
about 8 mm. in greatest length and 5 mm. across the 
lateral lobes; lateral lobes obliquely ovate-dolabriform, 
spreading, with the outer margins lightly emarginate be- 
low the middle; mid-lobe smaller than the lateral lobes 
and not exceeding them in front, transversely oblong 
from a cuneate base, broadly truncate at the apex with a 
small triangular apicule in the middle; disc adorned 
throughout the center with a large oblong-ovate fleshy 
callus which is acute, lightly 38-lobulate and bisuleate with 
furrows converging toward the base. Column dilated 
above in front, extended on each side into a subquadrate 
bilobed auricle, about 4 mm. long on the posterior sur- 
face and 6 mm. long in front to the apex of an auricle. 
Pollinia four, compressed, the outer pair semilunate in 
outline, the inner pair obliquely slender-pyriform. 
KMpidendrum Macbridet seems closely similar to 4. 
parviforum Ruiz & Pav., but differs in having much 
larger flowers and a dissimilar lip.
