lateralia oblongo-lanceolata, acuta, 3-nervia: petala rhombiformi-ovata, 3- 
nervia; labellum 3-lobatum, ecallosum, lobis lateralibus lineari-lunatis, ob- 
tusis, quam lobo medio minoribus, lobo medio oblongo, obtuso. 
Pseudobulbs 2 cm long, somewhat pyriform, monophyllous. Sheaths 
inflated, nigro-punctate when dry, round, acute at the apex. Petiole 
5—6 cm long, slender. Leaf ablong-lanceolate, acute, strongly 5-nerved, 
8,5—11 em long, 16—23 mm wide, broadest above the middle. Peduncle 
shorter than the petiole and leaf, or longer, 12—16 cm long, slender. 
Infloreseence 5—10 cm long, 1 em through. Flowers in a dense raceme, 
about 2 mm apart. Bracts glumaceous, longer than the ovary, 2,5 mm 
long. Flowers bright yellow, emitting an odor which recalls the smell of 
freshly sawed pine lumber. Lateral sepals oblong-lanceolate, acute, 4,5 mm 
long, 2 mm wide, 3-nerved. Upper sepal similar, narrower, 4,5 mm long. 
Petals rhombic-ovate, acute, 3-nerved, 3,5 mm long. 2.5 mm wide. Lip 
3-lobed, lateral lobes linear-crescent shaped, obtuse, erect, 1 mm long, 
much narrower than the broad oblong-lingulate middle lobe, which is 
trulliform when not flattened out, blunt at the apex and thickened at the 
base. Column exalate, 9 mm long, stout, fleshy: apex rounded. 
From between Suyoc and Panai, Prov. Benguet, Luzon, alt. about 
6500 ft., epiphyte, November 7, 1905, Elmer D. Merrill (no. 4757). 
This very distinct species belongs to a group of odd forms which 
appear to have equal affinity with the sections Platyclinis and Euacoridium.

Pseudobulbs slender pyriform, abot 2,5 cm long. Leaves 9—14 cm 
long, 7—18 mm wide, oblong-lanceolate, acuminate, acute. Petiole 4—7 cm 
long. Peduncle shorter than the leaves, flexuose. Bracts glumaceous, 
3—4 mm long. Flowers yellowish, odorless. Lateral sepals ovate-lanceo- 
late, acute, 3 mm long, 2 mm wide. Upper sepal oblong-ovate, obtuse, 
or subacute, 3 mm long. Petals ovate-acute, 3-nerved. Lip 3-lobed; 
lateral lobes minute, rounded, basal; middle lobe relatively very long. 
2 mm wide, semi-orbicular, about 1 mm long, trituberculate, with a tubercle 
on each side at base near the sinus formed by the lateral lobes and with 
a papillate tubercle between them. Column stout.

forest, alt. about 6500 ft., November 7, 1905, Elmer D. Merrill (no. 4758). 
The lip although unlike those of all other species of Acoridium is of 
great interest inasmuch as the tubercles are in character and location 
similar to those of such species as A, pumilum and A. venustulum. In 
habit the plant resembles A. Whitfordii and A. philippinense.
