DENDROBIUM Sw. 
Dendrobium albayense sp. nov. (§ Aporum, Hemiphylia). 
Cum D. cuneato Schltr. comparandum videtur, a quo tamen 
foliis differt. Caulis ad basim teres, foliosus, compressus, 
anceps. Folia disticha, lanceolata a latere visa. Sepala late- 
ralia triangulari-ovata, obtusa. Sepalum superius oblongum 
obtusum, subquadratum. Petala ligulata, obtusa. Labellum 
cuneatum ad apicem 3-lobatum. Lobi laterales divaricati, 
obtusi. Lobus medius obtusus. Prope apicem labelli callus 
bilobus. Mentum brevem, obtusum, rotundatum. 
Plants up to 3 dm in length, simple or with a few branches, 
leafy to about the middle, floriferous portion of the stem leafless. 
Leaves distichous, lanceolate, acute, when viewed from the side, 
1.5 to 3 em long from tip to point of insertion; at the middle 
of the leafy part of the stem 1.5 cm long from tip to inner angle 
formed with the stem; free portion up to 1 cm wide. Lateral 
sepals fleshy, broad, triangular-ovate, subacute or obtuse, about 
3.5 mm long, 2.5 mm wide. Upper sepal fleshy, 3 mm long, 2.5 
mm wide, rounded at the tip. Petals ligulate, obtuse, 3 mm 
long, 1.5 mm wide. Labellum equaling the lateral sepals, 3.5 
mm wide at the tip, obscurely 3-lobed in front, lateral lobes 
divaricate, obtuse, about 1 mm long to the angle formed with 
middle lobe, middle lobe shorter than the laterals, obtuse, forming 
with the cuneate-bilobed callus above it a shallow pocket.

Dendrobium angustifolium (Blume) Lindl. Gen. et Sp. Orch. 76. 
Desmotrichum angustifolium Blume Bijdr. 330; Krinzlin in Engl. 
Pflanzenreich 45 (1910) 350. 
The material which I refer to this species exhibits several 
slight variations from authentic specimens of D. angustifolium. 
These slight variations seem to me unimportant. I have exam- 
ined living material collected by Elmer D. Merrill on Mount 
Mariveles in 1905.
