Baguio; the origin of the specimens is not known, but we are 
assured that the orchid peddlers in Baguio collected them from 
the mountains in the vicinity of Baguio. 
A species closely allied to Agrostophyllum inocephalum. 
(Schauer) Ames, but differing radically in the shape of the 
epichile. 
Genus DENDROBIUM Swartz 
DENDROBIUM AURICULATUM sp. nov. Plates 1, G, and 18. 
Aff. D. papilio. Caulibus simplicibus, basibus foliorum auri- 
culatis, floribus albidis et basi auriculata labelli plus ovati differt. 
Stems numerous, crowded in a clump, 30 to 82 cm high, erect 
or suberect, not branched, terete, greenish yellow, 1.5 to 3 mm 
in diameter; internodes up to 2.5 cm long. Leaves linear-lan¬ 
ceolate, the apex narrowed, acute, unequally bilobed with the 
subulate lobules 1 to 2 mm long, the base prominently auricled 
with the lobules extending across the stems, the lamina 8 to 12.5 
cm long, 4 to 8 mm wide, somewhat rigid; the sheaths tubular, 
purplish. Flowers odorless, showy, appearing singly on the 
naked termination of the stems, 6 to 6.5 cm across. Flowering 
stems usually defoliated (if leaves are present when the plant 
is in flower, only the apical ones remain). Pedicellate ovary 
slender, 1.8 to 2 cm long. Sepals and petals pure white, lined 
at the base with purple. Lateral sepals oblong-lanceolate, ob¬ 
tuse, including the spur 4 to 4.1 cm long, obtuse, greenish and 
lined with purple. Dorsal sepal oblong, obtuse, 2.5 to 2.6 cm 
long, 1 to 1.1 cm wide at the widest portion, 7-nerved. Petals 
obliquely oblong-elliptic, obtuse, 2.5 to 2.7 cm long, 1.1 to 1.2 cm 
wide, 5-nerved. Labellum conspicuously unguiculate, simple; 
claw linear, the lower third tubular saccate, 1.9 to 2 cm long, 
conspicuously green, lamina (when expanded) broadly ovate- 
cordate, obtuse, margins minutely dentate or crenate-dentate, 
membranaceous, 2 to 2.1 cm long, 1.5 to 1.6 cm wide, with three 
obscure central lines throughout, pure white. Gynostemium very 
short and stout, clinandrium tridentate with the central tooth 
linear-subulate, extended into a long foot, including the foot 
1.9 to 2 cm long. Anther oblong-ovoid, obtuse, about 3 mm long, 
2 mm wide. 
In the herbarium of Oakes Ames is a plant from Mindanao 
representing this species. It differs from the typical specific 
form in its conspicuously smaller flowers of which the petal is 
1.5 cm long and about 6.5 mm wide and the entire lip, including 
the claw, about 2.5 cm long. Its data are Mindanao, District
