lihizome stout, woody, clothed with adpressed lanceolate scales. Stma 2 feet long,
rising about 1-5 in. apart, sub-cyHndric, clavate, many-leaved. Leaves liucar-oblong,
thickly membranous, the apices blunt and notched, narrowed below to the short subtubular
sheath; length 3'5 to 4-5 in., breadth to -5 in. Capitiila hemispheric, 1-25
in. in diam., densely crowded. Flowers -125 in. wide, yellowish; Jloral hract naiTow,
ovate, acute, half as long as the oyHndric sessile ovary'; bract of suppressed pe<liccl
spathaceous. i^epals ovatc-orbicular, blunt, concave. Palais narrower, blunt. Lip as
long as the sepals, oblong, 3-lobed; the side lobes rounded and with a large callus
between them at the • base; apical lobe broadly ovate, the apes broad, entire or very
slightly notched. Column short, not winged at the apex, its foot also short. Tip of
anther emarginate; pollinia sub-equal, attached to a small viscus.
Sikkim, in the valley of the Teesta, at an elevation of 1,200 feet; in flower
during August; Pantling, No. 459.
A species allied to A. callosum, Reichb. fil., but differing from that species in its
larger heads of smaller flowers, and in its broader leaves. This differs from A. brevipes
in having a single basal callus on the lip and in having no caili on the disc above
the base. The flowers arc of a uniform yellowish colour throughout.

lihizome stout, branching, clothed with thick triangidar scales -20 iu. long. Stems
rising from the rhizome 1 or 2 in. apart, ei-ect, one or two feet in height, slender at
the base and only slightly thickened upwards. Leaves numerous, sessile, linear-oblong,
tapering gradually from the base to the notched apex; length 6 in., breadth at the

Iract spathaceous, aboiit as long as tho sessile ovary. Sepals ovate, blunt. Petals
broadly elliptic, very obtuse. Lip 3-lobed; the side lobes broad, rounded; the apical
lobe decuiTed, ob-reiiiform, the apes, emarginate; the basal callus large, divided into
two diverging lobes each ending in a thickened blunt point opposite the sinus separating
the apical from the basal lobes. Column stout, with a short foot. Lip of anlher entire.

Siklum, common at elevations of about 6,000 feet; Pantling, No. 477; in flower

The flowers of this are of a reddish colour. Tho gland of the pollinia is not truly
Vandaceous, and is in reality only a globular viscus to which the pollen masses aro
attached by elastic thi-eads. The relation to this to A. brevipes has been explained
under that species.
