along nearly its entire length, the two lateral being dilated in the basal half and 
having glandular margins, the middle one minutely papillose in its basal half. Column 
stout, its foot short. Anther with a truncate incurved lip. Pollinia in fours, compressed, 
attached by their backs to a granular membrane. Reichb. fil. in Walp. Ann, VI, 277;

The flowers are of a uniform pale yellow colour, the lamelle on the lip being 
red. They are short-lived, not surviving more than two days, The species is allied to 
E. confusa, Hook, fil, but differs in being quite glabrous and in having pseudo-bulbs 
without nodes. It has not hitherto been recorded from Sikkim; but there are in the 
Caleutta Herbarium two drawings made by the late Dr. Simons from specimens collected 
by him in Assam. ‘There is also а specimen obtained by Mr. J. L. Lister near Chitta 
gong. , The larger form of this, which has been separated as var. Kurzii, extends through 
Burma to the Andaman and Nicobar Islands.

Rhizome *15 in. thick, jointed, smooth, with a few short membranous sheaths. 
Pseudo-bulbs 1:5 to 2 in. apart, 1:95 to 1:5 long and ‘75 in. in diam., ovoid-ellipsoid, blunt 
at the apex, the bases clothed with the fibrous remains of sheaths. Leaves two or 
three, membranous, narrowly lanceolate, tapering to each end, sessile, 4 to 6 in. long 
and "8 to 1 in. broad. Scapes rather shorter than the leaves, one or two from the 
summit of the pseudo-bulb, each enveloped for more than half its length by a narrow 
convolute sheath; raceme stout, erect; floral bract nearly obsolete, and represented by a 
slightly thickened ring at the base of the stalked ovary. Flowers from 15 to 20, about 
-3 in. long, slightly shorter than the ovaries, the buds often not expanding. Sepals 
and pelals oblong, blunt. Lip oblong, with two rounded oblique lateral lobes near the 
apex, the short caruncled rounded mid lobe with five to seven vertical lines, the edges 
entire, the disc between the side lobes with three parallel raised slightly sinuous vertical 
lines. Column long, rostellum flattened against the back of the clinandrium. Siigma 
small, with two sub-globular convexities inside its lower margin. 
Sikkim, not uncommon at elevations of 8,000 to 5,000 feet; flowering during 
February and March; Pantling, No, 359. 
This species in many respects resembles Æ, vittata, Lindl. (of which it may possibly 
be a cleistogamic form), but is a much smaller plant, with smaller pseudo-bulbs and 8 
shorter and erect raceme. The flowers of both are similar in form, with the exception 
that the lip of this has lateral lobes, while in Æ. vittata the lip is entire; and that the 
disc of this has three elevated vertical lines on its surface, whereas the lip in Е. vittata 
` has five crenulate wavy ridges. The colour of the flowers of the two also differs, those 
of this species being pale greenish with brown streaks on the lip only; whereas the 
flowers of E. vitiata are green with prominent brown streaks on all their parts, The
