The flowers are of a uniform pale yellow colour, tho lamellaj on tho lip being
red. They are short-lived, not suiviving more than two days. The species is allied to
E. confim^ Ilook. fil., but differs in being quite glabrous and in having pseudo-bulba
without nodes. It has not hitherto been recorded from Sikkim; but there are in the
Calcuita Herbarium two drawings made by the late Dr. Simons from specimens collccted
by hitn in Assam. There is also a specimen obtained by Mr. J. L. Lister near Chitta
gong. The larger form of this, which has been separated as var. Eiirzii, extends through
Burma to tho Andaman and Nicobar Islands.

pt. 2, p. 121.
Rhizome -15 in. thick, jointed, smooth, with a few short membranous sheaths.
1-5 to 2 in. apart, 1-25 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
tlu'ee, membranous, narrowly lanceolate, tapering to each end, sessile, 4 to G in, long
and '8 to 1 in. broad. Scapes rather shorter than the leaves, one or two from the
summit of tho pseudo-bulb, each enveloped for more than half its length by a narrow
convolute sheath; raceme stout, erect; floral hract nearly obsolete, and represented by u
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 petals oblong, blunt. Lip oblong, with two rounded oblique lateral lobes near tho
apex, the short caruncled rounded mid lobo with fivo to seven vertical lines, the edges
entire, the disc between the side lobes with threo parallel raised slightly sinuous vertical
lines. Column long, rostellum flattened against tho back of tho clinandrium. Stigma
small, with two sub-globular convexities inside its lower margin.
Sikkim, not uncommon at elevations of 3,000 to 5,000 feet ; flowering during
February aud March; Pantling, No. 359.
This species in many rospcets resembles E. vittaia, Lindl. (of which it may possibly
bo a cloistogamic form), but is a much smaller plant, with smaller pseudo-bulbs and
shorter and ercet raceme. The flowers of both aro similar in form, with the exception
that the lip of this has lateral lobes, while in E. vitiata the lip is entire; and that the
disc of this has threo elevated vertical lines on its surface, whereas the lip in E. vittata
has five crenulate wavy ridges. The colour of the flowers of the two also differs, those
of this specios being pale greenish with brown streaks on the Hp only; whereas the
flowers of E. vUtata are green with prominent brown streaks on all their parts. The
