nhizome densely matted, clothed with imlji-icating distichous ovate scales. Pmidobulbs
1—3 ia., broadly or navro-ffly bottle-shapedj. with dark browa large basal sheathti.
Leaves 3—0 by \ in. or less, dark green. Scapo shortei- than the pseudobiilb ; ovary
with pedicel ^ inch, decuvved; flower pale yellow with orange spots on the Hp, about
1 in. from the tip of the dorsal sepal to that of the lip. Lateral sepals oblonglanceolate,
acute, defiexed and rccurvcd; petals siiberect; lip spreading from the base
of the column, with two ear-shaped sidelobes towards the saccate? base, and a
large broadly obovato or subpandiiriform niidlobe, disk with thickened ridges. Column
winged; the wings rather dilated above the middle.
h. very douttfiil C(elog'jne, diiieriEg from its congeners apparently in the lip not embracing the
column, for Tvhioh reason it has been referred to Ptmisca by Lindley; but the lip wants tHe claw of
that geuus, and the foi-m' of the flower is much more that of a Ccclogyne. The drawing does not represent
the tlii'ee orange spots described by Wallich (according to Lindley). There are indications in figs.
1 and 3 of two fniall tubercles at the base of the lip. In the Flora of British India the scapes
instead of the pseudobulbs are by misprint described as clothed with membranous sheaths. The

Stem with the strongly ribbed ieaf-sheaths, as thick aa the middle finger. Leaves

5.ribbed on the back. Scape from among the lower leaves, at the side of the stem, a foot

in.- flowers 1—1J in. broad across the sepals; Sepals and petals all green or
ochreouB yellow for the upper half; sepals variable m width, sometimes obovate and
apiciilate; petals about half as broad; lip adnate hy the spur to tho largo long column,

broader than long, pure white, subequally 4-partite, the divaiicating recurved obtuse
seo-ments of the midlobe being very little broader than the similarly divaricating
recurved sidelobes; spur very long and slender; a minute carunoulate 3-lobcd callus is
placed at the very base of the lip close to tho mouth of the spur.
A very handsome plant. The flowers are all green, except the lip in a drawing I made of it
in Sikkim, and I did not observe the remarkable rhizome, which in plate 4i is repescnted ae stout,
horizontal,' densely fibrous, and bearing a series of closely set conical green pseudobulbs, each with sis
or sevon horizontal constrictions, and a small terminal tubcrcle, and emitting thick vermiform
roots from the joints. If these are short stems of previoiis year's growth denuded of sheaths and
leaves, they must increase veiy greatly after their denudation, for they dimmish in size as they
approach the flowermg and leafing stem which terminates tho rhizome.

Rhizome stout, fleshy, creeping, as thick as the little finger, with tuberous pseudobulbs
on the upper surface and stout vermiform roots from the lower, stem as stout
as the little finger. Leaves few, very young at flowering time, when mature a foot
long, long-petioled, oblong-lanceolate, strongly nerved. Scape 6—10 in. high or
less, raceme lax-fld. bracts in., ovate-lanceolate, green, not equalling the ovary;
pedicels with ovary | in. Sepals | in. long, ovate-lanceolate, yellow-green, sometimes
streaked with red; petals 3-nei-ved, usually more yellow than the sepals, lanceolate; lip
wliite, yellow towards the base, sidelobes sometimes incumbent on the midlobe; spur
straight, green, hardly longer tlian lateral sepals, glabrous or puberulous. Capsule
in. long.
Lindley founded C. ckìoroìekca on specimens of my own collected in Sikkim in 1848, aided by
the figure which I here reproduce. It differs from C. herhaeea (Tab. 44, also founded on Sikkim
specimens of mine) in the form of the lip, much shorter spur, colour of the flowers, and in the leaves
of this not being fully developed at the flowering time. Lindley further described, • also from a drawing
of mine, as C. ijaleaia, what 1 believe to be a faded specimen of C. chhroleiiea with sepals connivent,
thus giving a hooded appearance to the flower. The Himalaya species of Calanthe are, howev<ir, very
little known, and much more numerous specimens oi 0. chloroleuca and G. herbacea are wanted, together
with better drawings than those here given of the nature of the rhizDme, wbioh in both speoios
especially wants elucidation.
