Slems tufted, 6—18 in. Ion», as thick as a crow-quill, greou, narro'wecl towards
tbc base, clothed below with long brown sheaths; interuodes about 1 iu. Leaves 2—3
in., ^ iu. broad, straight, suberect, bright green, obtuse, or very obliquely truncate
at the flattened apex, with a rather acute triangular point. Flowers fow, fragrant,
produced in the very long leafless apex of the stem, which is closely invested by two
or more long appressed pale sheaths an inch long; pedicel very short, issuing from a
short annular sheath (? bract); perianth rather nan-ow, f iu. long from the tip
of tlio dorsal sepal to that of the mentum, which is yellow ; lip white with pink
l a the Flora of British India I desoribod tliis species from Lindley's diagnosis and a very
imperfect leafless specimen. The fins di-amng here reproduced enables me to amend the desm-iption;

Hab.—Tesasserim ; at Moulmein, Parish. Singapore (IG. in. Eerh. Calcutta).
Stem 6—10 in., rather flexuous, sheaths red-brown, lower inetmodcs 1—1| in. Leaves
3—4 by ^ in., grass-like, bright-green, dorsally convex, channelled above. Flowers
from the lower axils, nearly i in. long ; pedicel hardly any, with the ovaiy decurved,
reddish. Sepals and 3-nerved petals dull yellow with brown streaks along the nerves,
which are continued to the base of the mentum; lip as long as the sepals, thickish in
textm-e, nearly straight, concave, dull pale yellow with a green tip, nerves faint. Column
very large for the genus, stoiit, 3-toothed at the top.
The drawing here reproduced enables me to give a more complete desoription of this epeoies than
that contained in the Flora of British India. It is inscribed " Singapore, 14-6-68. Fid. March
1869." Possibly this is an error due to transposition o£ labels, a very common ocoiurrence in
gardens; for the only other known habitat of the species is Moulmein, whence I have seen specimens
collected by Parish and accompanied by a drawing, which leaves no doubt of the identify of the
supposed Singapore plant •with his. The great length of the column is remarkable, aad shows an
flfSnity with D. nutans (see t. 18).

globoso, sccuudo et tertio gracilibus, quarto supra medium clavato, quinto incrassato

Hab.—Andaìian Islands, {le. in Eerh. Eort. Cakutta).
Slems tufted, 10—12 in., very slender above, base swollen into a globose tuber
emitting fibrous roots, two following internodes very slender, the next davate
ribbed, followed by a cylindiic ribbed oue an inch long, and this by an obversely
davate one, the rest all 1—l^- in. long, very slender, with appressed sheaths. Leaves
on the young stems only, 3—5 in. long, slender and recurved, in. broad, acute.
Flowei's about f in. long from the tip of the dorsal sepal to that of the mentum,
very membranuus; petals as long as the dorsal sepal, nerve solitary with branching
nervules. Lip delicately 5-nerved in the centre, the outer paii- of nerves branching
towai-ds the mai-gins. Column veiy short, 3-toothed; anther hemispheric.
As stated in the Flora of British India, this spocies is there described from the drawing here
reproduced (which is inscribed " Andamans, liecd. 8-2-S4, fid. m Ilort. Bot. Cale. 30th April 1884"),
and some detached flowers placed ia a pauket with the drawing. It seems to be quite distinct from
any previously described, but it belongs to a very troublesome group with swollen lower internodes
the characters afforded by which latter organs are not likely to be constant.
