spur-like mcntum. Lip hardly recurved, as long as the sepals spotted with dark-red
ou each side towards the base of the blade, flabellately many-uerved; claw with a
narrow median canal loading down to the short oblong recurved callus or scale.
A beautiful species, of wliicli I have seen only the dried flowers aooomprmying the drawing.
Tiie latter is inscribed "Larut, Perak, Ic. Hort. Bot. Calo. Fl. 24-9-83."

Stem 2—3 ft., narrowed at the base, no doubt pendulous; internodes 1 — 1^ by
J in., green, nodes often rooting; sheaths wliite, young green and speckled,
membranous. Raccmes 1—2 in. ; bracts small; pedicel with ovary J in. and peduncle
purplish; flower 1 in. long. Sepals and petals yellow or greenish, with red dots along
the numerous nerves ; mentum straight or slightly curved, streaked with red. Lip with
the claw times as long as the dull yellow limb, margins of claw incurved above,
below connate with the sides of the mentum. Column very short; anthei- stipitate.
A remarkable species. The analyses fig. 1, flower, with the lip displaced; 2, petal; 3, lip; 4, column

capsule attached to the drawing. The latter is inscribed " Raugoon, Dom. Gilbert misit; H. in H. B. C.
19-11-8i." It must be very nearly allied to the D. ionopuH, iieichb. f. in Gard. Ghron. 1S82 ii.
508, from Burma, which has yellow flowers with red blotches and an elongate falcate mentum ; but
that species is described as having a thick keeled claw of the lip with a flat retroae tooth. The
latter is a common character of the section Pedilonum, but I found no trace of it in the sohtary
lip o£ D. pmduHfenm which I was able to -

Slß^ 2—3 ft., pendulous, green, internodes channelled and more or less twisted.
Leaves not seen. Racemes \\ in., about 6—8-fld,; peduncles short and rachis red-brown ;
pedicels with ovary about ¿ in. ; bracts very small, ovate, acute. Sepals and petals
spreading, sub-acute, 5-nerved ; mentum nearly straight, obtuse. Lip with the blado
oblong, cordate above and below, slightly constricted in the middle.
In the Hora of British India, I have recorded this plant as a variety of D. pauditriferum, adding
tbat it may be Eeichenbach's D. íoho^jíís. A fm-ther examination of the drawing convinces me that
it canuot be either the one or the other. From D. pandurijerum it differs in the short pedicels, broadly
obovate 5-nerved petals, much shorter mentum, and above aU in the form of the lip, the blade of
which is more oblong (not deeply constricted with auricle-like side-lobes), and obcordato midlobe
and the claw is not even twice the length of the blade.
The drawing is inscribed "Kunstler misit ex Terak, PI. in H. B. C. 7-5-84."

Stem 1 ft., incurved, slender below, tuberous at the base ; roots fibrous ; internodes
in., grooved. Leaves 2¿ by f in. Raceme 1—2 in., rachis slender, ¡nuk ; bracts
minute; pedicels with ovary f in. ; flowers 1 in. Sepals and petals | in. long,
dark rcd-purplc; mentum four times as long as the sepals, nearly straight, broad, slightly
undulate, obtuse. Lip small, narrow, about as long as the sepals, claw gradually dilated
into the short lateral lobes, between which is the large semilunar callus, suddenly
contracted • into the obovate-oblong apiculate Hmb.
A very peculiar 'species, with flowers a good deal hke' those of' Tropaohm peniaphyllum.
I have seen no specimen, and have consequently described it from the diawlug, which is inscribed
"in Il.b.O. Fl. 30-8-82, &om Malaya, Perak, sent by Herr Kuustler," to which Mr. Brace (then
keeper of the Herbarium) has added in a note, " the sides of the claw of the' lip adhere to the
sidos oí the mentum," -which they do more or less in other species of the section PcdilonuM.
