156 CXLVIII. ORCHIDEZ. (J. D. Hooker.) [ Habenaria. 
MALAYAN PENINSULA ; on Mt. Ophir, Griffith (Kew Distrib., 5359), Lobb, PERAK, 
Scortechini, alt. 7000 ft., Wray. 
Root of thick tomentose fibres spreading from the crown, which gives off one or 
more long-petioled leaves and a tall rather slender scape. Radical leaf 4-6 in. Scape 
with the raceme 12-18 inches high, with membranous basal sbeaths, and bearing 
one or more sessile or oblong leaves about the middle, and with 2-8 small distant 
ovate herbaceous sheaths above them. Spike 4—6 in. ; flowers distant ; bracts $ in.long, 
lanceolate, acuminate ; sepals dorsal, 3-nerved, nearly orbicular, lateral 4 in. subacute, 
reflexed; lip elongate, linguiform, obtuse; anther broad, cells distant divergent, 
tubes hardly any ; pollinia shorter than their stout caudicles, glands large orbicular ; 
stigmatic processes 0 ` rostellum very obscure. Capsule (immature) sessile, curved.— 
A remarkable species, in habit unlike any other. The solitary long-petioled radical 
leaf, sometimes distant from the flowering stem, is very peculiar, and closely resembles 
that of Cryptostylis (Zosterostylis, Blume), zeylanica.

* Spur as long the sepals, or longer, or shorter in H. aristata. 
t Leaves scattered along the stem, or radical. (See also 83. H. Gardneri.) 
78. H. bicornuta, Hook. f.; leaves lanceolate or ovate-lanceolate, 
spike long many-fld., bracts equalling or exceeding the ovary, lateral 
sepals linear obtuse, petals as long elliptic, lip tripartite, segments fili- 
form, lateral longer than the sepals recurved over the flower, mid-seg- 
ment shorter, spur longer than the sepals clavate or fusiform incurved.

The Western Guats ; on the Nilghiri and Pulney hills, ascending to 6500 ft. 
Stem 1-2 ft., rather stout. Leaves 2-3 in., sessile, acute or acuminate, 5-1- 
nerved. Spike 6—10 in., rather dense-fld. ; bracts herbaceous, lanceolate, acuminate, 
lower 4-2 in.; sepals } in. long, dorsal oblong obtuse sub 5-nerved, lateral erect at 
length spreading; petals l-nerved; lip with a large concave claw, mid-segment 
variable in length from triangular to linear, straight, obtuse; spur stout ; anther 
minute, cells parallel, tubes 0, pollinia clavate, caudicles short; stigmatic processes 
long, lying in the claw of the lip; rostellum truncate, plicate, concealing the base of 
the cells and pollen glands ?—Blackens when dry. Differs from stenostachya m the 
larger flowers, long side lobes of the lip, and spur. 
79. H. stenostachya, Benth. Fl. Hongk. 362; leaves lanceolate 
acuminate, spike narrow lax- or dense-fid., flowers small, bracts equalling 
or exceeding the ovary, lateral sepals linear obtuse, petals larger than 
the sepals triangular-ovate or oblong fleshy, lip as long as the sepals 3-fid, 
side lobes subulate, midlobe usually shorter broader and obtuse, spur stralg t 
about as long as the ovary. H. peristyloides, Wight Ic. t. 1702. Platan-
