156 CXLVIII. ORCHIUE^E. (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 sheaths, and bearing 

 one pr 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 ^ in. subacute, 

 reflexed; lip elongate, liuguiform, obtuse; anther broad, cells distant divergent, 

 tubes hardly any ; pollinia shorter than their stout caudicles, glands large orbicular ; 

 stigmatic processes ; rostelluin very obscure. Capsule (immature) sessile, curved. 

 A remarkable species, in habit unlike any other. The solitary loug-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. 



f* Leaves scattered along the stem, or radical. (See also 83. H. Gardner!.) 



78. H. foicornuta, 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 GHATS ; on the Nilghiri and Pulney hills, ascending to 6500 ft. 



Stem 1-2 ft., rather stout. Leaves 2-3 in., sessile, acute or acuminate, 5-7- 

 nerved. Spike 6-10 in., rather dense-fid. ; bracts herbaceous, lanceolate, acuminate, 

 lower -3| in. ; sepals % in. long, dorsal oblong obtuse sub 5-nerved, lateral erect at 

 length spreading; petals 1 -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 in the 

 larger flowers, long side lobes of the lip, and spur. 



79. H. stenostachya, Senth. Fl. Hongk. 362 ; leaves lanceolate 

 acuminate, spike narrow lax- or dense-fld., 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 straight 

 about as long as the ovary. H. peristyloides, Wight Ic. 1. 1702. Platan-

SIKKIM HIMALAYA, King (Herb. Calcutt.}, the KHASIA HILLS, TENASSEEIM, 

 and the DECCAN PENINSULA, from the Concan Southward. DISTRIB. China. 



Stem with the spike 6-30 in., usually slender, with many small sheaths above the 

 leaves. Leaves 14 in., sometimes all subradical, erect, buses sheathing, 5 7-nerved. 

 Spike 3-5 in. ; flowers small, erect, greenish yellow or white, about ^ in. diam. ; 

 bracts ^-^ in., broadly ovate-lanceolate, finely acuminate ; ovary i in.; sepals in. 

 loug, subequal, concave, lateral suberect, at length spreading, nerve very thick, 

 produced into a point under the apex of the sepal; lip with a large excavate base, 

 very variable in the length of the lobes, lateral spreading or recurved ; anther
