Not uncommon on the Western Himalaya from Dalhousie to Kumaon at elevations 
between 5,000 and 9,000 feet; specimens have, however, been gathered by Mr, C. W. 
Hope as low down as Dehra Dun. It becomes more abundant eastwards, but in no 
portion of the area is it as plentiful as И. Edgeworthii, which extends as far west as 
Hazara. Н. latilabris is more of a shade-loving plant, and is very often found as an 
epiphyte on the trunks of trees, Flowers during July and August. It extends eustwards 
to Nepal, Sikkim and E. Tibet. 
In the living state this species can be easily distinguished from JH. Edgeworth by the nearly 
uniform greenish tint of its flowers, the spreading petals and by the shorter and much more slender 
spur, which is usually not curved upwards.

21. HABENARIA DENSA Wall. in Lindl. Gen, and Sp. 826, 
Zubers oblong, Stem stout, З to 7°5 dm., with a few loose blunt sheaths at its base, 
Leaves many, scattered, 6 to 10 cm. long, ovate or oblong, acuminate, tapering very 
little to the long sheath, diminishing in size upwards. Spike 2 to 3:5 dm. long, many- 
flowered, rachis stout. Flowers crowded, erect, 7 mm. across, green; floral bract longer 
than the short curved slender-beaked ovary, lanceolate, acuminate, the edges ciliolate. 
Sepals sub-equal, elliptic-oblong, obtuse, thick, ciliolate, 3-nerved; dorsal erect, concave ; 
lateral pair narrower, reflexed. Petals nearly as long as the sepals, obliquely elliptic- 
oblong, obtuse, fleshy. Lip equalling the sepals, linear, obtuse, with а transverse callus 
at its base close to the columu; spur half as long as the ovary, clavate, pendulous, 
compressed laterally. Column short, broad. Anther-cells distant, parallel, without tubes; 
pollinia broadly elliptic, caudicles short; glands discoid, guarding the entrance to the spur. 
Staminodes large, each consisting of two united elongate processes, the upper pair rugulose 
and parallel to the sides of the anther-cells; lower pair smooth, their apices converging 
inwards below the stigmas and almost meeting over the base of the lip. Stigmas two, 
small, sub-orbicular, placed between the polliniar glands and the staminodes. Hook,
