9:to 19:5 mm. across, deflexed in bud; floral bracts lanceolate, acuminate; the lower ones 
longer and the upper shorter than the curved beaked ovary. Sepals green, pubescent, 
their edges minutely ciliolate; the dorsal erect, broadly ovate or sub-orbicular, concave; 
the lateral pair larger, deflexed, obliquely ovate, obtuse. Petals erect, yellow, thick, 
obliquely triangular from a broad base, their apices curving inwards and forming a hood 
with the dorsal sepal, turning black when dried. Zip yellow, longer than the lateral 
sepals; anterior portion thick and strap-shaped, deflexed abruptly from the end of the 
wider channelled claw; spur much longer than the ovary, curving upwards, yellowish- 
green. Anther-cells distant, parallel; pollinia obliquely pyriform, bipartite ; caudicles short, 
curved, each attached to a small bipartite gland. Staminodes elongate. Stigmatic 
precesses oblong, nearly parallel, situated below the opening to the spur; rostellum 
triangular, Н. Jlatilabris Hook, f. Fl. Br. Ind. vi, 153 (іп part). Platanthera

Throughout the Western Himalaya from Hazára to Kumaon at elevations between 
6,000 and 10,000 feet. It is the most abundant terrestrial orchid on the Simla and 
Mussoorie ranges, and is very often found in company with Satyrium nepalense on 
open hillsides. It commences to flower during July, but always a little later than

The upturned position of the spur in Z7. Edgeworthii may be explained by the fact that the 
flowers, when in bud, are deflexed, and the spurs are then directed upwards. The flowers, as they 
begin to open, curve up and become sub-erect, but by this time the elongated spurs have not 
sufficient space in the crowded raceme in which to alter their position.

Tubers fusiform. Siem 2 to 45 dm., with a few loose sheaths near the base, 
of which the upper ones are often sub-foliaceous. Leaves scattered, three to five, 5 
to 10 em. long, elliptic-oblong, acute or acuminate, tapering into the broad sheaths; 
bracts below the raceme about 2:5 cm, long, lanceolate, acuminate, Spike 7:5 to 13 
cm., laxly flowered. Flowers 12 to 14 mm. long (from the base to the tip of the 
dorsal sepal’, the sepals dark green and the petals and lip yellowish-green; floral 
bract lanceolate, acuminate, those of the lower flowers longer than the curved beaked 
ovary, of the upper flowers shorter. Sepals unequal, their edges ciliolate; dorsal 
erect, 4 mm, long, broadly ovate or sub-orbicular, concave; the lateral pair reflexed, 
5 mm. long, obliquely ovate, obtuse. Petals slightly longer than the lateral sepals, 
spreading, lanceolate or linear from a broad triangular base, gibbous on their outer 
edges near the base. Lip rather longer than the petals, deflexed from the apex of 
the short broad claw, sub-terete or linear-oblong with reflexed edges, tapering slightly 
to the apex; spur about 15 mm. long, slender, curved but not upturned as іп Z. 
Edgeworthi, cylindric or compressed and with the apex often bifid or trifid. Column 
short. Anther-cells parallel, distant, each with a rounded rugulose staminode on its 
outer side near the base; tubes short, curved forwards; pollinia obliquely pyriform, 
almost bipartite, tapering into the short stout caudicles; glands small, elliptic. Stigmas
