* Stigmatio processes large. 



-f- Stem leafy upwards. 



67. K. latilabris, Hook. f. ; ]«aves sessile ovate or oblong acumi- 

 nate, spike many-fld., bracts green longer than the ovary, dorsal sepal 

 broadest, lateral broadly ovate, petals dimidiate-ovate or broadly ovate, 

 lip linear or lanceolate, spur ilexuous longer than the curved beaked ovary.

Tempebate Himalaya ; from Kashmir, alt. 5-10,000 ft., to Sikkim, 

 alt. 7-12,000 ft. Oentkal India, Hope (Herb. Clarke). 



Stem 6-18 in., stout or slender, leafy. Leaves 3-5 in., usually sheathing. 

 Spike 3-10 in., lax-fld. ; bracts ovate-lanceolate, lower leafy ; ovary J-^ in., curved ; 

 flowers yellow-green, ^-J in. diam. or more ; sepals 3-5-nerved, glabrous or ciliolate, 

 lateral spreading or deflexed, dorsal orbicular concave ; petals as long as the lateral 

 sepals, variable in shape, fleshy, lower base gibbous ; spur stout or slender, often 

 involute and upcurved ; anther-cells contiguous, tubes j caudicles of pollinia very 

 short, glands small ; stigmatio processes large, subglobose ; rostellum short, tri- 

 angular, obtuse. CapsVile ^ in., sessile, fusiform, shortly beaked, more or less curved 

 or twisted. — A very common and variable species in the Himalaya. 



68. K. stenantha, HooJc.f. ; leaves many sessile oblong, spike many- 

 fld., bracts green much longer than the flowers, dorsal sepal oblong, lateral 

 linear deflexed, petals erect as long as the sepals linear, lip linear obtuse, 

 spur flexuous longer than the straight obtuse ovary. 



Tempeeate Himalaya ; Sikkim, alt. 8-12,000 ft., J. D. B., Clarke. 



Very near to B.. latilabris, differing in the form of the lateral sepals and petals, 

 which are very narrow, and straight ; and the former being sharply deflexed, whilst 

 the latter are erect ; the flower hence looks as if laterally compressed. The lip 

 also is very narrow, but more so than in forms of aonminata, with which stenantha 

 agrees in the column, anthers, pollinia, stigma and rostellum. 



69. K. densa. Wall, in Lindl. Oen. & Sp. Orchid. 326; tall, stout, 

 leaves many ovate or oblong acuminate base sheathing, spike very long 

 narrow stout, bracts sheathing and exceeding the very short ovaries, flowers 

 very small, sepals obtuse pubemlous, lip linear obtuse as long as the sepals, 

 spur clavate shorter than the ovary. Platanthera densa, Lindl. in Wall. 

 Cat. 7046. P. clavigera, Lindl. Gen. & Sp. Orchid. 289. 



Temperate Himalaya ; from Simla to Sikkim, alt. 5-9000 ft. 



Stem 1-3 ft. usually much stouter than in any form of H'. acMm»!wii(z or its allies. 

 Leaves 3-5 by 1-2 in. Spike 8-14 in., rather dense-fld. ; rachis stout; bracts 

 ■^1 in., finely acuminate; ovary ^ in., stout, curved, shortly beaked; flowers erect, 

 iiu. diam. ; sepals subequal, thick, 3 -nerved; petals nearly as long, obliquely ovate 

 or narrower, obtuse, fleshy ; lip with a tooth at the mouth of the spur ; anther short, 

 broad, cells parallel, tubes ; pollinia subglobose, almost sessile on the large orbicular 

 gland ; stigmatio processes large, shortly clavate ; rostellum small, erect.— Varies 

 greatly in size; a Wallichian specimen from Nepal is 3 ft. high, with leaves 

 6 by 2 in., and a fruiting spike nearly 18 in. long. The most distinct species of its 

 group.
