148 CXLVln. ORCHIDE.S. (J. D. Hooker.) [Habenaria. 



51. H. trifurcata, Hook. f. ; leaves petioled elliptic-lanceolate 

 acuminate, spike many-fld., bracts equalling the ovary, sepals subequal 

 ovate-lanceolate acute, petals narrowly linear, lip as long as the sepals 3- 

 partite to near the base segments subulate, spur as long as the ovary or 

 longer slender. 



KHASIA HILLS; at Nowgong (Herb. Calcutt.]. 



Stem 10-12 in., rather slender, leafless below. Leaves 3-4 in., alternate, mem- 

 branous, not margined, upper or sheaths lanceolate. Spike many-fld.; bracts 

 slender, lanceolate; ovary 5 in., slightly curved ; sepals \ in. long, membranous, 

 3-nerved ; petals as long, 1-nerved ; anther oblong, cells contiguous, tubes short 

 divaricate ; stigmatic processes elongate, clavate, adnate to the sides of the lip ; ros- 

 tellum narrow, erect. The petioled scattered leaves and petals distinguish this at 

 once from H.furcifera, and the petals and spurs from fusifera, 



52. H. avana, Hook, f.; leaves linear-lanceolate acuminate, spike 

 many-fld., bracts longer than the flowers, dorsal sepal very broad, lateral 

 oblong acute, petals as long triangular, lip longer than the sepals tripartite 

 from beyond the base, segments linear-subulate lateral incurved, spur as 

 long as the short not beaked ovary. 



BURMA ; at Avu, Mrs. Burney (Herb. Calcutt.). 



Stem 6-10 in. Leaves, lower 2 in., with long tubular sheaths, upper many erect 

 very narrow. Spike dense-fid.; lower bracts f- in.; ovarv j in., curved; sepals 

 rather shorter, dorsal broadly ovate obtuse 5-nerved, lateVal deflexed 3-nerved ; 

 petals 2-nerved ; lip hardly twice as long as the sepals, linear before forking ; anther 

 short, rather broad, tips of cells recurved hardly tubular ; caudicles of pollinia very 

 short, glands large ; stigmatic processes long, clavate, adnate to the lip ; rostellum 

 broad, acute, flat. The specimens are indifferent. 



Bracts large, cucullate. Flowers secund. 



53. K. Heyneana, Lindl. Gen. & Sp. Orchid. 320; stem stout, leaves 

 subimbricate short sheathing acute, bracts cymbiform acuminate sheathing 

 the flowers, sepals subequal obtuse, petals as long narrow, lip equalling 

 the sepals 3-partite side lobes linear obtuse midlobe longer and broader, 

 spur as long as the ovary or shorter straight subclavate. Wight Ic. t. 923, 

 1703-4 ; Dalz. fr Gibs. Bomb. FL 268. H. glabra, A. Rich, in Ann. Sc.

 to 7500 ft. on the Nilghiris. 



Stem 6-10 in. Leaves 1-1^ in., ovate, erect or recurved, rarely scattered and 

 narrower. Spike 2-4 in.; bracts imbricating, lower 1 in. long; ovary J in. , not 

 beaked ; flowers greenish -yellow ; sepals ^ in., thick, nerves obscure, dorsal ovate- 

 oblong, lateral narrower ; petals linear-oblong ; lip thick, variable, midlobe oblong 

 or ovate-lanceolate ; anther short, cells rather spreading, tubes ; caudicles of pol- 

 linia very short stout, glands very close together, large, orbicular ; stigmatic pro- 

 cesses very large, spreading, clavate ; rostellum short, triangular, acute. Turns 

 black in drying. 



54. K. subpubens, A. Rich, in Ann. Sc. Nat. Ser. 2, xv. 75, t. 

 4 C ; leaves linear or linear-oblong scattered, bracts narrowly boat-shaped 

 acuminate, sepals subequal, petals as long falcate, lip spathulate clawed 

 3-fid, as long as the sepals, side lobes linear midlobe broader, spur as long 

 as the ovary acute. H. Candida, Dalz. in Hook. Journ. Sot. ii. (1850), 262 ;
