Habenaria.'] CXLVIII. ORCHIDE^;. (J. D. Hooker.) 151 



Dalz. in Hook. Journ. Bot. ii. (1850), 263; Dalz. Sf Gibs. Bomb. Fl. 269 (excl. 

 syn.\ The Deccan Peninsula ; Malwan, Dalzell, &c. 



61. H. khasiana, HooTc.f. ; scapigerous, leaves linear not margined, 

 scape slender, raceme elongate, bracts much shorter than the ovary, sepals 

 3-nerved, dorsal nearly as long as the rather narrower lateral, petals as 

 long ovate-lanceolate, lip much longer than the sepals, side segments much 

 the longest filiform, spur as long as the beaked ovary rather stout slightly 

 incurved. H. graminea, Lindl. Gen. fy Sp- Orchid. 318 (not of Sprengel). 

 Platanthera linifolia, Lindl. in Wall. Cat. 7041 (the Silhet plant}. 



KHASIA HILLS ; in grassy places, alt. 4-5000 ft., common. 



Leaves 3-4 by -J | in., acute or acuminate. Scape with elongate raceme 8-12 in. ; 

 sheaths very few and bracts lanceolate ; ovaries f in., suberect, curved, shortly 

 pedicelled and beaked ; flowers sweet-scented, yellow, narrow ; the strictly deflexed 

 lateral sepals and erect dorsal sepal are in one line, i in. long; anther broad, cells sub- 

 parallel, tubes short; caudicles of pollinia short stout, gland rather large ; stigmatic 

 processes clavate, aduate to the mouth of the spur ; rostellum very short, broad. 

 Capside 1 in., subsessile, fusiform, not beaked.- Very near H. viridiflora, from which 

 the narrower leaves, shorter pedicels, subequal sepals, of which the dorsal is narrower 

 and erect, arid stout spur distinguish this. 



62. H. ditricha, SooTc.f.-, scapigerous, leaves linear acute not mar- 

 gined, spike few-fid., bracts as long as the ovary, sepals 1-nerved dorsal 

 broadly ovate as long as the lanceolate acute lateral, petals as long ovate- 

 lanceolate acute, lip much longer than the sepals 3-partite, side segments 

 capillary, spur longer than the beaked curved ovary slender incurved. 



TENASSERLM ; at Moulmein, Lobb. 



Leaves as in H. khasiana. Scape with few-fid, raceme 2-4 in. ; sheaths few, 

 membranous; bracts -\ in., ovate-lanceolate ; flowers few, % in. broad ; ovary i in., 

 sessile, curved ; dorsal sepal obtuse, obscurely 5-nerved ; mid segment of lip shorter 

 than the lateral; spur hardly thickened at the tip; anther-cells divaricate, tubes 

 short ; pollinia and stigmatic processes as in H. khasiana. Very near H. khasiana, 

 but the scape is very short, the bracts different, the ovary shorter, and the flowers 

 smaller. Lobb's specimens have all short scapes. 



tff Leaves 2, rarely 3, radical or opposite on the stem, sessile, broadly 

 ovate-cordate or oblong. 



63. K. crassifolia, A. Rich, in Ann. Sc. Nat. Ser. 2, xv.72, t. 3 C ; 

 leaves radical orbicular or broadly ovate-cordate margined fleshy, raceme 

 many-fid,, bracts large exceeding the ovary, sepals and petals short broad, 

 lip subequally 3-fid hardly longer than the sepals, lobes linear-oblong 

 obtuse, spur equalling the beaked ovary. H. brachyphylla, Reichb. f. in 

 Trans. Linn. tioc. Ser. 2, iii. 113. Platanthera brachyphylla, Lindl. Gen. 

 $ Sp. Orchid. 293 ; Wight Ic. t. 1694 ; Dalz. & Gibs. Bomb. Fl. 269. 



The DECCAN PENINSULA; from the Concan to the Nilghiris, common. 



Leaves 2-3, 1-1} in. diam. Scape 6-12 in,, stout ; sheaths many, finely acuminate. 

 Spike 6-8 in., narrow; bracts ovate-lanceolate, sheathing; flowers in. diam., 

 greenish-white, rather fleshy ; sepals 3-nerved ; petals 1-nerved ; side lobes of lip 

 hardly spreading ; bases of anther-cells distant, tubes very short spreading ; stig- 

 matic processes short; rostellum small, erect. The Khasian habitat taken by 

 Keichenbach from Lindley's Herbarium is an error. 



64. K. diphylla, Dalz. in JlooTc. Journ. Sot. ii. (1850) 262 ; leaves 

 radical orbicular cordate margined, raceme many-fid., bracts much shorter
