158 CXLVIII. ORCHIDE^E. (J. D. Hooker.) [Hdbenaria. 



82. K. aristata, Hook. f. ; very slender, leaves 3-5 elliptic-lanceolate 

 membranous, spike very slender lax-fld., bracts shorter than the shortly 

 beaked ovaries, sepals subequal linear obtuse, petals broader oblong mem- 

 branous, lip longer than the sepals 3-partite lateral segments longest 

 filiform or capillary, spur clavate or fusiform equalling or shorter than the 

 sepals. Peristylus aristatus, Lindl. Gen. 8f Sp. Orchid. 300; Thwaites 

 Enum. 310 (in part excl. syn.). P. exilis, Wight Ic. t. 1698. 



KHASIA HILLS, alt. 4-5000 ft. J. D. H. $ T. T. TBAVANCOKE j 011 the Pulney 

 Mts., Wight. CEYLON; at Newera Elia, Thwaites.' 



Stem with spike 18-20 in. Leaves 2-3 in., clustered around the middle of the 

 stem, sessile or subpetioled. Scape with a few narrow sheaths ; bracts -^ in. , ovate- 

 lauceolate ; flowers distant, in. diam., greenish; ovary ^ in., erect; sepals and 

 petals membranous, 1-nerved, i in. long; lip with a retrose spur over the concave 

 claw, lateral segments broad at the base sometimes very long and circinuate, spur 

 variable; anther minute, cells parallel, tubes 0, pollinia minute of few grains, 

 caudicles and glands obscure ; stigniatic processes clavate ; rostellum obscure. 

 Capsule % in., fusiform. The very minute column is so distorted by pressure that I 

 have failed to detect the relations of the rostellum. to the gland of the pollinia. 



83. K. Gardner!, Hook. f. ; tall, leaves oblong-lanceolate acute, 

 spike narrow many-fld., bracts as long as the ovary, lateral sepals linear- 

 oblong falcate obtuse, petals larger broadly oblong obtuse, lip rather 

 longer than the sepals 3-partite lateral segments subulate recurved mid- 

 segment shorter obtuse, spur as long as the sepals incurved tip globose 

 didymous. Peristylus aristatus, T/iwaites Enum. 310 (in part). 



CEYLON, Gardner, Walker-, Adam's Peak, Thwaites (C.P. 3081. Ic. in Herb. 

 Peradeniya, 2373 in Herb. Lindl.). 



Stem with spike 14-30 in., stout or slender, naked below and above except for a 

 few sheaths. Leaves 2-3 in., usually clustered towards the middle of the stem, 

 spreading or suberect, strongly 5-7-nerved beneath, bases sheathing. Spike 6-14 in. , 

 rather stout ; lower bracts ^ in., ovate-lanceolate, acuminate ; ovary erect, - f in. ; 

 sepals in. long and petals spreading, lateral sepals falcate linear obtuse ; lip thick, 

 claw concave; anther small, cells parallel, tubes 0, pollinia pyriform grains large, 

 caudicles and glands obscure j stigmatic processes clavate ; rostellum erect, truncate, 

 toothed, plicate, concealing the glands of the polliuia. Capsule % in., erect, fusiform, 

 hardly beaked, very shortly pedicelled. Differs from H. aristata in the large size, 

 robust habit, less membranous leaves with strong nerves, larger flowers and longer 

 ovary and capsule. Near H. stenostacJiya, but the spike and ovaries are much 

 longer, the stem naked below for several inches, and the spur shorter. 



84. H. Stocksii, SooJc. f. ; rather stout, leaves obovate or elliptic 

 obtuse acute or acuminate, spike strict twisted, flowers secund, bracts 

 longer than the ovaries, lateral sepals linear-oblong, dorsal elliptic, petals 

 larger ovate obtuse fleshy, lip shorter than the sepals obtusely 3-nd, spur 

 as long as the sepals straight or incurved subclavate. 



The CONCAN and MYSORE, Stocks, Ritchie, &c. 



Stem with spike 6-18 in. Leaves more or less clustered towards the middle of 

 the stem, 4-6 in. long, usually petioled. Spike 3-6 in. ; lower bracts often f iu. 

 long, finely acuminate ; ovary -|- in., curved ; flowers ^ in. diam., yellowish ; 

 lateral sepals at length reflexed ; lateral lobes of lip incurved, claw broad concave ; 

 anther minute, cells parallel, pollen clavate ; stigmatic lobes clavate ; rostellum 

 minute, erect, 2-fid. Very like H. Lawii, but spur quite different. 



** Spur much shorter than the sepals, globose or ellipsoid.
