82. IZ. aristata, Sooh. f. ; very slender, leaves 3-5 elliptic-lanceolate 

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

 beaked ovaries, sepals subeqnal 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. Peristylua aristatns, lAndl. Gen. 8f Sp. Orchid. 300; Thwaites

 Mts., Wight. Cbilon ; at Nevvera Elia, Triioaites.' 



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- 

 lanceolate ; flowers distant, i; in. diam., greenish ; ovary J in., erect ; sepals and 

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

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

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

 caudicles and glands obscure ; ■ stigmatic processes clavate ; rostellum obscure. 

 Capsule J 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!, Sooh. f. ; tall, leaves oblong-lanoeolate acute, 

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

 oblong falcate obtuse, petals larger broadly oblong obtuse, b'p rather 

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

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

Cetloh", Gardner, Walker; Adam's Peak, Thwaites (C.P. 3081. Jc. in Serh. 

 Feradeniya, 2378 in Serh. Iiindl.). 



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

 few sheaths. I/eaves 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 J in., ovate-lanceolate, acuminate ; ovary erect, J— f in. ; 

 sepals J 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 ; stigmatic processes clavate; rostellum erect, truncate, 

 tootbed, plicate, concealing the glands of the pollinia. Capsule J in., erect, fusiform, 

 hardly beaked, very shortly pedicelled. — Differs from JSC. arislata in the large size, 

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

 ovary and capsule. Near S. sienostachyaj but the spike and ovaries are much 

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



84. K. Stocksii, Sooh. 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-fid, spur 

 as long as the sepals straight or incurved subclavate. 



The CoNOAJr and Mysobe, Stocks, Ritchie, &c. 



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

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

 long, finely acuminate ; ovary J-J in., curvedj flowers i 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 S. Lawii, but spur quite different. 



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