158 CXLVIII. ORCHIDEX. (J. D. Hooker.) [ Habenaria. 
82. H. 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- 
branons, 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. & Sp. Orchid. 300; Thwaites 
Enum, 310 (in part excl. syn.). P. exilis, Wight Ic. t. 1698. 
Kuasta Hints, alt. 4-5000 ft. J. D. H. & T. T. Travancore; on 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 4 in., ovate- 
lanceolate ; flowers distant, } in. diam., greenish; ovary } in., erect; sepals and 
petals membranous, l-nerved, 2 in. long; lip with a retrose spur over the concave 
claw, lateral segments broad at the base sometimes very long and circinnate, spur 
variable; anther minute, cells parallel, tubes 0, pollinia minute of few grains, 
caudicles and glands obscure; stigmatic 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. H. Gardneri, Hook. f.; tall, leaves oblong-lanceolate acute, 
spike narrow many-fld., bracts as long as the ovary, lateral sepals linear- 
oblong faleate 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, Thwaites 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 4 in., ovate-lanceolate, acuminate ; ovary erect, j-3 1.5 
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 ; stigmatic processes clavate; rostellum erect, truncate, 
toothed, plicate, concealing the glands of the pollinia. Capsule } in., erect, fusiform, 
hardly beaked, very shortly pedicelled.— Differs from H. aristata in the large 812° 
robust habit, less membranous leaves with strong nerves, larger flowers and longer 
ovary and capsule. Near H. stenostachya, but the spike and ovaries are muc 
longer, the stem naked below for several inches, and the spur shorter. 
84. H. Stocksii, Hook. f.; rather stout, leaves obovate ox 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 Concan and Mysore, Stocks, Ritchie, &c. 
Stem with spike 6-18 in. Leares more or less clustered towards the midd 
the stem, 4-6 in. long, usually petioled. Spike 3-6 in.; lower bracts often i n. 
long, finely acuminate; ovary L-E in., curved; flowers i in. diam., yellowis i 
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.
