t Stem leafy, leaves scattered or subimbricate. 



85. K. brevlloba, SooJs.f. ; slender, leaves oblong-lanceolate acumi- 

 nate, spike short dense-fid., bracts about equalling the ovary, lateral sepals 

 lanceolate, petals broadly^ oblong, lip as long as the sepals oboordate sub- 

 flabellif orm, spur minute inflated incurved. Pefistylus brevilobus, Thwaites 

 Enum. 311. 



Ceilon ; near Ratnapoora, Thwaites. 



Stem with spike 10-18 in., naked below. Leaves 2-3 by f-f in., basea sheathing, 

 nerves very slender. Spilee (young) 1 in. ; bracts lanceolate, finely acuminate ; 

 ovary ^ in. ; lateral sepals linear-lanceolate, subacute, 1-nerved ; petals oblong, 

 obtuse, 3-nerved; lip sessile at the base of the column ; anther oblong, truncate, 

 cells parallel, tubes ; stigmatic processes ; rostellum 3-fid, conceiiling the small 

 polliniar glands. — A very anomalous species, the flowers are too young for satis- 

 factory analysis. Thwaites describes the lip as having a minute midlobe. 



86. Hi xnalabarica^ Soolc. f.; stem leafy, leaves many ovate or 

 lanceolate acuminate upper passing into bracts longer than the flowers, 

 spikes many-fld., ovary very short, lateral sepals linear, petals obliquely 

 ovate-oblong obtuse, lip as long as the sepals deeply trifid, lateral seg- 

 ments subulate recurved, mid one straight, spur a small globose didymous 

 or ellipsoid sac. Peristylus brachyphyllus, A. Rich, in Ann. Sc. Nat. Ser. 

 2, XV. 70, t. 2 A. 



NiLGHiEl, and Bababudan Hills in Canaea, Hei/ne, Perfottet, Stocks. 



Stem rather stout, 6-12 in. Leaves 1-2^ in., bases sheathing, nerves very 

 slender. Spike 2—4 in., rather dense-fld. ; bracts herbaceous, lower -i-J in. or 

 longer, often twice as long as the flowers, ovate-lanceolate, acuminate, sheathing ,- 

 ovary ^ in.; lateral sepals as long, erect or spreadiug, 1-nerved, apiculate below the 

 tip, dorsal elliptic obtuse faintly 3-nerved; base of lip 3-lobed above the concave 

 claw, contracted at the base of the segments ; spur incurved or not ; anther-cells 

 parallel, glands of pollinia concealed by the 3-fid rostellum; stigmatic processes 

 clavate. — Habit of R. peristyloides & concinna. 



87. K. tOTta, Sooh. f. ; small, slender, subbasal leaves linear-lanceo- 

 late upper passing into narrow sheaths, spike very slender lax-fld. twisted, 

 bracts longer than the very small secund flowers, lateral sepals linear 

 obtase, petals linear-oblong, lip equalling the sepals 3-cleft beyond the 

 middle, lobes short obtuse lateral spreading or incurved midlobe straight, 

 spur a minute sao. Peristylus spiralis, A. Uich. in Ann. 8c. Nat. Ser. 2, 

 XV. 69, t. 2 B ; Wight Ic. t. 1696.

Stem with the spike 6-18 in., often flexuous. Leaves 1-2^ in., obtuse acute or 

 acuminate, nerveless, passing into the sheaths of the scape. S}>ilce 2^ in., racliis 

 often flexuous ; bracts J- J in., lanceolate, acuminate ; flowers decurved, greenish 

 white ; lateral sepals reflexed, J^-J in. long, dorsal linear-oblong obtuse ; lip very 

 variable, fleshy, broader or narrower than long, base truncate above the short 

 concave claw; anther minute, cells parallel; stigmatic processes clavate; ros- 

 tellum between the cells, 3-fid. — The Ceylon plant has larger flowers than the 

 Peninsular.
