 large rounded. Thwaites JEnum. 2^5 ; Ridley in Journ. Linn. Soc. xxii.

TRAVANCORE ; 011 the Pulney Mts., Wight. CEYLON, Macrae; elevated parts 

 of the Central Province, T/iwaites, &c. 



Habit and foliage of L. Walkerice, but leaves always extremely unequal at the 

 base, with one side rounded or auric-led and the other acutn, margins smooth or 

 crisped ; scapes taller, racemes longer, and flowers very much larger and dark vinous 

 purple, the dorsal sepal f of an inch long. L. livida, Lindl., included under atro- 

 purpHfrea by Ridley, is a very different plant (see end of genus). Lindley has fastened 

 on the same sheet with this in his Herbarium a specimen of -L. Walkerice with the 

 habitat " Kliasia, Lobb,". which I doubt not i's an error for the Nilghiri Hills, where 

 Lobb also collected. 



30. Xi. br achy glottis, Reichb.f. in Trimen Cat. PL Ceylon; small, 

 leaves 2 alternate petioled or the upper sessile ovate or ovate-cordate 

 acuminate, bracts ovate concave, flowers very small, sepals obtuse 3- 

 nerved, lateral broadly ovate-oblong, dorsal much longer lanceolate, lip 

 short transversely oblong with obscure basal thickenings, column short 

 straight truncate. Ridley in Journ. Linn. Soc. xxii. 275. 



CEYLON ; Central Province, alt. 50CO ft. ; on Wuteakelle Hill, Thwaites. 



Stem 23 in., rather slender, not pseudobulbous. Leaves 1| 2^ in., 5-nerved. 

 Scape and raceme 2 3 in. ; bracts f in., persistent, concave, not reflexed ; pedicels 

 i in. ; flowers about \ in. across, red-purple. 



31. Xi. biloba, Wight Ic. vi. 3633; small, leaves 2-3 petioled ovate 

 acute undulate, flowers small, bracts ^ in. lanceolate, sepals oblong-lan- 

 ceolate acute, lateral hardly falcate, lip cuneate straight shortly clawed 

 2-lobed 2-tubercled, lobes oblong or lanceolate obtuse, column slender 

 curved, wings small obtuse. Walp. Ann. \i. 218; Ridley in Jo-urn. Linn.

NILGHIRI HILLS ; at Ootacamund, Wight,. 



Whole plant purplish. Stem f in., pseudobulb ^ in. Leaves 1 by -3 j in., green 

 or purple. Scape li in. ; flowers very dark purple. Wight likens it to L. atropur- 

 pitrea, from which the 2-lobed lip distinguishes it. 



Sect. II. CORIIFOLI^E. Leaves jointed at the base upon the leaf-sheath 

 or on a pseudobulb, usually coriaceous. 



* Leaf usually solitary on the pssulobulb. Lip as long as the lateral 

 sepals or nearly so (when spread out). 



t Sepals %-nerved (obscurely in L. Prainii).
