and wider-spreading than the dorsal, and keeled. Petals linear, trun- 

 cate, shorter than the sepals, entire, pale yellow and transparent 

 like the sepals. Lip reddish broAvn, with broad reniform base having 

 a lateral sinus and a short convergent horn at each side at its anterior 

 end : the apical lobe broadly obloug, deeply bifid, the lobes lanceolate 

 and slightly convergent, and the sinus narrow, not triangular and with 

 a concave emarginate apex. Stigma concave. 



Bhotan : at Guru-bathan, at an elevation of about 1,500 feet; in 

 flower in February. 



A very distinct species. 



Oberonia lobulata, n. spec. Acaulescent, not tufted. Leaves 

 about four, large, oblong, sub-acute, 1*25 to 3 in. long, and "4 to *5 in. 

 broad. Raceme 4 in. long, on a winged ebracteate peduncle about 

 half as long, much decurved. Flowers distant, minute, green. Bracts 

 broadly oblong, tbe apex convex and minutely erose equalling and 

 sheathing the sessile ovary. Sepals ovate, acute, entire, reflexed ; 

 the petals similar but narrower. Lip broadly triangular with irregu- 

 larly erose margins, the apex with a broad shallow sinus and two short 

 blunt lobes. Stigma convex ? 



Sikkim : in the valley of the Teesta, at an elevation of about 1,000 

 feet ; in flower in October. 



Collected only once. A remarkable species with the pollinia en- 

 cased within the anther cells and not free as is usually the case in the 

 genus Oberonia. 



Oberonia Prainiana, n. spec. Acaulescent, and slightly tufted 

 Leaves very fleshy, falcate, sub-acute, '5 to *75 in. long, and "25 in 

 broad. Raceme slender, many times longer than the leaves, erect, 4 in. 

 long : stalk of the raceme attached to the uppermost leaf, minutely 

 bracteolate, filiform, about 1 in, long. Flowers of a warm brown colour, 

 verticillate, very minute. Bract oblong, sub-entire, equal to and em- 

 bracing the stout sessile ovary. Sepals oblong, blunt, all much re- 

 volute. Petals elliptic-lanceolate, spreading, deeply serrate. Lip tri- 

 angular-oblong with a circular nectar-bearing pit near its base and 

 under the column, the apex blunt, the margins deeply erose-dentate. 

 Pollinia 2 pairs, orange-coloured. 



Sikkim: in the Teesta Valley, at an elevation of about 1,000 feet ; 

 in flower in July. 



A very distinct species remarkable or the great length of the 

 slender inflorescence in proportion to the leaves, and for its unlobed but 

 deeply erose dentate lip.
