580 G. King & R. Pantling — Neiv Indo-Malayan Orchids. [No. 3, 



and '25 to 35 in. broad. Inflorescence slender, decurved, about 4*5 in. 

 long ; the peduncle short and ebracteate, adnate to the uppermost and 

 reduced leaf ; the raceme many-flowered. Flowers about '05 in. long, 

 verticillate ; floral bract lanceolate, shorter than the ovary. Sepals 

 subequal, ovate, acute, spreading. Petals linear-oblong, acute, spread- 

 ing. Lip larger than the sepals and petals, broadly oblong in general 

 outline, 3-lobed ; the basal lobes rounded ; apical lobe sub-rotund, 

 somewhat contracted at the base, the apex broad and erose, otherwise 

 entire. 



Perak : Scortechini No. 1516 (with drawing). 



A species allied to 0. demissa, Lindl. and to 0. micrantha, King and 

 Pantling; but differing from both in having linear-oblong acute petals, 

 and also in the shape of the basal lobes of the lip which in 0. demissa are 

 blunt and erose, in 0. micrantha broad rounded and subentire, while in 

 this they are oblong and entire. The apical lobe of the lip of this is 

 also slightly different from that of the other two, being in outline more 

 orbicular, and erose only at the apex. The leaves of this are moreover 

 longer than those of 0. micrantha, while the raceme differs from that 

 of 0. demissa in not being truncate. 



Obeeonia Proudlockii, n. spec. Whole plant six inches in height, 

 or less. Stems very short, tufted. Leaves ensiform, acute, not falcate 

 or only slightly so, fleshy but with thin edges, 1 to 25 in. long and 

 *25 to "5 in. broad. Inflorescence about twice as long as the leaves, erect 

 below but slightly decurved above ; the peduncle about as long as the 

 spike, fleshy, 2-winged, ebracteate ; rachis of the spike thick, fleshy, 

 terete. Floivers numerous, reddish-brown, *05 in. long, sunk singly in 

 pits in the rachis, the perianth adpressed to its surface; floral bract 

 covering the flower-buds, longer than the sub-sessile ovary, ovate- 

 rotund, fleshy in the middle but with broad membranous laciniate 

 margins. Sepals reflexed, ovate, acute, entire. Petals ovate-lanceolate, 

 entire, reflexed on the ovary like the sepals. Lip broader but hardly 

 longer than the sepals, convex, sub-quadrate ; the base truncate and 

 with an obscure rounded auricle at each extremity, slightly narrowed to 

 the broad sub-truncate apex, the margins slightly and obscurely erose 

 but not lobed ; nectary small, elliptic-rotund, deep, situated at the base 

 just under the column. 



Nilgiri Hills ; near Gudalur, Mr. R. L. Proudlock ; in flower in 

 September. 



A species allied to 0. pachyrachis, Reichb. fil., and 0. orbicularis, 

 Hook, fil., and still more closely to the Sikhim species 0. pachyphylla, 

 K. & P. ; but differing from them all by its reflexed sepals and 

 differently shaped lip.
