Habenaria.'] CXLVIII. ORCHIDE^E. (J. D. Hooker.) 155 



of Sect. Perisfylus, to which this species is perhaps referable, but the branched 

 rootstock, habit, and habitat induce me to refer it here. 



** ]STo stigmatic processes. 



74. K. arcuata, Hook. f. ; stem very robust leafy, leaves oblong or 

 lanceolate, bracts herbaceous narrow longer than the large flowers, dorsal 

 sepal beaked, petals small linear membranous, lip twice as long as the 

 sepals linear, spur many times longer than the ovary. Platanthera ar- 

 cuata, Lindl. Gen. & Sp. OrcUd. 289. 



WESTERN HIMALAYA; Royle ; Naini Tal, Davidson. 



Stem as thick as the little finger. Leaves 3-4 in., oblong, subacnte, upper 

 lanceolate, bases sheathing. Spike many-fld. ; lower bracts l-l^-in., linear-lanceolate ; 

 ovary 1-| in., hardly beaked, curved ; sepals 1 in. long, dorsal cucullate, lateral larger, 

 oblong, obtuse, 3-nerved, deflexed ; petals very narrow, 1-nerved ; lip large, linear, 

 with rounded shoulders at the b tse, puberulous, sides reflexed, spur 2-2| in., in- 

 curved, acute; anther large, broad, cells divergent, tubes erect; pollinia with stout, 

 short caudicles, glands very large, ovate ; rostellum broad, flat, acute. A very 

 remarkable species, with the lip of Hologlossa, but anther of the larger Trimero- 

 glosscB. I have seen but one specimen from Col. Davidson, and a rude tracing in 

 Herb. Lindl.. of Royle's plant. 



75. K. sikkimensis. Hook. f. ; stem stout leafy, spike elongate lax- 

 fid., bracts herbaceous longer than the large flowers, petals as large as the 

 sepals triangular-lanceolate, lip as long as the sepals linear, spur rather 



onger than the ovary very stout obtuse strongly incurved. 



SIKKIM HIMALAYA ; on Sinchal, alt. 8-9000 ft., Thomson. 



Stem with spike 10-12 in. Leaves 3-4 in., narrowly oblong. Spike 3-4 in.; 

 bracts lanceolate, acute, lower 1^ in., spreading and reflexed ; ovary \ in., strongly 

 curved, hardly beaked ; sepals 3-nerved, green, dorsal broadly ovate obtuse rather 

 shorter than the oblong-lanceolate acuminate spreading lateral; lip linear; anther 

 broad, cells narrow, distant, tubes short ; pollinia rather shorter than their stout 

 caudicles, glands small ; rostellurn obscure, very broadly triangular. Closely allied 

 to H. acuminata, but flowers much larger, and there are no stigmatic processes or 

 rostellum. The broad anthers and its cells are those of H. arcwata. Only one 

 specimen seen. 



76. K. concinna. Hook. f. Ic. Plant, ined. ; small, stem many-leaved, 

 leaves small sessile erect ovate or oblong, spike many-fld., bracts longer than 

 the small flowers herbaceous, lateral sepals linear longer and much narrower 

 than the dorsal and petals, lip linear from a broad base as long as the 

 sepals, spur as long as the ovary slender incurved acute. 



KHASIA HILLS ; at Kala-pane, ait. 5000 ft., J. T>. H. fy T. T. ; Clarice. 



Root of thick tuberous fibres. Stem with ppike 4-8 in. Leaves almost imbrica- 

 ting, amplexicaul, lower 1-1^ in. obtuse, upper gradually smaller acute ; spike 2-4 

 in., rather dense-fld. ; bracts in., ovate-lanceolate, acute; ovary ^ in., suberect ; 

 dorsal sepals 3-nerved, ovate, obtuse ; lateral ^ in. long, reflexed, obtuse, 1-nerved ; 

 petals as long as the dorsal sepal, 1-3-nerved ; lip narrow ; anther large, cells distant, 

 bases slightly divergent, tubes ; pollinia as long as their caudicles, glands small ; 

 rostellum triangular. The habit is that of Sect. Peristylus. 



77. XX. zosterostyloides, Hook. f. ; radical leaves long-petioled 

 elliptic acute, cauline sessile ovate-cordate amplexicaul, racemes long 

 sparse-fld., bracts as long as the ovary, lateral sepals linear-oblong 

 obtuse rather longer than the rounded ovate dorsal, petals as large as 

 the dorsal sepal triangular-ovate, lip linear as long as the sepals, spur as 

 long as the ovary slender acute.
