Habenaria. CXLVIII. OKCHIDE^:. (J. D. Hooker.) 147 



Platanthera acuifera, Lindl. in Wall. Cat. 7045. P. rostrata, Lindl. in 

 Wall. Cat. 7051 B. 



KHASIA HILLS, alt. 4-5000 ft., common. NAGA HILLS, Prain. TAVOY, 

 Wallich.* DISTBIB. China. 



Stem 10-18 in., flexuous. Leaves 2-4 by -| in., erect, base sheathing, upper and 

 linear lanceolate ciliolate bracts very finely acuminate ; ovary - f in., rugose, beaked 

 for half its length ; flowers golden, -| in. diam. ; dorsal sepal strongly 3- lateral 5- 

 nerved ; petals 1-nerved; margins of midlobe of lip revolute, spur slightly clavate ; 

 anther large, apiculate, tubes long erect, caudicles of pollinia long very slender, glands 

 minute ; stigniatic processes clavate, incurved. Lindley errs in describing the leaves 

 as all radical, and in giving Ceylon as a habitat. 



48. K. chlorina, Eeickb. f. in Trans. Linn. Soc. xxx. 140; habit 

 and character of H. acuifera, but rather stouter, leaves broader, spike 

 longer, sepals and petals 3-nerved, side lobes of lip large and spur incurved 

 below the middle with a large clavate ellipsoid tip. 



TENASSERIM j at Moulmein, Lobby Parish. SHAN STATES, alt. 4400 ft., 

 Collett. 



Leaves -i-f in. broad. Spike 2-3 in. long ; flowers at first yellow-green, then 

 spotted with brown, at last brown. Probably a form of H. acuifera, but besides the 

 above difference the flowers are smaller. 



** Tubes of anther-cells short. 



t Stem leafy upwards. 



Bracts lanceolate, acuminate. Flowers not or hardly secund. 



49. K. elliptica, Wight Ic. t. 1706 ; leaves all linear-oblong or 

 lanceolate acuminate narrowly margined, spike many-fld., bracts longer 

 than or equalling the ovaries, dorsal sepal shorter than the broadly oblong 

 obtuse lateral, petals triangular-ovate ciliolate, lip as long as the sepals 

 trifid beyond the middle lobes oblong obtuse, spur stout equalling the 

 shortly beaked incurved ovary. 



IRAVANCORE; on the Pulney Mts., Wight. 



Stem 12-18 in., rather stout. Leaves 2-3 by ^-f in., upper short sheathing, 

 erect or incurved. Spike 2-4 in., cylindric ; bracts finely acuminate ; flowers 

 greenish-white, about gin. diam. ; perianth thick subpuberulous ; sepals 3-nerved, 

 dorsal ciliolate almost orbicular, lateral ovate-oblong ; petals shorter, fleshy ; lobes 

 of lip parallel ; anther broad, cells distant divaricate, tubes short; pollinia longer 

 than their stout caudicles, glands small j stigniatic processes large, clavate ; rostellum 

 broad, triangular. 



50. XX. fusifera, Hook. f. ; leaves oblong acute narrowly margined, 

 spike many-fld., bracts longer than the ovary, dorsal sepal suborbicular 

 nearly as long as but broader than the oblong obtuse lateral, petals larger 

 than the sepals triangular-ovate, lip larger than the sepals 3-partite to the 

 base, side segments filiform longer than the linear mid segment, spur 

 shorter than the curved ovary fusiform with a short narrow neck. 



TRAVANCORE ; on the Annamallay Hills, Beddome (in Herb. CalcuU.). 



Habit of H. elliptica, but very different in the shorter not beaked ovary, larger 

 dorsal sepal, and petals, 3-partite lip, and spur; flowers yellow ; anther broad, 

 cells divaricate, tubes short ; pollinia clavate, caudicles short, glands small ; stigmatic 

 processes clavate, incurved, adnate to the mouth of the spur. I have seen only one 

 specimen.
