TENASSEKIM ; at Mergui, Parish. 



Leaves 4-5 by 1-1^ in., not margined, subpetioled. Scape as long ; sheath sub- 

 solitary ; bracts much shorter than the filiform straight beaked pedicelled ovary 

 which is 1^ in. long ; sepals 4- in. long ; tubes of anther-cells very long, slender ; 

 stigmatic processes short. Habit of Diplomeris . 



ft Lateral sepals curved or nearly straight, nerves straight or moderately 

 arched. 



42. XX. pterocarpa, Thwaites Enum. 309 ; stem leafy, leaves long 

 linear -lanceolate, bracts equalling the ovary, flowers few very large, dorsal 

 sepal ovate-oblong rather shorter than the falcate oblong-lanceolate acumi- 

 nate lateral, petals linear-oblong falcate, lip twice as long as the sepals 

 3-cleft to above the middle, side lobes subulate-lanceolate falcately 

 recurved longer than the straight midlobe, spur very large thrice as long 

 as the beaked ovary thickened from below the middle. 



CEYLOX; at Kandy, Walker; at Ramboddi, alt. 3000 ft., Thwaites. 



Stem 6-18 in. Leaves 4-10 in., base contracted. Spike 3-10-fld. ; bracts large, 

 ovate-lanceolate ; ovary narrowly winged, shortly pedicelled ; flowers 1-| 2 in. diain., 

 white ; ovary 1^ in. long ; lateral sepals spreading or deflexed, dorsal rather shorter 

 acute as long as the petals ; spur 3-| in., green, narrowly clavate. mouth with a 

 tooth; midlobe with deflexed sides; anther-cells divaricate; caudicles of pollinia 

 exactly as in H. longicalcarata ; stigmatic processes elongate^ clavate ; rostellum 

 triangular. 



43. XX. rhynchocarpaj Hook. f. ; stem leafy, leaves lanceolate, 

 spike short dense-fld., dorsal sepal cymbiform half as long as the broadly 

 ovate-oblong lateral, petals linear, lip as long as the sepals 3-lobed to the 

 middle, lobes linear-lanceolate acute mid one longest, spur much longer 

 than the long slender beaked ovary. PH. stenopetala, Lindl. Gen. & 

 Sp. Of chid. 324 (not of p. 319). Platanthera rhynchoearpa, Thwaites 

 Enum. 310. 



CEYLON ; above Galagama, alt. 4000 ft., Thwaites. 



Stem 1-2 ft., leafy below the middle. Leaves 2-6 in., sessile. Spike 2-3 in., 

 dense-fld. ; bracts slender, equalling the ovary or longer ; flowers white, -i f in. 

 diam. ; lateral sepals deflexed, subacute; spur 1-li in., cylindric, green, obtuse; 

 anther-cells divaricate, tubes straight ; glands of pollinia minute ; stigmatic pro- 

 cesses elongate, incurved, adnate to the mouth of the lip ; rostellum minute. 

 Lindley's H. stenopetala of p. 324 (not of p. 319) is I think a starved specimen of 

 rhynchocarpa.
