Habenaria.~] CXLVIII. ORCHIDE^J, (J. D. Hooker.) 163 



Stem with spike 20 in. Leaves 3-5 in., membranous, upper smaller. Spike 

 8 in., very slender ; bracts in., ovate-lanceolate; flowers i in. diam. ; sepals and 

 petals membranous, 1-nerved, lateral sepals deflexed ; long segments of lip 1 in. ; 

 spur sub 2-lobed, with a very short contracted neck; ovary small, with a thick 

 dorsal ridge and terminal beak, cells parallel (tubes short upcurved ?) ; pollen grains 

 few, large, glands not seen j stigmatic processes clavate ; rostellum erect between 

 the cells. Closely allied to S. aristata, though with so different a spur. 



ftt Leaves few radical, or solitary and cauline. 



98. K. lacertifera, Bontli. Fl. HongJc. 362 ; stem or scape stout or 

 slender with few or many erect sheaths, leaves usually radical ovate or 

 oblong, spike elongate few- or many-fld., bracts narrow longer than the 

 erect very small flowers, lateral sepals linear-oblong obtuse, lip equalling 

 or longer than the sepals trifid tripartite or obtusely 3-toothed, lobes or 

 segments short subequal or the lateral long, spur minute ovoid or globose.

KHASIA, NAGA and MUNNIPORE HILLS, alt. 2-4500 ft., TENASSEEIM, TAVOY 

 and PENANG, Wallich. DISTEIB. Hong Kong. 



Stem 6-10 in. ; sheaths ^-1 in., lanceolate. Leaves few,- 1-2 in., spreading, 

 acute or obtuse. Spike 3-10 in., slender, lax- or dense-fld. ; lower/bracts often -f in. ; 

 ovary -|-i in., slender, erect, not beaked; sepals | in., 1-nerved, dorsal ovate- 

 oblong, obtuse ; petals variable, rather thick ; lip very variable in length, and in 

 length of lobes or segments, limb with a short spur over the short broad claw ; 

 anther minute, cells nearly parallel, tubes ; pollinia ovoid, grains large, glands 

 obscure ; stigmatic processes small ; rostellum a plicate-membrane stretched across 

 the base of the anther but not ? concealing the glands. Capsule -| in., .sessile, 

 oblong, obtuse. Both this and the following var. are found in Penang. Lindley 

 errs in giving " Nepal, Wallich," as a habitat. I suspect that Lindley's Glossula 

 tentaculata (Bot. Reg. t. 862), of Hong Kong, is only a form of this with elongate 

 filiform side lobes of the lip. 



Var. robusta; very stout, 12-18 in., leaves 3-5 by f-1 in., spike very long 

 many-fld., lateral segments of lip slender exserted much longer than the middle 

 one. Penang, Wallich, Maingay (Kew Distrib. 1662, Spiranthes), Curtis. 



99. IX. g racillima. Hook. f. ; stem long filiform, leaves subradical 

 narrowly linear, spike elongate, flowers few minute distant, bracts shorter 

 than the curved ovaries, lateral sepals linear-oblong, petals broader ovate 

 obtuse fleshy, lip very short fleshy trifid lobes obtuse, spur very short 

 inflated 2-lobed. Coeloglossum Mannii, Reickb. f. in Linncea xli. 54. 



KHASIA HILLS, alt. 4-5000 ft., on grassy hills, common. MTTNNIPOKE, Clarice. 



Stem 6-16 in., with a few subulate sheaths. Leaves 1-3 by | in., alternate, 

 acuminate. Spike 2-6 in. ; flowers -i in. apart ; bracts % in. ; ovary ^ in. ; sepals 

 T T r in., 1-nerved ; lip shorter than the sepals, claw as broad as and hardly shorter 

 than the blade, midlobe rather the longest ; pollinia most minute, broadly pyriform, 

 subsessile on one large flat ovate (2-fid ?) gland, grains large.
