 Spike 2 in. ; bracts broadly ovate, obtuse ; flowers | in. long ; sepals broad, obtuse ; 

 petals obovate-oblong, 1-nervedj lip obscurely 5-nerved, broadest in tiie middle; 

 rostellum very long, acuminate, entire. 



5. T. khasiana, Sook.f. le. Plant, ined.; scape witli spike 3-5 in. 

 about equalling the solitary petioled linear leaf, spike elongate lax-fld., lip 

 elliptic- ovate subacute. T. pygmEea, lAndl. m Jowrn. Lmn. Soc. iii. 62 (in 

 part). 



Khasia Mts., alt. 3-4000 ft., Lobb, J. D. B. ^ T. T. 



Fseudoiulhs |-in., depressed-globose. Leaves 2-4 by ^-^ in. Scape and spike 

 rather stout j bracts ovate-lanceolate ; sepals ovate-lanceolate, obtuse ; petals lanceolate, 

 obtQse ; lip 3-nerved, broadest rather nearer the base than tip ; rostellum large, acute. 

 — Very like T. pygmeea, but a much larger plant, without keel or wing on the 



6. T. longrifolla; Hooh. f. le. Plant, ined. ; scape stout with the 

 spike 6-9 in. about equalling the solitary leaf, spike elongate lax-fld., lip 

 elliptic-ovate acute. 



Khasia Mts. .T. D. S. Sr T. T. 



Differs from T. Tchasiana in being very much larger, and in the acute lip. 

 PsB'udob'ulb |-1A in. diam., depressed-globose. Leaf sometimes falcate, |-4 in. 

 broad ; flowers -J in. long. 



Sect. II. OxTAKTHBEA, Bronffn. (G-en.). Pseudobulb 0; stem short, 

 clothed vri.th the equitant sheaths of the linear leaves which are jointed 

 at the sheath. (Oxyanthera is a very natural group). 



7. T. elata, Hook. f. Ic. Plant, ined. ; leaves 10-14 by \-\\ in. tip 

 rounded, scape equalling or exceeding the leaves, raceme long slender 

 lax-fld. 



Peeak, on decayed wood. King's Collector. 



Rootstock as thick as the little finger. Lewves few, sheaths 2-2J by J in., cotn- 

 plicate, coriaceous. Scape very slender, flexuous ; sheaths 3-4, J in. long, 

 membranous, lanceolate ; bracts ovate, acuminate, spreading and reflexed ; flowers 

 i in., narrow, shortly pedicelled ; sepals linear-oblong, acute, 1 -nerved, venation dis- 

 tinct ; petals lanceolate, acute ; lip erect, claw short broad, limb linear subacute, 

 margins waved, base broadly 2-auricled, auricles revolute j rostellum 2-partite, seg- 

 ments obtuse ; poUinia 8, shortly obovoid. — Near T. carinata, Bl. (of which I have 

 seen no flowers), but the leaves are very much longer, the scape very slender, raceme 

 longer, and bracts acuminate. 



8. T. decurva, Hook. f. Ic. Plant, ined. ; leaves 4-6 in., tip narrow 

 or rounded and obtusely notched or subacute, scape very slender, raceme 

 very short decurved, bracts reflexed, lip dagger-shaped from a concave 

 cuneate base terete and fleshy beyond the middle with the crisped margins 

 inflexed and close to the mesial line. 



SlNflAPOBE ; at Krangi, Ridley. Penans, or Government Hill, Maingay. 



Leaves j-f in. broad. Scape shorter than the leaves, filiform, flexuous, sheaths 

 1-2 lanceolate ; raceme i in. ; pedicels ^ in., longer than the oblong bracts ; flowers 

 i in. long, pale fawn colour; sepals ovate-lanceolate acute and narrowly oblong 

 obtuse petals 1-nerved. — This much resembles the figure of 0. micrantha Brong., 

 which is figured as having a stout broadly ovate obtuse lip narrowed into a broad 

 short claw, base concave. The leaves of some specimens are narrow at the tip, 

 others have 2 rounded lobes.
