nodes furnished with splitting leaf-fibres. Leaves elongate, erect and recurved 

 above, fasciculate with about 3-9, linear, gradually attenuated towards both 

 ends, shortly acuminate, serrulato-scabrous on margin, rigidly coriaceo-charta- 

 ceous, coriaceous and canaliculate internally and subcarinate dorsally below, tubu- 

 lar and membranaceoiis-margined at the base, nervate, with a furrow in centre 

 on the upper surface, green, concolorous, slightly shining, glabrous, 28-80 cm. 

 long, 7-13 mm. broad ; midrib slender, prominent beneath as are the lateral 

 main veins which are one on each side ; veinlets 6-17 in whole number. Scape 

 shorter than the leaves including the raceme, lateral, erect, terete, glabrous, 

 with membranaceous acuminate many-nerved sheaths ; the upper sheaths 

 usually apart, usually tubular below, but the uppermost one often without the 

 tube, the longest one attaining nearly 5 cm., the basal ones gradually shorter 

 and imbricated. Kaceme erect, shorter than the scape, more or less secund- 

 ly and laxly 5-10-flowered ; rachis straight or subflexuous, glabrous, subterete, 

 often somewhat obtusely angulate, viridescent or often more or less purplish as 

 is the scape, 10-15 cm. long; bracts slightly shorter than the ovary, 

 narrowly lanceolate, acuminate, membranaceous, with 3 main nerves 

 7-21 mm. long. Flowers about 3|-5 cm. across, slightly odoriferous. 

 Perianth yellowish-viridescent, often shaded with light purple externally, 

 thickish, entire ; outer perianth patent and at length more or less de- 

 flexed backwards, equal in size, linear-lanceolate, sharply acute, .5-nerved, 

 2^-3|cm. long, 4i-6 mm. wide, the lateral ones scarcely oblique in form; 

 inner perianth directed forwards, shorter than the outer ones, narrowly 

 lanceolate, acute or acutish, entire, scarcely oblique in form, 5 or 7-nerved, 

 2-2§ cm. long, 5^- nearly 7 mm. wide, longitudinally purple in centre 

 below. Labellum sessile with the rounded-obtuse and yellow base, 2J- 

 2| cm. long, obscurely 3-lobed ; lateral lobes erect, rounded and entire- 

 edged, white as is the disk, purple-margined and purple barred in the 

 intramarginal portion, the disk thick, with many and minute purple spots 

 within the central canal, the ridges closely approximate, rised in the front 

 portion and rounded-obtuse at its end ; the midlobe much reflexed, ovato- 

 lanceolate, longer than the disk, acutish or subobtuse, crisped-margined, 

 thickish, viridescent, papillose-pubescent and irregularly blotched with 

 purple, 15-17 mm. long, 7-8 mm. broad. Gynosteraiurn erect, arcuate 

 forwards, compressed, 12-14 mm. long, 4-5 mm. wide, glabrous, yellow 

 above and whitish below, purple-spotted on the front surface ; clinandrium 

 obliquely truncate, subdeltoid, with the obtuse or shortly produced dorsal edge ; 

 anther depressed-semiorbicular, truncate on the front margin ; pollinia 4, 

 deltoid-orbicular, compressed, yellow, waxy, the inner ones smaller, the gland
