ORCHIDACEiE 



Plant slender for the genus, about 28 cm. tall. Rhizome creep- 

 ing, woody, composed of a moniliform series of approximate corms 

 or pseudobulbous thickenings, closely invested by the long fibres 

 of sheaths. Roots rather few, stout, rigid, fibrous, flexuous, un- 

 branched, densely lanuginose, longitudinally sulcate, about 2 mm. 

 thick. Leaves about 17 cm. long, 6.5 cm. wide, broadly elliptic, 

 acuminate, gradually narrowed to the petiole, erect, membra- 

 naceous in the dried specimen, many-nerved with seven nerves 

 prominent beneath. Petiole ±4 cm. long, surrounded and sur- 

 passed by the long fibres of sheaths. Scape much exceeding the 

 leaf, about 33 cm. high, sub-erect from a decumbent base, pro- 

 vided with several tubular scarious sheaths which are short loose 

 and imbricating below, longer closer and very remote above, 

 striate in the dried plant, upper portion provided with about two 

 linear scarious bracts. Raceme about 5.8 cm. long, slender, arcu- 

 ate or nodding, rather compact. Lower bracts of the inflorescence 

 about 1.75 cm. long, 2.2 mm. wide, linear-attenuate, scarious, 

 ascending, much exceeding the flowers. Flowers very small for 

 the genus, perianth tubular, pellucid in the dried specimen. Sepals 

 and petals similar, the paired members somewhat varying. Lat- 

 eral sepals about 7 mm. long, 1.4 mm. wide at the base, some- 

 times broader across the middle, linear-falcate and decurved,long 

 acuminate, with one nerve prominent. Dorsal sepal about 7 mm. 

 long, 1.5 mm. wide across the middle, linear, more or less gently 

 falcate, acute, one-nerved. Petals about 7 mm. long, 1.75 mm. 

 broad in the middle, narrowly falcate-lanceolate, acuminate, one- 

 or indistinctly three-nerved. Lip forming with the lateral sepals 

 a sac or short spur, lamina in natural position tubular-involute, 

 when expanded three-lobed, ovate in outline, about 5.5 mm. long, 

 4.5 mm. broad across the lateral lobes ; lateral lobes spreading, 

 small, oblong-ovate, acute, oblique, at the base of each a membra-
