Spike with rather distant flower, 12-21 cm. long. Flower- 

 bracts ovate or ovate-lanceolate, exceeding ovaries in length. 

 Ovaries rather short and slender. 



Flowers dark reddish-brown. Segments of perianth 

 narrow-lanceolate. Lateral sepals connate except at extreme 

 base and extreme tips, about 85 mm. long, conjoined breadth 

 about 3 mm.; dorsal sepal slightly incurved, about 10 mm. 

 long by 2 mm. broad, 5-nerved, \erj acuminate. Lateral 

 petals narrow falco-lanceolate, 5-nerved, 7 mm. long by 

 1'25 mm. broad. Labellum on a very short claw, slightly 

 arched about the middle, about 6'5 mm. long by about 3 mm. 

 broad, lanceolate, membranous border narrow not crisped, 

 margin entire almost plain ; inner plate relatively large, 

 lanceolate, about 5 mm. long by about 2 mm. in its greatest 

 width, extending to Vvdthin a, short distance of the apex, 

 traversed by three main and many subsidiary nerves, not 

 thick or prominently raised, with narrow free margin in 

 posterior two-thirds. Column about 2 mm. high; anther, 

 rostellum, and lateral appendages about same height. Lateral 

 appendages of column blunt linear-falcate, membranous; 

 posterior border notched about half-way down, thereafter 

 forming a receding sinuous line. Pollinia attached by a 

 rather short caudicie to a relatively large ovate-lanceolate disc. 

 Stigma at base of column, apparently ovate (in the dried 

 specimens). Lateral Index 82.

The name has reference to the lanceolate shape of the 

 segments of the perianth and labellum. These impart to the 

 flower a slender and characteristic appearance which at once 

 distinguishes it from F. elafum. It further differs from that 

 species in the fact that the dorsal sepal exceeds in length the 

 lateral sepals, in the presence of a claw to the labellum, and 

 in the very much shorter lateral appendages to the column. 

 In elatum these lateral appendages considerably exceed the 

 rostellum in height. 



In P. hrevilahre, Hook, f., the dorsal sepal is shorter and 

 narrower than the lateral ones; the labellum is sessile and 

 abruptly reflexed and reeurved in the middle. 



In the new species the inner plate is not fringed, nor is 

 there any evidence of a second inner plate as in the case of 

 P. Fimbria, Reich, f. 



It is differentiated from P. regium, Rogers, by the 

 lateral appendages of the column which in that species (as in 

 elatum) greatly exceed the rostellum in height; also by the 

 labellum which in P. regium is recurved at right angles, with
