ad extremam laminam + 7 mm. loiigo, calcari conico in 

 mediano bifido inter sepalos laterales exserto, in inferior- 

 ibus duo-trientibus ventricoso et erecto ad columnam 

 deinde abrupt© contracto lamina terminali ovali vel 

 obovata integra et recurva, laciniis lateralibus parvis et 

 erectis; columna (rostello excepto) + 2'5 mm. longa; 

 rostello profund© bipartite, erecto, circa (cum glandula) 

 2 mm. longo, membranaceo; stigmate prope a basi 

 columnae, cavo, erecto, cum alis subgrandibus lunatis. 

 Habitat— Bevdi Deva (C. T. White, No. 605). 



Root a creeping rhizome. Leaves near the base, 3 or 4, 

 elliptical or oblong-elliptical, acuminate, entire, glabrous, 3-4 

 main parallel nerves with many subsidiary ones and trans- 

 verse reticulations; lamina 3 to 9"5 cm. long and 1'5 to 3*3 

 cm., wide; petioles 2*3 to 3 cm. long with diiL.ted scarious 

 sheathing bases. Stem almost glabrous, slightly pubescent, 

 with 2 acute hairy bracts. Total height of plant about 34 cm. 

 Spike + 14 cm. of about a dozen sessile distant flowers, each 

 subtended by an acuminate ovate-lanceolate bract which is 

 usually shorter than the ovary. Rhachis, bracts, and outside 

 of the flowers beset by minute glandular hairs. 



Ovay sessile, rather slender, hairy, much twisted, + 11 

 mm. long. Dorsal sepal narrow-cucuUate, erect, 3-nerved, 

 + 7 mm. long, tip rather obtuse. Lateral sepals free, inserted 

 obliquely below the labellum, falco-lanceolate, 3-nerved, total 

 length (from lowest point of insertion) about 8 mm. Lateral 

 petals same length as dorsal sepal and connivent with it to 

 form a hood, membranous, 1 nerved, connate at the extreme 

 tips, narrower in the lower than upper half, linear-falcate, 

 much narrower than the sepals. Labellum inferior, shortly 

 adnate to the base of the column, sessile, + 7 mm. (including 

 the spur) when fully extended; spur conical, short, bifid 

 antero-posteriorly, exserted between the lateral sepals; lower 

 two-thirds ventricose, erect against column, suddenly con- 

 tracted into a short neck then dilated into an entire oval or 

 obovate membranous recurved terminal lobe; lateral lobes 

 small erect; lamina glabrous throughout, traversed by several 

 prominent longitudinal nerves. 



Column proper short + 2"5 mm. long, or including ros- 

 tellum and gland + 4'5 mm.; anther posterior ereet; 

 rostellum erect, membranous, deeply bipartite, gland oval or 

 elliptical (the division of the rostellum is only evident after 

 removal of the gland) ; stigma situated on lower face of 

 column near the base, erect with rather large crescentic wings. 



A species, P. chinenais, Rolfe, has been recorded (under 

 the name of P. Henryi) from New Guinea by Schlechter, and
