ORCHIDACEiE 



Petala oblanceolato-linearia, apice plus minusve obliqua et trun- 

 cata. Labellum gynostemio adnatum, profunde trilobatum ; lobi 

 laterales late patentes, obovati vel obovato-oblongi ; lobus me- 

 dius obcordatus, circa ad medium in lobulos binos suborbiculares 

 divisus, erosus ; calcar breve, rectum, extus pilis sparsim praedi- 

 tum. Gynostemium breve, crassum, clavatum, villosum. 



Plant erect, slender above. Leaves probably several, about 

 25.5 cm. long, 8.5 cm. wide, elliptic, acuminate, narrowed to a 

 long sulcate sheathing petiole, membranaceous in the dried spe- 

 cimen, with three to seven nerves prominent beneath. Pedun- 

 cle including the raceme up to 83.6 cm. long, much surpassing 

 the leaves, very stout below, tapering to a very slender upper 

 portion, puberulent below, densely pubescent above, provided 

 with lanceolate tubular appressed sheaths which are remote. 

 Raceme about 6 cm. long, dense with about two very remote 

 flowers below. Rachis densely pubescent. Bracts of the inflores- 

 cence up to 1.5 cm. long, lanceolate, acuminate, reflexed-spread- 

 ing. Pedicellate ovaries in development long, finely pubescent. 

 Flowers small for the genus. Sepals pubescent without, upper 

 margins involute. Lateral sepals about 7 mm. long, 3.5-4.8 mm. 

 wdde, obovate to oblanceolate-oblong, somewhat oblique, obtuse 

 or subacute, dorsally carinate at the apex, three- to five-nerved. 

 Dorsal sepal about 7 mm. long, 3.3 mm. wide, oblong, obtuse 

 or subacute, dorsally carinate at the apex, three-nerved. Petals 

 about 7 mm. long, 2.2 mm. wide above, oblanceolate-linear, 

 more or less oblique and truncate at the apex, one- or indistinctly 

 three-nerved. Lip adnate to the column at the apex, suborbic- 

 ular in outline, deeply three-lobed, about 6 mm. long, 8 mm. 

 broad across the lateral lobes, pluri-tuberculate at the base ; lat- 

 eral lobes about 3.8 mm. long, 2.5 mm. broad, widely spreading,
