acute, gradually attenuated above the middle. Petals 4.5 mm. 

 long, about .75 mm. wide, one-nerved, falcate, linear-oblong, 

 acute. Labellum 3 mm. long, three-lobed ; lateral lobes triangular, 

 irregularly dentate, antrorse, arising near the middle of the label- 

 lum; middle lobe triangular-ovate, acute, entire, about 2 mm. 

 long, 1.5 mm. wide. Disc bicarinate, the median nerve promi- 

 nent. Gynostemium slender. Lateral stelidia oblong, subobtuse, 

 equaling the terminal wing, arising from the middle of the col- 

 umn just below the stigmatic orifice. Terminal wing rounded,

3. Dendrochilum conopseum Ridl. in Stapf in Trans. Linn. 

 Soc. ser. 2,4 (1894)236. 



This species was originally discovered by Haviland in 1892. 

 Aside from the type material, no other specimens have been 

 secured. I have seen a photograph of the type which shows an 

 elongated rhizome with the fusiform pseudobulbs far apart, and 

 the slender scape basal. The general aspect of the plant recalls 

 D. simplex J. J. Sm. as represented by a specimen in my herba- 

 rium collected on Marei Parei Spur by Clemens, but the leaves 

 of D. simplex are oblong-lanceolate rather than oblong-elliptical 

 and the inflorescence is terminal. This is the only representative 

 of § Eudendrochilum among the species now known to be natives 

 of Mount Kinabalu.
