ORCHIDACE^ 



of the lip to a point near the apex of the middle lobe, on each 

 side a shorter supplementary keel running from the middle of 

 the lateral lobes to the middle of the median lobe. Column foot- 

 less, about 1.4 cm. long, slender, arcuate, flattened on the ante- 

 rior surface, winged above, the wing shortly dentate at the apex. 



Great variability is indicated by several contemporary col- 

 lections. Clemens 266 shows one inflorescence indicating five 

 flowers. Another collection, Clemens 2Jt.A'> shows stems exceed- 

 ing bb cm. in height, smaller cream-colored flowers, and a two- 

 celled anther with eight complanate, ovoid, waxy poUinia. A frag- 

 mentary specimen collected by Haslam shows shorter leaves and 

 ovate middle lobe of lip. 



This plant is quite characteristic, but in flower structure it is 



similar to Arundina Cantleyi Hook. f.

23. DENDROBIUM Sw. 



One hundred and nineteen members of this large genus have 

 been recorded from Borneo, of which only three were previously 

 known from Mount Kinabalu. In the present work Sarcopodium 

 is regarded merely as a subgenus of Dendrohium.
