ORCHIDACE^ 



sepal about 7.5 mm. long, oblong, obtuse or subacute, strongly- 

 concave. Petals about 6.5 mm. long, 2.3 mm. broad near the apex, 

 linear-spatulate, falcate, broadly rounded above, obtuse or sub- 

 acute. Lip about 9 mm. long, 5.5 mm. broad above, spatulate in 

 outline, deeply three-lobed; claw long, in natural position sac- 

 cate at the base then abruptly channeled-conduplicate, when ex- 

 panded broad and gradually dilated into the reflexed lamina; 

 limb suborbicular, provided near the base witli a pair of bilobed, 

 oblong, papillose calli and furnished near the apex with a central, 

 similar, more or less distinct papillose callus ; lateral lobes small, 

 auriform, obtuse or acute, separated from the mid-lobe by a nar- 

 row sinus ; middle lobe reniform, retuse or shallowly bilobed and 

 apiculate, margins undulate. Column about 3 mm. long, clavate, 

 densely hairy, narrowed into a foot which is about 6.5 mm. long 

 and dilated and thickened at the extremity. 



Considerable vegetative variability is shown by the collections 

 of this species ; in Cleme7is 303, a very advanced form, the ra- 

 cemes markedly surpass the leaves, and in material gathered 

 by Haslam there are short ovate- lanceolate, very fleshy leaves 

 ±14 cm. long, 3 cm. wide. 



There appear to be no authentic species that are very near 



allies of this plant, but Eria rubiginosa BL, registered sub Tri- 



chotosia rubiginosa Bl. by Kranzlin in his monograph (Engl. Das 



Pflanzenreich IV, 50. II. B. 21 (1911) 155) as a doubtful species, 



seems very close. The vegetative characters, which alone are 



given in the original description of this species, are identical 



with the material from Mount Kinabalu.
