ORCHIDACE^ 



or obtuse, one-nerved, minutely ciliolate and papillose above. 

 Lip minutely clawed, rather fleshy in texture, in natural position 

 gently decurved below the middle with the lower sides erect 

 and subconduplicate, the anterior portion elliptic-ovate, acute 

 or obtuse with lateral margins somewhat decurved ; limb when 

 expanded ovate-oblong, appearing subtrilobed, about 4.5 mm. 

 long (rarely 5.2 mm. long), 2.4 mm. wide below, a pair of small 

 approximate fleshy calli at the base extending longitudinally 

 down the lip as fleshy indistinct ridges, three-nerved. Column 

 minute, provided with a pair of short triangular acuminate arms. 

 Foot stout, arcuate, with a prominent porrect tubercle that ter- 

 minates a fleshy ridge extending from the base. 



This species is very near to Bulbophylluvi coriaceum Ridl., but 

 it diiFers in its remote pseudobulbs, markedly longer and some- 

 what wider leaves, much taller scapes bearing more flowers and 

 unthickened margins of the lip. From B. k'mabaluense Rolfe it 

 is distinct in the much larger leaves and flowers.
