In describing the peloric form of Thelasis carinata Bl. in Nova 

 Guinea 14:492, 1929, J. J. Smith stated that Oxyanthera papuana 

 should be regarded as a synonym of T. carinata. An examination 

 of Schlechter's collections reveals two prominent differences 

 between these species which merit their separation. The first, 

 mentioned by Schlechter, is that the flowers of T. papuana are 

 nearly twice as large as those of T. carinata. The second is that T. 

 papuana has a pair of stelidia at the apex of the column which are 

 absent in T. carinata.
