column more than vaguely indicated. The position of the species 

 in the subgenus Platyclinis (which, according to Pfitzer and 

 Kranzlin, is characterized in part by the presence of stelidia on 

 the column and by the comparative size of the middle lobe and 

 of the lateral lobes of the labellum) is therefore significant and 

 indicates either an oversight or an absolute misinterpretation 

 of structural details. If the conspectus of the genus Dendro- 

 chilum in the Ccelogynince is followed, D. cinnaharinum on every 

 count would be placed in the subgenus Aphanostelidion and by 

 no means in the subgenus Platyclinis. Therefore it is supposable 

 that Pfitzer overlooked the characteristic structure of the label- 

 lum and column in the material on which he based his concep- 

 tion of the new species. 



It is much to be regretted that error is so difficult to avoid 

 in the study of minute flowers of complex structure, as the con- 

 sequences of such error are far reaching and likely to lead to 

 duplication of names and, in the absence of types, to constant 

 confusion.
