includes the concept M. brevipedunculata.

The recently acquired drawings showing the habit 
and floral analyses of Mawillaria Reichenheimiana trom 
the Reichenbachian herbarium demonstrate clearly that 
this species includes the concept Maaillaria pachyacron, 
as represented by similar habit and floral drawings made 
under the supervision of Dr. Schlechter. 
The only discrepancy in these concepts that we can 
discover is that the lip of MM. Reichenheimiana bears some 
short filiform papillae surrounding the median callus. 
These papillae appear to be absent in M. pachyacron as 
well as in most of the numerous Costa Rican specimens 
which are referable to this species. 
The size and proportions of the leaf seem to consti- 
tute a variable character. The extreme length of the 
leaf-blade in the many Costa Rican specimens examined 
appears to be about 13.6 em., while the width of some of 
the elliptic-ligulate leaves is about 1.2 cm. Some blades 
are almost subsessile, while others have a petiole up to 
3cm. long. Furthermore, the mottling of the leaf, which 
is a characteristic of M. Reichenheimiana, appears to be 
absent from many dried specimens from Costa Rica which 
are undoubtedly referable to this species. Doubtless this 
maculate character is observable chiefly in living speci- 
mens, as the type of M. Reichenheimiana consisted of 
garden material and as this character has been noted by 
the collectors in some instances.
