Mawillaria ringens, which was described from a sin- 
gle inflorescence, is represented in our herbarium by a 
tracing of the sketch of this species from the Reichen- 
bachian herbarium. While the type description cites the 
source as Oaxaca (Karwinski) and Guatemala (Warsce- 
wicz), the sketch is labeled ‘‘Costa Rica, No. 42.’” How- 
ever, the drawing of the scape and floral analysis seem 
to coincide well with the description. The mid-lobe of 
the lip is shown as rhombic-ovate. 
Mawillaria Tiirckheimi trom Guatemala, of which 
we have a drawing of the type made under the super- 
vision of Dr. Schlechter, appears to be identical with JZ. 
ringens. While the only possible comparison is confined 
to the inflorescence, the only discrepancies between these 
species seem to be the very slightly larger flowers of M. 
Tiirckheimii which is credited with an oblong rather than 
rhombic mid-lobe of the lip and an obtuse rather than 
acute callus. Of course, the latter character evidently 
varies with drying etc. M. Tiirckheimi is described as a 
caespitose plant with leaves 30-40 em. long and 3.8—4.5 
em. wide. 
Mawillaria Rousseauae from Panama, represented in 
our herbarium by a floral analysis of Powell 116 (not the 
type) made under the supervision of Dr. Schlechter, 
varies from M. Tiirckheimii only in its somewhat smaller 
vegetative proportions (the leaf being 20-25 em. long and 
2.5-8 cm. wide) and in the mid-lobe of the lip which is
