ville, close to roots of large shady trees, very abundant, December

of 20-100 plants growing at foot of large trees, Dec. 27th 1924, Von

This species is very similar to M. pygmaea Summeth. 
in floral structure and general growth, but is a much 
larger plant with larger leaves and minor differences in 
the flower structure as indicated in the diagnosis. From 
most other species of section Katochilos, it may be dis- 
tinguished by the very short stem, the leaves thus appear- 
ing almost on the ground. It appears to be decidedly 
local in occurrence, though it may be very abundant 
where it does occur.
