Help wanted to an English translation, write to me, if you know where this can be found.
Habitat:
Forest
Note:
Flowers pale greenish yellow. Lip dark purple at insertion and becoming creamish at length.
This rather small and not very striking species is allied to M. Weberbaueriana (Kraenzl.) Summerh., from which it differs in the characters given in the diagnosis. Both species possess two broad lines of short hairs, one on each side of the median vein, in the lower part of the lip. The name is given in allusion to the dark coloured auricles (ears) at the base of the tip.
Distribution:
Liberia
