TANGANYIKA Trrrirory: Luengera Valley, north of Korogwe, near 
Magoma, 450 m. alt., epiphytic on small tree in grassland, Dec. 1942, 
Native collector; comm. W. M. & R. FE. Moreau 445A. ** Flowers 
glistening white, column and tip of spur orange; no scent.”’ 
This interesting species agrees completely with section 
Eu-microcoelia in the column structure and relatively 
short spur but possesses an exceptionally large lip, thus 
making the flowers much larger than in the other species 
of the section. The roots are very stout and densely cov- 
ered with erect hyaline papillae which give the surface 
a curious matt appearance. M. Guyoniana (Reichb. f.) 
Summerh. is probably the nearest relative but that spe- 
cies has more slender and smooth roots, and flowers 
about half the size. 
Among a collection of spirit specimens of leafless An- 
graecoids received recently from Mr. W. J. Eggeling of 
the Uganda Forestry Service, are several new records 
for that country.
