Bomole, 907 m. alt., on tree at edge of rain forest, Dec. 1941, Mo- 
reau [11 (Tyrer). ** Flower white including pedicel, only extreme tip 
of spur flesh pink, anther deep yellow ; diurnal scent resembling Ling’’ 
Amani, 750 m. alt., epiphytic on Parinari sp., Dec. 1941, Moreau 112. 
“Flower white, pedicels and tip of spur yellowish flesh-coloured, 
scented.”” 
A characteristic member of sect. Au-microcoelia only 
to be distinguished from some other species by careful 
examination. The distinguishing features are the heather- 
scent, in allusion to which the specific epithet is given, 
the broad and obtuse constantly 1-nerved tepals which 
are devoid of colored or thickened median band and are 
almost devoid of crystal-containing sacs, and the rather 
slender much branched roots. It is evident that there are 
a number of species closely allied to MW. Guyoniana 
(Reichb.f.) Summerh., differing in combinations of 
rather minute but, I think, quite significant characters. 
Whether these are true species or only local geographical 
races or varieties of one widely distributed species can 
only be decided when much more material is available.
