Evidently allied to M. Guyoniana (Reichb. t.) Sum- 
merh. of which it may prove to be a local race or variety. 
It may be distinguished by its smaller size, more slender 
inflorescences, smaller flowers and narrow perianth mem- 
bers including the lip. In general floral structure there 
is close agreement between the two species.

This, like WZ. Sith (Rolfe) Summerh., is a close ally 
of M. Guyoniana (Reichb.f.) Summerh., which they ap- 
pear to replace in Tanganyika Territory. JZ. Stolzi is 
characterised by the spur which is only about half the 
length of the narrow acute lip and is markedly incurved. 
There are, however, specimens in the Kew Herbarium 
from Kenya Colony in which a relatively short incurved 
spur is associated with the broader lip and perianth seg- 
ments of typical JZ.Guyoniana. There is some evidence 
that these three species should more correctly be treated 
as variants of one species with which, perhaps, M.conica 
(Schlitr.) Summerh. should also be associated.
