according to Cordemoy). 
Careful examination and comparison of all these speci- 
mens indicate that they are referable to the same species. 
The specimens from the African mainland are on the 
whole larger than those from Mauritius and Réunion, 
but there is practically no difference between the smallest 
mainland plants and the largest island specimens. In 
floral structure there is very close agreement, at any rate 
as regards the two Southern Rhodesian gatherings of 
which I have seen well preserved flowers. 
Finet’ provides a description and figures of two gath- 
erings (Sacleuw 764 and 765) from Portuguese East 
Africa which he identifies with Rolfe’s Mystacidium pe- 
dunculatum. Although there are no properly preserved 
flowers on Rolfe’s material, in several cases the spur still 
remains. This, even allowing for shrinkage, could not 
possibly have exceeded 1 em. in length and was probably 
nearer 7 mm., which is about the length of the spur in 
Angraecopsis parviflora. On the other hand the flowers 
figured by Finet have a spur which appears, from the 
magnifications given, to be about 2 em. long with quite 
a wide mouth. This certainly does not agree with the 
shrivelled-up spurs on the capsules of MM. pedunculatum. 
It therefore seems almost certain that Sacleux’s plants 
are referable to a different species, which is correctly 
placed in Mystacidium, with which they agree in floral 
structure, especially the lip and rostellum-lobes. 
It should be further pointed out that in no true species 
of Mystacidium are the flowers bunched at the end of 
the inflorescence with a long peduncle below, but are 
spaced out evenly along the greater part of the inflores- 
cence so that the peduncle is comparatively short. In
