Comoro Istanps: Grande Comore, Humblot 450 (Tyre in Herb. 
Vienna); Grande Comore, June 1899, Pobéguin. 
Comparison of the type of Aéranthus trifurcus Rehb. f. 
in the Vienna Herbarium (Humblot 450) with the ma- 
terial collected by Pobéguin and described by Perrier 
de la Bathie as Angraecopsis Thouarsii shows that they 
are conspecific. The petals in the Reichenbach type are 
trinerved, while the side lobes of the lip are nearly as 
broad and not quite so long as the middle lobe, just as 
in the Pobéguin specimens. 
I am rather puzzled as to the true nature of the ma- 
terial in the Paris Herbarium under the same number as 
the type, Humblot 450, which was figured and described 
by both Finet and Perrier. These drawings and descrip- 
tions clearly do not agree with the type specimen at 
Vienna, and it is therefore possible that Humblot col- 
lected a mixture of species under his number 450. An 
alternative explanation is that both French authors have 
placed too much dependence on the drawings of the artist 
C. Kastner which appear in both Finet’s plates and as 
parts of Perrier de la Bathie’s illustrations. Examination 
of drawings by this artist on sheets of other species in 
the Paris Herbarium shows that they are sometimes 
highly imaginative and do not agree with my dissections 
of flowers from the same plants. It seems therefore pos- 
sible that the drawings on the sheet of Humblot 450 are 
also inaccurate and have led to a misinterpretation of the 
material; clearly a re-examination of this specimen is 
desirable.
