9. Strophanthus bullenianus, Must. Add: Gilg in Engl. Mon. 
Afr, Pfl. vii. 38, t. 3, fig. C. 
Gilg retains S, Schlechteri as a distinct species (l.c., t. 3, B). The figure given 
by Gilg confirms my opinion that S. Schlechteri is identical with S. bullenianus. It 
represents a branchlet with flower buds ready to open out. At this stage the 
corolla-tails have not yet attained their full length, and, if compared with those of 
flowers of S, bullenianus of the same age, do not show any marked difference. 
It is true S. Schlechteri has more hairy sepals than Soyaux’s plant (No. 55), but this 
Is an exception, the indumentum of the other specimens quoted by me under 
S. bullenianus being of the same character as shown in Gilg’s figure of S. Schlechteri.

The follicles collected by Mann in Fernando Po in 1860 referred to by me in a 
note to S. Preussii do not belong to this species, as Gilg who had an opportunity of 
examining seeds of this species has pointed cut. A description of the follicles aud 
seeds will Le found under S. bracteatus, Franch., which Gilg, after an examination 
of an authentic specimen, declares to be identical with S. Preussit.
