DAWEANJE IN UGANDA LECT. 497 
the African Continent has already been pointed out twelve years 
ago by Dr. Stuhlmann in his suggestive summary in the conclud- 
ing chapter of his work ‘ With Emin Pasha in the Heart of 
Africa. Thus far Mr. Dawe's account also supplements the 
survey work of the botanist of the Anglo-German Boundary 
Commission, the results of which were issued in no. 259 of 
the Journal of this Society last year. It was indeed very tempt- 
ing to folow up by means of Mr. Dawe's collections the 
question of the extent and character of the West African Hylea 
element in the heart of Atrica, or that of the remarkably 
mixed highland flora of Mt. Ruwenzori; but this would have 
required an extensive revision of all the material available from 
that region, and thus widened the scope of this paper far beyond 
reasonable limits. 
My own and my collaborators’ shares in the descriptive part of 
the paper are evident from the authors’ names after those of the 
species ; but I ought to mention that a not inconsiderable part 
of the preliminary work of comparing Mr. Dawe's collection 
was done by Mr. J. Hutchinson, temporary Assistant at Kew.
