In 1895 Engler published Citropsis Schweinfurthii, which was based on 
a single unbranched twig without flowers or fruit collected by Schwein- 
furth (No. 3656) in April, 1870, in the “ Galleriewaldungen ” at Uando 
(altitude 700 to 800 m.; lat. 4 0 18' N., long. 28° 22' E.), about 260 km. 
northeast of Albert Nyanza. The twig was originally some 33 cm. long, 
with 12 intemodes. The basal intemode, with a trifoliate leaf, was sent 
to Kew Herbarium in February, 1878, where it is now preserved. The 
rest of the specimen is in Prof. Schweinfurth’s herbarium in the Dahlem 
Museum and is the type upon which Prof. Engler based the species. 
In the original description of the species the leaves are said to be trifo¬ 
liate, but in this specimen one of them, the fifth from the tip of the twig, 
is pinnately 5-foliate with a well-developed, broadly winged rachis 
between the first and second pair of leaflets. One of the lateral leaflets 
of the terminal pair is missing, but the shape and position of the terminal 
leaflet show clearly that it was present during the life of the plant and 
was probably lost after the specimen was dried, as has happened to seven 
or eight leaflets belonging to other leaves of this same specimen. 
The discovery of this pinnate leaf on the type specimen is of impor¬ 
tance in justifying the reference to this species of a number of pinnate¬ 
leaved specimens from the eastern part of equatorial Africa. 
A fruiting specimen was collected at a ferry of the Ituri River about 
60 km. WNW. of Albert Nyanza in latitude 2 0 55' N. (altitude 900 meters) 
by Dr. F. Stuhlmann (No. 2641) on August 24, 1891, in his journey 
around the great lakes of equatorial Africa. Stuhlmann mistook the
