Vol. I, No. 5 
collected by J. Milbraed in 1908, which seem to be referable to Ciiropsis 
Schweinfurihii. One specimen (No. 2394) is from Fort Beni, in extreme 
western Uganda, on the Semliki River, about half way between Albert 
Nyanza and Albert Edward Nyanza. This specimen consists of a single 
twig with 5-foliate leaves, single spines, and two young fruits. The other 
(No. 2280) is from Kikufu, near Irumu, in the Ituri River valley, only a few 
kilometers south of the ferry where Stuhlmann crossed the Ituri and 
collected his No. 2641. This second specimen of Milbraed consists of 
two twigs with mostly 5-foliate leaves, but one of them has a trifoliate 
leaf almost exactly like those of Schweinfurth’s original specimen from 
Uando. 
Limonia Poggei Engler, which the writers have referred doubtfully to 
Ciiropsis Schweinfurihii , was based on a single specimen collected by Pogge 
(No. 668) June 1, 1882, at Lulua, latitude 6° S., on the Lulua River, an 
affluent of the Kasai River. The type specimen preserved in the Dahlem 
Herbarium shows a single twig with 11 or 12 intemodes, but with only 
one 5-foliate leaf remaining attached. There is also one loose leaf and 
a single fruit. Pogge's original label notes that the fruit is yellow. An 
examination of the fruit preserved with the type specimen at Dahlem 
shows it to possess distinct pulp vesicles. There is nothing in the 
specimen or in the description to distinguish it from Ciiropsis Schwein¬ 
furihii , and as it occurs at a considerable altitude, 660 meters, and only 
500 km. west from the nearest of the great African lakes, while Uando, 
the type locality, was some 250 km. west, its geographic range is not 
such as to render its inclusion in the species improbable. 
It is interesting to note that all the reported localities of Ciiropsis 
Schweinfurihii are above 660 meters altitude, the highest reported being 
1,550 meters at Toro, Mpanga Forest, Uganda. 
There is, however, a specimen in the herbarium of the Museum 
d’Histoire Naturelle at Paris, collected by Thollon (No. 1049) in June, 
1888, in French Congo on the Niari River between Bounanza and 
Komba, that can scarcely be distinguished by its leaf characters from 
Ciiropsis Schweinfurihii. Bounanza is only 250 km. from the Atlantic 
Ocean and at an altitude of only 130 meters. Thollon states on his 
original label that this plant occurs in all the woods from Komba to 
Bounanza. If this material proves to be Ciiropsis Schweinfurihii , it will 
give this species the greatest range both in distance and in altitude of 
any yet known in the genus Citropsis. 
There is a specimen 1 in the herbarium of the botanic garden at 
Brussels, collected by Messrs. Em. and M. Laurent below Ibaka, on the 
Sankuru River, Congo, on November 24, 1903, and also a specimen in 
the National Herbarium at Washington, D. C., collected by Messrs. 
Laurent below Bolombo, on the Sankuru River, on January 2, 1904. 
1 This specimen seems to have been referred to Limonia Demeusei by M. ftmile de Wildeman. See his 
Mission £mil Laurent (1903-4). v. 1, p. 238. Brussels, 1905-1907.
