UrrER GursEA. Niger Expedition, at Abok, Barter, 324. 
This shrub was first collected by Barter on the Niger Expedi- 
tion in 1858, and subsequently by Speke and Grant in the Madi 
Country in 1863; in 1904 and again in 1905 by myself, but 
without flowers. The description of the flower is taken from 
Dr. Bagshawe’s plant in the British Museum, collected in Unyoro 
in November 1905. Barter’s Niger plant has a more strongly 
toothed calyx than the Nileland specimens.
