CocHLOsPERMUM NILoTICcUM, Oliver. 
It is only with some hesitation that I have identified this plant 
with those at the Kew Herbarium ‘collected by Petherick on the 
Upper Nile and by Schweinfurth. It may very well be a new 
species, and is almost certainly a new variety. 
Near Moria, on Upper Scarcies River, Feb. 13, no. 4793. 
POLYGALACER. 
SECURIDACA LONGEPEDUNCULATA, Fres., var. Parxtt, S. Elliot ; 
foliis oblongis ellipticis obtusis ovatisve basi angustatis, subtus 
glaucis ; pedicellis 15~27 mm. ; petalis lateralibus obovatis cu- 
neatis 3-6 mm. 
Gambia River, Mungo Park! A shrub with red flowers some 
4 feet high, on bare rather dry ground near Falaba, March 12, 
nos. 5140 & 5149. 
I should have described this as a new species were it not for 
the very wide distribution according to Professor Oliver, who 
includes under this name two Abyssinian forms described as 
different species by Hochstetter, a Zambesi form specifically 
described by Klotzsch, as well as a Niger plant, Barter, no. 1198.
