151. I. (Eriospermum) perringiana, Dammer in Engl. Jahrb. 
xxiv. 460, and in Gard. Chron, 1897, xxii. 410. 
Introduced from the Cameroons by Johannes Braun, and flowered in the Berlin 
Botanic Garden. 
According to Hallier, who has examined a specimen in the Berlin Herbarium,. 
this is a synonym of the widely spread South American species J. bonariensis, Hook. 
(= JZ. Sellowti, Penny), and not a native of West Africa. (See Hallier f. in Engl. 
Jahrb. xxviii. 50.)
