 xxiv. 460, and in Garcl. 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 I. honariensis, Hook. 

 (= I. Sellowii, Penny), and not a native of West Africa. (See Hallier f . in Engl.. 

 Jahrb. xxviii. 50.)
