Upper Guinea. Niger Territory, Hansal. 
In the original description of this plant (Oesterr. Bot. Zeitschr. 1858, 82), Schott 
states that the segments of the leaf are “ linear-lanceolate ” and resemble those of 
Corynophallus Afzelii, Schott (A. leonensis, Lem.), whilst in his Prod. Aroid. he 
describes them as “ obverse oblong-lanceolate, cuspidate-acuminate.” The odour is 
said to be fragrant. I have not seen the plant, but it seems to be very similar to 
A. Barteri, N. E. Br., and to differ in being smaller in all parts.

I have not seen this species. The name has been changed because of the pre- 
existing A. sparsiflorus, Hook. f.
