The genus was confounded with Asmorphophallus, not only by Rumphius, but also by Solander and 
Forster.

Viti (Seemann! n. 633, 908; Barclay!). Also collected in the Society (Banks and Solander! 
Forster! Barclay!), Tongan (Herb, Hook.), and Samoan Islands (Sir E. Home!), and Straits of 
Sunda (Staunton !). 
G, Forster quotes Rumphius’s Zacea sativa (which is identical with Amorphophallus campanulatus, 
Blume) and 7. sylvatica (which has not yet been identified) as synonyms of his 7. pinnatifida ; and Solander 
also refers erroneously Rheede’s and Rumphius’s plates to this species. It may be useful to add here 
Solander’s description of this species :—
