Under the name of Cameroon cardamoms, the fruits of several closely related species of Aframomum appear to have entered commerce. The statement made by Sadebeck3) (Kultur-gewachse der deutschen Kolonien, Jena 1899, p. 171) that the Cameroon cardamoms are derived from Amomum angustifolium, Sonnerat, is not correct. Neither is the statement correct which was made by D. Hanbury in an article on the cardamoms of tropical Africa (Pharmaceutical Journal III. 2 , 642) according to which Amomum Daniellii, Hook. f. and A. angusti-folium, Sonnerat, are identical.
1) According to K.Schumann's monograph on the Zingiberaceae (in Engler's Pflanzenreich, fascicle 20), the synonyms of this plant are: Amomum angusti-folium, Sonnerat, A. madagascariense, Lam., A. nemorosum, Boj., A. sansi-baricum, Werth. This nomenclature does not agree entirely with that of the Index Kewensis. The latter, however, is no longer authoritative in this case.

According to Y\. Schumann's monograph on the Zingi-beraceae (Engler's Pflanzenreich, fascicle 20) the former species Amomum angustifolium, Bak., has been separated into two species, viz., Aframomum Daniellii, K. Schum. (Amomum Daniellii, Hook, f.), and Aframomum Hanburyi, K. Schum.
The, Cameroon cardamoms distilled by Schimmel & Co. were derived from the first species, whereas the cardamoms distilled by H. Haensel and described by W. Busse (Arbeiten aus dem Kais. Gesundheitsamt 14  139) were probably derived from Aframomum Hanburyi.
