We propose the adoption of the word cultigen to designate plants whose origin or selection is primarily due to intentional human activity. The word would be useful in general discourse about “wild” and “cultivated” plants and would clarify the respective scope, terminology and concepts of the International Code of Botanical Nomenclature (ICBN) and the International Code of Nomenclature for Cultivated Plants ICNCP. Associated with this proposal is the possibility of making the distinction between these two kinds of plants explicit through their names.
The use of general descriptive names, registered names, trademarks, etc. in this publication does not imply, even in the absence of a specific statement, that such names are exempt from the relevant protective laws and regulations and therefore free for general use.
The name Callistemon rugulosus (D. F. K. Schldl. ex Link) DC. is adopted for the species which has been known incorrectly as Callistemon macropunctatus (Dum.-Cours.) A. B. Court, a name whose basionym Metrosideros macropunctata Dum.-Cours. is of uncertain application. The name Callistemon glaucus (Bonpl.) Sweet is taken up for the species to which the name Callistemon speciosus (Sims) Sweet has been misapplied. Plants previously referred to Callistemon paludosus F. Muell. are now referred to Callistemon sieberi DC. with which Callistemon salignus (Sm.) Sweet var. australis Benth. sensu stricto is synonymous. The name Callistemon pityoides F. Muell. is taken up to replace the previously misapplied name C. sieberi DC..
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
