Cultivated plants Available to Purchase

Article 28.1 of the current (1978) edition of the International Code of Botanical Nomenclature states: ‘Plants brought from the wild into cultivation retain the names that are applied to the same taxa growing in nature’. At first sight the provision seems worse than unnecessary, in that we know for a fact that many wild plants acquire new and very different names when they are cultivated. But, as is often the case, a little reflection and we can see what the Code intends to say—namely, that there is only one system of scientific, botanical nomenclature, and that the same scientific name applies to a taxon whether it is growing in the wild, or stored in a herbarium, or cultivated in a garden.
