Now that Dracaena marginata has been classified as a synonym of Dracaena reflexa var. angustifolia, how should the cultivars of the former be named? For example, what would be the new name for Dracaena marginata 'Tricolor'? It seems problematic since 'var.' is not to be used to name a cultivated variety. Therefore Dracaena reflexa var. angustifolia 'Tricolor' would be incorrect, wouldn't it?
That would be OK, you can have cultivars of varieties. What you can't do is use the rank of variety to name an individual cultivar (i.e., you can't have "Dracaena reflexaa var. tricolor")
