Coloratum, coloured, expresses any colour in a leaf besides green, as in ''Arum bicolor, Curt. Mag. t. 820, Amaranthus tricolor, and others of that genus, Justicia picta, Hedysarum pictum, Jacq. Ic. Rar. t. 567, Tradescantia discolor, Sm. Ic. Pict. t. 10, Pulmonaria officinalis, Engl. Bot. t.'' 118.

Variegatum, variegated, is applied to a sort of variety or disease, by which leaves become irregularly blotched with white or yellow, like those of Striped Grass, Arundo colorata, Fl. Brit.; as also the Elder, the Mentha rotundi folia, ''Engl. Bot. t. 446, and the Aucuba japonica'', which last is not known in our gardens in its natural green state.

Nudum, naked, implies that a leaf is destitute of all kinds of clothing or hairiness, as in the genus Orchis. Nudus applied to a stem means that it bears no leaves, and to a flower that it has no calyx.
