Morphology

Tephrosia + virginiana

This is a standard Linnaean binomial made of the genus name 'Tephrosia' and the Latin epithet 'virginiana' (meaning 'from Virginia'), so the combined form straightforwardly denotes a species of Tephrosia originating in Virginia. Although specific botanical details (habit, flower colour, chemical uses) are not implied by the name, an average B1 learner who knows the two constituents would understand it refers to a plant species and its geographic origin.

Etymology

Tephrosia virginiana may come from Greek and a place name: Tephrosia refers to the plant's ash-coloured, soft, hairy leaves ('tephros' means 'ash'), and virginiana means 'from Virginia'. So the name paints a clear picture of a grey, hairy little shrub from Virginia and helps you remember what it looks like.
