Etymology

Digitalis, a derivation of 'digit' (as in 'fingered', 'hand-like', or 'lobed from one point'), meaning 'Finger-Bonnet' or 'Fingerstall', which comes from Leonhart Fuchs' translation of the German name for Digitalis, 'Fingerhut', literally meaning 'Finger-Hat'. Davisiana is named for Peter Hadland Davis.
