'banded-leaved' originates from Modern English as a compound of 'banded' + 'leaved'. 'Banded' is the past participle/ adjective form of 'band' + '-ed', and 'leaved' is the adjective form derived from 'leaf' (meaning 'leaf' or 'having leaves').

'band' comes from Old Norse and Old English roots (Old Norse band, Old English bænd) from Proto-Germanic *bandaz meaning 'a strip, bond, or tie'. 'Leaf' comes from Old English 'lēaf' (Proto-Germanic *laubaz). The compound construction combining an adjectival past participle with 'leaved' (e.g., 'banded-leaved') is a Modern English descriptive formation used in botanical and descriptive contexts.

Initially the elements meant 'a band/strip' and 'leaf' separately; the compound evolved to mean specifically 'having leaves marked with bands or stripes' as a fixed descriptive term in botanical usage.
