In botany and zoology, describing something that has a wide open gap, gape, or opening, especially a flower with petals that don't fully close.
From Latin 'hiāns' (gaping, from 'hiāre' meaning to gape). Used in scientific classification to describe organisms with characteristic openings.
Some flowers are 'hiant'—they never fully close their petals like other flowers do, which means they're always ready for pollinators to visit, whether it's sunny or cloudy.
