Having the shape or form of a bean; bean-shaped.
From Latin bonus (good) or possibly from a shape-descriptor root, plus Latin -form (meaning 'in the shape of'). This is a rare technical term used in botany or anatomy.
This word is barely used in modern science—botanists just say 'bean-shaped' instead. It's a relic of an older, more Latin-heavy scientific vocabulary that preferred compounds over plain English descriptions.
