'angulodentate' originates from Latin, combining 'angulo-' from 'angulus' meaning 'angle' and 'dentate' from 'dens, dentis' meaning 'tooth.'

'Angulodentate' formed in modern scientific English from the Latin combining form 'angulo-' + English/Neo-Latin 'dentate,' yielding the descriptive adjective used in botany and zoology.

Initially, it meant 'toothed with angular points,' and this meaning has remained consistent in technical usage.
