Having nine stamens or male reproductive parts; used in botanical classification.
From Greek 'ennea' (nine) + 'andros' (male), with '-ous' as a common English adjectival suffix. This variant of 'enneandrian' is used interchangeably in botanical Latin and English.
Botanists had to choose between '-ous' and '-ian' endings for the same concept, and different regions/scientists preferred different versions—a reminder that scientific terminology wasn't imposed from above but evolved organically through usage and preference.
