From hexandria + '-ic' (a suffix forming adjectives). The adjectival form used to describe plants that fit into the Hexandria classification.
A hexandric flower might seem like an obscure botanical detail, but for 18th-century naturalists it was the equivalent of finding the perfect filing system—six stamens made a plant instantly recognizable and classifiable at a glance.
