Belonging to or characteristic of the Coelastraceae family of plants.
From Coelastraceae with the adjectival suffix -aceous, used in botany to denote membership in a plant family (similar to rosaceous, referring to the rose family).
The -aceous suffix is botany's special marker meaning 'family member'—it's how scientists quickly signal 'this plant belongs to that family,' making it easier to predict shared features without naming the whole plant.
