A taxonomic or descriptive term referring to organisms or plants characterized by dicyclic structures or arrangements.
From 'dicyclic' + '-a' (Latin neuter plural ending). This appears to be a scientific Latin form used in older botanical classifications.
Scientific Latin endings like '-a' are fossils of how scientists named things before English standardized the language—botanical terms keep this Latinate poetry alive!
