Notes on Meaning

This is a specialized scientific term. Its primary meaning is taxonomic, referring to a specific clade of leguminous plants. Its usage is almost entirely confined to botanical science and historical scientific texts. The "alternative name" aspect of its definition is key, indicating it is not the primary classification in current use.
