Notes on Meaning

• Specificity: In botanical and regional contexts (especially the western U.S.), "yellow pea" is a precise term for a particular herb. In general conversation, it could be interpreted more loosely as any pea plant with yellow flowers, but the primary dictionary definition refers to the specific western U.S. herb.
