STRUCTURE |
|
One of the one or more constituent members of a corolla; colored and showy in many taxa, inconspicuous in size and/or color in others; may be distinct or else connate with one or more others, and/or may be free or else adnate to one or more other floral structures. |

|
pseudoterminal |
|
insertion |
|
Only apparently terminal; originally subapical but displaced toward the apex by differential growth during development. |
