[FMP-field: image]

This is a bipinnately compound leaf of Delonix regia, royal poinciana.

A bipinnately compound leaf is divided twice: each leaflet is subdivided into smaller leaflets. The pinna (pl. pinnae) is the name of the first division. The pinnule is the name of the ultimate division. The pinnae are borne on the primary rachis, while the pinnules are borne on the secondary rachis.
