Abstract
AbstractCopaifera L. is a woody legume genus with 42 species that produce valuable terpenoid oleoresins used in medicine and industrial activities. Copaifera belongs to the Detarieae (Detarioideae) and is part of a clade together with five other genera. We describe the seedling morphology of Copaifera pubiflora Benth. based on plant architectural analysis to shed light on its post‐seminal shoot development. Seeds of this species were collected from a wild population in Roraima State, Brazil. Seedlings of C. pubiflora have preformed shoots with determinate and rhythmic growth. Each growth unit has two reduced leaf scales that correspond to a pair of prophylls followed by two or three scale‐like stipules and one distal eophyll. Besides, C. pubiflora has a monochasial sympodial branching with delayed branches. Current evidence indicates that most Copaifera species, including C. pubiflora, have phanerocotylar, epigeal, reserve seedlings with a cataphyll‐free epicotyl and scale‐like structures on the first internode after the epicotyledonary axis. Based on the available data, a comprehensive view of Copaifera seedlings from both the Old and New Worlds is also presented.
