Material examinado:— BRASIL. Maranhão: Alto Parnaíba, Parque Nacional das Nascentes do Rio Parnaíba , subida da Galiléia, 10° 03’8” S, 46° 22’ 38” W, 17 March 2023, M. C. C.

Geographical distribution: Copaifera coriacea is not endemic to Brazil ( POWO 2024). In the country, it is found only in the states of Bahia and Piauí, within the Cerrado and Caatinga domains (Costa 2020; Flora e Funga do Brasil 2024). In the present study, Copaifera coriacea was identified for the first time in the state of Maranhão, in rocky cerrado and cerradão areas ( Fig. 2E, B ).

Note: Copaifera coriacea ( Fig. 7 A ) can be recognized by its shrubby habit, leaves with 2-3 pairs of elliptical, leathery leaflets, flat margins, glabrous indumentum on both sides of the leaflets, and paniculate inflorescence, valvas of legume lignose and seed arilate.
