Pimenta paganii (Krug & Urb.) Flickinger (in Flickinger et al . 2020 ). Myrcia paganii Krug & Urban (in Urban 1894–1895: 587). = Myrcia margarettae (Alain) Alain (in Liogier 1985: 328 ). Eugenia margarettae Alain (in Liogier 1963: 190 ), syn. nov . Type :— PUERTO RICO . Doña Juana, Toro Negro Mountains, in dense wood, 10 July 1962 , Liogier 9400 ( holotype NY [image!]). Analysis of the type material of Myrcia margarettae indicates strong similarity with Pimenta paganii , especially the tomentose and ferruginous indumentum covering twigs, inflorescences and flowers, leaf form and venation, and pentamerous flowers arranged in few-flowered dichasia. Based on these features, Myrcia margarettae is here considered a synonym of Pimenta paganii . Leaves of juvenile plants are larger with an acute apex vs. smaller and rounded in immature individual, which explains the difference in leaf shape between the sterile type of Myrcia paganii and the fertile type collection of M. margarettae (Flickinger, pers. obs.).
