RESUMO

Otoba is the third largest genus of Myristicaceae in the Neotropics with 12 species, nine of them native to Colombia. Two new species from the department of Antioquia, O. scottmorii sp. nov. and O. squamosa sp. nov., are described and illustrated. Otoba scottmorii occurs in humid, lowland forests, while O. squamosa occurs in premontane forest. Previously, Otoba scottmorii was confused with O. acuminata (which here is considered restricted to Costa Rica and Panama), while O. squamosa was confused with O. gordoniifolia. The similarities and differences between these and other species are discussed.

RESUMO

Two new species of Protium (Burseraceae) are described and illustrated: Protium aguilariisp. nov., from the Pacific slope of the Osa Peninsula, Puntarenas Province, Costa Rica; and Protium hammeliisp. nov., from wet forests on the Caribbean slopes of Nicaragua and Costa Rica. In addition, Protium brenesiicomb. nov., is proposed as a new combination based on Trichilia brenesii, a name that was based on a specimen collected with flowers in the mountains near San Ramón, Alajuela Province, Costa Rica. It is compared with Protium costaricense, a similar species with which it has been confused for more than 90 years. Finally, illustrations and specimen citations are provided for all the aforementioned taxa, and some others with which they have been confused.

ResumenSe describen e ilustran dos nuevas especies de Protium (Burseraceae): Protium aguilariisp. nov., de la vertiente del Pacífico en la Península de Osa, provincia de Puntarenas, Costa Rica; y Protium hammeliisp. nov., de los bosques húmedos de la vertiente del Caribe en Nicaragua y Costa Rica. Además, se propone la combinación Protium brenesiicomb. nov., basada en Trichilia brenesii, un nombre que fue descrito en base en un ejemplar con flores recolectado en las montañas de San Ramón, provincia de Alajuela, Costa Rica. Se compara con Protium costaricense, especie similar, con la cual se confundió por más de 90 años. Finalmente, se proveen ilustraciones y listas de los ejemplares examinados para todos los taxones antes mencionados, y además algunos otros similares.
