摘要
Two new species of Miconia from northern Amazonia area described. Miconia amapaensis has been collected in the Brazilian state of Amapa and in nearby locations in northern Para and southern French Guiana. It has remarkable seeds, with both the appendix and seed coat covered with long papillae. Miconia forzzae has been collected on the Brazilian side of the Neblina Massif, in the Brazilian state of Amazonas, close to the border with Venezuela. It has 4-merous flowers, with a terete hypanthium, yellow stamens, the ovary apex with unbranched trichomes, and a punctiform stigma. This species may be endangered, considering its narrow distribution, and the fact that it was collected between 2000 and 2100 m elevation in an isolated mountain range with no neighboring mountains with similar height, but we assess its conservation status as "data deficient", due to a lack of knowledge on the situation of the populations and the number of individuals.
