A new species of Miconia (Miconieae, Melastomataceae) from Northwest Ecuador

A new species, Miconia yeseniae , is described and illustrated. The species is part of the Amblyarrhena section and is distinguished from others of the genus by the large (2–2.5 cm long) pink petals, the well-developed outer calyx teeth (4.9–5.1 mm long) and the 10-angular ovary. The most related species are Miconia glandulistyla , M . floribunda , M . codonostigma , M . glandulistyla and M . grandiflora . The new species reaches 8 m in height and is known only from the type locality, on the slopes of Cerro Golondrinas, on the Andean flanks of the northwest of Ecuador, in the humid forest.
