Duguetia rolimii (Annonaceae), a new large tree species from the Atlantic Forest of Espírito Santo, Brazil

A new species of Duguetia from Reserva Natural Vale, in the Atlantic Forest of the Brazilian state of Espírito Santo, is described and illustrated, and an updated key to the Duguetia species from this state is presented. Duguetia rolimii is known only from two large trees, restricted to the municipality of Linhares. It resembles D. sooretamae in having young twigs densely covered with stellate scales, narrow and shiny leaves with similar dimensions, and fruits with more than 200 fertile monocarps. Nevertheless, these two species can be distinguished from each other mainly by the type of vegetation where they occur, plant size, the density of stellate scales at the lower side of the leaves, the angle between the primary and secondary leaf veins, the shape of the flower buds, length of the upper bract, the shape of the fertile monocarps and indument of the areoles. Comments on distribution, conservation status and field photos of the new species, and comparisons with other related species are provided.
