“…1 mm long) than those of D. leucotricha. The lower leaf side of D. ruboides, species recorded for the Amazon and Atlantic Forests of Brazil (Bazante & Alves 2021), is sparsely covered with stellate scales (vs. rather densely covered with stellate hairs), and it has broadly ovate sepals with an obtuse apex (vs. ovate-triangular sepals with an acute apex) that can distinguish it from the new species.…”

A new species of Annonaceae, Duguetia leucotricha M.L.Bazante & Maas, from lowland to submontane forests of southern Bahia, Brazil, is described. It differs from other species of the genus mainly by the dense greyish white stellate hairs on vegetative and reproductive structures, rather widely-spaced flowers, the large bract in the upper part of the well-developed pedicel, sepals and petals almost equal in length, and the few-carpellate fruits with rounded apex of the areoles. Commentaries concerning its morphological aspects and relationships of affinity, geographic distribution, conservation status and photos are provided, as well as a key to all Atlantic Coastal Forest species of Duguetia.

“…Although the majority of the species inhabit the Amazon basin, ca. 50 species, the Atlantic Coastal Forest is also an important center of diversity of the genus, with 14 of its 18 species being endemic to this domain (Lobão & Bazante 2020;Bazante & Alves 2021).…”

The South American Atlantic Forest is a biodiversity hotspot, and a relevant area for conservation due to its high level of endemism and great loss of habitat. One of its endemic taxa is the genus Hornschuchia (Annonaceae), including 12 species that occur from the State of Rio de Janeiro to Pernambuco in Brazil. The last taxonomic treatment of Hornschuchia was carried out 27 years ago. Since that time, two new species have been described and new specimens of known species have been collected, expanding our knowledge about the morphology and distribution of the genus. Hornschuchia, as an endemic genus in a threatened environment, deserves special attention. For this reason, we updated the taxonomic treatment of Hornschuchia, including the recently described species in the key, preparing illustrations, updating the descriptions of the species, clarifying and correcting information regarding the historical and type collections, providing preliminary conservation statuses, and analyzing patterns of endemism and richness for the genus. One species is preliminarily assessed as Critically Endangered, nine are Endangered, one is Vulnerable and one is of Least Concern. The coast of Bahia is a priority place for conservation for Hornschuchia as its center of species diversity.
