Novidades taxonômicas para Dilleniaceae brasileiras

Abstract

ResumoSão apresentadas novidades taxonômicas para Dilleniaceae da flora brasileira provenientes da revisão de dados bibliográficos e da revisão de herbários. Uma nova espécie, Davilla lanosa Fraga & Stehmann, é descrita, ilustrada e comentada acerca dos caracteres diagnósticos e das afinidades com outras espécies do gênero, sendo conhecida de duas localidades em Rondônia e uma ao sul do Amazonas, Brasil. É também estabelecida uma nova combinação e um novo status para Doliocarpus littoralis (Kubitzki) Fraga & Stehmann, baseado em uma subespécie de Doliocarpus major J.F.Gmel, e comentada a ocorrência de Neodillenia peruviana Aymard, um novo registro para a flora do Brasil. Palavras-chave: Davilla, Doliocarpus, Neodillenia, Brasil. AbstractUpdates on Dilleniaceae from the Brazilian flora are presented from bibliographic databases and herbaria collections. A new species Davilla lanosa Fraga & Stehmann is described morphologically and illustrated and its affinities to other species of the genus are discussed. The new species is known from two localities in Rondônia and one in southwestern Amazonas, Brazil. A new combination and new status for Doliocarpus littoralis (Kubitzki) Fraga & Stehmann is also proposed that assumes a specific level to be segregated from Doliocarpus major J. F. Gmel. The occurrence of Neodillenia peruviana Aymar is reported and commented on for Brazil.

Distribution and Conservation ofDavilla(Dilleniaceae) in Brazilian Atlantic Forest Using Ecological Niche Modeling

“…The AF is the center of diversity for Dilleniaceae with at least 36 species [22], with 12 of them belonging to the genus Davilla, which are liana plants and shrubs found in the forests and restingas. Although Davillas are few in number in the AF, some are among themost typical representatives into this biome, for example, Davilla rugosa [39].…”

“…The aim of this paper is to produce results on the geographical distribution of Davilla species (Dilleniaceae), an important genus which has numerous lianas representatives in several areas of Brazilian Atlantic Forest, including endangered species. Due to the fact that the Davilla has centers of diversity in the Atlantic Forest, especially in areas of coastal forests (Restingas), beyond the Cerrado and Amazon Rainforest [21,22], this group shows an interesting diversity in terms of geographical distribution of its species, including rare and vulnerable species, one of them is threatened with extinction [22,23] and, therefore, useful in conservation process. Thus, such information may be valuable in order to generate new information that will add to other efforts to learn the patterns of distribution and species richness of the Atlantic Forest.…”
