A new epilithic bromeliad (Stigmatodon, Tillandsioideae) from Pedra dos Três Pontões, Espírito Santo, Brazil, with an emended combination for the genus

Background and aims – Stigmatodon (Bromeliaceae) is a monophyletic genus currently comprising 33 species, all endemic to rocky outcrops, mainly inselbergs, from the Atlantic Forest and campos rupestres of the Espinhaço range, Brazil. Material and methods – Our fieldwork in the inselbergs of the Atlantic Forest of the state of Espírito Santo led to the discovery of a new Stigmatodon species with a tubo-laciniate stigma type. Standard herbarium taxonomy practices were adopted to study the novelty. Morphological data were obtained from herbarium specimens and fresh material collected in the field. Key results – Stigmatodon lemeanus is here described and illustrated. Diagnostic characters and affinities of the new species are discussed, accompanied by notes on its ecology, geographic distribution, and conservation status. A key to the species of Stigmatodon from Espírito Santo state is provided. The novelty is similar to S. goniorachis from coastal inselbergs of Rio de Janeiro and S. attenuatoides, another inselberg endemic from southern Espírito Santo. Stigmatodon lemeanus is preliminarily assessed as Vulnerable (VU) according to the IUCN Red List criteria. Additionally, we present a new combination of Tillandsia oligantha in Stigmatodon, correcting a nomenclatural error

Davilla hirsuticarpa (Dilleniaceae), a new species from the Atlantic Forest of Brazil

Background – Davilla (Dilleniaceae) currently comprises 28 species and is distributed throughout the Neotropics. Extensive fieldwork conducted in the Atlantic Forest of the Brazilian states Bahia, Espírito Santo, and Rio de Janeiro resulted in the discovery of a new species of Davilla, described and illustrated in this paper.Methods – Herbarium collections including type specimens were consulted for identification and compared to the new species. Morphological data of the new species were obtained through the study of herbarium specimens as well as of live specimens observed in the field.Key results – Davilla hirsuticarpa Fraga & Aymard, a new species endemic to the Atlantic Forest areas, is here described and illustrated, along with comments on its geographical distribution, ecology, and conservation status. The new species resembles D. bahiana Aymard and D. cuspidulata Mart. ex Eichl., from which it differs by hirsute carpels. In accordance with the categories and criteria of the IUCN Red List, it could be considered as Vulnerable (VU). A new key to all species of Davilla sect. Davilla is provided

Florística e ecologia das Orchidaceae das restingas do estado do Espírito Santo,

RESUMO Este trabalho teve como objetivo inventariar as Orchidaceae das restingas do estado do Espírito Santo, detectar as formas de vida e proceder a uma análise da similaridade entre as formações vegetais das restingas, através da flora orquidológica. As coletas de material botânico foram feitas ao longo de todo o litoral sendo incluídas as coleções dos herbários CVRD, MBML e VIES. Foram identificados 73 táxons, sendo 71 espécies, dentre estas uma nova para ciência, e dois híbridos naturais. O maior número de espécies foi encontrado em Epidendrum (7) e Pleurothallis (6). Foram encontrados 31 táxons holoepífitos, 28 táxons terrestres, 12 táxons epífitos facultativos e dois táxons hemiepífitos. Das 10 formações vegetais de restinga as Orchidaceae estiveram representadas em oito. A floresta arenosa litorânea apresentou 58 táxons, seguida pela formação aberta de Clusia (31), formação aberta de Ericaceae (20), floresta periodicamente inundada (14), formação póspraia (13), formação Palmae (10), formação brejo herbáceo (3) e formação praial graminóide (2). A maior similaridade florística, utilizando o índice de Sorensen, foi encontrada entre as formações arbustivas fechadas (pós-praia e Palmae) seguidas pelas formações arbustivas abertas (de Ericaceae e de Clusia). Estes dois grupos se ligam, com menor similaridade às formações florestais, enquanto as formações herbáceas são as mais dissimilares

Novidades taxonômicas para Dilleniaceae brasileiras

Resumo São 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

Nomenclatural revision and typification of extra-Amazonian Tachigali (Leguminosae - Caesalpinioideae)

Background and aims – The neotropical genus Tachigali comprises about 75 recorded species, including names described in Sclerolobium, synonymised in 1993 in Tachigali based on morphological, molecular, and anatomical characters. Most species are found in northern South America and the Atlantic Forest. However, some species are exclusively found in the savannas of central Brazil (Cerrado), Bolivia, and Paraguay. The Tachigali species from northern South America and Central America has already been revised. However, the extra-Amazonian Tachigali species were not correctly typified due to the impossibility of examining all syntypes. Therefore, the present work aims to present the nomenclatural review of the extra-Amazonian species of Tachigali. Material and methods – The list of accepted extra-Amazonian Tachigali names and their basionyms was made and verified through online databases. The original descriptions were consulted online or in the Rio de Janeiro Botanical Garden Library. The type specimens were examined in virtual herbaria and through visits to the B, IAN, G, K, M, NY, P, R, RB, US, and W herbaria. The International Code of Nomenclature of algae, fungi, and plants was followed for the type designation and nomenclatural notes. Key results – The nomenclatural review was carried out for 32 names. A total of 15 lectotypifications, representing 12 Tachigali species, and a new combination for Tachigali rubiginosa is proposed herein. Furthermore, the nomen dubium Sclerolobium macrophyllum is presented. Conclusion – Our study provides the nomenclatural review for the extra-Amazonian Tachigali species, including notes about the type materials, collectors, and authors of all species names, in addition to the holotype and lectotype images
