Three New Species of Anthurium (Araceae) from the Atlantic Forest of Rio de Janeiro, Minas Gerais, and Espírito Santo, Brazil

Abstract

This study describes and illustrates three new species of Anthurium Schott sect. Urospadix Engl. subsect. Obscureviridia Engl. from the Atlantic Forest of southeastern Brazil: A. temponiae Nadruz & Theófilo, A. martinellii Nadruz & Theófilo, and A. erythrospathaceum Nadruz & Theófilo. Information about their conservation status within priority areas of the Atlantic Forest is included, together with distribution maps and an updated key to the species of subsection Obscureviridia.

Vascular plants on inselberg landscapes in Espírito Santo state: bases for the creation of a protected area in southeastern Brazil

“…A new species of Araceae (Anthurium genus) recorded during fieldwork (voucher: J. M. C. Covre 93), is in description phase. On the other hand, Alcantarea patriae Versieux & Wand (Versieux & Wanderley, 2007), Anthurium martinellii Nadruz & Theófilo (Coelho & Valadares, 2019), Coleocephalocereus uebelmanniorum (Braun & Esteves) Braun, Esteves & Hofacker, Pitcairnia azouryi Martinelli & Forzza (Martinelli & Forzza, 2006), and Stigmatodon attenuatoides (Couto, Manhães & Costa, 2020) were described from collections obtained in the PAC. Of these species, Alcantarea patriae, Anthurium martinellii, Coleocephalocereus uebelmanniorum and Stigmatodon attenuatoides are endemic to the inselbergs of Jerônimo Monteiro and Cachoeiro de Itapemirim.…”

Marantapilosissima (Marantaceae), a new species from Brazilian Atlantic Forest

“…State, already (Baumgratz et al 2014) and continue to discover new records and new species, many of them within protected areas (Calazans et al 2015, Coelho and Valadares 2019, Farias et al 2019, Rollim and Trovó 2020, Fernandes and Faria 2022. This asserts the key role of conservation units of integral protection for the maintenance of Rio de Janeiro's biodiversity.…”

“…In this context, initiatives such as the Catalogue of Rio de Janeiro's Flora are of great importance. Botanists have cataloged 8160 species for Rio de Janeiro State, already (Baumgratz et al 2014) and continue to discover new records and new species, many of them within protected areas (Calazans et al 2015, Coelho and Valadares 2019, Farias et al 2019, Rollim and Trovó 2020, Fernandes and Faria 2022, Fernandes et al 2022). This asserts the key role of conservation units of integral protection for the maintenance of Rio de Janeiro's biodiversity.…”

Nomenclatural Novelties in Anthurium sect. Urospadix subsect. Obscureviridia from the Brazilian Atlantic Forest

“…The neotype we selected definitely belongs to A. coriaceum, as shown by features including a short stem, coriaceous leaf blade, non-revolute spathe, and more than nine flowers per spiral. These last two features are the best for distinguishing A. coriaceum from other Obscureviridia species (see Coelho & Valadares, 2019).…”
