<I>Barjonia furlanii</I> (Apocynaceae, Asclepiadoideae), a New Species from the State of Minas Gerais, Brazil, and a Key to Genus

Abstract

^This paper provides descriptions and illustrations of a new species, Barjonia furlanii (Asclepiadoideae, Apocynaceae), from Serra da Canastra National Park, in the state of Minas Gerais, Brazil. This species is similar to S. laxa, especially in its frondose thyrsoid inflorescence, compound corona, and linear leaves. It is, however, distinguished from B. laxa by intemodes (up to 4 cm long), peduncles (4.2-5mm long) and much shorter pedicels (4-6 mm long), erect leaves, attenuated at the base, and partial inflorescences that alternate with 2-4 flowers. B. furlanii is proposed for Endangered status under IUCN guidelines (EN B2abiii), and a key to all Barjonia species is included in this study.

Increasing the known floristic diversity of Brazilian inselbergs: two new species of Mandevilla (Apocynaceae) from Espírito Santo

“…Apocynaceae are highly diverse in Brazil, with around 760 species reported (Koch et al 2015). In the last fifteen years, as a result of floristic, taxonomic or phylogenetic studies, several endemic species and genera have been described (e.g., Konno et al 2006;Sales et al 2006;Rapini & Farinaccio 2010;Rapini & Pereira 2011;Farinaccio 2013;Espirito Santo et al 2018 a;b;Scudeler et al 2018;Pereira et al 2019). Mandevilla (apocynoids, Mesechiteae) comprises ca.…”

Palynological investigation of lactiferous flora (Apocynaceae) of District Rawalpindi, Pakistan, using light and scanning electron microscopy

“…Apocynaceae was further divided into five subfamilies, that is, Rauvolfioideae (comprehensively distributed in 915 species 83 genera/10 tribe), Apocynoideae (comprehensively 822 species 80 genera/eight tribes), Periplocoideae (Eastern Hemispherean 33 genera), Secamonoideae (distributed in Eastern Hemispherean eight genera), and Asclepiadoideae (Ecumenical distribution in four tribes/172 genera; Endress & Bruyns, ). Asclepiadoideae are now sighted as the biggest subfamily of Apocynaceae (Farinaccio, )…”

“…Floristic studies carried out over the last 15 years in this part of Minas Gerais state (Nakajima & Semir 2001;Romero & Martins 2002;Farinaccio & Mello-Silva 2004;Scudler 2004;Pontes & Mello-Silva 2005;Filardi et al 2007;Carvalho-Silva & Guimarães 2009;Hemsing & Romero 2010;Morokawa et al 2013), suggest that the region has a high number of endemic species from different families of Angiosperms (Romero & Goldenberg 1999;Romero & Nakajima 1999;Assis 2002;Romero & Guimarães 2005;Cavalcanti 2007;Batista & Bianchetti 2010;Chautems et al 2010;Feres 2010;Dutra & Garcia 2013;Farinaccio 2013). Melastomataceae is considered one of the most representative families in campos rupestres of this region with more than a hundred species (Romero & Martins 2002;Silva & Romero 2008), from which at least five are endemic (Romero & Goldenberg 1999, Romero 2000, Romero & Guimarães 2005.…”
