A New Species of <I>Anthurium</I> (Araceae) sect. <I>Urospadix</I> subsect. <I>Obscureviridia</I> from Espírito Santo, Eastern Brazil

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

“…Since the holotype was probably destroyed and there is no original illustration, we designate a neotype matching the characteristics in the original description. The chosen neotype is consistent with the morphologic features presented by Schott in the protologue and with the interpretation of Reitz (1957) and Valadares and Sakuragui (2014), who recognized all the A. gaudichaudianum varieties described by Engler as synonyms of A. gaudichaudianum. This species has great morphological and ecological amplitude and the synonymizations proposed by these authors were based on study of a large amount of material.…”

“…Therefore, it is necessary to designate a neotype that matches the description presented in the protologue. Like A. glaucescens, this name is traditionally recognized as a synonym of A. coriaceum (Croat, 1991;Valadares & Sakuragui, 2014; BFG-The Brazil Flora Group, 2015), and our choice of neotype followed the same principles used for that name. The vegetative features (e.g., leaf blade shape) and the ratio between spathe and spadix length seen in the chosen neotype are consistent with Engler's description in the protologue, and the specimen can be definitely identified as belonging to A. coriaceum by the features enumerated above under A. glaucescens.…”

“…Since the mid-20th century, various nomenclatural studies dealing with section Urospadix were performed by several authors (e.g., Croat, 1976Croat, , 1991Mayo, 1982;Coelho & Mayo, 2007), although a representative group of species belonging to subsection Obscureviridia Engl., found in eastern Brazil, still needs revision. This subsection is represented by 23 species in the Atlantic Forest (Valadares & Sakuragui, 2014), and it is characterized by chartaceous to coriaceous concolored blades, with barely visible primary lateral veins (Engler, 1898;Coelho et al, 2009;Valadares & Sakuragui, 2014). The latest in-depth study of species from this geographic region, published by Coelho and Mayo (2007), resulted in important nomenclatural and taxonomic changes in the genus, but it was restricted to subsection Flavescentiviridia Engl.…”

Beyond the typological characters: A morphometric approach to vegetative characters in Anthurium Schott (Araceae) species

“…Until now, all species of A. subsect. Obscureviridia had only been qualitatively evaluated using a few samples (Engler 1905;Valadares and Sakuragui 2014). No previous study has detailed the richness of qualitatively measured states for the species sampled by us.…”

“…obs.). These morphotypes show remarkable leaf plasticity and occur in several habitats, such as open (restinga, inselbergs) and forested (rainforest) areas (Mayo 1990;Valadares and Sakuragui 2014). The implementation of new methods that enables the recognition of the species of A. subsect.…”
