A new species called Phyllanthus pterocaulis from the state of Goias, Brazil is described and illustrated in this paper, with discussions on its geographic distribution, morphological relationships, and systematic position. The species is similar to other species in terms of morphology, but differs in several characteristics. Additionally, images, conservation status, distribution maps, anatomical descriptions, and differentiation key are provided.
A new species from the state of Goias, Brazil, Phyllanthus pterocaulis, is described and illustrated, with comments on its geographic distribution and environmental preferences, phenology, morphological relationships, and systematic position. It is morphologically allied with Phyllanthus avicularis, P. heliotropus, and P. hyssopifolioides, but differs from all of them by a set of characters related to cymules sex, presence and types of trichomes on leaves and stems, leaf consistency, numbers of sepals in flower of both sexes, integrity of stamens, capsules and seeds. Additionally, we provide images of the new species in the field, conservation status, mapped distribution, the anatomical description of its stem and leaves, and a key to differentiate it from the other similar species belonging to Phyllanthus sect. Loxopodium occurring in Brazil. The new species is one of the few in the genus that occurs in shaded environments in seasonal dry forests within the Cerrado biome.
