Abstract

Parodiolyra is a member of Olyreae, a tribe of herbaceous bamboo species within the Poaceae. The genus has five species, four of which were previously regarded as belonging to Olyra L. Parodiolyra has a Neotropical distribution and only two species occur on forests in Eastern Brazil: P. micrantha (Kunth) Zuloaga & Davidse and P. ramosissima (Trin.) Soderstr. & Zuloaga, the first widely distributed in the Neotropics while the second is endemic to the state of Bahia. Leaf anatomy of the two species was analysed with the aid of an optical microscope. The objective was to describe the microscopic characters and evaluate if they can be useful for the taxonomy of the genus. The observed anatomical structures did not differ from other genera of herbaceous bamboos, however some characters, both from the mesophyll and the epidermis, were useful to delimit the two species.Parodiolyra está inserido em Olyreae, tribo de bambus herbáceos pertencente à Poaceae, e apresenta cinco espécies, sendo quatro delas previamente consideradas como parte de Olyra L. O gênero tem distribuição neotropical e apenas duas espécies ocorrem nas florestas do leste do Brasil: P. micrantha (Kunth) Zuloaga & Davidse e P. ramosissima (Trin.) Soderstr. & Zuloaga; a primeira, amplamente distribuída no Neotrópico, e a última, endêmica do Estado da Bahia. A anatomia foliar dessas duas espécies foi analisada através de microscopia de luz, com o objetivo de descrever seus caracteres microscópicos e avaliar se os mesmos podem ser úteis para a taxonomia do gênero. A estrutura anatômica observada não se diferencia daquela dos demais gêneros de bambus herbáceos, mas alguns caracteres do mesofilo e da epiderme foram úteis para delimitar as duas espécies.
