Abstract

RODRIGUES, Rodrigo S.  and  FILGUEIRAS, Tarciso S.. First record of Isachne ligulata (Poaceae: Micrairoideae) in Brazil and a key for the Brazilian species of the genus. Acta Bot. Bras. [online]. 2016, vol.30, n.4, pp.700-704. ISSN 0102-3306.  http://dx.doi.org/10.1590/0102-33062016abb0269.

While performing a taxonomic revision of the Neotropical species of Isachne, analysis of herbarium collections revealed the occurrence of Isachne ligulata in Brazil. We provide a description and the first illustration of I. ligulata, along with comments on its ecology, distribution and morphological affinities with related South American species. We also provide an identification key for the Brazilian species of the genus.

Keywords : distribution; grasses; Isachneae; Neotropics; South America.
