abstract = {The genus Scutachne (Poaceae, Paniceae) is revised. This American genus, which included two species from the Caribbean, was circunscribed utilizing morphological and molecular characters; in order to analyze both species of the genus, S. amphistemon and S. dura, a detailed study of the micromorphology of the upper anthecium and leaf anatomy, together with exomorphological characters, was performed; both species differ in vegetative and reproductive characters, such as blade distribution, ligules, presence of axillary inflorescences, upper glume and lower lemma consistence, lower palea consistence, presence of a lower flower, upper anthecium ornamentation, and presence of a rachilla extension; regarding the anatomical pattern, S. dura is a C4 PCK species, while S. amphistemon has C3, non-Kranz leaf anatomy. The phylogenetic analysis, based on molecular characters, also support these morphological differences. As a result, we concluded that Scutachne, as presently circunscribed, is a polyphyletic genus. Therefore, the genus Scutachne is here redefined and S. amphistemon is transfered to the new genus. Affinities of the new genus with other genera of Paniceae are also discussed.}
