Resumen:
Taxonomic features of species of Panicum section Parviglumia
are reviewed and compared with those of other taxa in tribe Paniceae. The new
genus Morronea is proposed on the basis of morphological characters,
i.e., plants growing at forests edges, with membranous-ciliate ligules, lower
glume reduced, 1/6 to ¼ the spikelet length, lower palea and lower flower
absent, and upper anthecium indurate with simple papillae and conspicuous
macrohairs all over its surface, and chloroplast ndhF sequences to
include six species ranging from Mexico to Argentina. The new
combinations: Morronea arundinariae, M. cayoensis, M. guatemalensis, M.
incumbens, M. parviglumis, and M. trichidiachnis are
proposed and the new genus is compared with other genera of the tribe Paniceae.
