Resumen

CHITTY, Francisco Delascio  y  NOZAWA, Shingo. Poa annua L. and Polypogon elongatus Kunth (Poaceae), two new exotic species to the flora of the Venezuelan Guayana Francisco . Acta Bot. Venez. [online]. 2010, vol.33, n.2, pp.357-361. ISSN 0084-5906.

Poa annua and Polypogon elongatus (Poaceae) are described as two new additions to the flora of the Venezuelan Guayana. These taxa are exotic to the bioregion, so they could represent a possible threat to the local biodiversity as invasive species. Actions for population management are proposed.
