Poa laegaardiana, a new species from Ecuador (Poaceae, Pooideae, Poeae, Poinae)

Abstract. Poa laegaardiana sp. nov., is described and illustrated. The new species was found growing on sandy, volcanic soil in Festuca-Calamagrostis dominated grasslands southwest of Ambato and 2.2 km from Fecundo Vela in Provincia de Bolivar. The new species is morphologically similar to Poa gigan...

description Abstract. Poa laegaardiana sp. nov., is described and illustrated. The new species was found growing on sandy, volcanic soil in Festuca-Calamagrostis dominated grasslands southwest of Ambato and 2.2 km from Fecundo Vela in Provincia de Bolivar. The new species is morphologically similar to Poa gigantea but differs in having glumes 3/4 to 7/8 as long as the adjacent lemmas, a callus with a sparse, short, dorsal tuft of woolly hairs, culms 50–72 cm tall and spikelets 4.1–4.8 mm long. In addition, we include a key to the narrow-spikelike panicled species of Poa in Ecuador.
