APHANELYTRUM PERUVIANUM (POACEAE: POINAE): A NEW SPECIES FROM PERU

Aphanelytrum peruviamim Sanchez Vega, P.M. Peterson, Soreng & Laegaard, sp. nov., is described and illustrated. The new species occurs on rocky sites near Cerro Akumullca in Cajamarca, Peru and represents the second known species ascribed to Aphanelytrum. Aphanelytrum peruvianum differs from A. procumbens by having nerved glumes (1-2 mm long), narrow leaf blades (0.2-1.2 mm wide), shorter culms (14-24 cm tall), shorter internodes (3-13 mm long), shorter lemmas (2.2-3.5 mm long), and shorter anthers (2-2.9 mm long). A key and table comparing the salient features distinguishing A. peruvianum and A. procumbens is given. RESUME
