| 説明 | Flowers as in all grasses are greatly reduced.Native, yearlong-green, perennial, slender, tufted to mat-forming, C3 grass; to 60 cm tall and with short, slender rhizomes. Leaves are flat, bright green to dark green, 1-12 mm wide, smooth or rough and hairless to hairy. Leaf tips are usually notched and small hairy auricles may occur at the base of the leaf. Flowerheads are weeping, narrow panicles or racemes to 15 cm long. Spikelets aregreen and 3-flowered; glumes are reduced to minute scales or hairs; 2 lower sterile florets each have a straight green awn; upper fertile floret is awnless. Found in many habitats. Although usually a minor component of dry open native-natural pastures, it can become dominant in shaded, moister areas, such as along forest edges and under she-oaks on river flats. Very tolerant of acid soils, exchangeable aluminium and drought. |
