Summary
[edit]DescriptionBothriochloa macra habit4 (14312240706).jpg |
In Uralla park, Northern Tablelands NSW. Native, warm-season, perennial, tufted grass to 100 cm tall, with (virtually) hairless stem nodes. Flowerheads are subdigitate, with 3-4 erect branches that are pressed together and bare at their base for a short distance. Spikelets are paired, with an unstalked awned spikelet and a stalked unawned spikelet; the awned spikelet is 5-7 mm long, hairy and has a pit. Flowers from late spring to autumn. Mostly found on undulating country with low to moderate soils that are not extremely acidic, but it also occurs on fertile soils (e.g. basalts). Native biodiversity. Increases in abundance with over-grazing and readily colonises bare and disturbed areas. Responsive to increased fertility, but grows well in unfertilised areas. Not very palatable, although quality is moderate if plants are fertilised and kept short (hard to achieve). Quality is low when stemmy or when frosted. Yields can be high, but a large proportion is usually stem. If there is dense clover in late spring, it can thin red grass dramatically. To maintain quality, graze to minimise stem development. |
