| 説明 | Introduced warm-season perennial tufted C4 grass with spreading crowns; stems are fine, hairless and to 1.5 m tall. Leaves are grey-green, 6-20 mm wide and nearly hairless. Flowerheads are subdigitate with 4-14 racemes usually in 3 whorls, about 7-17 cm long and brownish-purple when immature and brownish grey when mature. Spikelets are paired, 2-flowered, shortly-hairy and 2-4 mm long. Flowers in summer. A native of Africa, it is a sown species in the north with one variety Premier. Grows on a range of soil types, but is best suited to light-medium textured low-fertility soils. Good drought and frost tolerance, but is sensitive to waterlogging. Recruits well on light-medium textured soils. Can produce some growth in winter and commences growth in late winter-early spring, much earlier than most other tropical grasses. Very palatable, has low oxalate levels (i.e. suitable for horses) and tolerates close grazing. |
