Explanation:

Ans. Para grass

Native to tropical Africa, para grass is a creeping, perennial grass that can grow in both semi-aquatic situations and on deep soils in non-swampy areas. It was introduced to Queensland around 1880 to reduce soil erosion along the banks of waterways.

Para grass has been used in tropical locations as a fodder species, especially as a ponded pasture in beef production. In Queensland, para grass is now a common weed, especially in many cane-growing areas. It is an aggressive invader and can displace native plants.
