Common names
Bull rushes, Egyptian paper plant, Nile grass, Paper reed.
A large, long-lived, reed-like plant with upright, three-sided, stems growing 2-4 m tall. It also produces thick creeping underground stems. Its leaves are reduced to sheaths at the base of the stems. Its seed-heads are large and much-branched structures that are subtended by 4-10 relatively small leafy bracts. These seed-heads have numerous thin, hair-like, branches (10-30 cm long) bearing clusters of flower spikelets. Its very narrow flower spikelets (6-15 mm long and about 1 mm wide) contain up to 18 tiny flowers.
Impact
Impact
Papyrus (Cyperus papyrus) has spread from cultivation as a garden and pond plant and invaded the margins of permanent water bodies in south-eastern Queensland and northern New South Wales. This rapidly growing species can spread to cover areas of open water, preventing other aquatic species from growing, and reducing light levels to submerged native plants. It is regarded as a minor environmental weed or potential environmental weed in parts of Queensland and New South Wales. For example, infestations were recently targeted for removal from Seaham Swamp Nature Reserve, at Port Stephens on the mid-north coast of New South Wales., Papyrus (Cyperus papyrus) is also a weed of deep water channels in the Warriewood Wetlands and a common weed in the Lakes of Cherrybrook Reserve in suburban northern Sydney.
