Miscanthus and Erianthus, nearly allied to Saccharum, are tall reed-like grasses, with large silky flower-panicles, which are grown for ornament.
In the swampy lands of the upper Nile it forms, along with a species of Saccharum, huge floating grass barriers.
In the sugar-cane (Saccharum) and several allied genera the separating joints of the axis bear long hairs below the spikelets; in others, as in Arundo (a reed-grass), the flowering glumes are enveloped in long hairs.
Saccharum officinarum (sugar-cane) (q.v.).
This is soon impregnated with the seeds of the Saccharum spontaneum and other grasses that have been partly brought by the winds and partly deposited by the water.
