which grow very long, foliaceous, rigid, wiry hraoteoe. Leaves very numerous, squaiTose, concave ahove, keeled below
towards the long harsh points, margins cutting, with minute teeth. Mmering part of culm a span long, of confluent
clusters of sessile red-brown spikelets, occupying one side only of the cGm. and spirally arranged. Brac-
