centipede3-14b.jpg (144434 bytes) Weed Description:  A creeping perennial with stolons and distinctly compressed sheaths.  Centipedegrass forms a dense turf where established and for this reason is often planted as a lawn grass.   It is most commonly planted as a lawn grass in the southeastern United States from Virginia to Florida and west to Texas.
Leaves:  Approximately 15 to 30 mm long, 2 to 4 mm wide, and distinctly flat with a white midvein.  Leaves are without hairs except in the collar regions.  Leaf apexes are rounded.  Leaves are without auricles, and have a short membranous ligule that also has short hairs. centipedegrass11-16d.jpg (135774 bytes)

Roots:  Creeping stolons that are slender and branching.

Flowers:  The inflorescence is a single spikelike raceme that range from 3 to 5 inches in length.  The racemes are purplish in color, somewhat flattened, and have spikelets arranged in two rows. centipedegrass11-16.jpg (52861 bytes)
