DESCRIPTION:
Dallisgrass is a perennial grass. Its rapid growth and profuse
seed production enable it to quickly invade garden or orchard
areas.
The ligule is firm and membranous with a few spreading hairs at
the margins. There are no auricles. The mature plant forms loose
bunches, 1 to 4 feet (30 - 120 cm) high. The flower head consists
of 3 to 6 spikes
that
arise apart on the stem and often droop. The leaf sheath is
somewhat
flattened; at the base, it is hairy, often tinged red, and usually
inflated. The
underground shoots are
fairly short with areas that appear as concentric rings.
