DESCRIPTION:
Lawn burweed (spurweed) is a small low growing winter annual broadleaf plant often confused
with pineapple-weed
or brassbuttons. The cotyledons (seed leaves) are oblong to narrowly
oval and fused at the base. The first leaf pair is lance shaped, often sparsely haired, with long tapered bases.
Subsequent leaves are deeply dissected and covered with fine hairs. Stems are branched
and are dark-colored or purple-spotted. Seed, when formed, appears
in a small, spined bur that you can feel readily when you press
a clump with your hand. The flower heads are inconspicuous in the
leaf axil and have small spines.
