DESCRIPTION:
Lawn burweed (spurweed) is a small winter annual often confused with pineapple-weed or brassbuttons. 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.
