DESCRIPTION:
Bristly oxtongue is a broadleaved biennial weed that is distributed
throughout California and is particularly troublesome in coastal
area orchards. The cotyledons (seed leaves) are broadly stalked and oval. The
first true leaves are more egg shaped and covered with coarse, barbed
and bristly hairs, which arise from blisterlike swellings. Mature
plants are 2 to 3 feet (60 - 90 cm) tall with angled stems and
covered with harsh, barbed, stiff hairs. Yellow flower heads are
borne at the top of stems. The petals are toothed.
