DESCRIPTION:
Flixweed, a winter or early spring annual broadleaf plant sometimes called tansy mustard, occurs in waste areas, fields, roadsides, and ditchbanks in central and eastern California. Seedlings have long and narrow leaves on fine haired stalks. A stub remains when cotyledons (seed leaves) are shed. The first pair of true leaves appear to be opposite. Somewhat thick, the leaves are alternate and covered with white downy, star-shaped hairs. Mature plants, up to 2 feet (60 cm) tall, have yellow flowers and finely dissected leaves. Erect branches have long, flowering stems with seed pods about one inch (25 mm) long.
