(typical of mustards), with each flower having 4 white petals. Flowers
are small (1 to 3 mm across).

Seed pods: Flattened, football shaped,
about 3 mm long. These can be used to distinguish this plant from
Arabidopsis and Shepherd's purse. |
|
Notes: This plant is small, inconspicuous,
and typically flowers and disappears before April. Therefore, it is
not a plant that requires any attention in terms of weed control. It
is included on this website for thoroughness, because it does occur often
and in high numbers in cultivated fields of western Oregon.
