is a species of willowherb
known by the common name selfing willowherb
. This plant is endemic
to central California
where it is a resident of vernal pools
and mudflats. This is a small annual with fuzzy pointed green leaves. Some of the leaves have hairs which are knobby and gland-tipped. The flowers are usually cleistogamous
, that is, they self-pollinate without opening. Some of the flowers do open to reveal pinkish-purple to nearly white, deeply notched petals. The fruit is a tough four-sided capsule about a centimeter long.
