spear saltbush (atriplex patula, subspecies hastata) found by Gustafson and Brandman
Henrickson calls it non-native
This annual plant has, broadly triangular leaves. It has small greenish flowers without petals that blooms June to November. The arrow-shaped leaves help identify this salt-tolerant plant. It is common along the San Francisco Bay’s edge. It sheds salt through it's leaves and the crystals can be seen on the underside of the leaves. Because these plants are in a fresh water environment, you will not find any salt on the underside.
