Baeria maritima Lasthenia maritima is a species of flowering plant in the family Asteraceae known by the common names maritime goldfields and seaside goldfields.

[1] This species probably evolved from Lasthenia minor, and it is adapted to the unique conditions on these maritime islands: high winds, saline sea spray, and thin soils that are often disturbed by the activities of the seabirds that roost and nest on these rocks and made acidic and nitrogen-rich from their droppings.

[3] Lasthenia maritima is an annual herb with short, decumbent to prostrate stems lined with fleshy lobed or unlobed leaves up to 9 centimeters long.

The inflorescence bears flower heads lined with hairy phyllaries and ringed with 7 to 12 gold ray florets each about 3 millimeters long.

The fruit is a small, hairy achene often topped with a brownish pappus.
