Requesting to please ID this plant with yellow flowers captured on a beach in San Francisco, USA in May 2013.

A close look at the pictures gives me a clue – white tipped ray-florets in one or two heads! And linear leaves! Flowering season May.
Your plant may be Eriophyllum lanatum (Pursh) Forbes. Please check –

Thank you,

Thank you … for this detailed analysis…I had not noticed the white tips, it is very interesting.
On going through the links provided by you, I think that the ray florets of the Eriphyllum lanatum are longer than those in the attached pics.
I would lie to know your opinion of the same…

If you allow me to express my concern freely, i am more troubled with distal opposite leaves.
Instant check gave me the species i suggested. Please wait for more inputs. Other members may come up with more precise id.
