Bearded Clover (Trifolium barbigerum), Bodega Head, 19 April 2017

P.S.  Check out the interesting color patterns on this clover's leaflets (on the left-hand side of the photo).  I'm intrigued by the markings, so I did a quick search into what's known about the patterning.  It sounds like they're formally called "anthocyanin leaf markings" and they're known to be linked to certain genes.

Close-up of Cow Clover (Trifolium wormskioldii) 

These clovers were photographed along Westshore Road between Owl Canyon and Campbell Cove on 31 May 2013 .  Here are two more views of this striking, large, native clover (sometimes called the Coast Clover or Springbank Clover).

 

 

According to Wikipedia, this species was named after a Danish botanist, Morten Wormskjold.  He participated in an 1815 Russian expedition aboard the Rurik commanded by Otto von Kotzebue.  Other famous naturalists on this expedition included Adelbert von Chamisso and Johann Friedrich von Eschscholtz.
