Cobweb Thistle
(Cirsium occidentale var. californicum)  
Composite / Sunflower (Asteraceae) family
Perennial
Bloom times: approx. April - June

It's easy to see why cobweb is in the name.
Filmy threads are wound over the area below (floral bracts) the thistle flowers. There are only a few of these on and around the dunes. They range in height from a foot to 2 feet tall.
