Male and female stroboli "flowers" are very small, you can see the remnants of the males in the picture above, and the female below.
Misidentification: Look for the smaller woody cones and the lower side of the branchlets having the distinct white X's. Not exclusive of this species but the small cones and the flatted sprays will help.
Locations: To be honest they are not that common, several at Cabrillo College on the "lower campus",
A nice one on the corner of Chestnut and Center in SC.
