Help Identifying Several Orange County Plants

Searching several plant lists on the internet yielded no results for these. Here's hoping someone here can help me identify these.

Taken at Casper's Wilderness Park





Aliso Canyon



Bolsa Chica

 

First is an aster or relation
Second is a hawthorn

Try some guidebooks to the wild plants of the region if you are falling short using the internet.

 

Corethrogyne filaginifolia, cudweed-aster
Ambrosia psilostachya, ragweed
possibly Rumex crispus?, curly dock
Mesembryanthemum crystalinum,? ice plant

 

Now I see the inflorescence of the ragweed.

 

Wow, thanks for the responses! Also, that could very well be Curly Dock - I saw several specimens of it around Aliso Canyon. I guess I didn't recognize it because of the more reddish coloring?

 

Also from Casper's Wilderness Park

 

Brickellia californica
possibly Heterotheca grandiflora
Salvia mellifera?

 

Thanks. I'm almost certain that isnt Heterotheca grandifolia though - it lacks the branching stems.

 

Here's another one:
