Bur Marigold

I have a lot of yellow flowered plants, most of which I have been unable to identify even with the help of three guide books. I believe this is the Nodding Bur Marigold (Bidens cernua). It is a member of the Aster family. I found it growing in a swampy area next to the boardwalk.

For wildflower-watchers, yellow daisies are as numerous and difficult to identify as little brown birds are for bird-watchers. I have lots of photos of unidentified yellow daisies, and I know that some are in the genus Bidens, but I just can't figure out the species.

You could probably fill an entire wildflower guide with nothing but pictures of different species of yellow daisies!

Thanks this word of encouragement. I spent ages looking through books and on the internet and found tons of pictures of yellow flowers but only identified one of mine.

Every birder I know has a copy of Sibleys. What is the Sibley equivalent for Plant naturalists (and would it take a mule to carry it around?). Is there a "definitive" guide or a couple you could reccomend?

Unfortunately, I don't know of any. I just collect plant books because each will have something that none of the others do.
