iPhone Closeups of Ridiculously small flowers

Really tiny flower...
Hard to even find one.

This little plant has been growing in the tortoise area. The tortoise has lots of cheeseweed to eat, but I'm worried that this little plant might be poisonous and that I'd better pull it out.

The problem is that I can't see the really really tiny flower in order to identify it!

So I've been playing around with my iPhone close-up to see if I can get a good picture.

This one is not bad.

I found this helpful article on shooting closeups with the iPhone and see that Camera+ is in my future.
