This yellow Asteraceae flower is a composite flower (capitulum)consisting of multiple individual flowers attached to the same base. In this picture both the flowers on the outside of the composite flower (the ray florets) are open as well as the inner flowers (the disk florets). The ray florets fuse their petals into one giant lobe (which may people confuse with the petals of a single flower), and the inner flowers fuse their petals into a tube.

This yellow Asteraceae flower is a composite flower (capitulum)consisting of multiple individual flowers attached to the same base. In this picture both the flowers on the outside of the composite flower (the ray florets) are open as well as the inner flowers (the disk florets). The ray florets fuse their petals into one giant lobe (which may people confuse with the petals of a single flower), and the inner flowers fuse their petals into a tube. See the previous picture for the same plant's flower before the disk florets are open. This is most likely one of the several species of tarplant, possibly _Deinandra_.
