Erechtites hieracifolia /Composite Family
Pilewort is a member of the Composite Family. Although these may look like unopened buds, these flowers are in bloom. Each "flower" is made up of several small florets. The stamens and curled, Y-shaped pistils mature at different rates. Notice the small black wasp on the flowers at the lower left.
