heads--this is a discoid head (a head composed solely of disk flowers).  Do you see how the phyllaries appear white?  This is due to the thick layer of fine hairs that covers the phyllaries (it also covers the upper stem and leaves).   This is where the "woolly" in the common name "woolly ironweed" is derived. heads up close--can you find the corollas and stigmas in each disk flower?
