stems lack the wings that are conspicuous in Verbesina virginica. notice also the new leaves developing  from axillary buds

yellow heads - can you identify the two types of flower within the inflorescence? the large outer ray flowers are zygomorphic  with three lobes apically (at the ends). the disk flowers in the center are actinomorphic.

the 5 corolla lobes present in each of the disc flowers can be clearly seen Can you see the androecium and gynoecium of the individual disc flowers? The anthers are fused to form a tube that is slightly red in this species. The style lobes can be seen exerted from this tube in the outer disk flowers.
