Flower-heads: growing singly on the ends of branched flower-stalks or scapes, and composed of strap-shaped flowers.

The prevailing idea that the leaves of the hawkweed resemble the rattlesnake, serve better to identify it from its numerous relatives, than which it is by far more interesting, than to recall to mind the dreadful creature for which it is named, or to remove the venom of his bite.
The plant grows in dry soil, sometimes by the waysides, in the meadows, or in the open woods.
H. Greenii, Green's hawkweed, has spatulate, tufted, basal leaves which narrow into a petiole. It is found in the dry soil of the mountains of Pennsylvania, Virginia and West Virginia.
