Rattlesnake Weed
Hieracium venosum
from the link ☼
The purple veined-leaves of rattlesnake weed are unmistakable. Yellow flowers bloom on a long, wiry stem (making it hard to get both flowers and leaves in focus in a photograph).
Botanical Source.—This plant has a perennial root, with a stem or scape from 1 to 2 feet in height, dark-brown, slender, sometimes naked, sometimes with 1 or more glabrous, cauline leaves, forking above several times into a spreading, loose corymb, with an awl-shaped bract at each division. The radical leaves are obovate or oblong, somewhat acute, nearly entire, subsessile, thin and pale, purplish, and glaucous underneath, a little hairy above, often hairy along the midrib, marked with purple veins, and the first that unfold are close to the ground.
