Rattlesnake Weed.   H. venosum

Plate XLIII. Rattlesnake-Weed. - H. venosum

The loosely clustered yellow flower-heads of the rattlesnake-weed somewhat resemble small dandelions. They abound in the pine-woods and dry, waste places of early summer. The purple-veined leaves, whose curious markings give to the plant its common name, grow close to the ground and are supposed to be efficacious in rattlesnake bites. Here again crops out the old "doctrine of signatures," for undoubtedly this virtue has been attributed to the species solely on account of the fancied resemblance between its leaves and the markings of the rattlesnake.

H. scabrum is another common species, which may be distinguished from the rattlesnake-weed by its stout, leafy stem and un-veined leaves.
