1 This plant is generally known under the name of Alum-root. In Arkansas, it grows especially on 

 dry rocky prairies. The whole plant is glandular, hairy, with roundish-lobed leaves from the root, like 

 the scape, bearing a long greenish raceme of small flowers. The pulverized root is used with success in 

 cancerous diseases. 



2 Resembles the true ITazel by its leaves, but easily known by greenish-yellow flowers appearing in the 

 fall and winter. Its branches were used for divining rods. The Indians used its bark as great medi- 

 cine. It has no real medical virtue. 



3 A large and beautiful tree, with compact, fine-grained, but easily decayed wood, used for cabinet- 

 work. The gum which exudes from the tree in summer has a pleasant odor, but no medical properties. 



4 Plants with various properties in different parts. Roots generally eatable and wholesome, like the 

 Carrot. Leaves and stems, as in the Water Hemlock, containing an acrid juice, often very poisonous. 

 Seeds with an aromatic oil, which renders them tonic, stimulating, and aromatic as medicines. The 

 name of the family indicates the disposition of their small white flowers borne on numerous pedicels 

 arranged like the branches of an umbrella. 



5 Plant with long linear leaves about one inch broad, ciliate with soft spines ; flowers on a long 

 peduncle, in round green heads. Root bitter, aromatic, highly esteemed in the South as diaphoretic and 

 expectorant. 



6 Sometimes escaped from garden.
