Variegated Milk-weed. 
This beautiful species is easily recognised by its white and 
red flowers. From eighteen inches to two feet high. On the 
borders of woods and in open woods. Jersey, frequent. Not 
so often met with on the Pennsylvania side of the Delaware. 
Perennial. July.

undulate ; umbel terminal on a long peduncle,

A. purpurascens, Walt. 
A species easily distinguished from its congeners, by the 
very long terminal peduncle, and blunt or rounded amplexi- 
caule leaves, waved on the margin. Flowers large, purple. In 
sandy fields of Jersey, and in dry sandy woods, tolerably fre- 
quent, particularly a few miles south of Camden. Perennial.

petiolated ; in the middle of the stem the large 
ones in fours ; umbels two, terminal, loose-flower- 
ed, pedicels filiform.^ — Jacq.

This very pretty species is readily distinguishable from all 
the others by its linear leaves. From fourteen inches to two 
feet high ; flowers NapLes-yellow and white. Very rare; I have 
only found it sparingly in a hedge, close to the spot already 
particularised as the habitat of Iris prismatica. Perennial. 
June, July. 
10. A. stem somewhat upright, divaricate-branch- 
ing, very hirsute, leaves scattered (crowded and 
alternate) oblong-lanceolate, hirsute, umbels
