dwarf phase of the above, when growing on barren rocky 

 ground, resembling in every respect the preceding. Stem not 

 more than six inches high. Annual. 



Erigeron Bonariencis. L/inn. (fleabane. ) An erect leafy 

 plant, hairy, stem one to three feet high, branched above. 

 I/eaves lanceolate, one-third to half-inch wide, the lower ones 

 toothed. Flower-heads small; flowers white, one-third of an 

 inch broad. Common everywhere. May to August. Annual. 



Erigeron Annuus. Ivinn. An erect, stout stem, three to four 

 feet high, leafy from the base, branched, hairy. Ivcaves four 

 to six inches long, one and a half-inch wide, slightly hairy, 

 ovate, coarsely toothed in the middle Flower-heads large and 

 scattered. Flowers half inch in diameter, white, tinged with 

 purple. April to July. Annual. 



Erigeron Jamaicensis. Ivinn. It is yet an open question 

 whether this species is an Erigeron or an Aster I am inclined 

 to the latter belief. It is a plant with slender stem, six to 

 eighteen inches high, according to locality, nodding before the 

 flowers expand. The root-leaves roseate, blunt; stem leaves 

 few, distant, clasping the stem, one to one and a half inch long. 

 Heads few; flowers half inch in diameter, with numerous pur- 

 ple rays and yellow disk. April and May. Annual. 



In addition to the foregoing. I^efroy enumerates E. liniflorus, 

 B. philadelphicus, and E. quercifolius, but without any des- 

 cription. 



Artemisia Termifolia. Willd. (french fennel.) A tall 

 plant, four to six feet high. lycaves divided into numerous 

 slender filaments. Heads small and numerous; flowers whitish 

 yellow. August and September. The white plant has a fetid 

 smell. Annual. 



Senecia Vulgaris. Ivinn. (groundsel.) An erect weed 

 with fleshy stem, up to a foot high. Leaves divided half way 

 from margin to midrib, toothed. Flower-heads few, drooping. 

 Waste places, but not as abundant as its feathery seeds would 

 indicate as likely. Flowers one-third of an inch in diameter, 

 Yellow. April to July. Annual.
