Erigeron bellidifolius, Muhl. (Robin's Plahtaix.) 



Open ground. Not rare. 

 Erigeron PhiladelpMcua, L. (Cojimox Fleabaxk.) 



Essex county (memo. G. D. Phippen) ; Danvers, 1853 (Dr. Osgood's 



list). Ko authentic specimens of this species have been seen, and 



it is doubtful as an Essex county plant. 

 Erigeron annuus, Pers. (Daisy Fleabanb.) 



Fields and roadsides. Common. 

 Erigeron strigosus, Muhl. 



In similar situations to the last. Common. 



Solidago squarrosa, Muhl. 

 In a letter to Dr. Chas. Pickering, Feb. 20,1828, Wm. Oakes, speaking 

 of what he had found new while botanizing, says, " I found a fine 

 spot of S. squarrosa iu your locality;" which Dr. Pickering said 

 must hare been Esses Co. The only specimens yet collected are 

 from Beverly, 1879 (J. H. Sears). This species is more common in 

 the mountain regions of JIaine, New Hampshire and Pennsylvania. 



Solidago bicolor, L. (Pale Goldbjs-rod.) 

 Dry places. Common. 



Solidago latifolia, L. 

 Georgetown, Boxford, Amesbury, etc. Not very common. 



Solidago csesia, L. 

 Moist woods. Frequent. 



Solidago puberiila, Xutt. 



Common near the coast, less so in the interior towns. 



Solidago stricta, Ait. 

 AVenham swamp, 1824 (Dr. Chas. Pickering) ; "Bowler swamp and 

 similar localities in Lynn" (Tracy). Not in the P. A. S. county 

 herbarium. It is very possible there is some mistake and that this 

 species does not grow here, as no specimens have since been found 

 and forms of S. neglecta are sometimes mistaken for it. 



Solidago speeiosa, Xutt. 

 Ipswich (Oakes) ; Georgetown (Mrs. Horner) ; Danvers (J. H. 

 Sears). Not uncommon. 



Solidago sempervirens, L. (Seaside Goldex-rod.) 

 A very handsome species along the ocean shore. Common. 



Solidago elliptiea, Ait. 

 This species probably comes within our county flora as it has been 

 found south of the county line. A species found at Point Shirley 

 (C. E. Faxon), supposed to be this, now proves to be a hybrid be- 

 tween S. sempervirens and some other species. 



Solidago neglecta, Tan- & G-ray. 



Swamps. Common. A large form grows at Essex with very ex- 

 extensive panicles of flowers.
