478 BOTANY OP LAKE HURON, 



(S. officinale), and the Euphorbia cerollata, all plants of soutlierR 

 origin, and elsewhere in Ontario but locally distributed — the range 

 in almost every instance being south of their present locations. The 

 Golden Club (Orontmm Aquaticum), an aquatic perennial with a 

 deep root-stockj and strongly-nerved floating leaves, was detected in 

 a pond near the embouchure of the Bayfield River. This station is 

 certainly wonderfully inland for a plant usually found delighting in 

 ponds near the sea coast and in river marshes of the tide- water, being 

 in its present habitat nearly 700 miles from the sea. Heretofore 

 its more northern station has been a point about 400 miles up the 

 valley of the Susquehanna, at Gilbertsville, in the County of Otzego, 

 (Paine). On the wooded hillsides of the Aux Sables and Lake Bur- 

 well occurs the Chestnut (Gastanea vesca), with its aments as long as 

 its leaves, and so numerous as to impart a yellowish hue to the whole 

 tree when in blossom. Equally remarkable for its long pendulous 

 aments of barren flowers hanging from the ends of its branches, 

 though in other respects so dissimilar, is the shrubby Hazelnut 

 (Corylus Americana), v>^hich m the barren plams of Bosanquet is 

 found in great abundance, associated with the Eed Pine, the Staghorn 

 Sumach, and the Black Scrub Oak. The following species comprise 

 the more important additional representatives of this di-^dsion : — 



Thalictrum anemonoides. Aster laevis, var. cyanei;s. 



Hypericum kahnianum. Artemisia biemiis. 



Enonymus atropurpureus. Lobelia spicata. 



E. Americana. Monarda didyma. 



Vitis riparia. Physalis viscosa. 



Lupinus perennis. Prosartes lanuginosa, 



Erigenia bulbosa. .Juncus acuminatus. 



Gerardia integrifolia. Pauicnm virgatiim,
