correction, indeed, made by Dr Richardson himself, in a manuscript note be- 

 fore us. 



Houstonia ciliolata, Torrey. Banks of the Maitland River, Goderich, U. C. 



—II. longifolia, Willd. Banks of the Maitland River, Goderich, U. C H. 



patens, Ell. On mossy grounds in the elevated woods near Pittsburg Penn. 



BoRAGiNEiE. — Batschia Gmelini, Mich. On dry moorland ground, near 

 Brentford, Upper Canada. This is recorded by Pursh and other authors as 

 a native of the southern states. 



B. canescens, Mich — Dry sandy ground, St Clair Bay, Upper Canada. 



OrobanchejE — Orobanche Americana^ Linn. Woods at Denwiddy, St 

 Clair River, Upper Canada. 



Labiate. — Dracocephalum virginicum, W. Peninsula of Toronto, Upper 

 Canada. Bordering the swampy grounds on the Peninsula, this plant made 

 a very fine appearance, being covered with its bright purple flowers. This is 

 by no means, however, an abundant plant in Canada, as Niagara is the only 

 station quoted for it ; we were not fortunate enough to see it near the Falls, 

 neither on one side nor the other. Its principal habitats in the United States 

 are the mountain-meadows of Virginia and Carolina. 



Hyssopus nepetoides, Linn. Fertile places on the banks of the Thames Ri- 

 ver, New London, Upper Canada, 



Primulace^e Primula mistasinica, Mx. Moist places on the banks of the 



Maitland River, Goderich, in abundance. 



Chenopode^e — Chenopodium fruticosum, Linn. Salt marshes, Tuckerton, 

 New Jersey. This plant is described by the American authors as the C. ma- 

 ritimum, but it is undoubtedly the C. fruticosum of Linn. 



Euphorbiace^e — Euphorbia platyphylla, Linn. Umbellse 5-fidae, radiis 3- 

 fidis, bracteis cordatis foliisque lanceolatis serrulatis subtus pubescentibus 

 appendiculis involucri rotundatis, capsulis verruculosis glabriusculis. Spr. 

 Syst. Veg. — Hab. Banks of the river St Clair — This plant has not been be- 

 fore noticed as a native of America, although it is the most abundant plant 

 on the Canada side of the St Clair River for many miles. It always occupies 

 the poorest soil and bleakest situation. 



Euphorbia corollata, var. hirsuta. Banks of the St Clair River. This va- 

 riety is found mixed with the common plant, but by no means plentiful. It 

 is readily distinguished by its smaller umbel, and broader and more obtuse 

 hirsute leaves. 



Euphorbia polygonifolia, Linn. Dry sands on the banks of Lake Ontario 

 and Lake Huron. 



AmentacejE — Salix conifera, Waugh ; S. longirostris, Mx. Dry sandy 

 grounds, Peninsula of Toronto. 



This remarkable species of willow we saw in considerable quantity on the 

 peninsula at Toronto, forming bushes from 5 to 15 feet in height. The 

 branches are generally terminated by silvery, cone-like excrescences, which 

 are entirely the work of insects. The foliage being also of a silvery white, 

 gives to the tree a beautiful appearance. This willow has been mentioned by 

 Pursh and other authors, as indigenous only to the southern parts of the 

 United States ; but it may now be added to the Flora of Upper Canada. 



Orchide^e. — Triphora pendula, Nutt. On the banks of the Ohio River, 

 near Pittsburg. 



This curious plant was growing intermixed with Corallorhiza odontorhiza. 

 under the shade of Kalmia latifolia, at a considerable elevation above the river. 



Asphodele.^. — Aletris farinosa, Linn. We met with numerous habitats 

 for this plant in New Jersey and Pennsylvania. We also collected it at 

 Brentford in Upper Canada. 



Melanthace/e. — Zigadenus chloranthus, Rich. ; Melanthium glaucum, Nutt.
