shining. Florets few, and of a bright purple. The leaves and flowers are 

 all upright, and, with the stem, hard and rigid. This interesting species 

 adorned the road-sides for several miles through the pine barrens to the east- 

 ward of Brentford, where we collected many flowering specimens during Au- 

 gust 1834. On showing this species to Dr Torrey of New York, he informed 

 me that he lately received specimens of it from Canada, and purposes calling 

 it Liatris cylindracea. 



Chrysopsis alba, Nutt. Dry hilly ground round the head of Burlington 

 Bay, Hamilton, Upper Canada — This plant was gathered in abundance at the 

 above station, amongst short grass, and in old burnt woods where the surface 

 was hard and dry. The plants were growing singly, two being seldom seen 

 within a foot of each other ; it is readily distinguished at first sight from all 

 other species of the genus by its lanceolate rigid leaves, and simple wiry 

 stem, which never exceeds 1 foot in height — This new addition to the Canada 

 Flora has hitherto been only noticed as inhabiting the banks of the Missouri 

 river near Fort Mandan. 



Cacalia tuberosa, Nutt. Banks of the Maitland river, Goderich, U. C. 

 In shady situations, bordering on the Maitland river, this plant was seen in 

 great abundance. Those first observed by us, not being in flower, were 

 passed for a species of Plantago, whose leaves it very much resembles. Pro- 

 ceeding farther up the river we met with the plant in greater quantities, and 

 in full flower. The only stations known for this plant previous to our find- 

 ing it in Canada were on the banks of the Missisippi, about Natchez, and 

 near St Louis. Nutt. Gen. Plant. 



Rudbeckia hirta, Linn. Dry sandy banks, Peninsula of Toronto. This 

 plant is mentioned by Pursh as a native of the mountains of Virginia and 

 Carolina. It presented quite an alpine appearance, varying from 2 to 12 

 inches in height, and densely coated with rough hairs. 



Campanulace^e — Campanula linifotia, Hsenk. — Caule sub-3-floro, foliis lan- 

 ceolato-linearibus subintegerrimis subsecundis, summis angustissimis, floribus 

 cernuis. Spr. Syst. Veg — Hab. Dry barren places, St Clair Bay, Upper Ca- 

 nada. Besides this station, this plant was also seen, though sparingly, on 

 the Peninsula at Toronto. Its dark blue drooping flowers render it an 

 interesting object in such wildernesses. 



Lobeliace.<e. — Lobelia cardinalis, alba. Swampy places, Goderich Road, U. 

 C. The common scarlet kind covers large tracts of moist places in many parts 

 of the country ; but in no district did we witness it in such perfection as on 

 the marshy grounds leading from new London to Goderich. Out of such 

 quantities it was really surprising to see so few varieties. A small number 

 were observed of a delicate white, and some intermediate between that and 

 scarlet, but the white variety was by no means plentiful. 



Erice^e — Arbutus Uva-Ursi. This plant was seen in great abundance on 

 dry barren situations in the neighbourhood of the great lakes, as also on the 

 pine barrens of New Jersey. But, like the Linnaea borealis, Azalea procum- 

 bens, &c. &c. it differs from the British type in having much larger leaves 

 and fruit, and being of more upright growth. 



PYROLACEiE. — Pterospora Andromedea, Nutt. In beech woods, west of 

 Kingston, Upper Canada. 



Gentians — Gentiana alba, Muhl. Cat. ; caule simplici tereti glabro, foliis 

 ovatis acuminatis amplexicaulibus trinerviis, floribus terminalibus sessilibus, 

 laciniis calycinis late-ovatis acuminatis reflexis, corolla ventricosa 5-fida, laci- 

 niis internis parvis denticulatis Hab. Dry stony places, Allegheny Moun- 

 tains. Two beautiful specimens in the Muhlenberg Herbarium, now in the 

 possession of the Lyceum of the Natural History Society at Philadelphia, are 

 identical with those found by us on the Allegheny Mountains on the 15th 

 of September 1834 ; but whence they came is unknown. At this time 

 the plant was in full flower; it was growing in robust tufts, with stems 1 foot 

 high, having opposite amplexicaul leaves, and crowned with a large head 

 of white bell-shaped flowers — While looking through the species of Geniiana^
