through another thoroughfare than that of Lake Champlain, namely 
by the St. Francis River of N. Maine. 
Juncus Vaseyi, Engelm., and Nabalus racemosus, Hook., extend as 
far east as the shores of the St. John’s of N. Maine; and there, also, 
were found Primula Mistassinica, Michx., Anemone multifida, DC., 
Vaccinium caespitosum, Michx., and Allium Schoenoprasum, L. 
As Erigeron acre, L., was seen not many miles north of Maine, it 
is very probable that it grows within its borders. 
On the south shore of the St. Lawrence, about one hundred 
miles below Quebec, I found myself last August surrounded by a 
flora almost subarctic in character. Stunted growths of Abies alba, 
Michx., A. nigra, Poir, and A. balsamea, Marsh., constituted almost 
the entire arboreal vegetation seen along the shore. Growing from 
the crevices of rocks, usually within reach of the salt waves, Plantago 
maritima, L., a plant which Gray’s Flora locates north of the Gulf of 
St. Lawrence, was abundant. Higher up, Empetrum nigrum, L., 
and Vaccinium Vitis-Idaea, L., carpeted the scanty soil, and with 
these mingled Draba incana, L., D. arabisans, Michx., Zygadenus 
glaucus, Nutt., Potentilla Pennsylvanica L., Cerastium arvense, L., 
Archangelica Gmelini, DC., Conioselinum Canadense, T. & G., Gen- 
tiana Amarella, L., var. acuta, Hook. f., Halenia deflexa, Griseb., etc. 
On the beaches, among the more common plants of the sea- 
side, Mertensia maritima, Don, trailed profusely its glaucous fillets 
spangled with blue flowers, and Poa glumaris, Trin., a species of 
Siberia and Alaska, had spread abundantly by means of its thick 
subterranean stems. Elymus mollis was common with the latter. 
In the marshes Nabalus racemosus, Hook., was common, (as, also, 
in higher situations,) Aster angustus, T. & G., was seen; Cata- 
brosa aquatica, Beauv., was not rare; and common with Carex mar- 
itima, Vahl., and C. salina, Wahl., were C. Norvegica, Schk., C. 
limula, Fries, and C. helvola, Blytt? The purple plumes of Hor- 
deum jubatum, L., were waving everywhere. In places where the 
grasses and sedges were sparse, the slimy surface of the marsh was 
covered with Stellaria humifusa, Rottball.; and, where a rill spread 
over the border of a marsh, I came upon a large patch of Pedicu- 
laris palustris. L., var. Wlassoviana, Bunge, a plant hitherto supposed 
to grow no nearer than Hudson’s Bay. In low wet places among 
the rocks with Juncus Balticus, Dethard, Glaux maritima, L., etc., 
Pleurogyne rotata, Griseb., and Blysmus rufus, Link., were de- 
tected. In the fields near the shore, the herbage upon which the 
cows were feeding was chiefly composed of Poa pratensis, L., indi- 
genous form, Festuca ovina, L., supposed also to be native, Vicia 
cracca, L., Carex atrata, L., Poa caesia, Smith, Euphrasia officinalis, 
L., a form four to six inches high and much branched, doubtless 
introduced from Europe like the two following, Rhinanthus Crista- 
galli, L., Silene inflata, Smith, Primula farinosa, L., Potentilla Penn- 
sylvanica, I., P. tridentata, Ait., and Gentiana Amarella, L., var. 
acuta, Hook, f. iG. G. PRINGLE.
