1869. J MATTHEW — ON PLANTS IN ACADIA. 145 



Heather, {Calluna vulgaris,) has been found near Halifax, by 

 Prof. Lawson, and is more abundant at Cape Breton and New- 

 foundland. It is accredited to New Brunswick, by Loudon. 

 Prof. Bailey noticed the Bog Bilberry (^Vaccinium uliginosvm,') 

 and the Cow Berry (Vaccinium Vitis Idea,) growing on Bald 

 Mountain, the culminating point of the Northern Highlands, but 

 does not seem to have met with any other representatives of this 

 type at the north. We may, perhaps, except the mountain 

 Cinquefoil {Potentilla tridentata,) gathered on the Tobique River, 

 but which, although commonly considered Sub- Alpine, has such 

 a range in Acadia, as to show that it may perhaps, with more 

 propriety, be looked upon as a Boreal form. These, and the 

 remaining species of the hst, not noticed above, find a congenial 

 climate at St. John. One very obvious cause of their presence 

 here, as already observed, with regard to other species, is the 

 abundance of cool sea fogs in summer time, and consequent low 

 temperature and moist atmosphere. The more thoroughly 

 Arctic species, such as the Cloud Berry (Ruhus Chamcemorus) 

 and the Crow Berry, (^Empetrum nigrum,) show a partiality for 

 the peat bogs, so common in our " Barrens," where they grow in 

 company with the Bastard Toad Flax, (^Comandra livida,) and 

 other high northern forms. 



The Sub- Arctic species of our list, have been mostly gathered 

 on the cliflFs and terrace banks, bordering the Bay of Fundy. On 

 these, the Eyebright, (^Eiiplvrasi i officinalis,) and the Thyrsoid 

 Goldenrod [Solidago thyrsoidea) abound. The first of these 

 has also been met with at Dalhousie, on the Bay of Chaleur. 

 The mountain Cinquefoil has an extensive range throughout 

 Acadia, having been seen near Mount Katahdin, on the Lower 

 Tobique, at several points around the Bay of Fundy, and on the 

 coast of Maine. It even flourishes at Windsor, Nova Scotia, 

 where the mean summer temperature cannot be far from 65° 

 Fahr. The Green Spleen wort, (A.^plenium viride,) a native of 

 Newfoundland, Gaspe, Labrador and the Rocky Mountains, 

 grows on the sea cliffs near this city, in company with Carex 

 canescens var. vitilis, Cinna arundinncea var. pendula, &c. I 

 may add that the Cowberry, ( Vaccinium Vitis Idea,) which goes 

 by the name of Hill Cranberry with us, is not only quite common 

 near the coast of the Bay of Fundy, but has also been met with 

 by Mr. Fowler, at Richibucto.
