LABRADOR BUTTERFLIES. 69 



much difficulty as far north as Caribou Island. Rhu- 

 barb is said to do well farther up the coast towards the 

 Mecatina Islands. Among the wild-flowers blooming 

 in the middle of July were the dandelion and Potentilla 

 anserina. Another Potentilla was the P. tridentata, 

 the mountain trident, with its three-toothed leaf and 

 modest white flower. It was pleasant to see this flower, 

 so familiar from my earliest childhood, as it flourishes 

 on the plains of Brunswick, Me., and is common on 

 Mt. Washington as well as on the mountains of Maine, 

 and abounds on the bare spots about Moosehead Lake, 

 particularly at the foot of Mt. Kineo. The wild cur- 

 rant, strawberry, and raspberry were in flower ; the straw- 

 berry plants were luxuriant, sometimes eight inches in 

 height, but the raspberries were dwarfed, not exceeding 

 the strawberry in height. Up the rivers the raspberries 

 and blackberries are abundant, but the latter low and 

 dwarfish. 



The shad bush (yAmelanchier canadensis) was now in 

 flower, blossoming in southern New England in April 

 or early May, while Rubus chamcemorus, the cloud-berry, 

 so abundant in Greenland and Arctic America as well as 

 on the fields of Norway and Sweden,. and the "tundras" 

 of Siberia, was going out of flower. With it were asso- 

 ciated the star-flower, Trientalis americana, a few Clin- 

 tonia borealis, Smilacina bifoliata and probably 61 stellata, 

 Streptopus amplexifolia ; one or two species of Andro- 

 meda ; an Iris, species of Vaccinium, \ht Arctostaphylus 

 uva-ursi or bear-berry ; the shore-pea, a honeysuckle 

 {Lonicera ccerulea), a Viburnum, and also the buckbean 

 {Menyanthes trifoliata).
