52 SYLVAN ONTARIO. 



population farther south. It may be known by the greenish twigs, 

 the nearly smooth (not glaucous) leaves, with exceedingly fine bristle- 

 pointed teeth, and by the abundance of sweet berries covered with a 

 delicate blue bloom. A narrow-leaved form (var. angustifoliaGray) 

 is also found in northern Ontario. 



43c. Vfi.cclnium nlgrum (Britton). Low Black Huckleberry. 



Similar to the last but smaller, and bearing black fruit without a bloom. 

 By a curious compensation of Nature, however, the leaves are quite 

 glaucous beneath and often above. Very common in Muskoka and 

 probably found everywhere with the last species, but not , usually 

 recognized in our Floras. 



43d. Vaccinium Canadense (Kalm.). Canada Blueberry. 



This species is usually found in swamps, but although the fruit is abund- 

 ant and excellent it is less plentiful than the Blueberry of the hillsides. 

 The entire leaves and the twigs are thickly downy. 



43e. V actinium vacillans (Solander). Blue Huckleberry. 



Found in sandy soil in south-western Ontario. The twigs resemble 

 those of the common Blueberry, but the pale leaves are generally entire 

 and glaucous beneath, with netted veins and with the apex somewhat 

 mucronate. This species seems to be sometimes confused with V. 

 nigrnm above. 



43f. Vaccinium corymbdsum (L.). Swamp Blueberry. 



A tall shrub found usually in cold swamps. The leaves are larger than 

 in our common species, with margins entire and sometimes ciliate. 

 There are several varieties, often considered as distinct species. A 

 form with leaves very downy beneath and mucronate at the apex, with 

 black berries (var. atrococcnm Gray), is found in Ontario. 



43g. Vaeciniivm tiliyinosum (L.). Bleaberry. 



A form found only in the extreme north or on high mountains. The 

 smooth veiny leaves are nearly sessile, with a rounded appearance ; the 

 small berries resemble common species in the blue bloom and in taste. 

 Found also in Northern Europe and Asia. 



43h. Vaccinium Vitis-idcea (L.). Mountain Cranberry. 



A low creeper, resembling the Cranberries, but found in dry rocky 

 soil. Reported as common to Ontario except in the south, but I have 

 not been able to find it in Muskoka. The evergreen leaves are thick 

 and leathery with rounded apex and black dots beneath, and the fruit 

 is similar to that of the true Cranberries.
