46 SYLVAN ONTARIO. 



29b. Crataegus macrnctintha (Ladd.). Long-spined Thorn. 



Common in Muskoka and eastern Ontario, but very variable in leaves 

 and thorns. The flowers are about a week later than in C. cocci)iea 

 and C. rotund (folia and, like the former, bear j>in& anthers, while those 

 of the latter are white. 



29c. Cratiicyua rotundtfolia (Borck.). Round-leaved Hawthorn. 



A common form in Muskoka, marked by shorter thorns and leaves 

 nearly as in the last but less deeply cut. Specimens which have been 

 cropped by cattle often develop very many long and stout thorns. 



29d. Crntacijus in6tt (Scheele). Red-fruited Thorn. 



Differs from C. coccmea mainly in its larger leaves, which are very downy 

 beneath. It is apparently not common, though distributed over the 

 Province. 



29e. Grahtegus tomentosa (L.). Pear Thorn. 



Very downy on twigs, petioles and lower surfaces of leaves. The leaf- 

 bases are, however, unlike the last in being acute or wedge-shaped and 

 the petioles more or less winged. It seems to be confined to our 

 southern border. 



29f. CrofatV/.c Crus-GkUli (L.). Cockspur Thorn. 



This species and the next differ from the preceding forms in the leaves, 

 which are merely serrate or 2-serrate, and not cut-lobed. The thorns 

 are very numerous, long and slender, sometimes reaching four inches. 

 Common in the Niagara and Erie districts. 



29g. Cratahjiiit pnnctata (Jacq.). Large-fruited Thorn. 



Resembling the last, but with shorter thorns that are often branched. 

 The small leaves also are more downy beneath and very finely serrate. 

 Found along our southern border from the St. Lawrence to the St. 

 Clair. 



30a. Amdrim'hiiT Canndensis (T. fc G.). Canadian Juneberry. Shad-bush. 



May-cherry. Bill-berry. 



The largest of the Juneberries, and becoming a tree even in the north. 

 All of our species have a peculiar dull bloom on the upper surfaces of 

 the leaves, which, with the round glandless petioles, distinguishes them 

 from their cousins, the Cherries. The bark has the peculiar "cherry " 

 taste, while the fruit shows a close relationship to the Apples. This 

 species is usually found in dry woods and has its leaves nearly smooth 

 when fully grown. 



30b. Amelanchier Botryapium (D. C.) Swamp Juneberry. Bill-berry. 



Smaller than the last, and preferring moist woods. The leaves are $ery 

 downy, especially when young. Common in Muskoka, and appearing 

 in at least two varieties.
