(1999.) Q. cocci nea, Wang. Scarlet Oak. 



The limits of this tree are very uncertain, owing to the confusion 

 that exists in the minds of collectors, regarding it and Q. rubra. In 

 University Park, Toronto, are a few fine trees, but they become more 

 numerous to the west and in the forest along the Niagara Elver and 

 Lake Erie, it is an abundant tree. More investigation is necessary 

 before we can fix the exact limits of this species. (Macoun.) Vicinity 

 of Toronto. (A. Fowler.) 



(2000.) Q. tinctoria, Bartram. Yellow Oak. 



Q. discolor, Alton, Hort. Kew, III., 358. 

 Q. tinctoria, var. angulosa, Michx. Fl. II., 198. 



Q coccinea var. tinctoria, Gray, Man. 454, 1868. Macoun's Cat. No. 1609 

 in part. 



This species seems confined to western Ontario, as no specimens 

 have been seen from any point further east. It is not uncommon at 

 Niagara, and with the red and scarlet oak make up much of the forest 

 along Lake Erie and Niagara Eiver. {Macoim.) In\ woods; around 

 London, Ont. (Burgess.) 



(2001.) Q. palustris, Du Eoi. Pin Oak. 



Abundant in wet woods below Queenston Heights, and in all low 

 woods westward along Lake Erie and the Detroit Eiver to Windsor, 

 where it is of a very large size on the borders of the forest, and along 

 old fences. (Macoun.) Point Abino, Lake Erie. {David F. Day.) 

 Eoadside at Leamington, Essex Co., Ont. {Burgess.) 



555. CASTANEA, Ceertn. (CHESTNUT.)

C. vesca, Willd. Gray, Man. 455, 1868. Macoun's Cat. No. 1610. 



Plentiful in the vicinity of Toronto. (A. Fowler.) Common in the 

 valleys around Hamilton, Ont. (Logie.) Very common at Queenston 

 and Niagara Falls, and westward in the forest along Lake Erie and
