60 Notes on some of the 



Quercus ambigua — Mx. Grey Oak. 



" Leaves sinuate acute. Bays acutish. Cups somewhat saucer-shaped. 

 Acorn turgid, eifg-shapcd." 



The grey oak of Michaud grows about Quebec in com- 

 pany with the red oak, which it closely resembles; so much 

 so that some writers will not allow them to be specifically 

 distinct. The timber is not in request. 



Quercus rubra — W. Red Oak. ChSne rouge. 



" Leaves long pelioled, oblong, glabrous, obtusely-sinuate. Lobes acutish, 

 toothed, ending by a bristle. Calyx saucer-forra, smoothish. Acorn

 however, can be said in favour of the timber ; being but 

 of indifferent quality ; it is only used for staves for sugar 

 hogsheads, and other dry casks ; large quantities of which 

 are annually exported to the West Indies, and rate

 same size. 



Quercus macrocarpa — Mx. Overcup Oak. 



" Leaves downy beneath, deeply lyrate-sinuate-lobed. Lobes obtuse, 

 repand, upper ones dilated. Calyx bonl-forni. Upper scales setose. 

 Acorn tnigid, ovate, large," 



A large tree producing timber of excellent quality. — 

 Pursh had a Canadian specimen of this tree ; but it does 

 not appear where he found it, — very probably in the upper 

 province. 



Quercus lyrata — W. White water Oak. 



" Leaves with very short petioles, smooth, lyrate-sinuate, widened at the top. 

 Lobes oblong, acute, upper ones trnncatc-angled. Cup depressed globular, 

 the scales ending in sliort firm points. Acorn globular, almost covered 

 by the cup." 



This oak grows ou the borders of the St. Lawrence in
