6. Q,. vi'rens, -^it. Leaves coria* 



ceoas, elliptic - oblong, somewliat 

 toothed or angled on Tonng trees, 

 entire on old ones, with a revolute 

 margin, rather acute at apex, but 

 not mncronate, steliately pubescent 

 beneath ; cupule turbinate, peduncu- 

 late ; acorn oblong. 



Geeen Queecus. Live Oak. 



stem 20 - 40 or 50 feet higli, and 1 or 2 - 5 or 

 6 feet in diameter, "vritli nimierons large "nide- 

 spreading crooked branches — the Vood re- 

 markahlT dense and heavy, with rsristed 

 gnarled fibres. Leaves an inch and a half to 

 3 inches long, perennial, bnt a portion of them 

 falhng from the old trees every spring, dart 

 green above, "whitish beneath, on short 

 petioles. Acorn ovoid-oblong or oval, of a 

 dark brown color, seated in a bowl-shaped 

 pednncnlate cup — ^the pedwide about an inch 

 long, axillary. 



Sea coast : Virginia to Florida. 



Ols. This noted tree — so valuable in ship-building — is pretty much 

 confined to the sandy sea-coast of the Southern States. Its most north- 

 em locality appears to be at Old Point Comfort, near Xorfolk, Virgi- 

 nia, — where it is reduced to quite a small tree. Four or five other 

 species, belonging to this group, are found in the United States — chiefly 

 in the South ; but they are mostly smaU, and of little value. 



Willow Oak Geoup. Leaves deciduous, entire, narrow. 



7. d. Phel'los, L. Leaves linear-lanceolate, tapering at each end, 

 glabrous ; cuj)ule saucer-shaped ; acorn roundish. 



Willow-leaved Oak. Willow Oak. 



Stem 40-60 or 70 feet high, and 1-2 feet or more in diameter, with a smoothish bark, 

 ieaues 2-4 inches long, subsessile, entire or the yonng ones sometimes dentate. Acorn 

 small, subglobose, seated in a shallow sancer-hke snbsessile cup. 



Moist low gromads. Xew .Jersey, Kentucky and South. 



Obs. There are apparently some varieties of this, — or, if they are 

 specifically distinct, nearly allied species. The tree sometimes acquires 

 considerable size, — but the timber is not particularly valuable ; and as 

 it is rather local in its habitat, is not much known beyond those Kmits. 



8. Q,. imbrica'ria, Mx. Leaves deciduous, lance-oblong or elliptic- 

 lanceolate, acute at each end, mucroiiate. smooth and shining above, 

 pubescent beneath ; cupule saucer-sbar, jj ; acorn somewhat hemis- 

 pherical.
