WEEDS AND USEFUL PLANTS. 



205 



6. ft. vi'rens, Ait. Leaves coria- 

 ceous, elliptic - oblong, somewhat 

 toothed or angled on young trees, 

 entire on old ones, with a revolute 

 margin, rather acute at apex, but 

 not mucronate, stellately pubescent 

 beneath ; cupule turbinate, peduncu- 

 late ; acorn oblong. 

 GREEN QUERCUS. Live Oak. 



Stem 20-40 or 50 feet high, and 1 or 2 - 5 or 

 6 feet in diameter, with numerous large wide- 

 spreading crooked branches the wood re- 

 markably dense and heavy, with twisted 

 fnarled fibres. Leaves an inch and a half to 

 inches long, perennial, but a portion of them 

 falling from the old trees every spring, dark 

 green above, whitish beneath, on short 

 petioles. Acorn ovoid-oblong or oval, of a 

 dark brown color, seated in a bowl-shaped 

 pedunculate cup the peduncle about an inch 

 long, axillary. 



Sea coast : Virginia to Florida. 



Obs. This noted tree so valuable in ship-buildingis pretty much 

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

 ern locality appears to be at Old Point Comfort, near Norfolk, 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 small, and of little value. 



** WILLOW OAK GROUP. Leaves deciduous, entire, narrow. 



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

 glabrous ; cupule 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. 

 Leaves 2-4 inches long, subsessile, entire or the young ones sometimes dentate. Acorn 

 small, subglobose, seated in a shallow saucer-like subsessile cup. 



Moist low grounds. New Jersey, Kentucky and South. 



06s. 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 limits. 



8. ft. imbrica'ria, MX. Leaves deciduous, lance-oblong or elliptic- 

 lanceolate, acute at each end, mucronate, smooth and shining above, 

 pubescent beneath ; cupule saucer-shaped ; acorn somewhat hemis- 

 pherical.
