 Species. 1. Q. Phellos. (Willow Oak). 2. cineren, 

 (Grey Oak, Upland Willow Oak.) 3. pitmila, Mich. Q. 

 ssricea, Willd. Scarcely more than a swamp variety of 

 the preceding, but seldom more than a foot high, wliile 

 cinerea usually becomes a small tree. (Running Oak.) 



4. virens. The Live Oak, of slow growth like Q. JRobur 

 of Europe, produces ship-tiuj^er which is said to be 

 equally durable. It is occasionally cultivated in the mari- 

 time parts of South Carolina, producing the most magni- 

 £cent and important vistas- Through the avidity of a 

 temporary commerce it has been eradicated from exten- 

 sive districts, without the interposition of either private 

 or public caution for its renewal, although the soil in ma- 

 ny places is scarcely calculated for any other production. 



5. mantima. Obs. Shrubby, leaves semperviren*, often 

 sinuatfcly icothed, smooth, and of the same colour on both 

 sides. (Marine Oak.)

 A very doubtful species. 



1 1 Leaves toothed or shortly lobed. 

 9. agrifolia. Indigenous to the North West Coast of "

 this be an anomalous variety of coccinea? 11. hemispha-
