 northern and peninsular Florida, except the extreme southern portion. The brown 

 or reddish-brown heart-wood is coarse-grained, heavy, hard, and strong. (Cont.) 



13. Q. Phellos L. Tree becoming 25 m. tall: leaves sometimes persistent; 

 blades linear-oblong or narrowly elliptic to lanceolate or oblanceolate, 4-10 

 cm. long, shining and glabrous at maturity, entire: acorn sessile or nearly so; 

 cup saucer-shaped, 10-15 mm. wide; nut subglobose, often depressed or globose- 

 ovoid, about 1 cm. long. 



The WiLLOW-OAK grows in swamps, and on margins of streams in northern
