 tic, oblong or oval, the teeth appressed, the apex 

 and base mostly acute; petioles 2"-3" long; stip-

 50°, with trunk diameter of 32°, but usually 

 smaller. Leaves ovate or ovate-lanceolate, vari- 

 ously dentate, abruptly acute or acuminate at the 

 apex, rounded at the base, glabrous on both sides, 

 very resinous when young; flowers white, 8"-l2"
