OKDEE CXII. MYRICACEJE BAYBEKRY-TRIBE. 



shallow, saucer- shaped, much shorter than the oblong-ovate acorn. A tall 

 handsome tree, very common in forests every where. The wood is reddish an< 

 coarse-grained, chiefly valuable for fuel. The leaves turn red in autumn. May 



6. Q. coccinea. Scarlet Oak.

 bright-green on both sides, on long petioles ; lobes divaricate, sparingly toothed 

 with broad, open, deep sinuses, which extend two-thirds to the mid-vein, or 

 further ; cups very scaly, somewhat turbinate, inclosing about J of the round 

 ovate, acorn. A very large and handsome tree, of symmetrical growth, dis 

 tinguished from the last especially by the smaller, bright-green leaves, which 

 are much more deeply lobed, and turn crimson in autumn. May.

 Quercitron of dyers. The leaves turn to a brownish-yellow in autumn. May.

Young branches glandular-pubescent leaves cordate, rounded, acuminate, 



coarsely serrate ; aments appearing before the leaves ; stigmas of the fertiU
