QUERCUS GROSSIDF.NTAI'A H. Sp. 



PL LXXXVn. ttg. 7. 



Leaf large, coriaceous, bmadly lanceolate (base destroyed), apex 

 acuminate; margin strongly toothed, the teeth sharp, upward pointing; 

 midril) perfectly straight; secondaries about 8 ov 9 jiairs, alternate, at 

 an angle of 45°, craspedodrome, slightly arching upward, ending in the 

 large teeth; nervilles strong, at right angles approximately to the midrib, 

 mainly percurrent, Ijut occasionally forked or broken, tiner ner\atiou not 

 retained. 



Unfortunately this tine species is represented In* the single specimen 

 figured, and this, it maybe seen, lacks the basal portion. The part retained 

 is 10 cm. long and 4.5 cm. wide. It was probably 14 or 15 cm. in length 

 when j)erfect. It has the margin strongly toothed, the teeth with long, 

 rounded or sharp points, each of which is entered by a secondarj-. 



Habitat: Fossil Forest Ridge, bed No. 5; collected by Ward and 

 Knowlton, August 19, 1887.

This is only a fragment of the base of a leaf It does not agree 

 absolutely with the figures of Lesquereux, but rather than make it a new 

 species I have referred it provisionally as above.
