DESCRIPTION OP SPECIES. 53 



QUEBCUS SPUKIOILEX, sp. nov.' 

 PI. XLVIII, Fig. 3. 



Leaves small, coriaceous, oblong-, ovate-lanceolate, abruptly pointed, 

 truncate at base, dentate-spinose all around; midrib straight, rigid; sec- 

 ondaries open, more or less ramose or forking above, all the divisions enter- 

 ing the teeth, craspedodi-ome. 



The leaf is similar in its form, the dentation of the borders, and the 

 nervation to that of Q. ilex L., as represented by Scheuk in Zittel's liand- 

 buch der Paliioutologie," and it is also comparable t(i some of the forms of 

 the leaves of Q. chrijsopliiiHa Kellog-g and Q. nfirifoVia Nee, both living species 

 of California, and both species with leaves extremely variable in size and 

 fonn like Q. ilex. 



The leaf is aboiit 3.5™ long and 2""' broad, and has seven pairs of sec- 

 ondaries at an open angle of divergence of from ,50° to C0°; is dentate with 

 unequal, sharply acuminate or acute, open teeth, which are nearly 3""" long, 

 separated by obtuse sinuses. 



Habitat : Ten miles northeast of Delphos, Kansas. No. 4032 of the 

 collection of Mr. R. D. Lacoe. 



QuERcrs Wabdiana, sp. nov. 

 PI. VII, Fig. 1. 



Leaf large, coriaceous, polished on the surface, entire or undulate, even 

 obscurely distantly dentate, ovate-lanceolnte, obtuse, gradually narrowed 

 to the base; median nerve half round, comparatively narrow, of equal 

 thickness in its whole length, rigid ; lateral nerves alternate, close, nearly at 

 right angles towards the base, gradually more distant upward and at a broad 

 angle of divergence of 60°-70° above the middle, subcraspedodi-ome. 



This fine leaf is about 17"™ long (the apex being broken), obtuse, 8.5""" 

 broad in the upper part, gradually narrowed from below the middle to the 

 point of attachment, apparently a short petiole, which is broken. The upper 

 secondaries are at an equal distance, parallel, strong, but the lower ones, 

 six or seven pairs, are tliinner, less distant, gradually shorter and more 

 open, nearly at right angles. 



' This species was named Qitcrciis paeado-ilex, sp. uov., by Prof. Lesquereiix, but as this nauie is 

 antedated by the Qiierciis paeiido-ilex of Kovats (Fossile Flora v. Er<lob<?uye, 1856, p. 22, PI. ll, Fig. 6) 

 it becomes necessary to change it. I have called it Q. spiirio-ilej: with a view to still preserving its 

 implied relation to the living Q. ilex. — F. H. K.
