Carya bilinica Uug. 



After due reconsideration I admit these leaves as referable to Carya 

 bilinica Ung. The only difference, in considering the figures and descrip- 

 tions of authors, is that iu these leaves the secondaries which run high 

 aloug the borders appear to end iuto the small acute teeth, with a 

 branch passing under the teeth and continuing upward close to the 

 borders and along them. The leaves rather look like the form which 

 linger has figured iu Silloge, PI. xvin, as Carya Ungeri Ett. Same kind 

 of nervation is seen in Juglans cinerea, which has, however, the second- 

 aries less oblique.

Shasta County, Cal. Collected by Mr. J. S. Diller. Age, Mioceue. 

 Peisea Dilleri, u. sp. Plate xm, figs, 2-4. 



Leaves elliptical or oblong, gradually narrowed to a long petiole, ob- 

 tusely pointed, entire and subcoriaceous ; secondaries distant, parallel, 

 thin, curving in traversing the blade and along the borders, the upper 

 ones more curved. 



The leaves about 8 cm long, 3 cm broad at the middle, have 7 or 8 pairs 

 of secondaries at an angle of divergence of 40 degrees with a petiole 

 3 cm long, thick, eularged at the point of attachment. Toward the 

 apex of the leaves the secondaries are much curved, nearly in half 

 circle, separated by tertiaries or rather nervilles at right angles to the 

 medial nerve, forming by anastomoses very small quadrangular areola- 

 tion as iu species of Persea or Laurus. The lowest pair of veins are 

 slightly more oblique than the others, which are all nearly opposite. 



By the shape of the leaves, obtuse at apex, and by the areolation, 

 the species is related to Persea caroliniana, var. palustris Chapman, 

 from which it differs by the leaves being slightly shorter, the second- 

 aries at a more acute angle of divergence, and the petiole longer by 



1 cm
