the comparatively narrower, though prominent medial nerve and the 

 slender petiole. In fig. 1 of pi. xcvii Heer has figured a smaller leaf with 

 narrower midrib, and other authors have leaves of this species with still 

 narrower midribs than in specimens which I have figured. 

 Hah. — Corral Hollow, California. 



Liaurus grrandis, sp. nov. 

 Plate LVUI, Figs. 1, 3. 



Leaves coriaceous, large, ovate or obovate, gradually narrowed to the base, 

 rounded in narrowing upward to the point (not seen); pinnately nerved; lower second- 

 ary nerves thin, at right angles, gradually more curved and more oblique upward 

 in traversing the blade, flesuous, branching and anastomosing in arches toward and 

 along the borders, distinct; areolation very small, punctiforni. 



These leaves are numerous but fragmentary, none of them with the 

 apex preserved. The largest, which is the one figured, is about 18 centi- 

 meters long, 7 to 8 centimeters broad in the upper part, where it is the 

 widest. The medial nerve is rather thin, as in the leaf described iibove; 

 the lower secondary nerves are thin, at right angles, like tertiary ones, ail 

 undulate, the upper gradually more oblique, distant; nervihes strong, 

 branching or anastomosing at right angles in the middle. The areolation 

 is seen in fig. 3. 



The leaves have some relationship to those I have described as L. 

 princeps and are mixed together. The difference in the form, the size of 

 the leaves, and the nervation authorize specific separation. 



Hah. — Same as the preceding. 



Laurus salicifolia, sp. nov. 

 Plate LVIII, Figs. 4, 5. 



Leaves coriaceous, lanceolate or linear-lanceolate, equally narrowed upward to an 

 acute point nnd downward to the petiole; lateral nerves numerous, open, parallel, 

 camptodrome; areolation puuctiform. 



The leaves, of which there are a number of specimens, vary in size 

 from 6 to 11 centimeters long, 1* to 2-J centimeters broad. The medial 

 nerve is not thick. Except one pair of basilar nerves, which follow the 

 borders and are at an acute angle of divergence, all the others are open, 

 unequal in distance, more or less parallel, remarkably similar in their 

 characters to those of fig. 8. These leaves are mixed together and are, 

 perhaps, referable to the same species. They may be compared to those
