252 DESCRIPTION OF SPECIES. 



of Lauras Reussii, Ell., "Bil. FL," ii, p. 5, pi. xxxi, figs. 5, 11. In this 

 European species, however, as seen at the base of fig. 11, the areolation is 

 much larger and the point of the leaves is obtuse. 

 Hab. — Corral Hollow, California. 



Laurus californica, sp. nov. 

 Plate LVII, Fig. 3; LVIII. Figs. 6-8. 



Leaves coriaceous, oval-oblong, tapering to an acute point, narrowed to the peti- 

 ole ; medial nerve narrow ; lateral nerves few, from 7 to 8 pairs, the lower pair at a 

 more acute angle of divergence, the upper open, sometimes nearly at right angles to the 

 midrib, unequal in distance and parallel only in the upper part ; nervilles anastomosing 

 or branching in the middle; ultimate areolation irregularly quadrate, large. 



The leaves of this kind are very numerous, and though apparently 

 differing in shape they all seem referable to the same species. The nerva- 

 tion in the upper part of the leaves is of the same character as that of fig. 1 ; 

 but it widely differs, especially by the more oblique basilar nerves. The 

 relation of these leaves to fossil species is with Laurus fOreoclaphneJ res- 

 urgens, Sap., "Et.," iii, i, p. 78, pi. vii, fig. 5, and to living species with 

 Phcebe triplinervis of Cuba. 



Hab— With the preceding.

 Ibid., p. 219, pi. xxxvii, figs. !-">, 7. 



This leaf is more rounded at base than any of those figured, I. c, 

 but except this there is not any difference. It is remarkably similar to 

 fig. 1 of pi. xxxvii, I. c, with the addition of a pair of marginal veins 

 about like those of fig. 7 of the same plate. 



Hab. — Corral Hollow, California. With the preceding. 



TILIACEJU. 



GREWIA, Juss. 



Grewia auric ulata, sp. nov. 



Plate LV, Fig. 1 



Leaves orbicular, auriculate at base, palmately nerved, obscurely crenate ; primary 

 nerves five, branching and curved upward ; secondary nerves camptodrome. 



The leaf is nearly exactly round, only a little narrower toward the base,
