DESCRIPTION OF SPECIES. 93 



gradually narrowed to the petiole but somewhat rounded in narrowiug 

 to it. Its precise relation is not satisfactonly ascertained. 



It is, indeed, comparable by its form to some varieties of L. primigcnia 

 Ung., and especially to L. Beussii Ett. (Flora v. Bilin, pt. 2, p. 5, PI. xxxi, 

 Figs. 5 and 11), having also, by its numerous intei-mediate tertiaries, a 

 marked relation to species of Salix and even to Dewalqnca haldemiana Sap. 

 &. Mar. (Marnes. Ileers. de Gelinden, PI. vu. Figs. 1, 2). I consider it, 

 however, as referable to a species of Laurus, comprising in its characters 

 those of some varieties of L. primigcnm Ung., resembling especially the 

 figure of this species in Saporta, Etudes, vol. 2, PI. vii. Fig. 7.

Leaves linear-lanceolate, tapering to the acuminate apex, entire; pri- 

 mary nerves naiTOw, secondaries arcuate, camptodrome. . 



Heer remarks on the leaves of this species that they are mucli like 

 those of L. plutonia, differing by the smaller size, the nearly linear form, 

 being narrower and more acute at the apex. The fragment which I refer 

 to this species is of exactly the same size and form as that in Heer's PI. 

 XLIII, Fig. Ic. It is indeed part of a leaf quite as large as those Avhich I 

 have figured of L. 'phitonia^ PI. XIII, Figs. 5, 6. But it is more linear, the 

 secondaries are arched along the borders and are parallel, not flexuous, 

 more distinctly camptodrome. Other leaves figured by Heer are much 

 smaller, and some have the nervation better pi-eserved, with the areolation 

 like that of L. plidonia.

Seeds small, oblong, obtuse, attached to a short ])edicel, narrowed at 

 base, enlargeil above into a flat support of the seed, marked like it by five 

 points of corresponding vascular scars. 



This fruit is only half as large as that of L. macrocari)a, but it has the
