 Laurus primigenia Ung.? Hollick, Trans. New York Acad. Sci., vol. 12, 1892, p. 33, pi. 2, fig. 20; pi. 3, fig. 3. 

 Magnolia alternans Heer, Hollick, Bull. New York Bot. Gard., vol. 2, 1902, p. 405, pi. 41, figs. 4, 5. 



Whatever may be thought of the fragmentary specimens represented by figs. 5-8, 

 there can be but little doubt that figs. 3, 4 are referable to a form of this species, 

 intermediate between the broad one shown in Lesquereux's fig. 1, pi. 10, and the 

 narrow one depicted in fig. 14, pi. 28 (loc. cit.). 



The fragmentary specimens were the first ones found by me, and they were 

 somewhat doubtfully referred at that time in part to Laurus and in part to Mag- 

 nolia (loc. cit.). The more perfect specimens subsequently brought to light, how- 

 ever, have afforded opportunity for more satisfactory comparison and identification, 

 showing the characteristic thick midrib and obtuse apex of this species. 



It is of interest to note that Lesquereux, in his discussion (loc. cit.) also refers to 

 the resemblance between his specimens and certain species of Magnolia, particu- 

 larly to M. speciosa Heer. a

This species belongs in the same group with L. teliformis Lesq., 6 and L. Knowl- 

 toniana Lesq., c but it is much larger than the former and much less robust than the 

 latter. The type specimen only is known, the figure of which is here reproduced.

 in Mus. New York Bot. Gard.
