Biospijros anceps Heer., Fl. Tert. Helv. Ill, p. 12, PI. CII, figs. 15-18; 

 V, Sybir. Fl., p. 42, PI. XI, fig. 7. 



The leaves agree by all the characters with Heer's species especially 

 similar to figs. 16, 17 of Fl. Helv. I. c, the smaller leaf being of the same 

 size as fig. 16. The other specimen, which is fragmentary, is much like 

 fig. 7 of the Siberian Fl. The leaves are broader than in D. Alaslcana; 

 the lateral nerves more distant, &c.

Ericint}^. 



Vaccinium reticulatum, Al. Br., Heer., Fl. tert. Helv., Ill, p. 10, PL CI, 



fig. 30. 



Leaves petiolate, oval, very entire, obtuse at the apex, narrowed at 

 the base in rounding to a short alate petiole ; lateral nerves open, few, 

 interspersed with tertiary shorter ones ; surface deeply reticulate. 



The leaves from their size, shape, and nervation corresjtond with those 

 described by Heer, I. c, the only difference being that one of the leaves 

 I had for examination, the largest, has the short petiole alate. In fig. 

 30 of Heer, the petiole seems also bordered in the upper part by the 

 decurrent base of the leaf, but the appearance is less distinct. More- 

 over, there are other leaves in the same collection of Mr. Dall which are 

 smaller and with naked petiole. The difference is not therefore of 

 specific value.

Cornus orhifera Heer., IJ. S. Geol. Eep., VII, p. 243. 



The specimen referable to this species has the lateral nerves curving 

 inward along the borders, anastomosing with the upper ones by nervilles 

 in right angles, as in Heer, Fl. tert. Helv., pi. C V, fig. 16. Heer has also 

 described the species from Si)itzbergen specimens.

Magnolia Nordenskidldi Heer., Beitrage zur foss. Fl. Spitzb. (Fl. Arct. 

 IV), p. 82, PI. XXI, fig. 3 5 XXX, fig. 1. 



Leaves large, thickish, oval, obtuse, entire, emarginate, or shortly 

 auriculate at base; secondary nerves distant, curved in traversing the 

 blade, forking near the borders. 



From the numerous well preserved specimens of this beautiful spe- 

 cies, I have been able to complete the diagnosis of Heer, made from too 

 fragmentary leaves. The leaves are longer than those of M. oralis, 

 Lesqx., to which Heer compares this species, and also subauriculate at 

 base or emarginate ; the surface is rugose, crossed in right angles to the
