texture, and the nervilles are not distinct as in tlie specimen from 

 Greenland. This is probably the result of the coarseness of the stone. 

 One of the specimens bears two fragments of leaves of this species, one 

 of which has the secondary veins more. distant, as in 8. Groenlandica, 

 while the other has them much more approached to each other, just as 

 they are in 8alix BJieana, Heer, figured on the same plate, Fig. 12, with 

 nervilles discernible. I consider both species as identical. 



Myrica AMBiauA, sjp. nov. A species represented by three incom- 

 plete specimens. Leaf api^arently long, (point broken,) linear -lanceolate, 

 narrowed to the base, in an outward curved line, about 2 inches broad, 

 or less, the other specimens being narrower, with borders distantly and 

 obtusely serrulate; medial nerve, broad, narrowly furrowed; secondary 

 %^ins in right angle to the medial one, thick at the base, much thinner 

 in the middle, where they branch, anastomosing with divisions of the 

 upi)er and lower veins, and also, with shorter intermediate ones, which 

 separate them. ISTearer to the borders the nervation becomes indistinct. 

 It is distantly related to Myrica Banlcsicefolia, Ung., as figured Fl. Alas., 

 PI. ii, Fig. 11. 



CoRYLUS McQuARRYi, Hecr. Mixed with, fragments of Populus leuco- 

 pliylla, Ung. 



QuERCUS Ellisiana, sp. nov. Leaves ovate-lanceolate, pointed, or 

 obtusely i^ointed ; round cuneate at base, wdth borders marked with short, 

 distant angular teeth becoming obtuse toward the i)oint ; medial nerve 

 deeply marked; secondary veins, eight to ten pairs, emerging at an open 

 angle, 55°, curving in ascending to the borders and entering the teeth, 

 The lowest pair branch once or twice downward ; tne second pair has 

 sometimes one inferior branch near its point; all the other veins are sim- 

 I)le ; nervilles, undistinct, crossing the veins at right angles. This spe- 

 cies is allied to Quereus Pseiido-almis, Etting., (Bil., Fl.,) which has more 

 deeply marked and more acute teeth, with secondary veins at a more 

 acute angle of divergence and more distant. 



QuERCUS Pealei, sp. nov. A small coriaceous, short, petioled leaf, 

 IJ inches long, ovate in outline, cuneate and entire to the petiole, more 

 abruptly narrowed from above the middle into an obtuse point, and 

 there obtusely and distantly crenate; medial nerve deeply marked, 

 like the secondary veins ; four to five pairs in acute angle, (30°,) curving 

 in going to the borders, where they enter the teeth, except the lowest 

 pair, which curves upward, follows the borders, and unites by ramifica- 

 tion with branches of the second pair. It is a fine species, somewhat 

 like Quercus fagifoUa, Gopp., (Schossnitz, Fl., p. 14, PL vi, especially 

 Fig. 9,) from which it differs by the cuneate rounded base of the leaves, 

 the more deeply marked teeth, and more curved secondary veins. 



QuEROUS Godeti, Heer. Two specimens of leaves, with all the 

 characters of this species, as described by Heer, (Fl. Ter. Helv., II, 

 p. 50,) especially resembling PI. cli. Fig. II. The borders of the leaves 

 appear only irregularly serrulate, and not doubly so, as marked in the 

 figure ; but the coarseness of the stone obliterates the details. By the 

 borders, unequal at the base, and by the nervation, these leaves, like 

 those of Europe, seem referable to Juglmis. The areolation is undis- 

 tinct. 



Quercus Laharpi, Gaud., (Fl.Ital., 2 Mem., PL iii, Fig. 5, 10.) The 

 leaves referable to this species differ only from it by their smooth 

 surface, and the secondary veins, more numerous, sixteen pairs at least, 

 nearer to each other, and more curved in passing out to the borders. 

 According to the author the surface of the leaves of his species is
