texture, and the nervilles are not distinct as in the si)ecimen 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 feach other, just as 

 they are in Salix EJieana, Heer, figured on the same plate, Fig. 12, with 

 nervilles discernible. I consider both species as identical. 



Myrica ambigua, sp. nov. A species represented by three incom- 

 plete specimens. Leaf apparently 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 

 veins in right angle to the medial one, thick at the base, much thinner 

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

 upper and lower veins, and also with shorter intermediate ones, which 

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

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

 PI. ii, Fig. 11. 



OoRYLUS McQuARRYi, Heer. Mixed with fragments of Fopiiliis leuco- 

 phylla, Ung. 



QuERCUS Ellisiana, Sj9. uov. Leaves ovate-lanceolate, pointed, or 

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

 distant angular teeth becoming obtuse toward the point ; 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 ; the 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 Qiiercus Pseudo-alnus, 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. 



QuEROUS Pealei, s}). nov. A small coriaceous, short, petioled leaf, 

 IJ inches loDg, ovate in outline, cuneate and entire to the i^etiole, 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, (oO^,) 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 fagifolia^ 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. 



QuBRCUS GoDETi, Heer. Two specimens of leaves, with ail the 

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

 p. 50,) especially resembling PL cli. Fig. 11. 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 Juglans. The areolation is undis- 

 tinct. 



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

 leaves referal)le to this species differ only from it by their smooth 

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

 nearer to each other, and more curved in [)assiiig out to the borders. 

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