14 (JiEOLOGICAL SURVEY OF THE TEREITORIES. 



T}. sv, Figs. 1 and 2. A large leaf, 4 inches broad in its widest part, at 

 least 6 inches long, broadly ovate, lanceolate pointed, rouuded to the 

 petiole; borders entire, undulate; medial nerve thick, secondary veins 

 about 12 pairs, nearly equidistant and parallel, diverging from the 

 medial nerve under an angle of 60°, slightly curv^ed or nearly straight 

 to the borders, where they become obsolete ; lower secondary veins 

 branching outside. This species is like the former by the general form 

 of the still larger, longer leaves, from which it differs, however, by its 

 secondary veins, more numerous, less distant, parallel, and by the 

 borders entire. Its nervation is similar to that of Populus balsamoides, 

 as figured by Gaudin, Fl. Ital., 1st Mem., PI. iii. Fig, 1, for the branch- 

 ing and anastomosing of the secondary veins, and Fig. 4, for parallel, 

 less distant veins ; the leaf is of a thick texture. 



QuERCUS CHLOROPHYLLA, Heer. A specimen, representing a coria- 

 ceous smooth leaf, runcinate horizontally, without trace of secondary 

 veins or of tertiary nervation ; apparently ovate and entire, the borders 

 being imbedded in the stone. A small leaf upon the same specimen in- 

 dicates more clearly its ovate form, marking identity with Heer's Fl. 

 Ter. Helv. II, PL Ixxv, Fig. 8. The medial nerve is proportionally 

 broad. 



FiGus ULMIFOLIA, S}). nov, Lcaves round-oval, 3 inches wide, some- 

 what longer, with entire undulate borders, at least near the base, where 

 only they are observable ; medial nerve thick and grooved ; j)etiole 

 short and hooked ; secondary veins more or less distant, parallel, open, 

 (angle of divergence, 60°,) joining the medial nerve in a short, down- 

 ward curve, or slightly decurrent, straight, or flexuous to near the bor- 

 ders, where they curve upward, with sometimes one outside branch ; 

 nervilles oblique to the veins, flexuous, undistinct. The borders of tlie 

 leaves rounded downward, abruptly curve in descending to the petiole, 

 the lower pair of veins following the same curve. The species is repre- 

 sented by a number of specimens, all more or less incomplete, with the 

 upper part of the leaves mostly destroyed. Their general outline 

 resembles that of some leaves of Alnus Kefersteinii, Gopp., differing, 

 however, by entire borders and more open secondary veins. Its nearest 

 relative is F. horealiSj Heer, Fl. Bait., p. 74, PI. xxi, Fig. 11, differing 

 equally from this species by more open veins. 



Plat ANUS Guillelm^, Gopp. The same form as the leaf figured 

 in Heer's Fl. Arc, II, PL xlvii, Fig. 1. 



Laurus padata, (?) Lsqx., Trans. Am. Phil. Soc, vol. XIII, p. 418, 

 PL xix, Fig. 1. All the specim.ens which I refer to this species have 

 only the lower half of the leaves with obsolete nervation. They are 

 most alike, 12 in number, indicating an obovate or oblanceolate cori- 

 aceous leaf, gradually tapering downward to a thick medial nerve. The 

 few distinguishable secondary veins are thin, and have the same direc- 

 tion as in the species quoted above. This is not sufficient to warrant 

 identity. These remains might be referrable to Fersea lancifoUa, Lsqx., 

 loc. eit, Figs. 3 and 4. 



CiNNAMOMUM MissisSiPPiENSB, Lsqx., loG. cit, p. 418, PL xix, Fig. 

 2. A good specimen, though merely a little more than the lower half 

 of the leaf is preserved. The leaf is still larger than the one from Mis- 

 sissippi. 



Andromeda Grayana, Heei'; Two specimens, one of wbich repre- 

 sents a whole leaf, with distinct nervation. The identity with Heer's 

 species, Eeport, p. 298, is ascertained.
