GEOLOGICAL SUEVEY OF THE TEEEITORIES. 15 



Two nearly entire leaves of this species, of exactly the same form and 

 characters as those described from specimens of the Mississi})pi Tertiary. 



Magnolia Hilgakdiana, Lsqx., loc. cit, p. 421, Pi. xx, Fig. 1. The 

 borders of the leaves which 1 refer to this species are mostly erased. 

 These leaves are oblong, not enlarged npward, as in the former species, 

 abruptly rounded downward to the petiole ; secondary veins numerous, 

 parallel, open, curving at a short distance from tlie borders and along 

 them. The general outline of these leaves and their nervation agree in 

 in every point with description and figure, loc. cit. 



Among the undeterminable fragments from this locality, there are 

 still some referable to another species of Magnolia, especially resembling, 

 *by obtuse point and nervation, Magnolia ovalis, Lsqx., also of the Mis- 

 sissippi Tertiary. 



Teeminalia eadobojensis, Heer, not IJug. The same leaf, in all 

 its cbaracters, as the one figured in Fl. Ter. Helv., PI. cviii, Pig. 12. 

 It is entire, obovate, gradually tapering downward to the base of the 

 medial nerve ; secondary veins distant, opposite or alternate, irregular 

 in distance and direction, at first curving outside from the medial nerve, 

 and then ascending nearly straight to the borders, camptodrome. Traces 

 of strong nervilles perpendicular to the secondary veins, and also of a 

 few intermediate tertiary shorter veins, are obscurely seen on the speci- 

 men, the substance of the leaf appearing somewhat thick. Unger's 

 figure of this species in Chloris, PI. xlviii, Fig. 2, represents a much 

 larger leaf, with secondary veins more numerous, equally distant, par- 

 allel, and an ultimate nervation finely marked, as in a leaf of a thin 

 texture. These differences may be considered as specific. 



Ehamnus obovatus, Lsqx. The leaf is smaller than those described 

 from Marshall coal in Am. Jour. Sci. and Arts, vol. 45, p, 207. The 

 peculiar form of the obovate or oblanceolate leaves with closely ap- 

 proached, iiarallel, thick secondary veins identify them easily. 



Ehamnus DELETUS, (!) Heer, Fl. Ter. Helv., p. 79, PL cxxiii.. Figs. 19- 

 23. Two broken specimens are referable to this species. They rep- 

 resent ovate, slightly cordate leaves, with 8 to 10 i)airs of deeply marked 

 secondary veins, slightly curving in passing to the borders, campto- 

 drome with distinct fibrilles. Tlie point of the leaf is destroyed and 

 thus the essential character of this species — borders serrulate near the 

 point — is not ascertainable. 



' Berghemia paevieolia, Lsqx., Am. Jour. Sci. and Arts, vol. 45, p. 

 207. The name given to the species is not appropriate, as a new speci- 

 men from this locality has a leaf as large as in B. voluhilis, D. C. From 

 this it differs by broader leaves and secondary nervation more open, 

 the veins slightly arched in asc^iding and bending npward before 

 reaching as near the borders. This species is still more closely allied 

 to J5. nmltinervis, Heer, Fl. Ter. Helv., p. 77, PI. cxxiii. Figs. 9-18, dif- 

 ering merely by the secondary veins, which, in the American species, 

 are open from the medial nerve, while in Heer's species they join the 

 nerve by a downward curve. 



Ei-iAMNUS FiscHEEi, sp. nov. Leavcs thickish, large, 4 inches long, 

 3 inches broad, rhomboidal, obtuse and entire; medial nerve, thick, 

 grooved, secondary veins open, (angle of divergence, 60°,) equidistant, 

 10 to 12 pairs, parallel, straight to the borders, where they abruptly 

 curve, camptodrome. By the form of the leaves and the straight sec- 

 ondary veins this species is related to Ehamnus aizoon, Heer. The nerv- 

 illes "are not distinguishable. 



Xanthoxylum dubium, sp. nov. A small oblong leaf 3 centimeters 

 long, 1^ centimeters broad, with borders entire or wavy crenulate, nearly
