28 DESCRIPTIONS OP FOSSIL PLANTS. 



Ficus miciophylla Lx. 



Ono specimen; Museum number, 2473. 

 Ficus shastensis n. sp. Plate xi. fig. 3. 



Leaf subcoriaceous, oval, a cuminate, narrowed to an enlarged slightly 

 winged petiole; secondaries obliquely curved, anastomosing in simple 

 bows near the borders; areolatiou very small, closely gran u lose, verru- 

 cose. 



The leaf 6 cm long, 3i' m broad at the middle, is tapering upward to a 

 short acumen, rounded and narrowed downward about in the same de- 

 gree to a broad petiole IS 11 "" long, enlarged at the point of attachment. 

 In shape an 1 size the leaf is like that of Persea Braunii Ileer (fig- 

 ured in PI. Tert. Helv., vol. iii, PI. cliii, fig. 2), and the distribution of 

 the secondaries is also the same, lint the leaf is covered by a verrucose 

 surface exactly similar to that of Ficus scabriuscuia Heer /. c. (ii, p. G4), 

 which, as the author says, isotten marked upon the leaves of species of 

 Ficus, rendering their surface rough, and covering the areolatiou. This 

 kind of verrucose process is quite distinct under the glass. The bows 

 of the secondaries along the borders are also typical of species of Ficus 

 as well as the broad petiole. 



Two specimens; Museum number, 2478. 



10. 



Lassen County, Oal. Collected by Mr. J. S. Diller. Age, Eocene 

 (Laramie). 



Aralia lasseniana, n. sp. Plate xiv, fig. 5. 



Leaflet linear, oblong, rounded at base to a short petiole, entire or un- 

 dulate on the borders, subcoriaceous, peuniuerved ; secondaries distant' 

 and equidistant, parallel, opposite, at a broad angle of divergence, 

 strongly marked like all the details of nervation, camptodrome, nerv- 

 ing in passing toward the borders and following them, by anastomos- 

 ing by curves and nervilles, to the upper one; nervilles strong, at right 

 angles to the medial nerve and to the secondaries, irregularly branch- 

 ing and anastomosing, forming large polygonal meshes. 



The leaflet broken at apex, is 8 cni long, 1£ to 2 rm broad near the base, 

 3 c,n broad at the upper part where it is broken. 



As yet I have seen nothing in the North American fossil flora to 

 which this leaf might be related. It is comparable in all its characters, 

 form, and nervation, to Aralia robusta (Sap. Sez. Fl., p. 3SG, PI. x, fig. 7). 

 It has also the aspect of leaves of Laurus, e. g., L. Reussii, L. prim'ujenia 

 var., but is quite distinct by its distant parallel secondaries. The leaf- 

 let, not entirely preserved, seems to be part of a compound leaf. 



One specimen; Museum number, 2425. 



Magnolia Inglefieldi Heer. 



The description of the species in Heer (Fl. A ret., 1, p. 120) is as fol- 

 lows: " M. leaves large, coriaceous, smooth (levigati), very entire, ellip-
