lar to tlie medial vein, and passing from it to the lateral ones, as in 

 Fig. 10. 



CiNNAMOMUM MlSSISSIPIENSE, Lsqx., Supt., p. 14. 



Fine specimens of this species, of frequent occurrence in the Ameri- 

 can Eocene, were obtained at Golden. 



CiSSUS L^VIGATUS, sp. nov. 



Leaves subcoriaceous, polished, roand-oval, abruptly narrowed or 

 broadly wedged form to the petiole, three-nerved from the base, nerva- 

 tion actinodrome retiform ; borders undulately crenate. 



The collection has many specimens, but none complete, the upper 

 part of the leaves being mostly destroyed. The leaves are petioled; 

 the two lateral veins divexge at an acute angle and branch outside, the 

 branches parallel, running to and entering the borders in dividing, 



DOMBEYOPSIS TRIVIALIS, Sp. UOV. 



The lower part of a leaf, round-cordate at base, entire subcoriaceous, 

 three-nerved, lateral veins strong, curved upwards, branching outside. 



This leaf resembles the one in Heer's Fl. Bait., i^. 74, PI. xvii. Fig. 11, 

 named Fictis Domheyopsis, which, however, has two x)airs of lateral 

 veins from the base, wiiile ours has only one. As in Heer's leaf the 

 lower part is destroyed, while the point is erased in ours, it is not pos- 

 sible to make an exact comparison. 



DOMBEYOPSIS OCCIDENTALIS, sp. IIOV. 



Leaves coriaceous, entire, cordate-acuminate, trinerved from the base, 

 superior lateral veins at equal distance, alternate or opjjosite, campto- 

 drome. 



A number of specimens of these fine leaves present all the same form 

 and characters ; 12 cent, long, 10 cent, broad, belowthe middleor toward 

 the enlarged cordate base, narowed or tapering to the point. The 

 lower lateral veins are much branched outside, 8 to 10 branches, curv- 

 ing to and along the borders ; the upper secondary veins are either 

 simple or sparingly divided by under branches, all the divisions curving 

 to and along the borders which they reach, becoming like marginal ; 

 nervilles strong, in a right angle to the thick medial nerve; the borders 

 appear somewhat reliexed. The nervation is that of Dombeyopsis grandi- 

 folia, TJng. 



Sapindus caudatus, sp. nov. 



Leaf unequilateral, entire, broadly lanceolate, tapering into a long 

 acuminate point, narrowed to the petiole on one side, rounded to it on 

 tlie other. 



The secondary veins are alternate, unequally distant, the lowest ones 

 more open, curving to and along the borders and anastomosing with 

 shorter intermediate ones. The nervation is of the same type as in 

 Sapindus falcifolivs, Heer, Fl. Helv., PL cxix, Fig. 16. I found two 

 leaves of this species j. the largest 10 cent, long, 4 cent, wide in the 

 middle.
