ART. 19 PLANT AND INSECT FOSSILS COCKERELL 5 



Family ARALIACEAE 



ARALIA WYOMINGENSIS Knowlton and Cockerell 



Green River Eocene, Roan Mountains, Colorado, 1922, Station 8, 

 half a mile east of our camp at head of Ute trail. A leaf of the same 

 size as that figured by Knowlton,^ but differing from Knowlton's 

 figure and agreeing with Newberry's in having the principal lateral 

 veins arising some distance above the base of the leaf. 



Family FABACEAE 



DALBERGIA KNOWLTONI, new species 



Plate 1, fig. 3 



Leaflet apparently coriaceous, oval with broadly angulate slightly 

 inequilateral base and deeply emarginate (in the type strongly in- 

 equilateral) apex; margins entire. Length 40, width 25.5 mm. 



Green River Eocene, Roan Mountains, Colorado, 1922, Station 8, 

 near head of Ute trail. 



HoJotype.— Cat. No. 36854, U.S.N.M. 



This is evidently identical with I^owlton's D. retusa, but as that 

 name has been used twice, earlier, for living species, I take my speci- 

 men, which is better than Kjiowlton's, as the type. 



AMORPHA UTENSIS, new species 



Plate 2, fig. 6 



Leaflet 12 mm. long, 5 mm. across near apex, cuneate, with entire 

 margins, apex broadly truncate and strongly mucronate; petiolule 

 rather stout 3 mm. long. 



Green River Eocene, Roan Mountains, Colorado, 1922. Station 

 1, near head of Ute trail. 



Holotype.—Q2it. No. 36855, U.S.N.M. 



This leaflet is exactly as in Amorpha, but unusually cuneate at 

 base. 



Family CLETHRACEAE 



CLETHRA(?) LEPIDIOIDES, new species 



Plate 2, fig. 7 



A slender flexible raceme, with crowded small fruits in the manner 

 of Glethra alnifolia Linnaeus. Fruits globose, about 2.3 mm. in 

 diameter, on short petioles, apparently enclosed in a calyx; raceme 

 as preserved about 35 mm. long (but the end is missing) and 4 to 

 5 mm. wide, pure black.
