NO. 2151. FOSSIL PLANTS FROM FLORISSANT— KNOWLTON. 277 



cata. The present location of the type of C. truncata in unknown, 

 though it should not be difficult to identify it if found in Fort Union 

 material, when its identity with, or distinctness from C. parvifolia will 

 have to be determined. 



VICIA. species. 



Plate 23, fig. 4. 



The Hambach collection includes a specimen — the one here 

 figured — that appears referable to a tendril-bearing plant of the type 

 of Vicia, and it is so referred. 



Type.— C&t. No. 34,740, U.S.N.M. 



ROBINIA BRITTONI Cockerel!. 



Plate 24, fig. 2. 

 Rohinia brittoni Cockerell, Amer. Jour. Sci., vol. 36, 1908, p. 543, fig. (in text) 8. 

 Cat. No. 34,767, U.S.N.M. 



The Scudder collection contains the splendid specimen here fig- 

 ured, which is much more complete than the type. 



CYTISUS FLOKISSANTINUS Lesquereux. 



Plate 21, fig. 5; plate 23, fig. 3; plate 24, fig. 4. 

 Cytlsus florissanitnus Lesquereux, Rept. U. S. Geol. Surv. Terr., vol. 8 (Cret. 



and Tert. Fl.), 1883, p. 200, pi. 39, fig. 14. 

 Cassia fischeri Heer. Lesquereux, Rept. U. S. Geol. Surv. Terr., vol. 8 (Cret. 



and Tert. FL), 1883, p. 202. 



Cat. Nos. 50,296, 50,297, 50,298, U.S.N.M. 



This species is introduced for the purpose of showing that the 

 leaves described by Lesquereux from the Lacoe collection as Cassia 

 fischeri Heer, are really leaflets of Cytisus fiorissantinus Lesquereux, 

 which are described and figured on another page of the Cretaceous and 

 Tertiary Floras. There are three specimens representing two leaflets 

 and a counterpart, all bearing the original No. 42 of the Lacoe col- 

 lection ; they are here figured for the first time. 



DALBERGIA? MINUTA, new species. 



Plate 24, fig. 3. 



Leaflet long-petioled, membranaceous, obcordate in shape, cuneate 

 to the slightly decurrent base, deeply emarginate at apex, margin 

 perfectly entire; secondaries about four pairs, the lowest pair arising 

 near the base and ascending along the margin; other pairs above the 

 middle of the blade, at a lower angle of divergence. 



Ti/pe.— Cat. No. 34,742, U.S.N.M. 



This little leaflet, which is nearl}^ perfect, is only 18 mm. long, in- 

 cluding the petiole 6 mm. long; the width is 11 mm. It is exactly 

 obcordate in shape, with the base slightly decurrent halfway down 

 the petiole.
