DESCEIPTION OF SPECIES. 79 



number of leaves referable to the same type which reinuius predominant in 

 the Tertiary. 



Remark. — Ficus Berfhoiidi is not always enlarged in the middle but lias 

 its leaves sometimes linear. In No. 463a of Sternberg's collection the leaf 

 is nan-owed to the petiole which is cm'ved and of the Ksame size as F. pro- 

 feoides (PI. XII, Fig. 2), except that the leaf is linear above the basal part, 

 l)eing 3*"" in diameter in the middle, and 2.5°'" in the upper and lower parts. 

 The direction of the secondaries is the same as in Fig. 3, but they diverge 

 in the lower part, being more open in the upper.

Ficus crassipes Heer. 

 PI. XIII, Fig. 3. 



Fl. Foss. Arct., vol. 6, 2 Abth.,p. 70, PI. xvii, Fig. Oa; PI. xxiv, Figs. 1, 2; PI. xLii, 

 Fig. 2c : PI. XLIII, Figs. 4-6; PI. XLVI, Fig. 15. 



Leaves coriaceous, broadly linear-lanceolate, tapering and decin-rent 

 to the base, quite entire ; median nerve thick; secondaries obsolete ; })etiole 

 long and thick. 



This species, represented by Heer (loc. cit.) by many leaves, which are 

 more or less well preserved but none entirely so, is easily recognized by 

 the basilar form of its leaves, which are gradually nan'owed and nan-owly 

 decurreut to a thick, median nerve, thus forming a thick or broad-winged 

 petiole. As yet I have seen only the specimen figured, showing a little 

 more than half a leaf, its lower part, of which the secondary nervation is 

 totally olisolete. The nervation and areolation as figured by Ileer (loc. cit., 

 PI. XLVI, Fig. 15), is in thin, in-egular areoles, like those of F. atavina Heer, 

 to which this species has great affinity, as well as by the form and size of 

 its leaves. 



Habitat: Ellsworth County, Kansas. No. lOOa of the collection of 

 the museum of the University of Kansas; A. Wellington, collector. 



Ficus magnoli^folia Lesq. 

 PI. XVI, Fig. 4. 



Cret. and Tert. Fl., p. 47, PI. xvii, Figs. 5, 6. 



The leaf is of the same character, only slightly smaller, as the tvjie 

 specimens which were collected in Colorado at the base of the Rocky
