DESCRIPTION OF SPECIES. 85 



2"" long, 3""" to 4"'" broad, is alate, formed by tlie continuation of the median 

 nerve abruptly enlarged at the base of the leaves into a broad, flat lamina. 



By the form and aspect of the leaves the species is related to Ficns 

 humelioidcs Ett. (Kreideflora v. Niederschoena, p. 251, PI. ii, Fig. 6), espe- 

 cially differing by the obtuse (not emarginate) apex of the leaves and by 

 the foliate petiole. Its affinity, as shown by the form of the leaves, is still 

 more marked with Ficns Mudgei Lesq.

Feuits of Ficus. 

 PI. X, Figs. 7, 8. 



Comparable to or rather much like two fruits of Ficus figured by Heer 

 (Fl. Foss. Arct., vol. 3, pt. 2, PI. xxx), on which he remarks (p. 109) that 

 these fruits found with the leaves of F. protogmi Ett. show such a likeness 

 to fruits of Ficus that their determination can not l)e doubtful. The leaves 

 of F. protogcea Ett. have not yet been observed in the Dakota Group, but 

 its flora has a large number of leaves of Ficus of the same type ; F. glas- 

 coena Lesq., for example, diff'enng merely from F. protogcea by the large 

 size and the more ovate form of the leaves. 



Habitat: Four miles southwest of Brookville, Kansas. No. 4057 of 

 the collection of Mr. R. D. Lacoe. 



Ficus lanceolato-acuminata Ett^ 

 Pi. XIII, Fig. 4. 



Foss. Flora v. Sagor, pt. 1, p. 182, PI. vi, Figs. 3, 4. 



Leaves coriaceous, polished, lanceolate, gradually acuminate, naiTowed 

 to the short petiole, entire; median nerve strong; secondaries close, curved 



' This species was first described by Prof. Lesquereux under the name of Laurus primigenia Ung. 

 var. cre(aceo Lesq., and was transferred only a short time before his death. His note is as follows: 

 "PI. XIII, Fig. 4, which I have referred as Laurus primigenia cretacea, has the same form, size of leaf, 

 and nervation as Ficus lanceolatoacuminata Ett. (Flora of Sagor, PI. vi, Figs. 3, \). See also Engel- 

 hard, Nova Acta, vol. 43, PI. xiv. Fig. 3 of F. lanceolata. Must be this, though the secondaries are a 

 little more distant." The original description and comparisons are retained as ho wrote them. — F. H. K.
