which this species is named, T have placed it with the Proteacea;. I am, 

 however, still uucertain in regard to the true relation ot these remarka- 

 ble remains. There is, as said aboxe, in the position and the subdivis- 

 ions of the leaflets a remarkakle affinity with those of some species of 

 ferns, and at the same time a discrepancy with what is remarked in the 

 segments of the leaves of Lomatia and other species of laciniate Pro- 

 teacece. In the fossil plant the decurrent base forming a wing of the 

 rachis, has the same character of nervation as the leaflets, while in the 

 basilar segments of the Proteacece the winged part is generally without 

 visible veins, or rather veined lengthwise. Moreover, there seems to be 

 a kind of anomaly in the presence of plants of the so called Australian 

 types in a vegetable group where the characters of the present American 

 flora are so predominant, or in connection with species of Fagus, Lyrio- 

 dendron, Platanus^ etc. The leaves described under the name of Prote- 

 oides are as yet not positively referable to the Proteacece, their nervation 

 being still unknown ; and thus we should have to admit this Lomatia ? 

 as the only representative of an Australian type among a large number 

 of forms of different affinities. 



This species has been found originally in very fine specimens by Prof. 

 B. F. Mudge, in Southern Kansas. I have lately received a small frag- 

 ment only from Mr- H. 0. Towner, found near Clay Center, Kansas. 



Proteoides daphnogenoides, Heer, Cret. Flora, p. 85, PL XY, 



figs. 1, 2. 



Leaves ovate-lanceolate toicard the base, gradually tapering uptvard to a 

 long scythe-shaped acumen, entire^ smooth and coriaceous; middle' nerve 

 narrow y secondary veins obsolete, feio, ascending at a very acute angle from, 

 the middle nerve and following the borders. 



Proteoides acuta, Heer, Cret. Flora, p. 86, PI. XV, fig. 3: 



PL XXVIII, fig. 13. 



Leaves coriaceous, linear -lanceolate, narrowed to the base and gradually 

 so to a scythe-shaped point ; borders undulate ; middle nerve strong, sec- 

 ondary veins obsolete. 



Proteoides g-reville^formis, Heer, Cret. Flora, p. 86, PL XXVIII, 



fig. 12. 



Leaf coriaceous, small, enlarged above the base, linear -lanceolate, flexuous ; 

 borders entire ; middle nerve thicJc ; secondary veins alternate, thin, aero- 

 drome, ascending nearly parallel to the borders and slightly curving 

 inward. 



Embothrites ? DAPHNEOIDES, Lesqx., Cret. Flora, p. 87, PL XXX, 



fig. 10. 



Leaf coriaceous, 'polished, oblong, narrow, gradually narrowed dotcnward 

 and decurrent to the enlarged middle nerve; borders slightly refiexed ; nerva- 

 tion pinnate ; lateral veins opposite, close, at a very acute angle of diver- 

 gence. 



This fragment of leaf is of an uncertain attribution. 



ASARIXE^. 



Aristolochites dentata, Heer, Cret. Flora, p. 87, PL XXX, fig. 6. 

 Leaf nearly round, thickish, split from the base of the petiole to the 

 borders, undulate-crenate, three-nerved ; secondary veins curving and aiias- 

 tornosin^ in large, oval, angular meshes.
