Sequoia Langsdorfii, Heer, Fl. Tert. Helv., p. 54, PI. xxi, Figs. 3 



and 4. 



B}^ the obtusely-poiuted leaves, their decurrent base, their size, &c., 

 our specimens are evidently referable to this species. - Fragments of 

 conifers, though very abundant in the bottom clay of the lignite beds, 

 are rarely found in the shale overlying them. 



Phkagmites Oentngensis, A1. Br. 



Numerous fragments of leaves. 



Flabellaria eoce:xica, sp. nor. 



Petiole long, flat, smooth, truncate at the point of union of the rays. 



The petiole is broken two inches below its top, which is exactly flat 

 or truncate ,• the rays, about 30, are much diverging and expanding, 

 from 1 mill, wide at the point of union with the petiole, to 3 cent, at a 

 short distance above w^here they separate ; primary veins eight, large, 

 obtuse ; space between them irregular, marked by 12 very thin obsolete 

 secondary stride. By the trunca'te i)oint of the rachis the species is like 

 Fig. 4, PI. i, of Flora Haringa., Ett., which the author considers as an 

 intermediate form between F. Martii, Ung., and F. rapJiifoUa, Sterub. 

 Our species, however, has the top more straightly truncate, with a flat 

 smooth petiole. 



Sabal Ca]vipbellii, {'■') Newb. 



Eepresented by fragments of leaves or rays with obsolete nervation, 

 and fruits referable to Carpolithe^ palmarum, Lsqx. 



Smllax obtusangula (?) Heer, Fl. Tert. Helv. II., p. 1G6, PL cxlvii., 



Fiff. 25. 



*&• 



Leaf large, coriaceous, entire, hastate-cordate, seven-nerved from the 

 base. 



The leaf is too imperfect for precise determination ; the lower part 

 only is jireserved. The lobes are still longer and less obtuse, or slightly 

 more acute than in the quoted figures of this species. It is probably a 

 new one. The division of the veins and their direction in the auricles 

 cannot be seen. 



Caulinites spaeganioides, sp, nov. 



Stem 12 mill, broad, flattened, horizontally wrinkled or warty, with 

 distantly articulations, and comparatively large rootlets; branches 

 alternate, distant, bearing sessile small ears, or groups of flowers. 



Fragments of these stems are numerous. The branch-scars are deep, 

 round, marked in the center by a mamilla, either smooth, or with rays 

 diverging, star-like. Smaller scars of the same form mark the point of 

 attachment of ovate-cylindrical bodies, Smill. in diameter, club-shaped or 

 ovate-pointed, marked by protuberances like a receptacle with seeds. 

 One of the branches bears three oval-pointed buds at a distance of 1 

 inch ; one of them is open and appears to contain small seeds compressed 

 between ovate, striate, thin involucels. A specimen ^ith fragments of 

 stems and branches of this sj^ecies is covered wi^th small seeds, i>laced
