Bro7igniart, Sur les Vegetaux Fossiles. 183 



belong to the division with pinnate leaves. The leaves and 

 fruits are found in distinct localities. They are altogether 

 confined to the superior formations. 



Class IV. Organs of fructification. 



Order 1. Carpolithes. Fruits and Seeds. 



2. Antholithes, Flovrers. 



Many fruits have been found in the mill-stone rock (meu- 

 liere) near Paris, and in the fresh water formation of I, 

 Wight, in clay. They are referred to G. Thalictrum. Fos- 

 sile flowers have been found only in the superior sediment 

 at Monte Bolca. They are very rare, and hard to be re- 

 cognized. They preserve only the envelopes; one, however, 

 has an ovary with three stigmas, and six divisions to the en- 

 velope, three exterior and three interior, resembling the 

 Liliaceae. 



Appendix. Fossils referable to known Genera found in 

 the superior formations. Three species of fruits referred 

 to G. Chara, two found in the mill-stone of the superior 

 fresh water formation, and one in the fresh water formation 

 inferior to the coarse limestone near Paris. A species of 

 Juglans intermediate to the regia and nigra found in the 

 superior sediment near Turin. Three species of cones, of 

 G. Pinus, one found in the sea-shell formation, at the foot 

 of the Appenines in Placentia, carbonated and mixed with 

 sea-shells, bones of cetacea and carbonated wood. 2d 

 found in the coarse limestone at Arcueil, entirely destroy- 

 ed, leaving only its impression in the mould. 3d in the supe- 

 rior sediment in Ardeche, only an imperfect mould remaining. 

 All the fruits of the superior formations are distinctly refer- 

 able to known Genera; of stems and leaves only a few spe- 

 cies can be so referred, viz. the Equisetum Brachyodon, found 

 in the coarse limestone near Paris — and a specimen in the 

 mill-stone of Lonjumeau, resembling very exactly the cree- 

 ping submerged roots of Nymphea Alba, after the fall of 

 the radicles and petioles. 



Recapitulation. 1. The formations of superior sediment 

 including plastic clay resting on chalk, the coarse limestone, 

 mill-stone rock, and gypsum of Paris — the limestone of M. 

 Bolca, the shell-limestone of the Appenines, the fresh water 

 formations above and below the coarse limestone, lignites, 

 &c. contain fossile vegetables belonging to the G. Exoge- 

 nites, Endogenites, Culmites, Lycopodites, Palmacites, Fu-
