This memoir, published in the ' Transactions of the Carlsruhe Na- 

 tural Sciences Society/ vol. i., commences with a notice of the re- 

 searches of W, P. Schimper and the author respecting the Lower 

 and Middle Coal-formation of the Grand-Duchy of Baden ; and, after 

 an enumeration of the several Palaeozoic florae found in the Black 

 Forest (namely, 1. that of the Lower Coal-formation or " Grau- 

 wacke," at Badenweiler and Lenzkirch ; 2. the Middle, at Berg- 

 hampten ; 3. the Upper, at Baden, Oppenau, Hinterohlsbach, and 

 Geroldseck ; and 4. that of the Bothliegende or lowest part of the 

 Zechstein-formation, at Dixrbach, Oberkirch, and Baden), proceeds 

 to treat of the geological conditions of the Upper Coal-formation at 

 different places: — 1. Baden-Baden; 2. Lierbach Valley, near Op- 

 penau ; 3. Hinterohlsbach, between Oppenau and Gengenbach ; and 

 4. Hohengeroldseck by Lahr ; and then enters on the description of 

 some species ; namely, PterophyUuni hleclmoide^, Sandb., Palmacites 

 crassinervius, Sandb., and Neurojiteris Loshii, Ad. Brongn., which 

 have three good plates devoted to their illustration. P. hlechnoides 

 is the second species of this genus known in the Coal (P. gonor- 

 rhachis, Goepp., being the other) ; whilst P. Cottcmnum, Gutb., is 

 found in the Red Permian Marlstone near Zwickau. No Palm, 

 besides the Palmacites here noticed, has been known for certain 

 in the Coal; but Geinitz had his GuUehnites Pennianus from the 

 next succeeding formation. 



Of Newopteris Loshii, Prof. F. Sandbergcr remarks that the 

 great variation in the terminal leaflets of the frond in this imjjortaut 

 species, not weU fig-iired by Brongniart, and its wide geographical 

 range, have induced him to illustrate it. The earliest (seedling) 

 fronds, though rare and imperfect, are evidently the same as Cijdo- 

 pteris remformis, Brongn. M. Loshii is found, \fit\i I'tcrophi/IIum 

 hlechnokles and Cordaitcs borassifollus, in great abundance at Holz- 

 platze; but it ranges throughout the Coal-measiu-es of different 

 regions.
