4 GEOLOGICAl MEMOIRS. 



3. On the Ploea. of the Brown Coal of Sagor, Carniola. 



By Professor C. von Ettingshaxtsen-. 

 [Imperial Academy of Sciences, Vienna, April 13, 1871.] 



Up to the year 1820 only 9 species belonging to this flora were 

 known, and these were described by linger in his ' Genera et 

 Species Piantarum fossilium.' In 1850 Prof. C. von Ettingshaiisen 

 commenced a careful investigation of this Flora, representatives of 

 which are now known to occur in fourteen distinct localities at 

 Sagor and in the neighbouring districts of Carniola and Styria ; and he 

 has now completed the first part of his description, embracing the 

 Thallophytes, Vascular Cryptogams, Gymnosperms, Monocotyledons 

 and Apetala. A species of Sphceria from Sagor is most nearly 

 allied to Sphceria annulata from Greenland. A Plorideau Alga, 

 analogous to Laurencia, indicates the presence of salt water, and is 

 the only marine plant of the flora of Sagor. 



The Gymnosperms number 15 species ; and among them is an 

 Actinostrobus of Australian type, the six-valved strobiles of which has 

 been found in two localities. The prevalent conifers are Olypto- 

 strobus europceus and Sequoia Couttsice, the branches, strobiles, and 

 inflorescence of which have been met with at nearly every locality. 

 Other species of Sequoia are S. Langsdorfi, S. Tournali, and S. Stern- 

 bergi. A new and remarkable fact is the presence of a Cunning- 

 hamia in these Tertiary deposits. A fragment of a branch strikingly 

 similar in every respect to Cunninghamia sinensis, P. Brown, has 

 been found in a quarry near Savine. The genus Pinus includes 

 six species, each generally represented by complete clusters of 

 leaves and by the cones. 



As at Sotzka and Haring, the number of Gramineoe is very small. 

 The Najadese are remarkable in numbers and forms, including two 

 species of Potaniogeton, one of Zostera, one of Najadopsis, and one of 

 Nwjadonium, all inhabitants of fresh water.' The Pandanese and 

 Palms are each represented by one species. Oasuarina sotzkensis, 

 which* is frequent in all Tongrian and Aquitanian floras, occurs 

 here, and with it a new species, nearly allied to the existing G. 

 quadrivalvis. The other apetalous families of the Sagor flora are 

 represented as follows: — Myricacese by 3, Betulaceae by 6, Cupu- 

 liferae by 15, Ulmacege by 4, Celtidese by 2, Artocarpese by 2, Sali- 

 cinese by 2, Nyctaginese by 1, Monimiaceae by 1, Santalaceae by 4, 

 Daphnoidese by 2, Proteacese by 21, Laurineae by 18, and Morese by 

 19 species. Most of the species of the last two families present a 

 tropical aspect. [Count M.]
