436 BOTANICAL GEOGRAPHY. 



On the 16th of June the author collected 300 species of plants on a 

 mountain-ridge of the Karst, only 3410' in height, to the south of the Fium- 

 mean road ; they are enumerated in the order of their occurrence in this 

 luxuriously-printed work. In the map which is appended, the following 

 regions of the coast-country of Illyria, in the direction from the Adriatic Sea 

 to the coast of Terglou, are distinguished, but how the altitudes were deter- 

 mined is not stated : 1, 0' 500' ; region of Olives. 2, 2000' ; oak-region 

 (with regard to which it is incorrect to state that the region of the species 

 of the north of Europe is not different from that of the Mediterranean species). 

 3, 2000' 4800'; beech region. 4, 6500' ; pine region. 5, 8500'; region 

 of the alpine plants. 6, 9036' ; region of snow. The vegetation of the 

 Golaz mountains resolves itself into the oak forests (1500' 2000' : Quercus 

 Robur, pedunculate, Cerris, ^.n^pubescens}, beech forests (2000' 3410'), alpine 

 pastures, and the rocky formation. In addition to this main subdivision, 

 separate arrangements in groups are also mentioned, e. g. shrubs of Ornus 

 in the lower, and of Corylus Avettana in the upper part of the oak-region, 

 herbaceous meadows of Cyiisus and Genista, &c, 



Wierzbicki has published a Catalogue of the Plants 

 found in the Banat (Ratisbon Flora, 1845, pp. 321-25), 

 subsequent to the appearance of the most recent work on 

 the flora of this province (Rochel's Travels in the Banat, 

 1838); also, Prof. Fuss, of Hermannstadt, a list of 319 

 plants of Siebenburg, with their localities (Archiv des 

 Vereins fur Siebenburg. Landeskunde, (Bd. 2, Hft. 3). 



O. Heer's memoir upon the Upper Limits of Animal 

 and Vegetable Life in the Swiss Alps (Zurich, 1845, 4to), 

 is more important in a geological than a botanical point of 

 view, on account of the descriptions and illustrations of 

 new insects belonging to the snow-region contained in it ; 

 however, it also contains some valuable observations on 

 the forms of plants, which, under certain conditions, 

 vegetate above the snow limit (8500'). 



Lichens extend far above the Phanerogamia and Mosses ; they exist even 

 on the summit of Mont Blanc. The highest of the Phanerogamia was 

 Androsace glacialis (pennina Gaud.), and occurred at 10,700' on Pic Linard ; 

 and from this altitude down to 10,000', the following were found in succes- 

 sion on different glaciers, i. e. on account of the position or inclination of 

 the surfaces free from snow on the Rhetian Alps : Oentiana bavarica, 

 var. imbricata, Silene acaulis, Chrysanthemum alpinum, Ranunculus glacialis, 

 Cerastium latifolium, var. glaciale, Saxifraga oppositifolia and bryoides, Cher-
