Ces considerations preliminaires sur la flore du Jura lacustre, qui 

 forment l'introduction de l'ouvrage, sont suivies des monographies 

 botaniques des 74 lacs jurassiens. Pour chacun, d'eux, apres l'indication 

 des principales donnees geographiques et limnologiques, l'auteur etudie 

 la flore macrophyte avec les plus grands details, en insistant sur les 

 zones de Vegetation, les particularites locales, les plantes caracteristi- 

 ques etc. De nombreux croquis, cartes, plans et coupes, et des listes 

 bibliographiques tres completes dresses specialement pour chaque lac, 

 accompagnent ces descriptions. J. Offner. 



Maiden, J. H., The Tree-line in the Australian Alps. 



(Vict. Nat. p. 84. 1904.) 



The trees forming the tree-line on M t. Koscinsko are Eucalyptus 

 coriacea (pauciflora). They are abundant on the Monaro plains, and can 

 be traced all up the above-named mountain, gradually diminishing in 

 height until (at 6, 500 ft. above sea-level) they abruptly cease, forming 

 a narrow strip of mallee-like growth about 20 ft. high. This growth 

 fringes the edge of the escarpment and extends for a considerable dis- 

 tance at the same level. There is no abrupt transition in tree growth, 

 and it is proper, in the authors opinion, to use the term „tree-line" in 

 the sense in which he has used it. This line is much lower on the 

 Victorian side, which is probably accounted for by its southern aspect.
