Labiatse. The almost exclusive occupation of vast 

 littoral tracts of Gippsland, and some of the adjoining 

 islands, by the dwarf Xanthorrhcea minor, is remark- 

 able. Mistletoes do not extend to Tasmania, though 

 over every other part of Australia ; neither the Nar- 

 doo (Marsilea quadrifolia), of melancholic celebrity, 

 though to be found in every part of the continent, and 

 abounding in innumerable varieties throughout the 

 depressed parts of the interior. Equisetacese occur 

 nowhere. The total of the species to be admitted as 

 well-defined, and hitherto known, from all parts of 

 Australia, approaches (with exclusion of microscopic 

 fungi) to ten thousand. 



It has been deemed of suflSlcient importance to ap- 

 pend to this brief memoir an index of all the trees 

 hitherto discovered in any part of Australia,* Such 

 statistics lead to reflection and comparison. They also 

 bring more prominently before the contemplative 

 mind the real access which in any branch of special 

 knowledge may have been obtained. In this instance 

 it is the only table with which this document has been 

 burdened, though ■ kindred lists might have readily 

 been elaborated. Nor would this imperfect sketch of 

 Australian vegetation have been extended to any de- 

 tailed enumerations whatever did not the trees im- 

 press on the vegetation of each country its most dis- 

 tinctive feature, and had we not learned how great a 

 treasure each land possesses in its timber— whether 

 as raw product to artisans or as objects of therapeutic 

 application, whether as material for the products of 

 manifold factories or as the source of educts in the 

 chemical laboratory ; whether as the means of afford- 

 ing employment to the workman, or even as the me-
