114 REV. W. WOOLLS, PH.D., F.L.S., ON THE 



early part of the century only twelve species were recorded 

 by botanists, but now probably 150 Jiave been found in 

 different parts of Australia, and of these 100 may be 

 recognized in the figures of the Baron's Euccdiiptographia. 



Of Myoporina3 the same author records seventy-six species, 

 chiefly Australian, and two genera exclusively so (FhoUdia 

 and Ereinopldla). Here again the Baron has contributed to 

 a correct knowledge of Australian botany by his elegant 

 figures, seventy-four in number, including several species of 

 Eremophila Avhich are worthy of a place in any con- 

 servatory. 



Though not principally Australian, the species of Salso- 

 iaceee are highly important as furnishing forage plants to 

 sheep and cattle in dry seasons. Many of these the Baron 

 has also .figured with a view of aiding pastoralists and 

 graziers in the identification of species, and of ascertaining 

 liow far i\\Q prevalence of certain plants of the order may 

 enhance the value of runs. In the early days of the colony 

 Bauer's drawings were very useful in making known some 

 of the beauties of the Flora, but these have been far sur- 

 passed in number and extent by the figures published by the 

 Baron, including not only Eucalypts, Acacias, ]\Iyoporiuous 

 and Salsolaceous ])lants, but also many species of the Flora 

 generally which have economic or useful properties. The 

 extension of botanical knowledge has led to the discovery of 

 many plants remarkable not merely for ornamental pm-poses, 

 but for commercial and medicinal value. 



The various kinds of Australian timber are now much 

 better known in Europe than before the publication of the 

 Flora, for they can be identified by their scientific names. 

 Formerly some of the best woods were transmitted to 

 England with nothing attached to them but popular names, 

 Avhich, though understood in the districts from which they 

 Avere sent, were unintelligible to European purchasers. 



The two great orders Leguminosaj and ]\Iyrtacea3 furnish 

 specimens of wood not to be surpassed in strength and 

 durability. Castaiionperrnion auMrale (A. Cunn.) is remarkable 

 for the large quantity of dark-coloured heartwood that it 

 produces, and BarMya Lyringifolia (Mueller) for its very 

 tough grain; Avhilst the genus Acacia affords numerous 

 species Avhich can Ije utilised for the beauty and hardness of 

 their wood, the tanning properties of their bark ;ind the 

 copiousness of their gums. 



Amongst the Myrtaceai the vast genus Eucahiptus is dis-
