Sub-order No. 2 — Mimose^:. 

 Genus — Acacia. 



1. A. myrtifolia (Willd). — Flourishes on the northern 



slopes of Mount Livingstone, in the neighbourhood 

 of granite dykes ; along western or southern water- 

 shed of Dry Gully; auriferous .country ; 3000 feet. 



2. A. melauoxylon (R. Br.), locally called " lightwood." — 



Is dispersed among eucalyptus in eastern water- 

 shed of Livingstone Creek ; ascends to 4000 feet ; on 

 metamorphic soils. 



3. A. discolor (Willd). — On Dividing Range, at head of 



Livingstone Creek ; 4000 feet ; granitic soils ; it is 

 sparsely distributed. On Wentworth River it is 

 more gregarious, forming dense underscrub on 

 Silurian soils. 



4. A. decurrens (Willd). — Is moderately abundant 



within the area along the upper flat courses of 

 gullies ; metamorphic soils ; south of Dividing 

 Range it is abundant. 



5. A. pycantha, " golden wattle." — Only occasionally to 



be met with in the area, on Silurian soils ; it is 

 prolific on ranges south of Dividing Range ; its 

 gum is very transparent. 



6. A. vomeriformis. — This peculiar shrub is abundant 



on the coarse sandy soils disintegrated from 

 quartz conglomerate in upper courses of Wentworth 

 River at elevations of 3000 feet. On Dry Gully 

 watershed, near Omeo, it is also to be met with 

 on gneissose schists. Another species, similar 

 in appearance to A. vomeriformis, is also to be 

 met with in same habitat. 



7. A. silicuformis (A. C). — Is abundant on the gravels- 



along bed of Livingstone Creek ; 2000 feet. 



8. A. alpini (F. v. M.). — Is met with on all elevations above 



3000 feet up to 5000 feet, principally on altered 

 Silurian soils. 



9. A. verticillata (Willd). — In similar habitats to A. 



vomerformis, particularly in Wentworth River 

 watershed, at elevations of 3000 feet. 



No. 20— Rosacea (A. L. de J.).
