and their Habitats. 13 



1. C. salignus, var. Siebierii (D. C). — On the Paw and 

 Precipice Plains; 4000 feet; basaltic formation; 

 more abundant along source runnels ; intersecting 

 the higher plateaux of Dargo High Plains, south 

 of Dividing Range ; 5000 feet. 



Eucalyptus. 



1. Genus E. amygdalina, "white gum," is the most 



prevalent species ; distributed all over the area 

 up to 5000 feet, where it gives place to C. alpini 

 — our Alpine species, locally called snow gums. 



2. E. obliqua " stringy bark." — Sparsely distributed on 



granitic and coarse argillaceous schist formation, 

 on the northern sunny slopes of the lower ridges 

 and along the crest of the main Dividing Range. 



3. F. melliodora, " honey eucalypt, or box." — Is hardly 



represented north of the Dividing Range ; along 

 the valley of the Tambo it is the principal species, 

 remarkable for its ash-grey foliage, the durability 

 and hardness of its timber, and its excellent 

 qualities as fuel. It flourishes in hard granitic 

 and gneissic soils in this watershed. 



4. E. globulus, "blue gum." — Attains a great height 



amid the moist southern slopes along the Dividing 

 Range, although not abundant within the area. 

 I have noted trees in the moist gullies, starting 

 from the Tambo Gully, 320 feet high, with leaves 

 lanceolar falcate, fully 2 feet long. 



5. E. fissilis, " messmate," is moderately distributed 



along with 



6. E. coriacea, on lower heathy spurs, near the 



Dividing Range. 



7. E. viminalis, " manna gum," is confined to the flats 



along the Livingstone Creek. 



8. E. stuartina, is common towards the Omeo Plains, 



while close to Omeo a rough-barked, black- 

 stemmed, thick-foliaged species, known as " Black 

 Sally," gives character to the landscape. 



9. E. rostrata, "red gum," and 10, C. sicleroxylun, "iron 



bark," are absent from this source basin, unless on 

 the eastern affluents, at lower elevations, as along 

 the Gibbo River. 

 11. E. pauciflora and 12, E. gunnii, are shrubby Alpine 

 species, which Baron Mueller has been good enough
