6 Phanerogamia of the Mitta Mitta Source Basin 



No. 7 — Pittospoee^: (R. Br.). 

 Genera — Pittosporum and Bursaria. 



1. P. bicolor (Banks). — A charming species, with hand- 

 some glossy sap-green foliage; bi-valved fruit; 

 shadedgullies ; along Dividing Range; Silurian soils ; 

 4000 feet ; wood useful for ornamental purposes. 



1. B. spinosa (Cav.). — Sparsely distributed within this 

 area, being confined to open rocky spurs of argil- 

 laceous schist ; at junction of Livingstone Creek 

 and Mitta Mitta River ; 1700 feet. At Tongio, in 

 valley of Tambo River; 1500 feet; it is abundant 

 in granitic soils ; and at Bindi, Middle Devonian 

 limestone formation in same valley, it attains a 

 height of 20 feet, with trunk 10 inches in diameter. 

 It does not appear to ascend anywhere in the Omeo 

 district above 4000 feet. It is locally known as 

 kangaroo thorn. Crude potash, crude tar, and acetic 

 acid have been obtained from its wood, according 

 to Mr. Guilfoyle curator of the Botanic Gardens. 

 I have also found the charcoal extremely useful 

 for blow-pipe work. 



No. 8 — Droserace^e (Salisb.). 



Genus — Drosera. 



D. Arcturi (F. v. M.). — The only species I have met with 

 of this interesting order is confined to the High 

 Plains, near Mount Cope, 6015 feet, on Silurian 

 soils and basaltic detritus; the glandular hairs 

 margining the leaf render it easily distinguishable. 



No. 9 — Polygale^ (A. & L. de J.). 

 Genera — Polygala and Comesperma. 



1. P. sibirica (L.). — Sparsely distributed on the flats 

 near Hinnomunjie, Mitta Mitta River; 1700 feet; 

 metamorphic schists and alluvium. 



1. C. retusum. — Widely distributed within the area ; on 

 all paleozoic and basaltic soils up to 5000 feet. 



No. 10 — Rutace^: (A. L. de Jussieu). 



Genera — Correa, Zieria, Boronia, and Eriostemon (including 



Crowese).
