The jPhanerogamia of the Mitta Mitta Source Basin. 33 



Big River, Cobungra River and Bundara River; on 

 granitic and argillaceous schist areas up to 5000 feet. 

 The plant is very much stunted at the higher elevations. 

 Eriostemon trachyphyllus (F. v. M.). — Common on Silurian 

 soils along crest of Dividing Range at heads of Living- 

 stone Creek ; 4000 feet elevation ; more abundant and 

 gregarious on the upper sources of Wentworth River, 

 there forming dense scrubs, 20 feet high, to the total 

 exclusion of other vegetation. 



Geraniace^e (A. L. de Jussieu). 



Geranium Carolinianum (Linne). — Abundant near Omeo 

 on the soft mica-schist areas ; up to 3000 feet. Baron 

 von Mueller thinks that the Australian plant might be 

 kept distinct as G. pilosum (Forster). 



Oxalis corniculata (Linne). — Common all over the lower 

 ridges of the eastern watershed of the Livingstone 

 Creek; up to 3000 feet. 



Euphorbiace,e (A. L. de Jussieu). 



Poranthera microphylla (Brongniart). — All over the area 

 this widely-spread species is abundant. On the mica- 

 schist formation near Omeo it attains a height of only 

 3 or 4 inches ; but on the Silurian ranges near Grant 

 it frequently grows to a height of 10 to 12 inches. 



Micrantheum hexandrum (J. Hooker). — A robust shrub 10 

 to 12 feet high; at the junction of Livingstone Creek 

 and Mitta Mitta River. 



Bertya Cuoninghami (Planchon). — In similar locality to 

 M. hexandrum, and on lower levels along Mitta Mitta 

 River. 



Casuarine^ (Mirbel). 



Casuarina quadrivalvis (Labillardiere) . — This species, so 

 common in littoral regions in the upland, is here met 

 with in the granite area of the Mount Sisters, near 

 Omeo Plains, at 3000 feet elevation. 



Sapindacile (A. L. de Jussieu); 



Dodonaea viscosa (Linne). — The var. attenuata is common 

 .on the Mitta Mitta at Hinnomunjie Flat on tertiary 

 gravels ; the leaves have a sour and bitter taste.
