The Phanerogamia of the Mitta Mitta Source Basin. 43 



Epackide^e (R. Brown). 



Styphelia collina (Labillardiere). — Common on the ridges 

 dividing the western affluents of the Mitta Mitta, par- 

 ticularly in granitic areas ; ascends to about 5000 feet. 



Styphelia Macrasi (F. v. M.) — Along the margins of the 

 Mitta Mitta River and Livingstone Creek ; ascends to 

 about 5000 feet on the tributaries of the former. At the 

 lower elevations this species attains a height of 10 feet ; 

 at higher places it becomes dwarfed, the branches get 

 more densely pubescent, and the leaves are then less 

 petiolated. 



Styphelia ericoides (Smith). — On the upland flats at heads 

 of the Livingstone Creek this species is very gregarious, 

 forming a low, diffuse, heathy shrub; while on the 

 porphyritic areas near Omeo Plains, from 3000 to 4000 

 feet elevations, it frequently attains a height of 3 feet, 

 forming an erect, although bushy, shrub. 



Styphelia juniperina (Sprengel). — This pretty shrub is most 

 abundant on the Dividing Range at the head of Living- 

 stone Creek ; in Silurian formation, at about 4000 feet 

 elevations, and is descending into the Livingstone 

 Creek valley, in mica-schist formation, to 2000 feet. 



Brachyloma daphnoides (Bentham). — Common on the 

 northern stony slopes of Mount Livingstone, particularly 

 in the neighbourhood of the auriferous belts of meta- 

 morphic schist, Dry Gully, Omeo, at elevations from 

 2000 to 4000 feet. 



Trochocarpa pumila (F. v. M.). — On the granitic ridges at 

 the junction of Cobungra and Big Rivers ; at elevations 

 of 3000 to 5000 feet. 



Epacris petrophila (J. Hooker). — This low shrub is only 

 met with at the higher elevations, not descending below 

 3000 feet. It is common on the upper sources of the 

 Mitta Mitta, toward Mount Latrobe and the Bogong 

 High Plains, at about 5000 feet elevations. 



Epacris paludosa (R. Brown). — In similar localities with E. 

 petrophila, but descending to 2000 feet elevations, as on 

 the granitic area near the junction of the Big and 

 Cobungra Rivers. 



Epacris heteronema (Labillardiere). — Along grassy gullies at 

 the sources of the Cobungra and Big Rivers ; in granitic, 

 metamorphic, and Silurian areas ; ascends to about 5000 

 feet, but becomes dwarfed and stunted at the higher 

 elevations.
