Grevillea parviflora, E. Brown. 



Along the margin o£ the streams forming the source 

 affluents of the Mitta Mitta River, on Metamorphic and 

 Silurian areas, it is an erect rather bushy shrub, which attains 

 a height of ten to twelve feet ; but at elevations of 4,000 feet 

 it becomes dwarfed. It extends easterly to the Genoa Eiver, 

 to the Illawarra and Blue Mountains in New South Wales ; 

 westerly to Portland, and South Australia at Kangaroo Island. 

 It would be interesting to note the difference between the 

 South Australian variety if found growing on the Tertiary 

 formation of Kangaroo Island and our alpine form common to 

 the older Palaeozoic and Metamorphic schists. 



Grevillea australis, E. Brown. 

 This much-branched shrub is found growing on the Silurian 

 areas in the Mitchell Eiver source basin south of the Dividing 

 Eange, at elevations of 5,000 feet. Near Mount Selwyn it be- 

 comes dwarfed and decumbent, clinging to the rocks. It has 

 been found at Mount Wellington and the sources of the Yarra 

 Eiver, and southerly in Tasmania, at elevations of 4,000 feet. 



Grevillea ramosissima, Meissner. 



This interesting species is apparently confined in Victoria to 

 two stations — the Upper Hume Eiver on Silurian formation 

 {Baron Mueller), and at the junction of Livingstone Creek 

 with the Mitta Mitta Eiver on Metamorphic schists. At the 

 latter station it attains a height of three to six feet, and its 

 altitudinal limit is 3,000 feet. It appears to be rapidly imder- 

 going extinction. It is more plentiful in New South Wales, 

 extending to the Goulburn Eiver, Macquarie Eiver, and other 

 localities. 



Hakea eriantha, E. Brown. 

 An erect arborescent shrub, the fruits of which are locally 

 known as hickory nuts ; is most abundant on the Silurian areas 

 of the Tambo and Dargo Eivers, south of the Dividing Eange, 

 at elevations of from 2,000 to 4,000 feet ; and on the gneissic 

 schists of the Mitta Mitta basin, at elevations of 3,000 feet. 

 It extends easterly to the Genoa Eiver, and to the Hastings 

 Eiver and New England, New South Wales. 



Hakea rugosa, E. Brown. 

 A prostrate species ; confined, as far as known, in A'ictoria 

 to the Upper Palaeozoic formation at the head of the Macalister 

 Eiver, south of Dividing Eange. It is widely distributed in 

 South Australia.
