32 The Phanerogamic, of the Mitta Mitta Source Basin. 



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



Comesperma volubile (Labillardiere). — This twining species 

 is more common on the coast regions of the Mitchell 

 River basin; apparently rare on the Mitta Mitta 

 affluents. A few plants are met with on the Dividing 

 Range, near Mount Phipps, in scrubby localities of 

 Silurian formation, at elevations of 3000 to 4000 feet. 



Comesperma ericinum (De Candolle). — Very abundant on 

 the auriferous areas; Dry Gully near Omeo, particularly 

 on stony northern slopes, near junction of intrusive 

 granite and metamorphic schists ; at 2000 to 3000 feet 

 elevations. 



Tremandrke (R. Brown). 



Tetratheca ciliata (Lindley). — Sparsely distributed on sandy 

 soils near the head of Livingstone Creek, at 3000 feet 

 elevations ; more abundant in the Wentworth Valley ; 

 its bright carmine- coloured petals render it easily dis- 

 tinguishable amid its sombre-coloured foliage. It is 

 extremely sensitive to moisture, closing its petals (like 

 some species of Helipterum and Helichrysum) on damp 

 or rainy days, and opening again with the sunshine. 



Rutaceje (A. L. de Jussieu). 



Zieria Smithii (Andrews). — See pt. 1, p. 7. 



Boronia Algida (F. v. M.). — This shrubby species is abundant 

 at high elevations — for instance, on the sources of Big 

 River, and on the rocky, rolling ridges towards Bogong 

 High Plains at 5000 to 6000 feet elevations ; also near 

 the summit of Mount Hotham. It appears to be 

 governed in its distribution more by climatic conditions 

 than by character of soil. — See pt. 1, p. 7. 



Eriostemon Crowei (F. v. M.). — Var. Exalata. — On granitic 

 areas, near the junction of the Cobungra and Big Rivers; 

 at about 3000 feet elevation. — See pt. 1, p. 7. 



Eriostemon phylicifolius (F.-v. M.). — This somewhat dwarfed 

 species is found growing on the quartz-porphyry forma- 

 tion near Mount Sisters at elevations of about 3000 

 feet, and on Dividing Range toward Mount Tambo. 



Eriostemon ozothamnoides (F. v. M.). — On the river gravels 

 at the junction of Livingstone Creek and the Mitta 

 Mitta River, thence ascending along the margins of the
