46 The Phanerogamic*, of the Mitta Mitta Source Basin. 



Bulbine bulbosa (Haworth). — This succulent annual is pro- 

 lific on the grassy ridges near Omeo, at elevations of 

 2000 to 3000 feet. 



Thysanotus tuberosus (R. Brown). — This handsome species 

 is very abundant on the Mount Leinster Creek, near the 

 Omeo Plains, on granite-porphyry formation, at an 

 elevation of about 3000 feet ; it is also to be met with 

 on the slopes of Day's Hill, near Omeo, at about 3500 

 feet, on intrusive quartz-porphyry formation. 



Csesia vittata (R. Brown). — On rolling pasture-hills of the 

 eastern watershed of the Livingstone Creek. This 

 species is prevalent at elevations of 2000 to 3000 feet, 

 in metamorphic-schist formation. 



Tricoryne elatior (B-. Brown). — On grassy edges of small 

 streams flowing into Livingstone Creek, at elevations 

 of 2000 feet ; more abundant on the limestone area of 

 Bindi, south of the Dividing Range. 



Stypandra glauca (R. Brown). — On grassy flats along the 

 Livingstone Creek (especially in tufts of Poa casspitosa) 

 this species is plentiful ; it ascends to 4000 feet. 



Xerotes longifolia (R. Brown). — On rocky slopes of the 

 eastern watershed of the Livingstone Creek, on mica- 

 schist formation, at elevations of about 3000 feet. 



Xanthorrhcea australis (Smith). — Not frequent in this 

 source-basin ; confined to the dry, stony slopes of the 

 Dividing Range, near Omeo, on argillaceo-mica-schist 

 formation, at elevations of about 3000 feet ; more 

 abundant on granitic areas south of the Dividing 

 Range. 



Typhace^ (A. L. cle Jussieu). 



Sparganium augustifolium (R. Brown). — Only known at 

 present from Lake Omeo and Morass Creeks ; at an 

 altitude of about 3000 feet above the sea-level. 



Fluviales (Yentenat). 



Potamogeton natans (Linne). — This species was seen by me 

 only in the waterhol.es of Wilson's Creek (eastern 

 affluent of Livingstone's Creek), at an altitude of about 

 2200 feet ; it is probable, however, that it is yet to be 

 met with at higher elevations within this source-basin. 



JuNCEiE (R. Brown). 



Luzula campestris (De Candolle). — Abundant almost all over 

 the area, up to 5000 feet, in damp situations.
