48 The Phanerogamia of the Mitta Mitta Source Basin. 



Scripus polystachyus (F. v. M.). — On Morass Creek, near Lake 

 Omeo, and on the Mitta Mitta River, at elevations from 

 1000 to 3000 feet 



Schcemis Brownii (J. Hooker). — On damp soils near Omeo. 



Lepidosperma concavum (R.Brown). — Common on the rocky, 

 exposed northern slopes of Mount Livingstone, near 

 Omeo, at elevations of about 3000 feet, on mica-schist 

 formation, and on the northern slopes of the Dividing 

 Range, east from Omeo, in argillaceo-schist formation, 

 at between 2000 and 4000 feet elevation. 



Lepidosperma lineare (R. Brown). — In similar localities to 

 L. concavum, and northerly toward Mount Leinster, on 

 granitic-porphyry formation, at elevations from 3000 to 

 4000 feet. 



Uncinia tenella (R. Brown). — In shaded gullies among fern- 

 trees on the Dividing Range, east from Omeo, in argil- 

 laceo-mica-schist formation, at elevations from 3000 to 

 4000 feet. 



Carex acicularis (Boott). — On the Paw Paw tableland, in 

 basaltic formation, at about 5000 feet, and on the heads 

 of the Cobungra River, near Mount William, in argil- 

 laceo-schist formation, at elevations of about 6000 feet. 

 This small species is abundant ; it does not appear to 

 descend within this source-basin below 4000 feet. 



Carex in versa (R. Brown). — Common along the sandy allu- 

 vial flats of Livingstone Creek; at elevations of 2000 to 

 4000 feet. 



Carex vulgaris (Fries). — On swampy flats and marshes along 

 Wilson's Creek, near Omeo, ascending the Dividing 

 Range to 4000 feet. 



Carex acuta (Linne). — On the heads of the Cobungra, Vic- 

 toria, and Big Rivers, at elevations from 3000 to 5000 

 feet. 



Carex Buxbaumii (Wahlenberg). — On the upland flats near 

 Mount Hotham and on the Bogong High Plains, at 

 elevations from 3000 to 5000 feet, and on the Living- 

 stone Creek and Omeo Plains, at about 3000 feet eleva- 

 tion. It appears to flourish best on rich basaltic soils in 

 marshy localities. Identified with numerous other 

 alpine plants already by Baron von Mueller, 1853-55. 



Carex breviculmis (R. Brown). — On the eastern watershed of 

 the Livingstone Creek, near Omeo, and on the Victoria 

 Plains, at elevations from 2000 to 4000 feet, in mica- 

 schist and metamorphic-granite areas.
