ON THE BOTANY OF RYL8T0NE AND THE 

 GOULBURN RIVER DISTRICTS. PART I. 



Bv R. T. Baker, F.L.S., Assistant Curator, Techxological 

 Museum, Sydney. 



The area of the colony treated of in this paper comprises the 

 eastern divisions of the Counties of Phillip and Roxburgh, — a 

 portion of New South Wales, which I believe has not previously 

 been explored botanically. 



The northern boundary of this area is the Goulburn River, 

 which rises on the eastern slope of the Dividing Range, a few 

 miles south-west of the town of Ulan, and flows easterly in a 

 tortuous course, eventually joining the Hunter River a little 

 south of Denman. It runs mostly through precipitous and moun- 

 tainous sandstone ridges, and consequently is subject to 

 inundations, — flood-marks being found at a considerable height 

 above its ordinary level. The country between the river and the 

 Dividing Range consists principally of mountain ranges, with 

 occasional patches of good soil, derived from the disintegration of 

 basalt from the volcanic outcro^is, approximating in area about 

 1000 sq. miles. It is sparsely populated, there being only about 

 half a dozen small Public Schools scattered throughout this large 

 area. Settlements are therefore few and far between, and conse- 

 quently much of the indigenous flora remains, so that it is a 

 splendid country for botanising. 



The eastern boundary is formed by Widdin Brook, a stream 

 which rises in Corricuddy Mountain and flows north into the Goul- 

 burn River, and the main Dividing Range as far south as Capertee. 



The western boundary is the Barrigan Ranges and a line drawn 

 from these south throuijh the town of Cudo-esono: to Ilford.
