Cedrda austratis (Ceaar or Red Cedar), so widely known 

 tor its most valuable timber, occurs in Cedar Creek, and 

 several more ol tlie almost inaccessible tributaries oi the 

 Jvowmung. Tlie conditions wliich this species demands, in 

 order that it may produce its nnest growths, are slielter, mois- 

 ture, warmth, t.nd a soil wliicli does not contain a high per- 

 centage ot silica. Consequently it is tound on good land, 

 • and conhned to the coastal area in (Queensland and New 

 fcjouth Wales. The most southern Cedar tree known to me, is 

 at Tillowrie, about two miles south of Milton. The Cedar 

 played an important part in the development of early Aus- 

 tralia, for many a country settlement, both on the North 

 and South Coast, was formed by the hardy pioneers who 

 went forth to secure this valuable timber. 



Acacia Maidtni was noticed about 2^ miles west of the 

 Wollondilly bridge, and, in the absence of flowers, which are 

 arranged in spikes, may often be confused with .-I . irii2)lcxa. 

 It is a coastal species, occurring around Sydney, and at Mil- 

 ton is well known under the name of Sally. A young Sally 

 is a handsome and graceful-looking tree, but soon after 

 maturity it becomes infested with the galls of a small wasp, 

 which has been identified by W. W. Froggatt as Trichilu-
