858 OCCURRENCE OF A LIMESTONE-FLORA AT GROSE VALE.-

 Total 57 families, 130 genera, and 156 species. It is remark- 

 able how few genera are represented by more than one species. 



There is no doubt that, even up to recent years, this flora 

 covered an area much larger than it does to-day. Many roadside 

 plants, both native and introduced, have established themselves.. 

 Clearing is still going on. The conditions for luxuriant growth^ 

 are no longer so favourable, and in a few years this interesting, 

 patch of vegetation will probably disappear.
