On the north-western side of the range, where the plants are 

 -exposed to drying winds, the brush vegetation extends but a few 

 yards down the slope. But on the east it goes right down to the 

 bottom, and here a splendid soil, partly Ijasaltic in origin and 

 partly vegetable soil, is found. Here earthworms of large 

 size flourish. In such situations there is little undergrowth but 

 ferns; no grasses occur at all. The same thing occurs in the 

 brush forests of Illawarra, and when the land is cleared it has 

 to be sown with English grasses for dairy farming. 



One point worth noticing is the much greater diversity of 

 flowering plants on the sandstone. 



I have not given the numbers on either formation, as no record 

 was kept in many instances. On the sandstone the plants are 

 seldom restricted to one small area, while it is very much the case 

 on the basalt, some plants being found only in one small patch of 

 but a few square yards in extent, Probably as more attention 

 is paid to collecting in all parts of the volcanic area some 

 additional plants will be found. 



A comparison of the floras of the five peaks mentioned would 

 be of interest, but sufiicient data are not at present available. 

 Allan Cunningham (1) and Dr. Woolls (8) have recorded their 

 experiences at Tomah, but in neither case was a census of the 

 flora the object in view. 



The following list has been compiled from Dr. Woolls' paper 

 (9) and a manuscript list he gave me, from plants collected by 

 Messrs. J. H. Maiden, J. D. Cox, J. Gregson, P. N. Trebeck (5) 

 and myself. Mr. Gregson's plants have been identified by Mr. 

 Maiden, and Mr. Cox's and my own by Dr. Woolls and Mr. 

 Maiden : — 



Note. —The letter B after the name of a plant denote that it grows on 

 the basaltic area ; S on the sandstone ; and B & S on both. Where no 

 hiitial is appended, no record has been kept.
