and (9) Mt. Kinderun, The plants listed in this paper were 

 collected from all the above volcanic foimations except Mt. 

 Kinderun and Green Hills, which I have not yet had an oppor- 

 tunity of visiting. 



The list of grasses is poor (only one species being identified) 

 because more time has been devoted to the collecting of other 

 species. 



On approaching one of the "Clears," one is at once struck by 

 the marked difference between the orowth of the veo'etation on 

 it and that on the adjacent sandstone country, and by the absence 

 on the volcanic soil of species growing in profusion on the sand- 

 stone, as well as by the comparative rarity of a certain species of 

 Eucalyptus on the sandstone which is always present on the 

 Clears, i.e., E. heytiiphloia, F.v.M. 



The "Clears" are covered with a dense growth of grass upon 

 which stock fatten rapidly. This dense growth of grass is absent 

 on the sandstone ridges, and not so plentiful on the flats, especially 

 those situated at a distance from the Clears. 



On the sandstone ridges the Eucalypts do not attain to the 

 same height or girth as the same species growing on the basalt, 

 or on the flats immediately adjacent to the basalt, and which 

 receives the decomposed volcanic matter from it. 



In a former paragraph I referred to the absence of certain 

 plants occurring on the Clears and Basalt Masses which are 

 common on the sandstone, and I think it would not be out of 

 place to mention the more important; for instance — Eucalypins 

 exiruia, Schauer., E. Rossi, Baker k, Smith, E. piperita, Sm., E. 

 punctata, DC, Angophora lanceolata, Cav., various species of 

 Melaleuca, Leptospermum, Backhousia, Dai-iesia, the various 

 Proteaceous plants, such as Hakea, kc. Several species of the 

 Natural Order Epacridea3, which flourish on the sandstone ranges, 

 disappear immediately the basalt is met with. Oxylobium trilo- 

 batum, F.v.M,, Gomjyholobium latijoliiun, Sm., and Eossicea 

 heterophylla. Vent, also are absent. 



It appears that Clears and Basalt Masses are factors for good 

 in an}^ district in which they occur, as is instanced in this district
