The most favourable conditions occur in the so-called 

 vine scrubs. They are found in those portions where there 

 is sufficient moisture in the soil and sufficient rainfall. 

 In the North of Queensland, and especially in the coastal 

 region, the conditions for vine-scrubs are much more fav- 

 ourable than in other parts of Queensland, and they extend 

 over larger areas on different soils. They prefer, of course, 

 always a rich, deep soil, especially alluvial and basaltic, 

 but in those portions where the rainfall reaches a very high 

 range, we find them often on a very poor, almost innutri- 

 tions soil, as on Bellenden Ker or Bartle Frere, on a poor 

 granitic soil. 



Where the conditions are less suitable, the vine-scrubs 

 are restricted to narrow belts along the creeks and rivers. 

 These so-called " gallery vine-scrubs " are often found far 

 in the dry ojoen-forest country, which is usually unable to 

 bear this plant-association, requiring better soil and especi- 

 ally much more moisture, both in the soil and in the air. 



In the Southern part of Queensland the vine-scrubs 

 are usually only on good nutritious soil or near watercourses. 

 The largest area of vine -scrubs is found in the Gynipie 

 district (Eumundi, Yandina, etc.), but they are besides 

 this nearly everywhere on the basaltic mountains as far as 

 the Macpherson Range, the border of New South Wales. 

 Here we usually find that the distribution of vine-scrubs 

 coincides with the distribution of basalt. Sometimes the 

 scrubs extend from the basaltic plateaux along the creeks 

 down into the open forest country. In some places, where 

 the basaltic strata are too thin or the moisture insufficient, 

 we find forest instead of scrub. On the rich alluvial soil 

 along the creeks and rivers are also often narrow belts of 

 vine-scrubs. But most of them (at least in Southern Queens- 

 land) have disappeared, as they occupied the best agricul- 

 tural country, and have been cut down. 



In the far North of Queensland (as Cape York Penin- 

 sula), there are no vine-scrubs extending over big areas, 

 but notwithstanding there are along the creeks and rivers 

 splendid vine-scrubs, some of them very little known,. 

 but possessing a rich beautiful flora with many relations to
