NATIVE FLORA OF TROPICAL QUEENSLAND. 447 



until the return of rainy weather in December or January, 

 and thus become established. 



The reason that many native plants have restricted 

 habitats is not only owing to their preference for certain 

 soils or to differences of rainfall in various localities, but 

 because it is often difficult for the seedlings to establish 

 themselves under fresh conditions, and many plants will 

 thrive in localities away from their natural home if safe- 

 guarded during their infancy. 



I wish to express my thanks to Mr. J. H. Maiden, f.l.s., 

 and Mr. E. Cheel, for assistance and corroboration in the 

 identification of a number of plants, to Miss K. Hillcoat of 

 Boomarra, Oloncurry, and Mr. H. O. Oullen formerly of 

 Geera, for supplementing my collection of specimens.
