NATIVE FLORA OF TROPICAL QUEENSLAND. 401 



April, and this latter condition applies to practically the 

 whole of northern Queensland, so that by the month of 

 August the country away form the watercourses is getting 

 decidedly dry. Botanists who have had experience in 

 collecting in this class of country well know that the season 

 for the flowering and fruiting of a plant is short. The 

 result is that the visitor often finds a difficulty in identify- 

 ing plants owing to the absence of both flowers and fruits. 

 It will also be understood that small plants, including 

 grasses, are likely to be overlooked in the dry season.
