In Acacia we have the old troixble of non-matching, 

 or doubtful matching, of flowers and fruits. This difficulty 

 is often referred to in the Flora Australiensis, and with 

 collectors at any time it is a real one because of the com- 

 parative scarcity of permanent residents in the tropics, 

 and of the distinct interval that often occurs between 

 flowering and fruiting time in this genus. The flowering 

 specimens, being the more attractive and conspicuous, are 

 by far the more abundant in herbaria. Correspondents 

 are asked for fruiting specimens, but while the task may be 

 difficult enough if the pods are in situ, it is sometimes 

 immeasurably greater if they are detached.

Bentham, George. " Notes on Miraosse," with a 

 synopsis of species (Tribe iii. Acaciae), in Hooker's London 

 Journal of Botany, i, 318-392, 494-523 (1842). In Latin. 

 This is valuable in that it describes a number of Queens- 

 land species collected by Allan Cunningham, Charles 

 Eraser, Ferdinand Bauer (Brown's colleague). Major 

 Mitchell. The species that interest us most in the present 

 enquiry are those collected by Allan Cunningham.

This primarily takes cognisance of the Acacias of what 

 is now the Northern Territory, collected by the author in 

 the Expedition under A. C. Gregory in 1856 from the Lower 

 Victoria River to the Gulf of Carpentaria. At the same time 

 Mueller includes some species from Queensland and other 

 parts of Australia. 



Of the localities given, I only knoAv three as stated to 

 occur in tropical Queensland. It has since been proved 

 that a number of species first recorded bj^ Mueller from the 

 Gulf of Carpentaria have since been found in Northern 

 Queensland, but it must be borne in mind that Mueller 

 collected on the Northern Territory side of the Gulf of 

 Carpentaria, and it is unscientific to record for a State 

 unless a specimen has been collected within the borders 

 of that 8tate.
