certainty out of the Northern Territory. It will probably be found in Queensland 

 (round the Gulf), but the Queensland specimens hitherto referred to this species are 

 not satisfactory.

AFFINITIES. 



1. With E. setosa Schauer. 



In the original description, Mueller stated that the affinity of E. aspera is with 

 E. setosa. 



The position of E. setosa is rather with the Corymbosse, at least so far as the 

 fruit is concerned. Mueller's original description of the fruit of i?. aspera as " somewhat 

 campanulate and ecostate, valves included," does not help us much without other data. 



Bentham's specimens " are not in good state," but he describes the fruit as 

 " ovoid-truncate, slightly contracted or straight at the orifice, 3 to 4 lines long, the rim 

 thin, the capsule deeply sunk." The fruits are the thin papery ones of the clavigera 

 group, and not the thick woody, coarse ones of the setosa group. 



2. With E. clavigera A. Cunn. 



In B. Fl. iii, 250, Bentham places E. aspera near E. grandijolia, clavigera, and 

 tesselaris, though in the Key (p. 198) he places it nearer to E. doratoxylon. 



E. aspera, from the testimony of the thin papery fruit alone, comes closest to the 

 E. clavigera group, as already indicated.
