also has been annotated by Mueller as both A. ixiophylla and as A. glutinosa. Bentham (1864) 
synonymized A glutinosa under A. ixiophylla, explaining he could see no real differences between 
the two, one from the west, the other from the cast. Certainly the flowering material on the type 
sheets is not A. ixiophylla nor does it have anything to do with A. montana as suggested by Maiden 
(1916) in his analysis of the confusion surrounding A. glutinosa, A. ixiophylla, A. montana and 
A.fuliginea. 
Assuming that the flowers and fruits comprising the type of A. glutinosa represent the same 
taxon, we are at a loss to suggest what it might be. The fruits could be those of 4. verricula, 
although the seeds of this species arc smaller than those in the packets, and its phyllodes shorter, 
differently shaped and with totally different venation from the type of A. glutinosa. The 
phyllode-nerves of the A. glutinosa Lypc are numerous, immersed and rarely with anastomoses, 
while A. verricula phyllodes have a fine, regular reticulum of secondary nerves. 
In view of well-documented instances of Mueller’s rather lax curatorial practices, we consider 
seriously the possibility that the MEL sheets bear material of two different taxa, the Maxwell seed 
collection from Western Australia (possibly A. verricula or close relative) and the cultivated 
flowering specimens from the botanical garden, representing a species we are unable to identify. 
Because of the uncertainties involved, we are not prepared to lectotypify the name and conclude 
that A. glutinosa must be considered a nomen dubium. 
Conservation status. Not considered as cither rare or endangered. 
Etymology. A. verricula is so-named in allusion to the net-like appearance of the secondary 
nervature of the phyllodes.
