Abstract 
Cowan, R.S. & B.R. Maslin. Acacia Miscellany — 1. Some oligoneurous species of Acacia (Leguminosae: 
Mimosoideae; Section Plurinerves) from Western Australia. Nuylsia7(2): 183-199 (1990). A key is presented to seven new 
Western Australian species of plurtncrved wattles (A. awesloniana, A. cassicula, A. consobrina, A. lanei, A. lobulala, 
A. spongolitica and A. verricula), one new variety (A. flavipila var. ovalis ) and to several other related and previously 
described species. The need for a new name (A. lanuginophylla) for A. lanuginosa C. Gardner is discussed and the identity 
of A. glulinosa F. Muell. is considered. 
Introduction 
The taxa of the Acacia verricula and A. flavipila alliances, some of which are treated herein, 
have few characteristics in common other than that many have resinous vegetative and/or flower 
parts and the flower-heads are borne in axillary racemes, although these are often very short. In 
addition, both groups of taxa have oligoneurous phyllode-ncrvaturc (lor definition, sec Maslin & 
Pedley (1988). Pedley (1987) used the term oligoneurous in a much more restricted sense than we 
are: we use it to refer informally to taxa characterized by phyllodes having only a few, distant 
longitudinal nerves with or without anastomosing minor nerves between them). These alliances are 
informal groupings, intended merely as mnemonic devices for ourselves and for potential users; 
however, the species in each grouping, or alliance, are probably genuinely related to one another. 
They are all treated in the following key but descriptions are provided only for the new taxa; these 
are numbered in the key and arranged alphabetically in the text. 
This is the first of a series of papers, by one or more of the "Wattle Team" at PERTH; this and 
those following arc intended to validate the names of new taxa and to present extended notes, new 
names, new combinations and redescriptions of previously described taxa, prior to the synoptic 
treatment of them in the "Flora of Australia". Measurements in the following descriptions are taken 
from dry material unless otherwise noted.
