Section Dumaria 
Section diagnosed as follows: oil glands in pith (sometimes sparse or absent in series 
lncrassatae)-, oil glands absent from bark; outer calyptra shed early; filaments inflexed; 
anthers dorsifixed, versatile, cuneate (shorter and more cuboid in series Merrickinnne, 
Leptocalyces and Deflexae), apically truncate, regularly radially arranged and apically 
packed against nectary disc, dehiscing by parallel slits; cotyledons rounded or 
shallowly obreniform; ovules in 4 rows (4-8 in series lncrassatae). 
All species included here are part of section Dumaria, itself a component of the large 
subgenus Symphyomyrtus (Pryor & Johnson 1971, Brooker 2000). This section is 
substantially Western Australian in distribution. The section is characterised by the 
regularly inflexed filaments with cuneate anthers that are regularly closely packed 
with their apices appressed to the nectary disc in unopened buds. The group is 
otherwise highly diverse, and has so far not been clearly demonstrated to be 
monophyletic. A number of distinctive and clearly defined series are recognisable, 
however, within the section Dumaria (Table 1). Series lncrassatae, Torquatae, Leptocalyces 
and Obtusiflorae are discussed separately below.

Series lncrassatae 
Treated as Series Tetrapterae by Blakely (1934: 73) and by Chippendale (1988), but with 
the inclusion of E. pimpiniana Maiden. The latter was excluded from this series by 
Brooke*- and Kleinig (1990), a view with which we concur. Brooker (2000) separated 
the E. tetraptera group into a separate series on the basis of autapomorphic novelties, 
ignoring informative grouping characters that clearly place it with the taxa here 
included in the series. 
Series distinguished as follows: oil glands usually present in pith, sometimes sparse or 
absent; juvenile leaves disjunct, petiolate; anthers angular or somewhat rounded; 
ovules in varying numbers of rows depending on species; seeds dark brown or black,
