Telopea 8(4): 2000 
recognising 15 species in series Albne. This included four recently described species 
(post Pryor & Johnson), and excluded £. urophylla. Other red gum series also followed 
Pryor and Johnson. Brooker and Slee (1994) departed from this arrangement, 
separating the E. brevifolia E MuelL group as a separate series Brevifoliae on the basis of 
autapomorphic seed coat characters. Brooker (2000) presents another approach to the 
red gum group, dividing it into three sections with no further comment on possible 
relationships and placing £. michaeliam in a fourth section. 
We now recognise that four series are discernible (Table 4), but would still regard them 
as allied and falling within section Exsertaria as diagnosed above (excluding 
£. michaeliam). A total of about 48 species make up the section, with 20 species in the 
two series Albae and Brevifoliae. Most species in these two series occur in areas that 
have until recently been poorly collected, and confusion has surrounded species 
determination and nomenclature. The Eucalyptus alba group (subseries Albosae) 
presents a number of taxonomic problems in Indonesia, Timor and Papua New 
Guinea, and will be discussed elsewhere.
