“…Other populations of E. bridgesiana have been linked to novel species previously, but when placed into context across the entire distribution of this species, their differences are questionable. For example, E. saxicola J.T.Hunter, a species described in 2001 based on material from exposed outcrops on Mount Canobolas in the central west of NSW, was differentiated from E. bridgesiana by its smaller stature, smaller juvenile leaves and slight differences in buds and fruit (Hunter 2001). However, E. bridgesiana exhibits wide variation in these features across its range and therefore populations exhibiting such subtle differences are insufficiently differentiated, potentially explainable by prevailing environmental conditions at specific sites (NSW Threatened Species Scientific Committee 2012; Slee et al 2015).…”

The identity of a population of eucalypts from Howes Swamp Creek in the eastern part of Wollemi National Park in New South Wales has remained unresolved for over 35 years. Despite several workers inspecting both the site and the trees growing there over this period, little consensus has been achieved on its taxonomic status. Various suggestions have been made that the entity was a new species with affinities to Eucalyptus dalrympleana, E. viminalis or E. bridgesiana, and at one time the unpublished manuscript name E. ‘wollemiensis’ was used. Because of the perceived small population size and threats posed by wildfire and other factors, the entity phrase name E. sp. Howes Swamp Creek (M.Doherty 26) was listed as an endangered taxon in both Commonwealth and State threatened species legislation. Our investigations over the last few years, involving field, seedling, and herbarium studies, have determined the original reference specimen designated for the phrase name is E. bridgesiana, and that the population from which the specimen was gathered comprises a hybrid swarm of E. bridgesiana × E. viminalis. Both parent species are present at the site, although the former species is seemingly very rare there. We recommend that E. sp. Howes Swamp Creek be removed from threatened species legislation, and that the names E. sp. Howes Swamp Creek (M.Doherty 26) and E. ‘wollemiensis’ ms be considered nomenclatural synonyms of E. bridgesiana.

Diploid chromosome counts are reported for the first time for 23 species of Homoranthus (Myrtaceae) and published counts are confirmed for a further three species. H. wilhelmii (F.Muell.) Cheel was determined as having 2n = 14, which contrasts with an earlier report of n = 6 for the species. Dysploidy appears to be common within the genus, with diploid chromosome numbers of 2n = 14, 16, 18 and 20 being recorded. There was no evidence of recent polyploidy within Homoranthus nor of any infraspecific dysploidy. Chromosome numbers appear to be a useful taxonomic tool to confirm the distinctness of some morphologically similar taxa but may be of limited use in estimating phylogenetic relationships.
