Title: | New chromosome numbers in 'Homoranthus' (Myrtaceae: Chamelaucieae) and notes on their taxonomic utility | Contributor(s): | Copeland, Lachlan (author); Bruhl, Jeremy James (author) ; Craven, Lyn A (author); Brubaker, Curt L (author) | Publication Date: | 2008 | DOI: | 10.1071/SB08036 | Handle Link: | https://hdl.handle.net/1959.11/2753 | Abstract: | 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. | Publication Type: | Journal Article | Source of Publication: | Australian Systematic Botany, 21(6), p. 443-447 | Publisher: | CSIRO Publishing | Place of Publication: | Australia | ISSN: | 1446-5701 1030-1887 |
