Phenetic analyses ofHomoranthus(Myrtaceae: Chamelaucieae) on the basis of morphology

Homoranthus tricolor (Myrtaceae), a new species from south-eastern Queensland

“…It seems closest to the species which have conspicuous, persistent bracteoles and laciniate sepals, in particular H. coracinus, H. darwinioides, H. decasetus and H. porteri. These species are closely allied to each other in the phenetic analysis of Copeland et al (2007).…”

Molecular and morphological analyses support recognition ofProstanthera volucris(Lamiaceae), a new species from the Central Tablelands of New South Wales

“…All characters were weighted equally in each analysis with the Gower association metric, as it is suited to datasets that contain a combination of quantitative, binary, and qualitative characters (Sokal 1986). The unweighted pair-group method using arithmetic means (UPGMA) was used as a means for cluster analysis as it is considered to accurately represent real distances between individuals in taxonomic datasets (Chappill & Ladiges 1992;Copeland et al 2007). Semi-strong hybrid multidimensional scaling (SSH-MDS) was used for ordination analyses as it has been shown to accurately reflect phenetic patterns (Minchin 1987) and has frequently been used in recent morphological phenetic studies, including studies of Prostanthera (Plunkett et al 2009;Conn et al 2013;Bean 2014;de Salas & Schmidt-Lebuhn 2018).…”

A morphometric analysis of Struthanthus phillyreoides and S. dichotrianthus (Loranthaceae) suggests these represent one single variable species1,2

“…Multidimensional scaling was chosen, as this technique is based on nonmetric relationship and it has been shown to be effective in representing phenetic patterns, (Belbin 1988, Faith et al 1987, Crisp 1991, Duretto and Ladiges 1997, Wills et al 2000, Copeland et al 2007, Maynard 2008. The program's default settings were used and combinations of two dimensional plots were generated from the data analysis.…”
