Phylogenetic relationships of Coronidium, Xerochrysum and several neglected Australian species of “Helichrysum” (Asteraceae: Gnaphalieae)

Abstract

A molecular phylogeny of selected Australian native Gnaphalieae (Asteraceae) is inferred from nuclear ribosomal ETS and ITS and chloroplast matK-psbA, psbA-trnH and ycf6-psbM sequences to test the reciprocal monophyly of the genera Coronidium and Xerochrysum and to taxonomically place several species currently treated as part of Helichrysum. Ribosomal and chloroplast phylogenies are topologically incongruent, but the latter are poorly resolved and poorly supported. Ribosomal and total evidence data suggest that the C. scorpioides group makes Coronidium in its current circumscription polyphyletic. Even without this species group, remaining Coronidium is inferred to be paraphyletic to Xerochrysum. Helichrysum macranthum and H. milligani are shown to be part of Xerochrysum and formally transferred to that genus. A lectotype is designated for H. milliganii. Helichrysum leucopsideum is shown to be affiliated with C. adenophorum and C. waddelliae while H. rutidolepis is confirmed to be part of the C. scorpioides group. In contrast, the affiliations of H. calvertianum, H. oligochaetum and H. pumilum cannot currently be resolved with confidence.Supplementary Material Electronic Supplement (Figs.

Helichrysum italicum (Roth) G. Don Essential Oil from Serbia: Chemical Composition, Classification and Biological Activity—May It Be a Suitable New Crop for Serbia?

“…The genus HelichrysumMill. includes over 300 species out of which 25 are distributed in Europe and the Mediterranean, while the others are distributed in Africa and Madagascar, Australia, and New Zealand [1][2][3], and also in temperate regions of Asia, including in India, Iran, and Turkey [4][5][6]. Mediterranean species belong to the Stoechadina section [7], and H. italicum (Roth) G. Don (syn.…”

A revised subtribal classification of Gnaphalieae (Asteraceae)

“…(2014) in maintaining Pseudognaphalium (including Laphangium (Hilliard & B.LBurtt) Tzvelev), Achyrocline , and Anaphalis as currently circumscribed. Accordingly, the distribution given in Table 1 for Helichrysum is for the genus in its current paraphyletic state, but not including species that are not part of the HAP clade still to be transferred from Helichrysum to other genera, such as those from New Zealand (Ward & al., 2009), Australia (Schmidt‐Lebuhn & al., 2015) and those from Hilliard's Group 10.…”

“…A phylogenomic analysis of ~1000 nuclear COS sequences including 19 Gnaphalieae genera also recovered these two clades (Mandel & al., 2019). Moreover, a number of recent studies have reinforced this pattern and increased the number of genera that can be unambiguously assigned to one of these two major clades (Galbany‐Casals & al., 2010, 2014; Montes‐Moreno & al., 2010; Bergh & al., 2011; Klaassen & Bergh, 2012; Schmidt‐Lebuhn & Constable, 2013; Freire & al., 2015; Schmidt‐Lebuhn & al., 2015; Nie & al., 2016; Bentley & al., 2017).…”

Daisies Down Under: Review of the state of taxonomy and phylogenetics of native Australian Asteraceae

“…and Odixia Orchard are epappose Cassinia and Ozothamnus, respectively, and Cassinia is Ozothamnus with receptacle scales. Of the three species groups of Coronidium, two are paraphyletic to Xerochr ysum, and the third is unrelated (Schmidt-Lebuhn et al, 2015). Comprehensive taxonomic revisions and phylogenetic analyses of the two genera have recently been completed (Tim Collins, ms. in prep.…”
