“…The generic analytic treatment in Ornithogaloideae sensu Martínez‐Azorín et al (2011) has been broadly subscribed to (Garbari et al, 2003, 2007; Johnson et al, 2012; Martínez‐Azorín & Crespo, 2012; Peruzzi et al, 2012; Pfosser et al, 2012; Ali et al, 2013; Martínez‐Azorín et al, 2013a, 2013b, 2014, 2015a, 2015c; Mulholland et al, 2013; Brudermann et al, 2019; Riahi Rad et al, 2019; Heidarian et al, 2020; Bogdanovic et al, 2021). Nonetheless, the alternative system for a broad Ornithogalum and Albuca (as proposed by Manning et al, 2009) has to date been adopted by the influential “The Plant List” or “World Checklist of Selected Plant Families” (WCSP, 2022).…”

The taxonomy and systematics of Urgineoideae (Hyacinthaceae) have been controversial in recent decades, with contrasting taxonomic treatments proposed based on preliminary and partial studies that have focused on morphology and/or solely plastid DNA sequence data. Some authors have recognized only two genera, with a very broadly conceived Drimia, while others have accepted several genera that, although better defined morphologically, were doubtfully monophyletic. Here, we present phylogenetic analyses involving four plastid DNA regions (trnL intron, trnL-F spacer, matK, and the trnCGCA-ycf6 intergenic region), a nuclear region (Agt1), and a selection of 40 morphological characters. Our study covers 293 samples and ca. 160 species of Urgineoideae (ca. 80% of its global diversity). Bayesian inference, maximum likelihood, and maximum parsimony analyses were performed to derive the phylogenetic patterns. The combination of data yielded phylogenetic trees with 31 welldefined clades or lineages, most corresponding to previously described genera, although some have required description or revised circumscription. As with other monocot families, a considerable degree of homoplasy was observed in morphological characters, especially in those groups with unspecialized flowers; nonetheless, consistent syndromes of traditional and novel characters are shown to support clade recognition at genus rank. The forthcoming revised classification of Urgineoideae is outlined here.
