关于Nomocharis Franchet（1889：113）属的地位的争议自Franchet（1889）承认以来一直在进行。最近的分子研究（Nishikawa et al. 1999，Hayashi & Kawano 2000，Nishikawa et al. 2001，Ronsted et al. 2005，Peruzzi et al. 2009）已经将Nomocharis解析为嵌套在百合属内（1753：302）。我们自己以前的研究结果（Gao et al. 2012，Gao et al. 2013 a，Gao et al. 2013 b），扩大了Nomocharis物种的采样，与其他人以前的研究结果一致。因此，承认Nomocharis将使百合并系。我们倾向于在这里承认一个单系百合属，尽管文献中有时提倡并系群（例如，Brummitt，2014; Escherdorfer & Barfuss，2014;乔治，2014; Horandl，2014; Stuessy & Horandl，2014; Stuessy等人，2014）。最近，我们提出Nomocharis和Lilium之间的形态差异是栖息地专业化的结果（Gao et al. 2015）。百合属和Nomocharis内杂交引起的广泛渐渗（Gao et al. 2013 a，2015）支持单属概念。
Controversy regarding the status of the genus Nomocharis Franchet (1889: 113) has been undergoing since its recognition by Franchet (1889). Recent molecular studies (Nishikawa et al. 1999, Hayashi & Kawano 2000, Nishikawa et al. 2001, Ronsted et al. 2005, Peruzzi et al. 2009) have resolved Nomocharis as being nested within Lilium Linaeus (1753: 302). Results of our own previous studies (Gao et al. 2012, Gao et al. 2013a, Gao et al. 2013b), with expanded sampling of species of Nomocharis have been congruent with those of previous studies by others. Thus recognition of Nomocharis would render Lilium paraphyletic. We prefer to recognize a monophyletic Lilium here, although paraphyletic groups are sometimes advocated in literature (e.g., Brummitt, 2014; Ehrendorfer & Barfuss, 2014; George, 2014; Horandl, 2014; Stuessy & Horandl, 2014; Stuessy et al., 2014). Most recently, we proposed that the morphological divergence between Nomocharis and Lilium was the result of habitat specialization (Gao et al. 2015). The extensive introgression caused by hybridization within Lilium and Nomocharis (Gao et al. 2013a, 2015) supports a single-genus concept.
