“…Species of Lilieae dispersed in the temperate climatic regions of the northern hemisphere (Boufford, 1993;Chen et al, 2000;Kiani et al, 2017): Cardiocrinum species spread over east Asia (Ohara et al, 2006;Yang et al, 2016;Lu et al, 2020) and Notholirion species evolved as endemics in the Himalaya mountains (Li et al, , 2020. Lilium and Fritillaria species are widely distributed in the northern hemisphere, and many Lilium species are densely distributed in east Asia (Gao et al, 2013;Gao, 2016, Gao et al, 2020;Givnish et al, 2016;Liu et al, 2018;Su et al, 2021), whereas species of Fritillaria are mainly distributed in central Asia and the Mediterranean region (Wang et al, 2009;Day et al, 2014;Mustafa and Abdul-Razaq, 2015;Mucciarelli et al, 2016). Many species of Lilieae are distributed mainly in the southern and south-eastern regions of the QTP (Wang et al, 2009;Gao et al, 2013;Li et al, 2020), consistent with the QTP being an intensive distribution center of Lilieae species (Chen et al, 2000;Gao and Gao, 2016;Huang et al, 2018;Li et al, 2020).…”
