Integrative evidence reveals a new species and traces of hybridization in Fritillaria (Liliaceae) from the Qinghai-Tibet Plateau

The genus Fritillaria presents significant taxonomic challenges due to its morphological plasticity and complex evolutionary history. We herein describe Fritillaria elegans Xin L. Zhao & Y.D. Qi, a new species from Sichuan and Qinghai Provinces, China, and investigate the phylogenetic relationships and speciation processes within the plateau endemic clade using an integrative approach.
