Delimiting species boundaries in Hosta section Capitatae (Asparagaceae) using MIG-seq and morphological analyses: taxonomic revision with new taxa from Korea and Japan

Our findings identified three species and two varieties in the section <i>Capitatae</i>. In particular, we described two new taxa, <i>H. pseudonakaiana</i> sp. nov. and <i>H. nakaiana</i> var. <i>wandoensis</i> var. nov., from Japan (Shikoku) and Korea (southern Jeollanam-do), respectively. Our study provides the most comprehensive framework for the classification of the section <i>Capitatae</i>, ultimately advancing the taxonomy of the genus <i>Hosta</i>.
