Hosta clausa (Asparagaceae) in East Asia: Intraspecific chloroplast genome variation and its phylogenomic implications.

ABSTRACT: Hosta species are abundant in northeastern Asia, offering significant ornamental and horticultural value due to their diverse foliage colors and textures, as well as their showy, fragrant flowers. Among the eight taxa naturally distributed in Korea, H. clausa is found in central and northern Korea, as well as northeastern China, providing valuable resources for developing and improving new varieties. Currently, four intraspecific taxa of H. clausa are recognized at the variety level based on reproductive (opened vs. closed perianth), vegetative (leaf shape), and habitat characteristics: var. clausa, var. normalis, var. ensata, and var. geumgangensis. Despite its horticultural and taxonomic importance, little is known about the degree of intraspecific chloroplast genome variation and relati
