Molecular phylogenetic studies of Hosta pulchella (Asparagaceae) and its relatives, which are native to Japan, have been conducted and resulted in a highly resolved phylogeny. Specifically, the relationship of H. pulchella to H. alata Hatusima, nom. nud. is investigated. These data include genome-wide SNPs obtained through conducting multiplexed ISSR genotyping by sequencing (MIG-seq). Based on these phylogenetic results, morphological observations, distribution, and differences in flowering periods of H. alata collections sympatric with H. pulchella, we find the two species closely related, but distinct. As such, we formally describe Hosta alatasp. nov. from the Oita Prefecture of Kyushu island, southwestern Japan.

Hosta alata (Asparagaceae) 作为一个新物种的验证及其系统发育亲和力

已经对原产于日本的 Hosta pulchella (Asparagaceae) 及其亲属进行了分子系统发育研究，并得出了高度解析的系统发育。具体来说，H. pulchella 与 H. alata Hatusima, nom. 的关系。裸体。被调查。这些数据包括通过测序 (MIG-seq) 进行多重 ISSR 基因分型获得的全基因组 SNP。基于这些系统发育结果、形态观察、分布和与 H. pulchella 同域的 H. alata 集合的开花期差异，我们发现这两个物种密切相关，但又不同。因此，我们正式描述了 Hosta alatasp。十一月 来自日本西南部九州岛的大分县。
