Arisaema species from Shikoku Island, Japan

Arisaema species in Japan exhibit extensive morphological variation that has complicated their taxonomy, particularly the debated distinction between Arisaema japonicum and A. serratum. To assess whether A. japonicum represents a distinct lineage or falls within the natural variation of A. serratum, we generated a genomic dataset using genotyping-by-sequencing (GBS). Fresh leaf tissue was collected from 13 individuals representing four morphotypes (n = 7 A. serratum; n = 6 A. japonicum) across five sites on Shikoku Island, Japan, spanning elevational and ecological gradients. Libraries were prepared with ApeKI digestion and sequenced on an Illumina NovaSeq 6000 platform. Reads were quality-filtered, aligned to the draft genome of A. tosaense, and processed to call genome-wide SNPs. Subsequent analyses revealed no reciprocal monophyly between A. japonicum and A. serratum, with individuals instead clustering by geography. This dataset therefore, provides a robust genomic resource for..., , , # Arisaema species from Shikoku Island, Japan

## Description of the data and file structure

This dataset contains the draft genome assembly of *Arisaema tosaense*, a species within the *Araceae* family. The genome was sequenced using PacBio HiFi long-read sequencing technology. The dataset also contains paired reads resulting from GBS sequencing of *Arisaema serratum* and *Arisaema japonicum* individuals from Shikoku Island. This assembly represents a valuable resource for studying the evolutionary genetics, taxonomy, and phylogenomics of *Arisaema* and related taxa.
