Molecular and morphological evidence reveal Lithocarpus dahuensis and L. Konishii (Fagaceae) are conspecific

To infer phylogenetic relationships between L. dahuensis, L. konishii, and related taxa, and their systematic position within the genus Lithocarpus, we newly generated WGS data for the ten newly sampled individuals (from three individuals of L. dahuensis, six of L. konishii, and one of L. quercifolius). Additionally, we incorporated WGS data from 13 samples representing 9 Lithocarpus species and one Chrysolepis chrysophylla (Douglas ex Hook.) Hjelmq. published by Zhou et al. (2022) from NCBI for the phylogenomic tree reconstruction.

## Description of the data and file structure

This dataset includes whole-genome resequencing data from 20 individuals of Fagaceae, including *L. dahuensis* and *L. konishii*, to assess the taxonomic distinctiveness of *L. dahuensis*. SNP data and a phylogenomic tree were generated to clarify species boundaries.

### Files and variables

#### File: Lithocarpus_SNP__phylogeny_matrix.phy

**Description:** A PHYLIP-format SNP matrix generated from whole-genome resequencing data of *Lithocarpus* individuals, used for phylogenetic analysis.

#### File: Lithocarpus_SNP_ML_tree.treefile

**Description:** Maximum likelihood phylogenetic tree reconstructed from the SNP matrix using IQ-TREE.
