Reevaluating monotypic Eleutherostylis from New Guinea and the Moluccas, and its inclusion in Grewia (Malvaceae: Grewioideae)

Morphological and molecular phylogenetic evidence indicate that Eleutherostylis Burret (Malvaceae: Grewioideae), a monotypic genus described from New Guinea, is best considered a synonym of Grewia L., a species-rich genus widespread across the paleotropics and found in Africa, Arabia, Asia, Australia, and the western Pacific. A new combination based on E. renistipulata Burret, G. renistipulata (Burret) Dorr, comb. nov., is proposed. Original material of the basionym could not be located and a neotype is designated. A lectotype is designated for G. morotaiensis Kosterm., a synonym of G. renistipulata., This DNA dataset, based on nuclear ribosomal Internal Transcribed Spacer (ITS), is designed to reconstruct phylogenetic relationships of Eleutherostylis (Malvaceae) and is derived from fluorescent Sanger sequencing on an ABI 3730xl DNA Analyzer. The reads were assembled with Sequencher v5.2.4 and consensus sequences were aligned with MAFFT v.7.272 (Katoh and Standley 2013) under the G-INS-i refinement method followed by minor manual refinements based on a similarity criterion., , # Reevaluating monotypic Eleutherostylis from New Guinea and the Moluccas, and its inclusion in Grewia (Malvaceae: Grewioideae)

## Description of the data and file structure

This dataset is in the NEXUS file format with commands designed to be executed in PAUP*, and matrix derivatives then analyzed with other phylogenetic analysis programs. The dataset has pseudo-phylogenetic taxon order and a 119 bp deletion set (masking) is specified in the matrix which must be removed from brackets if implemented by the Excl...

形态学与分子系统发育证据表明，发表于新几内亚的单型属Eleutherostylis Burret（锦葵科Malvaceae：扁担杆亚科Grewioideae）应被最优处理为Grewia L.的同物异名；后者为物种丰富的广布古热带属，分布于非洲、阿拉伯半岛、亚洲、澳大利亚及西太平洋区域。本文提出基于E. renistipulata Burret的新组合：G. renistipulata (Burret) Dorr, comb. nov.。因无法寻获该基名的原始标本材料，故指定一新模式标本。同时为G. renistipulata的同物异名G. morotaiensis Kosterm.指定选模式标本。

本DNA数据集基于核核糖体内部转录间隔区（Internal Transcribed Spacer, ITS）构建，旨在重建Eleutherostylis（锦葵科）的系统发育关系，数据来源于ABI 3730xl DNA分析仪上的荧光Sanger测序。测序读段通过Sequencher v5.2.4进行组装，共识序列采用MAFFT v7.272（Katoh及Standley 2013）以G-INS-i优化方法进行比对，随后基于相似性标准进行少量手动校正。

## 数据与文件结构说明
本数据集采用NEXUS文件格式，包含适配PAUP*软件运行的命令，矩阵衍生文件可通过其他系统发育分析程序进行处理。数据集采用拟系统发育类群排序，矩阵中指定了119 bp缺失集（屏蔽），若通过Excl命令实现该屏蔽，则需将方括号移除。
