Liparis punctilabris and Liparis nectarina identities

This dataset compiles morphological and geographic information for two closely related orchid species endemic to Réunion Island: Liparis nectarina and Liparis punctilabris. The data were collected as part of W. Buquet’s doctoral research on the taxonomy, phylogeny, and conservation of Liparis species in the Mascarene Islands. Content and structure The dataset includes the following components: • Geographic coordinates: GPS data for each occurrence (latitude, longitude, elevation). • Morphological data: Quantitative measurements (e.g., pseudobulb length, leaf width, lip shape parameters) and qualitative descriptors (e.g., flower color, venation, pubescence), used for morphometric analyses. • Photographic documentation: Dissections photographs of flowers Purpose The dataset was designed to: • Clarify the taxonomic boundaries between L. nectarina and L. punctilabris, which have long been confused in the literature and herbarium collections. • Inform conservation assessments (e.g., IUCN Red List status re-evaluation). • Serve as a reference for future fieldwork and floristic inventories in the Mascarene region. Format and availability The data are stored in tabular format (CSV and XLSX) and the image are stored in a PDF file.本数据集汇编了留尼旺岛特有且亲缘关系密切的两种兰科羊耳蒜属（Liparis）物种——近缘羊耳蒜（Liparis nectarina）与点唇羊耳蒜（Liparis punctilabris）的形态与地理信息。相关数据为W·比凯（W. Buquet）针对马斯克林群岛羊耳蒜属物种的分类学、系统发育及保护开展的博士研究的组成部分。 数据集内容与结构 本数据集包含以下组成部分： • 地理坐标数据：各采集记录的GPS信息，涵盖纬度、经度与海拔高度。 • 形态学数据：用于形态计量分析的定量测量指标（如假鳞茎长度、叶片宽度、唇瓣形状参数等）与定性描述特征（如花色、脉纹、被毛状态等）。 • 摄影记录：花朵解剖的实拍照片。 数据集用途 本数据集旨在达成以下目标： • 厘清近缘羊耳蒜与点唇羊耳蒜之间的分类边界——二者长期以来在学术文献与标本馆馆藏中均存在混淆情况。 • 为物种保护评估提供参考依据（例如重新评估IUCN红色名录等级）。 • 为马斯克林地区未来的野外调查与植物区系清查提供参考资料。 数据格式与可获取性 数据以表格格式存储，包含CSV与XLSX两种格式；影像资料则存储于PDF文件中。
