摘要： 本文报道了采自新疆维吾尔自治区乌恰县的石竹科刺石竹属一中国新记录种——紫纹刺石竹（Acanthophyllum coloratumSchischk.）。基于形态学比较和nrITS序列的分子系统学分析明确该物种的分类地位；从基因组重测序数据中组装、注释并校正其质体基因组，分析质体基因组特征。形态学上，新采集物种的主要识别特征为叶线形、对生、被糙毛，花序顶生、紧缩呈头状，花瓣淡粉白色、具浅紫色中脉，花萼外部被糙毛无腺体，这些特征与紫纹刺石竹A. coloratum的变种A. coloratumvar.eglandulosumLazkov一致，与原变种A. coloratumvar.coloratum（中国未有分布）的区别在于花萼外部被糙毛无腺体；基于nrITS序列构建的刺石竹属的最大似然树显示，新采集物种（YZP001504）与A. coloratum聚为一高支持率的单系分支（BS=100%），结合形态学差异，确认新采集物种为A. coloratumvar.eglandulosum，将其中文名拟为无腺紫纹刺石竹；质体基因组特征分析结果表明，无腺紫纹刺石竹的质体基因组为典型的四分体结构，总长度为149532 bp，含126个基因（包括81个蛋白质编码基因、8个rRNA基因和37个tRNA基因）。此新记录的发现，为中国高等植物增添了新类群，对揭示中亚植物区系迁移路线具有重要的科学价值。

Abstract: This study reported a newly recorded species of Caryophyllaceae in China,Acanthophyllum coloratumSchischk., which was found in Wuqia County, Xinjiang Uygur Autonomous Region. Its taxonomic status was confirmed through morphological comparison and molecular phylogenetic analysis based on nrITS sequences. The plastome was assembled, annotated, and corrected from whole-genome resequencing data, and its characteristics were further analyzed. Morphologically, the newly found plant exhibited key diagnostic traits including linear, opposite leaves covered with strigose hairs, terminal compact capitate inflorescences, pale pinkish-white petals with light purple midveins, and an eglandular and strigose outer surface of the calyx, which were consistent withA. coloratumvar.eglandulosum. This variety differed from the nominate variety,A. coloratumvar.coloratum(which has not been recorded in China) only by the absence of glandular hairs on the calyx. A maximum likelihood tree of the genusAcanthophyllum, constructed using nrITS sequences, showed that the newly found plant (specimen voucher number: YZP001504) formed a highly supported monophyletic clade (BS=100%) with the typical varietyA. coloratumvar.coloratum. Integrating these morphological and molecular results, this plant was confirmed asA. coloratumvar.eglandulosum, for which the Chinese name “wuxian ziwen cishizhu” is proposed. Its plastome had a typical quadripartite structure with a total length of 149532 bp, containing 126 genes, including 81 protein-coding genes, 8 rRNA genes, and 37 tRNA genes. This discovery not only added a new taxon to the diversity of higher plants in China but also provided significant scientific value for understanding the migration routes of the Central Asian flora.
