报道福建省蕨类植物一新记录属—穴子蕨属Prosaptia C. Presl，及新记录种—缘生穴子蕨Prosaptia contigua (G. Forst.) C. Presl.。文中提供了相应的生境与特写图片，凭证标本保存于福建师范大学标本馆(FNU)。在形态鉴定的基础上，基于rbcL和atpB基因联合构建系统发育树，结果表明新记录种与NCBI数据库的缘生穴子蕨为同一物种(BP/PP=93/0.99)，为强支持。通过二代高通量全基因组测序，组装和注释了缘生穴子蕨叶绿体基因组，其叶绿体基因组为典型的四分体结构，总长度为148 722 bp，含123个基因(31个tRNA基因、8个rRNA基因和84个蛋白质编码基因)，研究结果为后续水龙骨科系统发育研究提供了数据支持。
A newly recorded genus of ferns, Prosaptia C. Presl, and a newly recorded species, Prosaptia contigua (G. Forst.) C. Presl., have been identified in Fujian Province. The corresponding habitat and detailed images are provided, and the voucher specimens are preserved in the Herbarium of Fujian Normal University (FNU). In addition to morphological identification, a phylogenetic tree was constructed based on the combined genes of rbcL and atpB. The results showed that the newly recorded species matched the P. contigua in the NCBI database (BP/PP=93/0.99), providing strong support. The chloroplast genome genome was sequenced, assembled, and annotated using the second-generation high-throughput whole genomes sequencing, revealing a typical four-stage structure with a total length of 148 722 bp and comprising123 genes (including 31 tRNA genes, 8 rRNA genes and 84 protein-coding genes). These findings provide a solid foundation for subsequent studies on the phylogeny of Polypodiaceae.
