- The genome includes 115 genes, offering insights into fern evolution.

## Abstract

Bolbitis angustipinna (Hayata) H. Ito is a rare ornamental fern primarily distributed throughout East Asia and Southeast Asia. Its complete chloroplast genome was assembled, and a phylogenetic tree was constructed using 15 fern species. The genome is 152,562 base pairs, with a large single-copy region (82,712 bp), a small single-copy region (21,403 bp), and two inverted repeat regions (24,208 bp). It encodes 115 genes, including 72 protein-coding genes, 35 tRNA genes, and 8 rRNA genes. Phylogenetic analysis shows that B. angustipinna is most closely related to B. deltigera, providing valuable genetic and evolutionary insights.
