Abstract
Lemmaphyllum carnosum var. drymoglossoides (Baker) X. P. Wei, 2013 is a valuable medicinal fern in China. Its complete chloroplast genome was determined using Illumina paired-end sequencing. The genome was 157,571 bp in length with 130 genes, including 87 protein-coding genes, eight ribosomal RNA genes, and 35 tRNA genes. It displayed a quadripartite structure consisting of a small single-copy (SSC) of 21,691 bp, a large single-copy (LSC) of 81,106 bp, and two inverted repeats (IRs) of 27,387 bp, respectively. The phylogenetic results indicated that L. carnosum var. drymoglossoides exhibited the closest relationship with L. intermedium, and this study provided new information for the phylogenetic relationship of the Polypodiaceae family.
