The complete chloroplast genome of Leptochilus hemionitideus, a traditional Chinese medical fern.

The complete chloroplast genome of Leptochilus hemionitideus was sequenced. Its length is 156,083 bp with 44.2% GC content. The genome exhibits typical quadripartite with two inverted repeat regions (24,594 bp, each) separated by a large single-copy (LSC, 81,403 bp) region and a small single-copy (SSC, 25,492 bp) region. It has 131 genes, including 87 protein-coding genes, 34 tRNA genes, eight rRNA genes and two pseudogenes. Maximum-likelihood phylogenetic tree indicated that L. hemionitideus was closely related to Lepisorus clathratus. The complete chloroplast genome of L. hemionitideus would provide very valuable molecular information for further inferring the relationships of the microsoroid ferns.
