It is the first report on complete chloroplast genome of Alsophila costularis, a least concerned relict tree fern. The genome size is 156,675 bp, with the typical quadripartite structure containing a pair of inverted repeats (IRs) of 24,356 bp separated by a large single-copy (LSC) region and a small single-copy (SSC) region of 86,338 bp and 21,625 bp, respectively. A total of 133 genes are predicted, including 89 protein-coding genes, eight ribosomal RNA genes, 33 tRNA genes, and three pseudogenes. The ML phylogenetic tree revealed A. costularisis as sister to Alsophila spinulosa.
