Dryopteris shibipedis was once treated as an extinct species in the Red List (2007) by the Japanese Ministry of the Environment, but 'rediscovered' in the Tsukuba Botanical Garden. To clarify its origin, using 'overlooked' cultivated stocks we analyzed nuclear PgiC intron sequences. As the PgiC genotype of D. shibipedis can be explained by a combination of alleles of D. kinkiensis and those of D. pacifica, the hypothesis of hybrid origin of the species is supported.
中华阴地蕨曾于 2007 年被日本环境省列入《红色名录》（Red List）视为灭绝物种，但后在筑波植物园“重现”。为明确其起源，我们利用“被忽视”的栽培种群对核 PgiC 内含子序列进行了分析。由于中华阴地蕨的 PgiC 基因型可由关阴蕨和阔羽阴地蕨等位基因的组合来解释，因此支持该物种的杂交起源假说。
