剑叶鳞毛虫曾被日本环境省列为《红色名录》(2007)中的灭绝物种，但在筑波植物园重新被发现。为了阐明其来源，我们利用被忽视的栽培种群分析了核PGIC内含子序列。由于该种的PGIC基因可以用金龟子和太平洋石龙子的等位基因组合来解释，因此支持该种的杂交起源假说。
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.
