Dryopteris shibpedis is a species of fern native Japan that was declared extinct in 2007, that has since been rediscovered in the Tsukuba Botanical Garden.
The embryo of the D. shibipedis has been known, however, to develop without fertilization, and can reproduce asexually, therefore ensuring stability across multiple generations.
This particular species of fern has only been rediscovered in one small place in Japan, having been declared extinct in 2007, then was immediately rebutted due to confirmation of sightings of the fern in the botanical garden in one town in southwest Japan.
The species is unlikely to move out of that region for quite some time and will most likely remain small in numbers for a while due to its relative newness to its locale.
D. shibipedis is currently on a list of 886 endangered pteridophyta taxa around the globe, of which those in the most danger of going extinct are found in Asia.
