Isoëtes heldreichii
Also called Pindus Quillwort
Isoetes heldreichii, the Pindus quillwort, is a critically endangered aquatic fern ally known only from one site in Greece and possibly extinct in the wild. It grew submerged in clear, spring-fed pools and is not realistically grown by home gardeners.
Isoetes heldreichii, or Pindus quillwort, is a species of lycopod. It is critically endangered. Some think it extinct as it was last seen in 1885.
Isoetes heldreichii is known only from its type locality at Palaiokastro, near the modern city of Karditsa in central Greece. The original habitat was a cluster of perennial springs at the foot of Mount Pindus, where Haussknecht collected submerged plants in July 1885. Those springs were later diverted to supply drinking water to Karditsa, and the pool in which the quillwort grew has disappeared. Despite targeted searches, no further populations have been located, and the species is therefore regarded as extinct in the wild.
