Global Rarity Rank: G4G5
A Global Rarity Rank of G4G5 means: Apparently or Demonstrably Secure globally - Uncommon to common in the world, but not rare; usually widespread, but may be rare in some parts of its range; possibly some cause for long-term concern due to declines or other factors.

Did you know?
The underground gametophyte (the separate plant that germinates from the spore and produces the egg and sperm cells) does not produce chlorophyll and is dependent on a fungus for its nutrition. Plants may live underground for more than one year and all of the plants in one population may not be seen every year. This fern was recognized as a separate species in 1927 and was named for Mingan Island in the northern Gulf of St. Lawrence.

State Ranking Justification [-]
