Anogramma leptophylla is a species of fern in the Pteridaceae family. It is found worldwide in temperate and subtropical regions. A rarity in the Pteridophyta, it is a fern whose sporophyte tends to have an annual life cycle. The gametophytes of this species have the ability to become dormant and wait as much as two and a half years until conditions are appropriate for the sporophyte stage of the life-cycle.
