#annual fern

• Anogramma — A genus of small, terrestrial ferns in the Pteridaceae family, characterized by finely dissected fronds and an annual or ephemeral lifecycle unusual for pteridophytes. The best-known species is Anogramma leptophylla, a unique structural plant that survives from year to year primarily as a perennial tuberous gametophyte, colonizing damp, shaded, rocky soils in Mediterranean and temperate climates.
• Anogramma leptophylla — A unique species of small fern in the Pteridaceae family, remarkable for its annual or ephemeral life cycle, an atypical phenomenon among pteridophytes. The plant possesses thin, delicate, translucent fronds, but its ultimate structural feature is that the sporophyte regularly dies off during the dry season, survival from year to year being secured by a perennial tuberous gametophyte colonizing shaded rocky niches in Mediterranean and temperate zones.
