Fragile Fern – Cystopteris fragilis

Gigalum Island or Gigalum is a tiny, private^[1] uninhabited^[2] island off the southeast coast of Gigha in Scotland.

Gigalum has a modern house in the middle, and gives its name to the strait between it and the main island, "Caolas Gigalum". There is also the "Gigalum Rocks" a reef to the east, and about one mile (1.5 kilometres) north-northeast of Gigalum Island itself, "Sgeir Gigalum". It is also flanked by another islet, "Eilean na h-Uilinn", literally "Island of the Elbow".
