Blechnum longistipitatum

A little-known Blechnum recorded only from Cocos Island (Isla del Coco), Costa Rica's remote Pacific island, around 570 m in its permanently wet cloud forest. Treat it as a warm, constantly humid forest-floor fern that never expects a dry season.

Where it grows wild

All records come from the upper slopes of Cocos Island, which are covered in very wet, misty forest. Like other Blechnum there it likely grows terrestrially on shaded banks and the forest floor.

Recorded at about 567 m, near the island's highest ground.
