This is a remarkable fern, which has been placed out of doors in the garden in summer, from early in June to October; but it is not vigorous or hardy enough to be generally recommended for this purpose. However, as it may have been noticed in abundance at Battersea Park, I allude to it here. The leaves are rather broad, pointed, and undulating, nearly 3 ft. long, and form roundish, spreading, nest-like tufts. It is a favourite subject in places where large collections of tropical ferns are grown, and in such places a plant may be tried in the open air in a very warm, shady, and perfectly sheltered position.
