原生地・分布（英語）:

説明（英語）: Genus of 150-200 species of usually evergreen, rhizomatous, terrestrial ferns found mostly in moist, sheltered, acid sites in temperate and tropical regions. The rhizomes are erect or creeping, often densely covered with black scales, and bear pinnate or pinnatifid, rarely simple, usually leathery fronds. Fertile fronds are generally erect, in the centres of the frond rosettes. Linear sori are arranged in 2 rows along the midrib of each frond lobe or segment. Some species form small "trunks". Grow in woodland, in a shady herbaceous border, or in a rock garden. In frost-prone areas, grow tender species in a warm greenhouse or conservatory.

耐寒性（英語）: Fully hardy to frost tender. B. discolor survives to -10°C (14°F) with some protection.
