''Adiantum bellum'' (Bermuda Maidenhair Fern) is a species of fern in the genus ''Adiantum'' (maidenhairs), and is native to Bermuda. It is 1 of 19 ferns native to Bermuda, the only native maidenhair, and the most prolific fern on the island.〔("Bermuda's Flora" ''Bermuda Online'' )〕〔Phillips-Watlington, Christine (1996) ''Bermuda's Botanical Wonderland: a field guide'' Macmillan Education, London, ISBN 0-333-60652-3〕〔Rugg, Harold Goddard (January 1912) "Random Notes on Bermuda Ferns" ''American Fern Journal'' 2(1): pp. 16-18〕 It is found only on Bermuda; however the IPNI reports it also found in Guiana.〔("Adiantaceae ''Adiantum bellum'' Moore" ''The International Plant Names Index'' )〕 ''A. bellum'' is deciduous. In the wild it grows in crevices, on cliffs and under rock ledges, in roadside verge, and terrestrially on hillsides. It does require moisture and shade, and is often prolific near streams if in well-drained sites.〔〔〔Gilbert, Benjamin D. (December 1898) "Revision of the Bermuda Ferns" ''Bulletin of the Torrey Botanical Club'' 25(12): pp. 593-604〕 The delicate fronds grow to 5–30 cm long, and are fan-shaped, light to medium green with black stems (stipes and rachises).〔〔Moore, Thomas (1879) ''Gardener's Chronicle'' 2nd series, 11: 172 f. 24〕 Benjamin D. Gilbert described a variety of ''A. bellum'' which he called ''walsingense'';〔 however, it is believed that this is just a variety produced by better soil and moisture conditions.〔 The other maidenhair fern that now grows wild on Bermuda, ''Adiantum capillus-veneris'', was introduced by Governor Lefroy.〔Gilbert, Benjamin D. (December 1898) "Revision of the Bermuda Ferns" ''Bulletin of the Torrey Botanical Club'' 25(12): pp. 593-604, p. 595〕 Bermuda Maidenhair Fern is sometimes grown in gardens; however, it is not hardy and does better indoors.〔Taylor, Earle W.
