Adiantum bellum (Bermuda maidenhair fern) is a species of fern in the family Pteridaceae, [2] and is native to Bermuda.

Contents

It is 1 of 19 ferns native to Bermuda, the only native maidenhair, and the most prolific fern on the island. [3] [4] [5] It is found only on Bermuda; however, the IPNI reports it also found in Guiana. [6]

Bermuda maidenhair ferns (Adiantum bellum)

Adiantum bellum is deciduous. In the wild it grows in crevices, on cliffs and under rock ledges, in roadside verge, and terrestrially on hillsides. It requires moisture and shade and is often prolific near streams if in well-drained sites. [4] [5] [7] The delicate fronds grow to 5–30 cm (2.0–11.8 in) long, and are fan-shaped, light to medium green with black stems (stipes and rachises). [7] [8] Benjamin D. Gilbert described a variety of A. bellum which he called walsingense; [7] however, it is believed that this is just a variety produced by better soil and moisture conditions. [5]

The other maidenhair fern that now grows wild on Bermuda, Adiantum capillus-veneris , was introduced by Governor Lefroy. [9]

Cultivation

Bermuda maidenhair fern is sometimes grown in gardens; however, it is not hardy and does better indoors. [10] It prefers low to medium light, and moist potting mix. The cultivar Adiantum raddianum 'Pacottii' has been mislabeled as this species in the horticultural trade. [11]

<i>Adiantum</i> Genus of ferns

Adiantum, the maidenhair fern, is a genus of about 250 species of ferns in the subfamily Vittarioideae of the family Pteridaceae, though some researchers place it in its own family, Adiantaceae. The genus name comes from Greek, meaning "unwetted", referring to the fronds' ability to shed water without becoming wet.

<i>Adiantum capillus-veneris</i> Species of fern

Adiantum capillus-veneris, the Southern maidenhair fern, black maidenhair fern, maidenhair fern, and venus hair fern, is a species of ferns in the genus Adiantum and the family Pteridaceae with a subcosmopolitan worldwide distribution. It is cultivated as a popular garden fern and houseplant.

<span class="mw-page-title-main">Ecology of Bermuda</span>

The flora and fauna of Bermuda form part of a unique ecosystem due to Bermuda's isolation from the mainland of North America. The wide range of endemic species and the islands form a distinct ecoregion, the Bermuda subtropical conifer forests.

<span class="mw-page-title-main">Pteridaceae</span> Family of ferns

Pteridaceae is a family of ferns in the order Polypodiales, including some 1150 known species in ca 45 genera, divided over five subfamilies. The family includes four groups of genera that are sometimes recognized as separate families: the adiantoid, cheilanthoid, pteridoid, and hemionitidoid ferns. Relationships among these groups remain unclear, and although some recent genetic analyses of the Pteridales suggest that neither the family Pteridaceae nor the major groups within it are all monophyletic, as yet these analyses are insufficiently comprehensive and robust to provide good support for a revision of the order at the family level.

<i>Adiantum diaphanum</i> Species of plant

Adiantum diaphanum, the filmy maidenhair fern, is a species of fern in the genus Adiantum, native to East Asia and Australasia, from southern Japan south to New Zealand. It grows to 20 cm long at the most, with very dark green fronds covered with bristles.

Over 60 specimens were then successfully cultivated at Royal Botanic Gardens, Kew and on Ascension Island. It is now classified as Critically Endangered.

<i>Adiantum viridimontanum</i> Species of fern

Adiantum viridimontanum, commonly known as Green Mountain maidenhair fern, is a fern found only in outcrops of serpentine rock in New England and Eastern Canada. The leaf blade is cut into finger-like segments, themselves once-divided, which are borne on the outer side of a curved, dark, glossy rachis. These finger-like segments are not individual leaves, but parts of a single compound leaf. The "fingers" may be drooping or erect, depending on whether the individual fern grows in shade or sunlight. Spores are borne under false indusia at the edge of the subdivisions of the leaf, a characteristic unique to the genus Adiantum.

<i>Adiantum raddianum</i> Species of fern

Adiantum raddianum, the Delta maidenhair fern, is one of the most popular ferns to grow indoors. It is native to South America and its common name comes from its shiny, dark leafstalks that resemble human hair. It typically grows about 17–19 in (43–48 cm) tall and up to 22 in (56 cm) wide. In the wild, it is found on forest floors, rock crevices, river banks, coastal cliffs, and basalt banks along trails and streams. The triangular fronds are semi-erect in the beginning then droop gracefully as they age and can be up to 12 inches (30 cm) long by 6 inches (15 cm) wide. The genus name Adiantum comes from the Greek word "adiantos", meaning "unwetted".
