Neoblechnum is a genus of ferns in the family Blechnaceae, subfamily Blechnoideae, with a single species Neoblechnum brasiliense, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). [1] The genus is accepted in a 2016 classification of the family Blechnaceae, [3] but other sources sink it into a very broadly defined Blechnum, equivalent to the whole of the PPG I subfamily; [4] the species is then known as Blechnum brasiliense. It is called Brazilian dwarf tree fern, red Brazilian tree fern, and red dwarf tree fern. [5] [6]

Description

The erect rhizome of Neoblechnum brasiliense forms a thin stipe-stubbed trunk up to 30 centimetres (12 in) in height. The new foliage is a striking deep red color. As the fronds mature it turns to a glossy green. [7] On some selections, the new fronds emerge a pinkish-red.

Distribution

The fern is native to the warm and humid subtropical forests of South America. [7]

Habitats include: [5]

Cultivation

Neoblechnum brasiliense is cultivated as an ornamental plant. [7] In the UK (under the synonym Blechnum brasiliense) it has gained the Royal Horticultural Society's Award of Garden Merit. [8] As it will not tolerate temperatures below 15 °C (59 °F) it must be grown under glass all year in temperate regions.

Marattiaceae is the only family of extant (living) ferns in the order Marattiales. In the Pteridophyte Phylogeny Group classification of 2016, Marattiales is the only order in the subclass Marattiidae. The family has six genera and about 110 species. Many are different in appearance from other ferns, having large fronds and fleshy rootstocks.

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

Blechnaceae is a family of ferns in the order Polypodiales, with a cosmopolitan distribution. Its status as a family and the number of genera included have both varied considerably. In the Pteridophyte Phylogeny Group classification of 2016, the family has 24 genera, and excludes genera placed in the separate family Onocleaceae. The family is divided into three subfamilies, including Blechnoideae s.s. Alternatively, the entire family may be treated as the subfamily Blechnoideae s.l. of a very broadly defined family Aspleniaceae, and include genera others place in Onocleaceae.

<i>Lomaria</i> Genus of ferns

Lomaria is a genus of ferns belonging to the family Blechnaceae.

<i>Blechnum</i> Genus of ferns in the family Blechnaceae

Blechnum, known as hard fern, is a genus of ferns in the family Blechnaceae, subfamily Blechnoideae, according to the Pteridophyte Phylogeny Group classification of 2016. Two very different circumscriptions of the genus are used by different authors. In the PPG I system, based on Gasper et al. (2016), Blechnum is one of 18 genera in the subfamily Blechnoideae, and has about 30 species. Other sources use a very broadly defined Blechnum s.l., including accepting only two other genera in the subfamily. The genus then has about 250 species. In the PPG I circumscription, the genus is mostly neotropical, with a few southern African species.

<i>Struthiopteris spicant</i> Species of fern in the family Blechnaceae

Struthiopteris spicant, syn. Blechnum spicant, is a species of fern in the family Blechnaceae, known by the common names hard-fern or deer fern. It is native to Europe, western Asia, northern Africa, and western North America. Like some other species in the family Blechnaceae, it has two types of leaves. The sterile leaves have flat, wavy-margined leaflets 5 to 8 millimeters wide, while the fertile leaves have much narrower leaflets, each with two thick rows of sori on the underside.

<i>Doodia</i> Genus of ferns

Doodia is a genus of ferns in the family Blechnaceae, subfamily Blechnoideae, in the suborder Aspleniineae. It is named after Samuel Doody (1656-1706), an English botanist. Distribution of the genus includes parts of Australia and New Zealand.
