Mickelia is a genus of ferns in the family Dryopteridaceae, subfamily Elaphoglossoideae, in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). [2] It is one of the six genera of bolbitidoid ferns and is sister to the very large genus Elaphoglossum . [3] It consists of about 10 species. [1] [4] All are native to the neotropics.

Description

Hemiepiphytic or terrestrial ferns. Rhizomes dorsiventral, the ventral meristele elongate in cross section. Phyllopodia absent. Leaves articulate at base or continuous with the rhizome, dimorphic as sporophylls and trophophylls, the sporophylls having longer petioles and smaller pinnae. Fronds never differentiated into bathyphylls and acrophylls as in the bolbitidoid genera Lomagramma , Arthrobotrya , and Teratophyllum . Fronds singly pinnate or bipinnate with a single, free, basal segment on each of the basal pinnae. Pinnae articulate or continuous with the rachis; terminal pinna conform (similar in size and shape to the lateral pinnae). Veins variously anastomosing (not free); veinlets usually included in the areoles. Sori acrostichoid (covering the entire abaxial surface of the leaf); Paraphyses absent. Spores monolete.

Comparative anatomy

No single character is known to distinguish Mickelia from Bolbitis , but the rhizomes of five species of Mickelia have been examined and found to have ground tissue that is greenish, instead of the whitish color found in most ferns. The greenish rhizome ground tissue might be a synapomorphy for Mickelia. Seven species of Mickelia are hemiepiphytes, whereas all of the Bolbitis species are terrestrial. The location of vegetative buds, when present, is different in the two genera.

Taxonomy

The genus Mickelia was erected in 2010, following a molecular phylogenetic study of the bolbitidoid ferns, based on DNA sequences of the chloroplast intergenic spacers trnL-F and rps4-trnS. [3] Mickelia was named for the American pteridologist John Thomas Mickel, who contributed much regarding Elaphoglossum , the closest relative of Mickelia. [5]

Six species of Mickelia had previously been in the genus Bolbitis. Mickelia pradoi and Mickelia furcata were first described in the paper that established Mickelia. [4] Mickelia scandens was resurrected from Mickelia guianensis, which had previously been in Lomagramma because of its venation pattern. These two had been treated as a single species since the time when they were both in the genus Acrostichum . For this reason, the most recent species name that had been applied to Mickelia scandens was Acrostichum scandens. [4]

The species that had been in Bolbitis were described in a monograph of that genus in 1977. [6] The mesoamerican species of Bolbitis were given an updated treatment in 1995 [7] and detailed biogeographic information for these was published in 2004. [8] Mickelia was first described in a synopsis of the genus that did not repeat much of the information published in previous works.

Phylogeny

The phylogenetic tree below is based on one that was published in 2010. [3] The positions of Mickelia pradoi and Mickelia lindigii are based on morphology only. Mickelia furcata and Mickelia pergamentacea are omitted because they have not been sampled for DNA and morphology does not clearly indicate their affinities. Mickelia furcata is known from only one specimen collected in 1985 and lacking fertile fronds. [4]

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

The Dryopteridaceae are a family of leptosporangiate ferns in the order Polypodiales. They are known colloquially as the wood ferns. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the family is placed in the suborder Polypodiineae. Alternatively, it may be treated as the subfamily Dryopteridoideae of a very broadly defined family Polypodiaceae sensu lato.

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

Polypodiaceae is a family of ferns. In the Pteridophyte Phylogeny Group classification of 2016, the family includes around 65 genera and an estimated 1,650 species and is placed in the order Polypodiales, suborder Polypodiineae. A broader circumscription has also been used, in which the family includes other families kept separate in PPG I. Nearly all species are epiphytes, but some are terrestrial.

<i>Microsorum</i> Genus of ferns

Microsorum is a genus of ferns in the family Polypodiaceae, subfamily Microsoroideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). The species are tropical. Like most ferns, they grow from rhizomes, rather than roots. The genus name is often misspelled "Microsorium" or "Microsoreum". It includes some species that are lithophytic rheophytes.

Mickelia nicotianifolia is a species of fern in the family Dryopteridaceae, subfamily Elaphoglossoideae. It has a widespread distribution in Central America and northern South America.

<i>Hypolepis</i> (plant) Genus of ferns

Hypolepis (beadfern) is a genus of ferns described as a genus in 1806. The word is derived from Greek, meaning "under scale". It is found in tropical and subtropical regions, primarily in the New World but also in the Old World and on various oceanic islands.

<i>Diplazium</i> Genus of ferns

Diplazium is a genus of ferns that specifically includes the approximately 400 known species of twinsorus ferns. The Greek root is diplazein meaning double: the indusia in this genus lie on both sides of the vein. These ferns were earlier considered part of either the Athyriaceae, Dryopteridaceae, Aspleniaceae, or Polypodiaceae families or recognized as belonging to their own taxonomic family. The Pteridophyte Phylogeny Group classification of 2016 places the genus in the Athyriaceae. The taxonomy of the genus is difficult and poorly known, and by 2009 has never been the subject of a complete monographic study. Their distribution is pantropical, with a few species extending into temperate areas.

Plenasium banksiifolium is a fern in the family Osmundaceae. The genus Plenasium is recognized in the Pteridophyte Phylogeny Group classification of 2016 (PPG I); however, some sources place all Plenasium species in a more broadly defined Osmunda, treating this species as Osmunda banksiifolia. It is native along the Pacific coast of Asia, being found in the Kamchatka Peninsula, the Ryukyu Islands, Japan, southeast China, Taiwan, the Philippines, Borneo, Sulawesi and Java. P. banksiifolium, which can reach a height of 1.5 m, is the largest species in the genus and has ornamental value.

<span class="mw-page-title-main">Elaphoglossoideae</span> Subfamily of ferns

Elaphoglossoideae is a subfamily of the fern family Dryopteridaceae. It has previously been regarded as the family Elaphoglossaceae. As circumscribed by the Pteridophyte Phylogeny Group in their 2016 classification, the subfamily excludes the Polybotryoideae, which are kept separate. It can be divided into three clades: the bolbitidoid ferns, genus Pleocnemia, sister clade to the bolbititoids, and the lastreopsid ferns, sister to the combination of the first two clades.

<i>Myriopteris rufa</i> Species of fern

Myriopteris rufa, commonly known as Eaton's lip fern, is a moderately-sized fern of Mexico and the southwestern United States, with outlying populations in Costa Rica and the Appalachian Mountains. One of the cheilanthoid ferns, it was usually classified in the genus Cheilanthes, as Cheilanthes eatonii, until 2013, when the genus Myriopteris was again recognized as separate from Cheilanthes. It typically grows in rocky habitats, most frequently on limestone but also sometimes on basalt or shale.
