Rumohra
''Rumohra'' is a genus of ferns in the family Dryopteridaceae, subfamily Elaphoglossoideae, in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). The fronds of species within this genus contain round sori (reproductive clusters) on the underside of the pinnae (leaflets) unlike many other ferns which have separate specialized reproductive fronds. Many of the sori have peltate indusia and have prominent scales on the stipes of the fronds. Species have a wide distribution; for example, ''Rumohra adiantiformis'' is found in the Old World as well as the New World, including such diverse places as the Galapagos Islands and New Zealand.

Sorus
A sorus (pl. sori) is a cluster of sporangia (structures producing and containing spores) in ferns and fungi. A coenosorus (plural coenosori) is a compound sorus composed of multiple, fused sori. Etymology This New Latin word is from Ancient Greek σωρός (''sōrós'' 'stack, pile, heap'). Structure In lichens and other fungi, the sorus is surrounded by an external layer. In some red algae, it may take the form of depression into the thallus. In ferns, the sori form a yellowish or brownish mass on the edge or underside of a fertile frond. In some species, they are protected during development by a scale or film of tissue called the indusium, which forms an umbrella-like cover. Lifecycle significance Sori occur on the sporophyte generation, the sporangia within producing haploid meiospores. As the sporangia mature, the indusium shrivels so that spore release is unimpeded. The sporangia then burst and release the spores. As an aid to identification The shape, arrangement ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elaphoglossoideae
Elaphoglossoideae is a subfamily of the fern family Dryopteridaceae 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 .... It has previously been regarded as the family Elaphoglossaceae. As circumscribed by the Pteridophyte Phylogeny Group in their 2016 classification (PPG I), the subfamily excludes the Polybotryoideae, which are kept separate. It can be divided into three clades: the bolbitidoid ferns ('' Arthrobotrya'', '' Bolbitis'', '' Elaphoglossum'', '' Lomagramma'', '' Mickelia'', '' Teratophyllum''), genus '' Pleocnemia'', sister clade to the bolbititoids, and the lastreopsid ferns ('' Lastreopsis'', '' Megalastrum'', '' Parapolystichum'', '' Ruhmora''), sister to the combination of the first two clades.

Dryopteridaceae
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''. The family contains about 1700 species and has a cosmopolitan distribution. Species may be terrestrial, epipetric, hemiepiphytic, or epiphytic. Many are cultivated as ornamental plants. The largest genera are ''Elaphoglossum'' (600+), ''Polystichum'' (260), ''Dryopteris'' (225), and ''Ctenitis'' (150). These four genera contain about 70% of the species. Dryopteridaceae diverged from the other families in eupolypods I about 100 million years ago. Description The rhizomes are often stout, creeping, ascending, or erect, and sometimes scandent or climbing, with nonclathrate scales at api ...
