Also unlike bryophytes, fern sporophytes are free-living and only briefly dependent on the maternal gametophyte. The green, photosynthetic part of the plant is technically a megaphyll and in ferns, it is often called a frond. New leaves typically expand by the unrolling of a tight spiral called a crozier or fiddlehead into fronds. [9]
Polypodiales are unique in bearing sporangia with a vertical annulus interrupted by the stalk and stomium. [2] These sporangial characters were used by Johann Jakob Bernhardi to define a group of ferns he called the "Cathetogyratae"; [3] the Pteridophyte Phylogeny Group has suggested reviving this name as the informal term cathetogyrates, to replace the ambiguously circumscribed term "polypods ...
Sometimes called the potato fern, this is a large fern with an edible fleshy rhizome that is used as a food source by some indigenous peoples. The East-Asian genus Christensenia is named in honor of the Danish pteridologist Carl Christensen is an uncommon fern with distinctive fronds resembling a horse chestnut leaf, hence the species ...
Generally, the family is pantropical, but due to the distribution of Pteridium (the most widespread fern genus), Dennstaedtiaceae can be found worldwide. [4] Pteridium is a well adapted early successional genus, generally described as a weed because of its ease of spread.
The Cyatheaceae are a family of ferns, the scaly tree ferns, one of eight families in the order Cyatheales in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). [1] Alternatively, the family may defined much more broadly (Cyatheaceae sensu lato ) as the only family in the Cyatheales, with the PPG I family treated as the subfamily ...
Marsileaceae (/ m ɑːr ˌ s ɪ l i ˈ eɪ s i. iː /) is a small family of heterosporous aquatic and semi-aquatic ferns, though at first sight they do not physically resemble other ferns. The group is commonly known as the "pepperwort family" or as the "water-clover family" because the leaves of the genus Marsilea superficially resemble the ...
Asplenium is a genus of about 700 species of ferns, often treated as the only genus in the family Aspleniaceae, though other authors consider Hymenasplenium separate, based on molecular phylogenetic analysis of DNA sequences, a different chromosome count, and structural differences in the rhizomes.
