The origins and early history of the BPS at the time of "Pteridomania" is described in the book The Victorian Fern Craze. [2] The BPS celebrated its centenary in 1991; amongst other things, it was marked by the publication of the book, A World of Ferns. [3] The British Pteridological Society is a registered charity: No. 1092399. [4]
Cryptogramma crispa, the parsley fern, [2] is an Arctic–alpine species of fern. It produces separate sterile and fertile fronds, up to 30 cm (12 in) tall, and is a pioneer species on acidic screes .
This fern can also be found in areas such as subtropical America, parts of southern Africa and other humid or sub-humid climate areas. This fern is an epiphyte, or air plant, which means it attaches itself to other plants and gets its nutrients from the air and from water and nutrients that collect on the outer surface of bark.
Below are lists of extant fern families and subfamilies using the classification scheme proposed by the Pteridophyte Phylogeny Group in 2016 (PPG I). [1] The scheme is based on molecular phylogenetic studies, and also draws on earlier classifications, [ 1 ] particularly those by Smith et al. (2006), [ 2 ] Chase and Reveal (2009), [ 3 ] and ...
The ferns (Polypodiopsida or Polypodiophyta) are a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers.They differ from mosses by being vascular, i.e., having specialized tissues that conduct water and nutrients, and in having life cycles in which the branched sporophyte is the dominant phase.
Pteridospermatophyta, also called "pteridosperms" or "seed ferns" are a polyphyletic [1] grouping of extinct seed-producing plants. The earliest fossil evidence for plants of this type are the lyginopterids of late Devonian age. [ 2 ]
The fern grows well in well-drained soil under medium levels of light. It needs to be protected from slugs and snails. [8] Campyloneurum phyllitidis was grown in England during the Victorian era, when ferns were particularly popular (the phenomenon known as pteridomania). The fern was described by an author of the time, Shirley Hibberd, as ...
Nephrolepis is a genus of about 30 species of ferns. It is the only genus in the family Nephrolepidaceae, placed in the suborder Aspleniineae (eupolypods I) of the order Polypodiales in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). [1] (It is placed in the Dryopteridaceae in some other classifications. [2])
