Ophioglossum Azoricum
''Ophioglossum azoricum'', the small adder's-tongue fern or lesser adder's-tongue fern, is a small fern of the family Ophioglossaceae. Distribution ''Ophioglossum azoricum'' is an Atlantic–Mediterranean species native to islands in the northern Atlantic Ocean and adjacent western and southwestern Europe from Greenland, Iceland and the British Isles in the north, to Macaronesia and the Iberian Peninsula in the south. It also occurs in the Toscana region of Italy, Poland, the Czech Republic, and east to Cyprus, Turkey and Lebanon. This species mostly occurs on bare or shortly vegetated ground on exposed coastal clifftops. An exception to this habitat preference is populations in the New Forest, Hampshire, where plants occur in tightly grazed damp grassland in a non-maritime setting.

Spore
In biology, a spore is a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, fungi and protozoa. Bacterial spores are not part of a sexual cycle, but are resistant structures used for survival under unfavourable conditions. Myxozoan spores release amoeboid infectious germs ("amoebulae") into their hosts for parasitic infection, but also reproduce within the hosts through the pairing of two nuclei within the plasmodium, which develops from the amoebula. In plants, spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte. Under favourable conditions the spore can develop into a new organism using mitotic division, producing a multicellular gametophyte, which eventually goes on to produce gametes. Two gametes fuse to form a zygote which develops into a new s ...

Flora Of Great Britain
The flora of Great Britain and Ireland is one of the best documented in the world. There are 1390 native species and over 1100 well-established non-natives documented on the islands. A bibliographic database of the species is compiled by the Botanical Society of Britain and Ireland. Because of the size of the list, it is spread across multiple pages. * Part 1 covers ferns and allies ( Lycopodiopsida, Equisetopsida and Pteridopsida) * Part 2 covers the conifers (Pinopsida) The remaining parts cover the flowering plants (Magnoliopsida): * Part 3, covering a group of dicotyledon families (Lauraceae to Salicaceae) * Part 4, covering another group of dicotyledon families (Brassicaceae to Saxifragaceae) * Part 5, covering the dicotyledon family Rosaceae * Part 6, covering another group of dicotyledon families (Mimosaceae to Dipsacaceae) * Part 7, covering the dicotyledon family Asteraceae * Part 8, covering the monocotyledons (Butomaceae to Orchidaceae) The list gives an Engli ...

Flora Of Italy
The flora of Italy is all the plant life present in the territory of the Italian Republic. The flora of Italy was traditionally estimated to comprise about 5,500 vascular plant species. However, , 7,672 species are recorded in the second edition of the flora of Italy and in its digital archives ''Digital flora of Italy''. In particular, 7,031 are autochthonous and 641 are non native species widely naturalized since more than three decades. Additionally, further 468 exotic species have been recorded as adventitious or naturalized in more recent times. Geobotanically, the Italian flora is shared between the Circumboreal Region and Mediterranean Region. According to the index compiled by the Italian Ministry for the Environment in 2001, 274 vascular plant species were protected. Italy has 1,371 endemic plant species and subspecies. Biodiversity Italy is one of the richest European countries in both plant and animal biodiversity, with a population very rich in endemic forms. Du ...

Flora Of Ireland
Ireland is in the Atlantic European Province of the Circumboreal Region, a floristic region within the Holarctic.

Flora Of Iceland
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ...
