Phyllodoce is a small genus of plants in the heather family, Ericaceae.
 They are known commonly as mountainheaths, mountain heaths, or mountain heathers.
 They are native to North America and Eurasia, where they have a circumboreal distribution.
Environmental niche modelling, alternatively known as species distribution modelling, (ecological) niche modelling, predictive habitat distribution modelling, and climate envelope modelling refers to the process of using computer algorithms to predict the distribution of species in geographic space on the basis of a mathematical representation of their known distribution in environmental space (= realized ecological niche).
 The environment is in most cases represented by climate data (such as temperature, and precipitation), but other variables such as soil type, water depth, and land cover can also be used.
 These models allow for interpolating between a limited number of species occurrence and they are used in several research areas in conservation biology, ecology and evolution.
Hydropus is a genus of fungi in the family Marasmiaceae.
 The widespread genus contains about 100 species, especially in tropical areas, but is not well represented in temperate regions.
 About 15 taxa are found in Europe; "H. floccipus" has the widest distribution in western Europe.
 "Hydropus" was circumscribed by Rolf Singer in 1948.
 Species in the genus have fruit bodies with caps that are mycenoid, collybioid, or omphaloid in form.
 Most species occur in tropical and subtropical regions, where they grow as saprobes on rotting wood, forest litter, and mosses.
 Generally, most "Hydropus" species are rare, and several are known only from the type collection, including "H. conicus", "H. moserianus", "H. nitens", and "H. paradoxus".
Sillago is a genus of fish in the family Sillaginidae and the only non-monotypic genus in the family.
 Distinguishing the species can be difficult, with many similar in appearance and colour, forcing the use of swim bladder morphology as a definitive feature.
 All species are benthic in nature and generally coastal fish, living in shallow, protected waters although there are exceptions.
 Minor fisheries exist around various species of "Sillago", making them of minor importance in most of their range.
 This genus has the widest distribution of any smelt-whiting genus, spanning much of the Indo-Pacific.
 The genus ranges from the east coast of Africa to Japan in the east and Southern Australia in the south, with most species concentrated around South East Asia, the Indonesian Archipelago and Australia.
 Many species have overlapping distribution, often making positive identification hard.
The Lusitanian flora is a small assemblage of plants that show a restricted and specific distribution in that they are mostly only to be found in the Iberian Peninsula or south west Ireland.
 Generally, the plants are not found in England or western France even though suitable habitat almost certainly exists in those regions.
 The plants currently number about 15 species in total and include examples such as Irish Fleabane, Strawberry Tree and St Patrick's Cabbage.
 The group is of particular interest and importance since it is currently not understood how the current geographical distribution came about.
 This biogeographical puzzle has been a topic of academic debate since the middle of the 19th century.
 Conflicting, and as yet unresolved theories centre on whether the Irish populations are a relict, surviving from before the last ice age or whether they have been transported there in the last 10,000 years.
 Many of the species are also very restricted in their distribution in Ireland, and have become the centre of intense conservation efforts in recent years, for example the Irish Fleabane.
Dampiera is a genus of plants in the Goodeniaceae family which are endemic to Australia occurring in all states.
 They are herbaceous plants or small shrubs which have blue or purple flowers with yellow centres.
 The genus is named for William Dampier, an English sea captain and scientific observer.
The Hardy Plant Society is a British charity that promotes the cultivation of hardy herbaceous plants.
 The Society was founded in 1957 by a group of gardeners and nurserymen.
 It has approximately 10,000 members and provides information about familiar and less well known perennials, how to grow them and where they may be obtained.
 The Society also works towards ensuring that all garden worthy perennial plants remain in cultivation and have the widest distribution.
 Its President is Roy Lancaster.
Stylidium calcaratum, the book triggerplant, is a dicotyledonous plant that belongs to the genus "Stylidium" (family Stylidiaceae).
 It is an ephemeral annual that grows from 5 to 10 cm tall but can grow larger at 20–30 cm tall in damp forest or scrub habitat.
 The few ovate leaves produced by this plant form basal rosettes around the stem.
 The leaves are around 3–5 mm long on short petioles.
 The scapes are 2–30 cm tall and produce single flowers in smaller plants and up to nine flowers in larger, more robust plants.
 Flowers are pink or white with red spots or lines at the individual petal bases.
 The petals are vertically paired and will fold over to meet each other at night or in adverse weather conditions.
 "S. calcaratum" is endemic to Australia and has a distribution that ranges from Victoria through South Australia and into Western Australia.
 Its habitat is recorded as being wet flats or near creeks and seepages.
 Pollination is achieved by a grey fly, "Comptosia cuneata".
The Aliquandostipitaceae are a family of fungi in the Ascomycota, class Dothideomycetes.
 The family was described by Patrik Inderbitzin in 2001, and the order Jahnulales was created in 2002 to accommodate the family.
 The distinguishing characteristic for members of the family are the unusually wide hyphae ("widest hyphae reported in the ascomycetes") that support the spore-bearing structures, and the presence of ascomata both with and without stalks.
 The genus "Aliquandostipe" has a pantropical distribution, having been found in Central America and southeast Asia; "Jahnula" has a wider distribution.
 Species in the family are saprobic, and are typically found growing on rotting wood.
Bracken ("Pteridium") is a genus of large, coarse ferns in the family Dennstaedtiaceae.
 Ferns (Pteridophyta) are vascular plants that have alternating generations, large plants that produce spores and small plants that produce sex cells (eggs and sperm).
 Brackens are noted for their large, highly divided leaves.
 They are found on all continents except Antarctica and in all environments except deserts, though their typical habitat is moorland.
 The genus probably has the widest distribution of any fern in the world.
