Gentiana is a genus of flowering plants belonging to the gentian family (Gentianaceae), the tribe Gentianeae, and the monophyletic subtribe Gentianinae. With over 300 species, it is considered a large genus. Gentians are notable for their mostly large trumpet-shaped flowers, which are often of an intense blue hue.
Gentiana acaulis, the stemless gentian, or trumpet gentian, is a species of flowering plant in the family Gentianaceae, native to central and southern Europe, from Spain east to the Balkans, growing especially in mountainous regions, such as the Alps and Pyrenees, at heights of 800–3,000 m (2,625–9,843 ft).
Gentiana lutea, the great yellow gentian, is a species of gentian native to the mountains of central and southern Europe.
Centaurea montana, the perennial cornflower, mountain cornflower, bachelor's button, montane knapweed or mountain bluet, is a species of flowering plant in the family Asteraceae, endemic to Europe. It is widespread and common in the more southerly mountain ranges of Europe, but is rarer in the north. It escapes from gardens readily, and has thereby become established in the British Isles, Scandinavia and North America. This plant has become an invasive species in British Columbia, Canada. Centaurea montana grows in meadows and open woodland in the upper montane and sub-alpine zones, in basic areas. It grows to 30–70 centimetres (12–28 in) tall, and flowers mainly from May to August.
Gentiana calycosa is a species of flowering plant in the family Gentianaceae. It is a herbaceous perennial gentian known by the common names explorer's gentian, Rainier pleated gentian, and mountain bog gentian.
Gentianella amarella, the autumn gentian, autumn dwarf gentian, or autumn felwort, is a short biennial plant flowering plant in the gentian family, Gentianaceae. It is found throughout Northern Europe, the western and northern United States, and Canada.
Gentiana newberryi is a species of gentian known by the common names alpine gentian and Newberry's gentian. It is a perennial herb found in western North America.
Gentiana sceptrum is a species of flowering plant in the family Gentianaceae. It is known by the common names king's scepter gentian or king's gentian.
Gentiana setigera is a species of gentian known by the common name Mendocino gentian. It is native to southern Oregon and northern California where it grows in wet places in the California Coast Ranges. It grows in serpentine soils.
Lune Forest is a Site of Special Scientific Interest covering an extensive area of moorland in the Teesdale district of west Durham, England. In the north, where it adjoins the Upper Teesdale and Appleby Fells SSSIs, it extends from Mickle Fell eastward almost as far as Harter Fell, above the hamlet of Thringarth. Its southern limit is marked by the River Balder, upstream from Balderhead Reservoir, where it shares a boundary with Cotherstone Moor SSSI to the south. Grains o' th' Beck Meadows and Close House Mine SSSIs are entirely surrounded by Lune Forest, but do not form part of it.
Thalictrum alpinum is a species of flowering plant in the buttercup family known by the common names alpine meadow-rue and arctic meadow-rue. It is native to Arctic and alpine regions of North America and Eurasia, including Alaska, northern Canada, and Greenland, and it occurs in cold, wet, boggy habitats in high mountains farther south.
Central Europe contains several life zones, depending on location and elevation.
Gentiana cruciata, the star gentian or cross gentian, is a herbaceous perennial flowering plant in the Gentianaceae family.
Gentiana glauca is a species of flowering plant in the gentian family known by the common names pale gentian and glaucous gentian. It is native to eastern Asia and northwestern North America from Alaska to the Northwest Territories to Washington and Montana.
The flora of the U.S. Sierra Nevada alpine zone is characterized by small, low growing, cushion and mat forming plants that can survive the harsh conditions in the high-altitude alpine zone above the timber line. These flora often occur in alpine fell-fields. The Sierra Nevada alpine zone lacks a dominant plant species that characterizes it, so may or may not be called a vegetation type. But it is found above the subalpine forest, which is the highest in a succession of recognized vegetation types at increasing elevations.
Gentiana paradoxa, the Caucasian gentian, is a species of flowering plant in the family Gentianaceae, endemic to the foothills of the Greater Caucasus Mountains in western Asia, near the Black Sea. A compact, mat-forming herbaceous perennial growing to 20 cm (7.9 in) tall and wide, its upright stems of grass-like, linear or lanceolate leaves bear clusters of 5 or 6 large, brilliant blue and white flowers in late summer. It is one of several species of gentians that are valued in cultivation for the unusual bright blue colour of their blooms. However, it is not particularly easy to grow, requiring moist, well-drained, lime-free soil and a position in full sun. It is quite rare in nature.
Gentiana pannonica, the Hungarian gentian or brown gentian, is a species of flowering plant in the family Gentianaceae.
Gentiana pedicellata, the purple stalked gentian, is a plant that belongs to the genus Gentiana.
Gentiana froelichii, commonly known as the Karawanken gentian, is an endemic hemicryptophyte and perennial plant species in the family Gentianaceae, which occurs in southeastern Alps. It can be found in Austria and Slovenia, with a few reported occurrences happening in Italy.
The flora of the Massif Central is rich and diverse. This diversity can be explained by the Massif's large surface area, its position at the intersection of different climatic zones, and its geological variety. The plants that can be found in the very wet western part are not the same as those found in the drier eastern part, and the difference is even greater with the species that can be found in the southern part, which are subject to marked Mediterranean influences. This spatial component is not the only one involved, since exposure, altitude, and the nature of the substrate are also determining factors. For example, there is the classic contrast between south-facing and north-facing slopes, and the differences in vegetation between acidic soils (granite) and basic soils. Although the altitude of the Massif Central is low compared to other mountain ranges such as the Alps or the Pyrenees, there is a clear range of vegetation, from Mediterranean vegetation to sub-alpine grassland. Generally speaking, in most of the Massif Central, there are four distinct levels of vegetation:
