Geum Bulgaricum
''Geum bulgaricum'' is a species of flowering plant of the genus ''Geum'' (avens) in the family Rosaceae. A perennial herbaceous plant, it has small, bell-like yellow flowers, and is native to a few mountains on the Balkan Peninsula. It is found throughout the range of the Accursed Mountains that span the borders between Albania, Montenegro and Kosovo, in the mountain of Kunora e Lurës in eastern Albania, on Sinjajevina and Žijovo/Kučke Planine in Montenegro, the mountains of Prenj, Čvrsnica and Čabulja in southern Bosnia and Herzegovina, and in Bulgaria's Rila mountain. It grows in the alpine and subalpine zones (typically at elevations between 1800 and 2600m, but it can go as low as 1200m in the Accursed Mountains and up to 2700m in Rila). Its habitat ranges across mountain meadows, rocky slopes, and scree fields, and it can also be encountered among krummholz pine vegetation. It is associated with silicate rocks in Rila, and with carbonates in the western part of the ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seven Rila Lakes
The Seven Rila Lakes (, ) are a group of glacial lakes, situated in the northwestern Rila Mountain in Bulgaria. Situated between 2,100 and 2,500 metres elevation above sea level, they are the most visited group of lakes in Bulgaria. Each lake carries a name associated with its most characteristic feature. The highest one is called ''Salzata'' ("The Tear") due to its clear waters that allow visibility in depth. The next one in height carries the name ''Okoto'' ("The Eye") after its almost perfectly oval form. Okoto is the deepest cirque lake in Bulgaria, with a depth of 37.5 m. Babreka ("The Kidney") is the lake with the steepest shores of the entire group. Bliznaka ("The Twin") is the largest one by area. Trilistnika ("The Trefoil") has an irregular shape and low shores. The shallowest lake is Ribnoto Ezero ("The Fish Lake") and the lowest one is Dolnoto Ezero ("The Lower Lake"), where the waters that flow out of the other lakes are gathered to form the Dzherman River.

Scree
Scree is a collection of broken rock fragments at the base of a cliff or other steep rocky mass that has accumulated through periodic rockfall. Landforms associated with these materials are often called talus deposits. The term ''scree'' is applied both to an unstable steep mountain slope composed of rock fragments and other debris, and to the mixture of rock fragments and debris itself. It is loosely synonymous with talus, material that accumulates at the base of a projecting mass of rock, or talus slope, a landform composed of talus. The term ''scree'' is sometimes used more broadly for any sheet of loose rock fragments mantling a slope, while ''talus'' is used more narrowly for material that accumulates at the base of a cliff or other rocky slope from which it has obviously eroded. Scree is formed by rockfall, which distinguishes it from colluvium. Colluvium is rock fragments or soil deposited by rainwash, sheetwash, or slow downhill creep, usually at the base of gentle ...

Flora Of Albania
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. 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 ...

Plants Described In 1883
Plants are the eukaryotes that form the kingdom Plantae; they are predominantly photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular organism, multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts, mosses, lycophytes, ferns, conif ...

Least-concern Species
A least-concern species is a species that has been evaluated and categorized by the International Union for Conservation of Nature (IUCN) as not being a focus of wildlife conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the " Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15,636) in the IUCN database still use the code "LR/lc", which indicates they have not been re- ...

Style (botany)
In botany, the style of an angiosperm flower is an organ of variable length that connects the ovary to the stigma. The style does not contain ovules; these are limited to the region of the gynoecium (female organs of the flower) called the "ovary". Structure The style is a narrow extension of the ovary, usually pointing upwards, connecting the ovary to the stigmatic papillae. It may be absent in some plants; in this case, it is referred to as a sessile stigma. Styles generally resemble more or less long tubes. The style can be open (with few cells occupying the central part, or even none), featuring a central canal that may be filled with mucilage. Alternatively, the style can be closed (completely filled with cells). Most plants with syncarpous pistils ( monocotyledons and some eudicotys) have open styles, whereas many eudicots and grasses have closed (solid) styles containing specialized secretory tissues, which connect the stigma to the center of the ovary. These tissu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sepals
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 Etymology The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively, the sepals are called the ''calyx'' (plural: calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. The Latin ''calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet'; both words have been used interchangeably in botanical Latin. Description The term ''tepal'' is usually applied when the parts of the perianth are difficult to distinguish, e.g. the petals a ...

Petals
Petals are modified leaves that form an inner whorl surrounding the reproductive parts of flowers. They are often brightly coloured or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually surrounded by an outer whorl of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as '' Rosa'' and ''Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly coloured tepals. Since they inclu ...

Geum Rivale
''Geum rivale'', the water avens, is a flowering plant in the genus ''Geum'' within the family Rosaceae. Other names of the plant are nodding avens, drooping avens, cure-all, water flower and Indian chocolate. It is native to the temperate regions of Europe, Central Asia and parts of North America, where it is known as the purple avens. It grows in bogs and damp meadows, and produces nodding red flowers from May to September. Distribution ''Geum rivale'' is widespread in Europe, particularly in the northern and central parts. It is found throughout the British Isles, the Faroes, Iceland, Scandinavia, the Baltic States, and much of Central Europe (up to elevations of 2400m in the Alps and in the Carpathians). It is absent from the Pannonian Basin and western France; on the Italian Peninsula, it is found in scattered locations in the northern and central Apennines, while on the Iberian Peninsula it is restricted between 1000 m and 2200m in the Cantabrians, Pyrenees, the Iberian ...

Krummholz
''Krummholz'' (, "crooked, bent, twisted" and ''Holz'', "wood") — also called ''knieholz'' ("knee timber") — is a type of stunted, deformed vegetation encountered in the subarctic and subalpine tree line landscapes, shaped by continual exposure to fierce, freezing winds. Under these conditions, trees can survive only where they are sheltered by rock formations or snow cover. As the lower portion of these trees continues to grow, the coverage becomes extremely dense near the ground. In Newfoundland and Labrador, the formation is known as tuckamore. ''Krummholz'' trees are also found on beaches, such as the Oregon coast, where trees can become much taller than their subalpine cousins. The labeling of diverse sets of tree species in different ecological contexts may be problematic. The ecological requirements of ''krummholz'' trees in the Alps, for example, are different from those in the Rockies. The terms ''scrub'' or ''shrubland'' may be more appropriate for some communit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
