Acaena Magellanica
''Acaena magellanica'', commonly called buzzy burr or greater burnet, is a species of flowering plant whose range includes the southern tip of South America and many subantarctic islands. Description ''Acaena magellanica'' is a perennial, mat-forming plant with creeping stems, up to high. The leaves are oblong to linear-lanceolate, with 5 to 10 pairs of ovate leaflets. The flower heads are globular and grow on wiry stems well clear of the foliage. They are followed by brown, prickly seed heads; the seeds have small hooks which enables them to adhere to clothing, feathers or fur. Distribution and habitat The species is native to the southern part of South America. Its range includes Argentina, Chile and various sub-Antarctic islands including the Falkland Islands, the Kerguelen Islands, the Prince Edward Islands, Crozet Islands, South Georgia and the South Sandwich Islands and the Heard Island and McDonald Islands. Its typical habitat is damp places such as the edge of bogs, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean-Baptiste Lamarck
Jean-Baptiste Pierre Antoine de Monet, chevalier de Lamarck (1 August 1744 – 18 December 1829), often known simply as Lamarck (; ), was a French naturalist, biologist, academic, and soldier. He was an early proponent of the idea that biological evolution occurred and proceeded in accordance with Naturalism (philosophy), natural laws. Lamarck fought in the Seven Years' War against Prussia, and was awarded a commission for bravery on the battlefield. Posted to Monaco, Lamarck became interested in natural history and resolved to study medicine.#Packard, Packard (1901), p. 15. He retired from the army after being injured in 1766, and returned to his medical studies. Lamarck developed a particular interest in botany, and later, after he published the three-volume work ''Flore françoise'' (1778), he gained membership of the French Academy of Sciences in 1779. Lamarck became involved in the Jardin des Plantes and was appointed to the Chair of Botany in 1788. When the French Nationa ...

Southern Indian Ocean Islands Tundra
The Southern Indian Ocean Islands tundra is a tundra ecoregion that includes several subantarctic islands in the southern Indian Ocean. Location and description The ecoregion stretches from Prince Edward Islands in the west, past the Crozet Islands to the Kerguelen Islands 1500 km to the east, and includes the active volcano Heard Island and the nearby McDonald Islands. Flora These rocky islands support a variety of plant life, such as tussock grasses, that has adapted to the snowy and icy conditions. There are a number of endemic plant species including ''Poa cookii'' grass and the Kerguelen cabbage ('' Pringlea antiscorbutica''), historically a source of vitamin C for sailors, is found on all the islands, not only the Kerguelens. There are also a number of endemic lichens and liverworts. Fauna The islands are home to birds and insects such as butterflies, moths, weevils, and spiders as well as wildlife typical of the southern oceans such as penguins, seals and s ...

Flora Of The Subantarctic Islands
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 Phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acaena
''Acaena'' is a genus of about 60 species of mainly evergreen, creeping herbaceous perennial plants and subshrubs in the family Rosaceae, native mainly to the Southern Hemisphere, notably New Zealand, Australia and South America, but with a few species extending into the Northern Hemisphere, north to Hawaii ('' A. exigua'') and California ('' A. pinnatifida''). The leaves are alternate, long, and pinnate or nearly so, with 7–21 leaflets. The flowers are produced in a tight globose nflorescence in diameter, with no petals. The fruit is also a dense ball of many seeds; in many (but not all) species the seeds bear a barbed arrowhead point, the seedhead forming a burr which attaches itself to animal fur or feathers for dispersal. Several ''Acaena'' species in New Zealand are known by the common name bidibid. The word is written variously ''bidi-bidi'', ''biddy-biddy'', ''biddi-biddi'', ''biddi-bid'' and a number of other variations. These names are the English rendition of the ...

Taraxacum Officinale
''Taraxacum officinale'', the dandelion or common dandelion, is a flowering herbaceous perennial plant of the dandelion genus in the family Asteraceae (syn. Compositae). The common dandelion is well known for its yellow flower heads that turn into round balls of many silver-tufted fruits that disperse in the wind. These balls are usually called "clocks" in both British and American English. The name "blowball" is also used. The common dandelion grows in temperate regions of the world in areas with moist soils. It is most often considered a weed, especially in lawns and along roadsides, but the leaves, flowers, and roots are sometimes used in herbal medicine and as food. Description ''Taraxacum officinale'' grows from (generally unbranched) taproots and produces several hollow, leafless flower stems that are typically tall, but sometimes up to tall. The stems can be tinted purplish, they are upright or lax, and produce flower heads that are held as tall or taller than the ...

Cerastium Fontanum
''Cerastium fontanum'', also called mouse-ear chickweed, common mouse-ear, or starweed, is a species of mat-forming perennial or, rarely, annual plant. It is native to Europe but introduced elsewhere. Its identifying characteristics are tear-shaped leaves growing opposite one another in a star pattern, hairy leaves, and small white flowers. Mouse-ear chickweed typically grows to 4"-8" tall and spreads horizontally along the ground via the formation of roots wherever the stem falls over and contacts the ground. Description ''Cerastium fontanum'' is a low growing plant covered with small hairs which are not sticky, that is, without glandular tips. The erect flowering stems up to long and leaves, opposite, up to long without stalks. It has prostrate branches which do not bear flowers. The petals are shorter than the sepals or a little longer and are deeply divided. The flowers have 10 stamens with 5 styles.Calpham, A.R., Tutin, T.G. and Warburg, E.F. 1968. ''Excursion Flora of ...

Poa Annua
''Poa annua'', or annual meadow grass (known in America more commonly as annual bluegrass or simply poa), is a widespread low-growing turfgrass in temperate climates. Notwithstanding the reference to annual plant in its name, perennial bio-types do exist. This grass may have originated as a hybrid between ''Poa supina'' and '' Poa infirma''. Description It has a slightly creeping, fibrous, rootstock. The stem grows from 15–25 cm (6-10 in.) high. It is slightly flattened, due to being folded rather than rolled. The panicle is open and triangular shaped, 5 to 7.5 cm (2 to 3 in.) long. The spikelets are stalked, awnless, 1 to 2 cm (3/8 to 3/4 in.) long when flowering, and loosely arranged on delicate paired or spreading branches. Sometimes they are tinged purple. The vivid green leaves are short and blunt at the tips, shaped like the prow of a small canoe. They are soft and drooping. Long sheaths clasp the stem. The leaves are smooth above and below, with fin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Rabbit
The European rabbit (''Oryctolagus cuniculus'') or coney is a species of rabbit native to the Iberian Peninsula (including Spain, Portugal, and southwestern France), western France, and the northern Atlas Mountains in northwest Africa. It has been widely introduced elsewhere, often with devastating effects on local biodiversity. Its decline in its native range due to myxomatosis, rabbit calicivirus, overhunting and habitat loss has caused the decline of the Iberian lynx (''Lynx pardinus'') and Spanish imperial eagle (''Aquila adalberti''). It is known as an invasive species because it has been introduced to countries on all continents with the exception of Antarctica, and has caused many problems within the environment and ecosystems; in particular, European rabbits in Australia have had a devastating impact, due in part to the lack of natural predators there. The European rabbit is well known for digging networks of burrows, called warrens, where it spends most of its tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forb
A forb or phorb is an herbaceous flowering plant that is not a graminoid (grass, sedge, or rush). The term is used in biology and in vegetation ecology, especially in relation to grasslands and understory. Typically these are dicots without woody stems. Etymology The word "forb" is derived from Greek ''phorbḗ'' (), meaning "pasture" or "fodder". The Hellenic spelling "phorb" is sometimes used, and in older usage this sometimes includes graminids and other plants currently not regarded as forbs. Guilds Forbs are members of a guilda group of plant species with broadly similar growth form. In certain contexts in ecology, guild membership may often be more important than the taxonomic relationships between organisms. In informal classification In addition to its use in ecology, the term "forb" may be used for subdividing popular guides to wildflowers, distinguishing them from other categories such as grasses, sedges, shrubs, and trees. Some examples of forbs are clovers, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tortula Robusta
''Tortula'' is a genus of mosses in the family Pottiaceae. Species There are different classifications for the species included in the genus. The delimitation of genus Tortula is problematic and was subject to a number of alterations in the past. Some species that were earlier placed under ''Desmatodon'', '' Phascum'' and '' Pottia'' have been made part of genus ''Tortula'', while other species that had been formerly placed in this genus became part of '' Hennediella,'' '' Microbryum'' and '' Syntrichia''. The rearrangement of the genus followed new studies in gametophyte characteristics.Wolfgang Frey, Michael Stech, Eberhard Fischer: ''Bryophytes and Seedless Vascular Plants'' (= Syllabus of Plant Families. 3). 13th edition. Borntraeger, Berlin 2009, , pp. 182, 183 * '' Tortula acaulon'' (With.) R. H. Zander ** '' Tortula acaulon var. pilifera'' (Schreb. ex Hedw.) R.H.
