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 ...

Acaena Novae-zelandiae
''Acaena novae-zelandiae'', commonly known as red bidibid, bidgee widgee, buzzy and piri-piri bur, is a small herbaceous, prostrate perennial, native to New Zealand, Australia and New Guinea, of the family Rosaceae. Description ''Acaena novae-zelandiae'' is a small herbaceous perennial. It is stoloniferous with prostrate stems of 1.5 – 2 mm diameter. Damage to stolons encourages new shoots to be produced. It has imparipinnate leaves, with 9–15 toothed, oblong leaflets, which are approximately 2 –11 cm long. The adaxial surface of the leaves is dark green and shiny, and the abaxial surface is hairy and glaucous green in colouration. The rachis of the leaves is often red. The scape is 10 – 15 cm long and bears a globular, terminal inflorescence, of 20 – 25 mm diameter, with 70 – 100 flowers. The flowers lack petals and can range in colour from green to white or purple. The flowers are wind pollinated. Each flower produces one achene, bearing ...

Acaena Microphylla
''Acaena microphylla'', the bidibid or piripiri, and outside New Zealand, New Zealand-bur, is a small herbaceous, prostrate perennial flowering plant in the rose family Rosaceae, native to both the North and South Islands of New Zealand. There are two varieties: *''Acaena microphylla'' var. ''pauciglochidiata'' Bitter *''Acaena microphylla'' Hook.f var. ''microphylla'' There are no synonyms. Description Hooker describes it as "a very small and glabrous species; the leaflets not 1/4 in. long. ''Capitula'' very large for the size of the plant, upwards of an inch across, including the spines, which are not barbate, and distinguish it as a species." Taxonomy and naming ''Acaena microphylla'' was first formally described in 1852 by Joseph Dalton Hooker. The genus name ''Acaena'' is derived from the ancient Greek word ''akaina'', meaning "thorn" or "spine", referring to the spiny calyx of many species of ''Acaena''. The specific epithet ''microphylla'' derives from the Greek wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acaena Alpina
''Acaena alpina'' is a perennial shrub of the genus ''Acaena'' known for its hardiness and durability. ''A. alpina'' is found throughout central Chile and Argentina. It can withstand a wide range of climates, including that of the Andes, where it is commonly found. ''A.'' ''alpina'' can withstand both hot and cold temperatures as well as wet and dry seasons, though it preferentially grows at high altitudes. ''A. alpina'' was originally typified by Eduard Friedrich Poeppig and Wilhelm Gerhard Walpers in 1843. Habitat and distribution ''Acaena alpina'' is a shrub found along the mountain ranges of South America. ''A. alpina'' is mainly distributed throughout Chile and Argentina, specifically along the Andes mountain range. This organism is also found along vegetation belts in South America, specifically along the 33rd parallel south and most commonly at an elevation of 2100 m to 2500 m. In Chile, the range of ''A. alpina'' spans Regions Five through Nine, from north Valparaíso to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acaena Antarctica
''Acaena antarctica'' is a small herbaceous plant in the Rosaceae family native to Argentina, Chile and the Falkland Islands. Taxonomy and naming ''Acaena antarctica'' was first formally described in 1846 by Joseph Dalton Hooker. Kew holds specimens collected by Hooker from Hermite Island, Cape Horn on the Ross expedition. The genus name ''Acaena'' is derived from the Ancient Greek word ''akaina'' meaning "thorn" or "spine", referring to the spiny calyx of many species of ''Acaena''. The specific epithet, ''antarctica'', derives from the Greek (''anti'', "opposite" and ''arktos'', "bear") and designates the place opposite the constellations of the Great and the Little Bear, thus describing the species as coming from south of the South Pole circle.

Flower
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) resulting from cross-pollination or allow selfing (fusion of sperm and egg from the same flower) when self-pollination occurs. There are two types of pollination: self-pollination and cross-pollination. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is when pollen is transferred from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happens in flowers where the stamen and carpel mature at the same time, and are positi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
