Cotula
''Cotula'' is a genus of flowering plant in the sunflower family. It includes plants known generally as water buttons or buttonweeds. The species within this genus can vary extensively in their habit, leaf division, involucre, receptacle and achenes. This makes it difficult to define them by comparing their morphology. The genus can only be defined by looking at the corollas of their flowers. Most are disciform (lacking ray florets). These corollas may be tubular, reduced or even absent. Another characteristic is their solitary heads growing on a peduncle. Taxonomy ''Cotula'' is the largest genus found in the Southern Hemisphere of the tribe Anthemideae. This genus was first mentioned by Carl Linnaeus, who described four species in his first edition (1753) of '' Species Plantarum''. In 1867 the genus was subdivided by George BenthamBentham, G., 1867: "Flora Australiensis", Vol. 3. Reeve, London. into three sections. Since his account, only a few changes have been made but ...

Cotula Coronopifolia
The small marsh flower ''Cotula coronopifolia'' bears the common names brass buttons, golden buttons, and buttonweed. The flower heads are bright yellow discoid heads that look like thick buttons. Individual plants spread stems along the ground and send up the knobby flowers at intervals. The plant is native to southern Africa, as well as New Zealand, but it has been introduced to other parts of the world (Europe, North + South America, etc.). Brass buttons are common plants that occupy a specialized ecological niche. They prefer muddy, anoxic wetlands and brackish water. They are very salt-tolerant. The plant has fat, fleshy leaves that store water during times of saline inundation. The reddish stems and green, blade-shaped leaves are coated with a shiny cuticle to retain moisture. It can also be found in the wetter patches in vernal pool ecosystems. Brass buttons are common along beaches, salt marshes, and estuaries from California to Washington. It has been present in the Brit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cotula Alpina
''Cotula alpina'', also known as the alpine cotula, is a perennial herb in the family Asteraceae. It is a small flowering plant that forms ground covering mats and is well adapted to alpine environments. Description Alpine cotula has flat glabrous light-green leaves that are pinnately divided almost to the midrib.Kirkpatrick, J.

(2004) Tasmania's Natural Flora. Ulverstone, TAS: Tasmania's Natural Flora Editorial Committee.

Leptinella
''Leptinella'' is a genus of alpine flowering plant in the family Asteraceae, comprising 33 species, distributed in New Guinea, Australia, New Zealand, South Africa, and South America. Many of the species are endemic to New Zealand. For over 100 years, ''Leptinella'' species were considered part of the genus ''Cotula'', but the genus ''Leptinella'' was reinstated by Lloyd & Webb in 1987. They determined that all species of ''Leptinella'' are distinguished from those of the other two sections of ''Cotula'', and other Anthemideae, by the conspicuous "inflated" corollas of the female florets and by chromosome numbers based on x = 26 where known. ''Leptinella squalida'' 'Platt's Black' is a form cultivated as a garden plant, and is used for ground cover Groundcover or ground cover is any plant that grows over an area of ground. Groundcover provides protection of the topsoil from erosion and drought. In an ecosystem, the ground cover forms the layer of vegetation below the shru ...

Anthemideae
Anthemideae is a tribe of flowering plants in the family, Asteraceae, and the subfamily Asteroideae. They are distributed worldwide with concentrations in central Asia, the Mediterranean Basin, and southern Africa.Oberprieler, C., et al. (2007) A new subtribal classification of the tribe Anthemideae (Compositae). ''Willdenowia'' 37(1): 89–114. Most species of plant known as chamomile belong to genera of this tribe. As of 2006 there were about 1800 species classified in 111 genera. In 2007 the tribe was divided into 14 subtribes, including Glebionidinae, the source of hybrid garden marguerites.

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...
