Quinchamalium
''Quinchamalium'' is a genus of flowering plant in the family Schoepfiaceae, with a single species ''Quinchamalium chilense'', native to Chile, Argentina, Peru and Bolivia. Depending on the latitude, it can be found from sea level to 3,800 m in altitude. Etymology It is locally called ''quinchamalí''. The word ''kincha'' translates from Quechua as 'hedge of sticks', as often made from dead old quinoa plants (see quincha). Description ''Quinchamalium chilense'' is a herbaceous, hemiparasitic, perennial plant with a rhizome, from which smaller rootlets with haustoria grow. From the rhizome a number of rarely-branching stems grow each year. These can be decumbent (creeping over the ground) or rise to over 2 metres in height. The flowers are produced in a cluster at the end of the stems, they are pentamerous and usually orangey-yellow in colour. It is extremely variable in height and flower size and colour, so much so that at one time 21 species were recognised, but in 201 ...

Schoepfiaceae
Schoepfiaceae is a family of flowering plants recognized in the APG III system of 2009. The family was previously only recognized by few taxonomists; the plants in question usually being assigned to family Olacaceae and Santalaceae. The genus ''Schoepfia'' is, according to molecular studies, more closely related to the families Misodendraceae and Loranthaceae, and to uphold the criteria of monophyly it must be excluded from Olacaceae. Further investigations have also shown that the South American genera ''Arjona'' and '' Quinchamalium'' (previously in the family Santalaceae) are part of this family. Thus the family contains three genera. ''Quinchamalium'' was thought to comprise 21 species in 2015, but this was reduced to a single widespread and morphologically variable species in that year. Christenhusz ''et al''. claimed there was a total of 58 known species in 2016, but for some reason counted 25 species of ''Quinchamalium'' and eight of ''Arjona''. *''Arjona'' Cavanilles (5 o ...

Juan Ignacio Molina
Fr. Juan Ignacio Molina (; (June 24, 1740 – September 12, 1829) was a Chilean Jesuit priest, naturalist, historian, translator, geographer, botanist, ornithologist, and linguist. He is usually referred to as Abate Molina (a form of Abbot Molina), and is also sometimes known by the Italian form of his name, Giovanni Ignazio Molina. He was one of the precursors of the theory of the gradual evolution of species, 44 years before Darwin, who repeatedly quoted him in "The Origin of Species". Biography Early years Molina was born at Guaraculén, a big farm located near Villa Alegre (General Captaincy of Chile), where he lived until he was 5 years old. In the current province of Linares, in the Maule Region of Chile. His parents were Agustín Molina and Francisca González Bruna. From an early age he was attracted to the nature of his environment, and in addition to his school work, he enjoyed observing nature on the family farm, which he visited periodically, alternating with ...

Pollination
Pollination is the transfer of pollen from an anther of a plant to the stigma of a plant, later enabling fertilisation and the production of seeds, most often by an animal or by wind. Pollinating agents can be animals such as insects, birds, and bats; water; wind; and even plants themselves, when self-pollination occurs within a closed flower. Pollination often occurs within a species. When pollination occurs between species, it can produce hybrid offspring in nature and in plant breeding work. In angiosperms, after the pollen grain (gametophyte) has landed on the stigma, it germinates and develops a pollen tube which grows down the style until it reaches an ovary. Its two gametes travel down the tube to where the gametophyte(s) containing the female gametes are held within the carpel. After entering an ovum cell through the micropyle, one male nucleus fuses with the polar bodies to produce the endosperm tissues, while the other fuses with the ovule to produce the embr ...

Patagonia
Patagonia () refers to a geographical region that encompasses the southern end of South America, governed by Argentina and Chile. The region comprises the southern section of the Andes Mountains with lakes, fjords, temperate rainforests, and glaciers in the west and deserts, tablelands and steppes to the east. Patagonia is bounded by the Pacific Ocean on the west, the Atlantic Ocean to the east, and many bodies of water that connect them, such as the Strait of Magellan, the Beagle Channel, and the Drake Passage to the south. The Colorado and Barrancas rivers, which run from the Andes to the Atlantic, are commonly considered the northern limit of Argentine Patagonia. The archipelago of Tierra del Fuego is sometimes included as part of Patagonia. Most geographers and historians locate the northern limit of Chilean Patagonia at Huincul Fault, in Araucanía Region.Manuel Enrique Schilling; Richard WalterCarlson; AndrésTassara; Rommulo Vieira Conceição; Gustavo Walter Bertotto; ...

Poa Obvalata
''Poa'' is a genus of about 570 species of grasses, native to the temperate regions of both hemispheres. Common names include meadow-grass (mainly in Europe and Asia), bluegrass (mainly in North America), tussock (some New Zealand species), and speargrass. ''Poa'' () is Greek for "fodder". ''Poa'' are members of the subfamily Pooideae of the family Poaceae. Bluegrass, which has green leaves, derives its name from the seed heads, which are blue when the plant is allowed to grow to its natural height of two to three feet (0.6 to 0.9 meters). The genus ''Poa'' includes both annual and perennial species. Most are monoecious, but a few are dioecious (separate male and female plants). The leaves are narrow, folded or flat, sometimes bristled, and with the basal sheath flattened or sometimes thickened, with a blunt or hooded apex and membranaceous ligule. Cultivation and uses Many of the species are important pasture plants, used extensively by grazing livestock. Kentucky bluegrass ...

Festuca Scabriuscula
''Festuca'' (fescue) is a genus of flowering plants belonging to the grass family Poaceae (subfamily Pooideae). They are evergreen or herbaceous perennial tufted grasses with a height range of and a cosmopolitan distribution, occurring on every continent except Antarctica. The genus is closely related to ryegrass (''Lolium''), and recent evidence from phylogenetic studies using DNA sequencing of plant mitochondrial DNA shows that the genus lacks monophyly. As a result, plant taxonomists have moved several species, including the forage grasses tall fescue and meadow fescue, from the genus ''Festuca'' into the genus ''Lolium'', or alternatively into the segregate genus ''Schedonorus''. Because the taxonomy is complex, scientists have not determined how many true species belong to the genus, but estimates range from more than 400 to over 640.Darbyshire, S. J. and L. E.

Olax
''Olax'' is a plant genus in the family Olacaceae. The name derives from the Latin, ''olax'' (malodorous), and refers to the unpleasant scent of some of the ''Olax'' species. ''Olax'' is an Old World genus represented by several climbers, some species have leaves and fruits smelling of garlic such as '' Olax subscorpioidea'' and '' Olax gambecola'', seeds of the latter are used as condiments in parts of West Africa. In India '' Olax nana'' is well known as one of the first species to emerge after forest fires, the shoots growing directly from buried roots. Species The type species is O. zeylanica.

Cortaderia
''Cortaderia'' is a genus of South American and Central American plants in the Poaceae grass family. Etymology The common name pampas grass, though strictly referring to ''C. selloana'', is frequently applied to all species in the genus (and sometimes also to species of '' Erianthus'' and ''Saccharum ravennae''). The name of the genus is derived from the Argentine Spanish word ''cortadera'', which in turn refers to the sharp serrations on the leaves. ''Cortaderia jubata'' and '' C. rudiuscula'' produce copious seed asexually. Description The species of ''Cortaderia'' are imposing tall grasses growing 1.5–3 m tall, with graceful white inflorescence plumes. They are in widespread use as ornamental plants. ; Species * ''Cortaderia araucana'' Stapf - Chile, Argentina * ''Cortaderia atacamensis'' (Phil.)

Ovule
In seed plants, the ovule is the structure that gives rise to and contains the female reproductive cells. It consists of three parts: the ''integument'', forming its outer layer, the ''nucellus'' (or remnant of the megasporangium), and the female gametophyte (formed from a haploid megaspore) in its center. The female gametophyte — specifically termed a ''megagametophyte''— is also called the ''embryo sac'' in angiosperms. The megagametophyte produces an egg cell for the purpose of fertilization. The ovule is a small structure present in the ovary. It is attached to the placenta by a stalk called a funicle. The funicle provides nourishment to the ovule. Location within the plant In flowering plants, the ovule is located inside the portion of the flower called the gynoecium. The ovary of the gynoecium produces one or more ovules and ultimately becomes the fruit wall. Ovules are attached to the placenta in the ovary through a stalk-like structure known as a ''funiculus'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chalazal
The chalaza (; from Greek "hailstone"; plural ''chalazas'' or ''chalazae'', ) is a structure inside bird eggs and plant ovules. It attaches or suspends the yolk or nucellus within the larger structure. In animals In the eggs of most birds (not of the reptiles), the chalazae are two spiral bands of tissue that suspend the yolk in the center of the white (the albumen). The function of the chalazae is to hold the yolk in place. In baking, the chalazae are sometimes removed in order to ensure a uniform texture. In plants In plant ovules, the chalaza is located opposite the micropyle opening of the integuments. It is the tissue where the integuments and nucellus are joined. Nutrients from the plant travel through vascular tissue in the funiculus and outer integument through the chalaza into the nucellus. During the development of the embryo sac inside a flowering plant ovule, the three cells at the chalazal end become the antipodal cells. Chalazogamy In most flowering plants, t ...
