Acis Valentina
''Acis valentina'' is a species of bulbous flowering plant in the family Amaryllidaceae, native to eastern Spain. Its white flowers appear in autumn. It can be grown as an ornamental bulb, but may need protection from hard frost. Description ''Acis valentina'' is usually no more than 12 cm tall. It flowers in the autumn, the thread-like leaves appearing after the flowers. Flowers may be solitary or in a group of two or three. The flower has six milky white tepals, 8–14 mm long, each with a sharp point at the apex (at least in the outer three). ''Acis valentina'' resembles the spring-flowering ''Acis nicaeense'' in several ways, including possessing a six-lobed disc at the base of the ovary. Taxonomy ''Acis valentina'' was first described in 1914 by Carlos Pau, as ''Leucojum valentinum''. It was transferred to the genus ''Acis (plant), Acis'', along with other species of ''Leucojum'', in 2004. Its nearest relative appears to be ''Acis ionica'', found in the Balkans. ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acis Ionica
''Acis ionica'' is a species of flowering plant in the family Amaryllidaceae, native from south-western Albania to western Greece. It was initially confused with what is now ''Acis valentina'', a species found in Spain near Valencia. Description ''Acis ionica'' is a bulbous plant with narrow leaves, 12–22 cm long but only 2–3 mm wide. The leaves appear after flowering, which is in the autumn. The flowering stalk ( scape) is usually 8–20 cm tall, with an inflorescence composed of two to four flowers, occasionally only one or as many as six. The inflorescence is subtended by two spathes, usually extending to below the level of the highest flower. Each flower opens widely and is borne on a stem (pedicel) about 16–28 mm long. The six tepals are white, generally 9–13 mm long. The outer three tepals have pointed tips. The pedicel lengthens after flowering. The black seeds are about 3 mm long. Taxonomy ''Acis'' species were at one time placed i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

World Checklist Of Selected Plant Families
The World Checklist of Selected Plant Families (usually abbreviated to WCSP) is an "international collaborative programme that provides the latest peer reviewed and published opinions on the accepted scientific names and synonyms of selected plant families." Maintained by the Royal Botanic Gardens, Kew, it is available online, allowing searches for the names of families, genera and species, as well as the ability to create checklists. The project traces its history to work done in the 1990s by Kew researcher Rafaël Govaerts on a checklist of the genus '' Quercus''. Influenced by the Global Strategy for Plant Conservation, the project expanded. , 173 families of seed plants were included. Coverage of monocotyledon families is complete; other families are being added. There is a complementary project called the International Plant Names Index (IPNI), in which Kew is also involved. The IPNI aims to provide details of publication and does not aim to determine which are accepted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Plant Names Index
The International Plant Names Index (IPNI) describes itself as "a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes." Coverage of plant names is best at the rank of species and genus. It includes basic bibliographical details associated with the names. Its goals include eliminating the need for repeated reference to primary sources for basic bibliographic information about plant names. The IPNI also maintains a list of standardized author abbreviations. These were initially based on Brummitt & Powell (1992), but new names and abbreviations are continually added. Description IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew ( Index Kewensis), The Harvard University Herbaria (Gray Herbarium Index), and the Australian National Herbarium ( APNI). The IPNI database is a collection of the names registered by the three cooperating institutions and they work towards standardizing the information. The st ...

Alpine House
A greenhouse (also called a glasshouse, or, if with sufficient heating, a hothouse) is a structure with walls and roof made chiefly of transparent material, such as glass, in which plants requiring regulated climatic conditions are grown.These structures range in size from small sheds to industrial-sized buildings. A miniature greenhouse is known as a cold frame. The interior of a greenhouse exposed to sunlight becomes significantly warmer than the external temperature, protecting its contents in cold weather. Many commercial glass greenhouses or hothouses are high tech production facilities for vegetables, flowers or fruits. The glass greenhouses are filled with equipment including screening installations, heating, cooling, and lighting, and may be controlled by a computer to optimize conditions for plant growth. Different techniques are then used to manage growing conditions, including air temperature, relative humidity and vapour-pressure deficit, in order to provide the opt ...

Valencia
Valencia ( va, València) is the capital of the autonomous community of Valencia and the third-most populated municipality in Spain, with 791,413 inhabitants. It is also the capital of the province of the same name. The wider urban area also comprising the neighbouring municipalities has a population of around 1.6 million, constituting one of the major urban areas on the European side of the Mediterranean Sea. It is located on the banks of the Turia, on the east coast of the Iberian Peninsula, at the Gulf of Valencia, north of the Albufera lagoon. Valencia was founded as a Roman colony in 138 BC. Islamic rule and acculturation ensued in the 8th century, together with the introduction of new irrigation systems and crops. Aragonese Christian conquest took place in 1238, and so the city became the capital of the Kingdom of Valencia. The city's population thrived in the 15th century, owing to trade with the rest of the Iberian Peninsula, Italian ports and other loca ...

Leucojum
''Leucojum'' is a small genus of bulbous plants native to Eurasia belonging to the Amaryllis family, subfamily Amaryllidoideae. As currently circumscribed, the genus includes only two known species, most former species having been moved into the genus '' Acis''. Both genera are known as snowflakes. ''Leucojum'' is a compound of Greek λευκος, ''leukos'' "white" and ἰόν, ''ion'' "violet". The spelling ''Leucoium'' is also used. Other common names include snowbell, dewdrop, and St. Agnes' flower. Description Until 2004, the genus ''Leucojum'' was treated as including species now placed in ''Acis''. ''Leucojum'' when narrowly circumscribed consists of only two species, '' Leucojum aestivum'' and '' Leucojum vernum''. Compared to ''Acis'', ''Leucojum'' has hollow rather than solid flower stalks ( scapes), white flowers with green or yellow marks on both the inner and outer three tepals, flower stems (pedicels) at least as long as the spathes enclosing the infloresc ...

Bulb
In botany, a bulb is structurally a short stem with fleshy leaves or leaf basesBell, A.D. 1997. ''Plant form: an illustrated guide to flowering plant morphology''. Oxford University Press, Oxford, U.K. that function as food storage organs during dormancy. (In gardening, plants with other kinds of storage organ are also called "ornamental bulbous plants" or just "bulbs".) Description The bulb's leaf bases, also known as scales, generally do not support leaves, but contain food reserves to enable the plant to survive adverse conditions. At the center of the bulb is a vegetative growing point or an unexpanded flowering shoot. The base is formed by a reduced stem, and plant growth occurs from this basal plate. Roots emerge from the underside of the base, and new stems and leaves from the upper side. Tunicate bulbs have dry, membranous outer scales that protect the continuous lamina of fleshy scales. Species in the genera ''Allium'', ''Hippeastrum'', ''Narcissus'', and '' Tuli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acis (plant)
''Acis '' is a genus of perennial, herbaceous and bulbous plants in the amaryllis family ( Amaryllidaceae, subfamily Amaryllidoideae). The genus consists of nine species distributed in Europe and Northern Africa. ''Acis'' was previously included in ''Leucojum''; both genera are known as snowflakes. Description ''Acis'' species are perennial bulbous plants. The flowers have six equally sized tepals, unlike the related genus '' Galanthus'' (snowdrops) in which the inner three tepals are shorter than the outer three. The tepals are unmarked, differing in this respect from ''Leucojum''. Most species have white tepals, although those of ''Acis rosea'' are pale pink. ''Acis'' species are relatively short, up to in '' Acis autumnalis'' and in '' Acis tingitana''. The leaves are narrow; very narrow (filiform) in '' Acis trichophylla''. The flower stalks (scapes) are solid. Taxonomy ''Acis'' was first differentiated from the genus ''Leucojum'' by Richard Anthony Salisbury in '' The P ...
