Alrawia
''Alrawia'' is a genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae (also treated as the family Hyacinthaceae). It is native to north-eastern Iraq and Iran. Description Species of ''Alrawia'' grow from bulbs covered with a tunic that is grayish outside and often violet inside. They produce a single flowering stem ( scape); the inflorescence consists of a raceme. Individual flowers are borne on a short stalk ( pedicel) which is turned downwards when the flowers first appear. The tepals are violet with whitish lobe tips and are joined at the base for up to half their length., pp. 4–5 The pedicels lengthen and turn upwards after flowers are fertilized; the black seeds are globular or ovate. Species , the World Checklist of Selected Plant Families recognized two species 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, typicall ...

Scilloideae
Scilloideae (named after the genus ''Scilla'', "squill") is a subfamily of bulbous plants within the family ''Asparagaceae''. Scilloideae is sometimes treated as a separate family Hyacinthaceae, named after the genus ''Hyacinth (plant), Hyacinthus''. Scilloideae or Hyacinthaceae include many familiar garden plants such as ''Hyacinth (plant), Hyacinthus'' (hyacinths), ''Hyacinthoides'' (bluebells), ''Muscari'' (grape hyacinths) and ''Scilla'' and ''Puschkinia'' (squills or scillas). Some are important as cut flowers. Scilloideae are distributed mostly in Mediterranean climates, including South Africa, Central Asia and South America. Their flowers have six tepals and six stamens with a Ovary (botany)#Superior ovary, superior ovary, which previously placed them within the Liliaceae, lily family (Liliaceae), and their leaves are fleshy, mucilage, mucilaginous, and arranged in a rosette (botany), basal rosette.

Pedicel (botany)
In botany, a pedicel is a stem that attaches a single flower to the inflorescence. Such inflorescences are described as ''pedicellate''. The stalk at the base of a leaf is called a petiole. Description Pedicel refers to a structure connecting a single flower to its inflorescence. In the absence of a pedicel, the flowers are described as sessile. Pedicel is also applied to the stem of the infructescence. The word "pedicel" is derived from the Latin ''pediculus'', meaning "little foot". The stem or branch from the main stem of the inflorescence that holds a group of pedicels is called a peduncle. A pedicel may be associated with a bract or bracts.

Alpine House
A greenhouse is a structure that is designed to regulate the temperature and humidity of the environment inside. There are different types of greenhouses, but they all have large areas covered with transparent materials that let sunlight pass and block it as heat. The most common materials used in modern greenhouses for walls and roofs are rigid plastic made of polycarbonate, plastic film made of polyethylene, or glass panes. When the inside of a greenhouse is exposed to sunlight, the temperature increases, providing a sheltered environment for plants to grow even in cold weather. The terms greenhouse, glasshouse, and hothouse are often used interchangeably to refer to buildings used for cultivating plants. The specific term used depends on the material and heating system used in the building. Nowadays, greenhouses are more commonly constructed with a variety of materials, such as wood and polyethylene plastic. A glasshouse, on the other hand, is a traditional type of greenhouse ...

Bulb Frame
In botany, a bulb is a short underground 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 ''Tulipa'' a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brian Mathew
Brian Frederick Mathew MBE, VMH is a British botanist, born in the village of Limpsfield, Surrey, England. His particular area of expertise is bulbous plants, particularly ornamental bulbous plants, although he has contributed to other fields of taxonomy and horticulture. He has authored or co-authored many books on bulbs and bulbous genera which appeal to both botanists and gardeners, as well as specialist monographs on other genera, including ''Daphne'' (with Chris Brickell), ''Lewisia'', and ''Helleborus''. His work has been recognized by the British Royal Horticultural Society and the International Bulb Society. Biography Brian Mathew was born in Limpsfield, a village in Surrey, England. His parents encouraged both Brian and his sister to look after small garden plots allocated to them. He records that as his father was a very successful vegetable gardener, his own interests were more in ornamental plants. An early encounter with '' Helleborus orientalis'' may have laid ...

Species
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. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists 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. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...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) was 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 was available online, allowing searches for the names of families, genera and species, as well as the ability to create checklists. The project traced 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 was completed and other families were 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tepal
A tepal is one of the outer parts of a flower (collectively the perianth). The term is used when these parts cannot easily be classified as either sepals or petals. This may be because the parts of the perianth are undifferentiated (i.e. of very similar appearance), as in ''Magnolia'', or because, although it is possible to distinguish an outer whorl of sepals from an inner whorl of petals, the sepals and petals have similar appearance to one another (as in ''Lilium''). The term was first proposed by Augustin Pyramus de Candolle in 1827 and was constructed by analogy with the terms "petal" and "sepal". (De Candolle used the term ''perigonium'' or ''perigone'' for the tepals collectively; today, this term is used as a synonym for ''perianth''.) p. 39. Origin Undifferentiated tepals are believed to be the ancestral condition in flowering plants. For example, ''Amborella'', which is thought to have separated earliest in the evolution of flowering plants, has flowers with undiffer ...
