Johann Friedrich Adam
Johann Friedrich Adam, later called Michael Friedrich Adams (1780 in Moscow – 1 March 1838, in Vereya) was a botanist from St. Petersburg, Russia. He studied from 1795–1796 in the medical school of St. Petersburg. In the years 1800–1802 he traveled across Transcaucasia in the entourage of Count Apollo Mussin-Pushkin (1760–1805). In 1805, he was part of a scientific team attached to the unsuccessful diplomatic mission of Count Yury Golovkin to China. After the failure of the mission, he and many of the other scientists stayed on in Siberia to pursue their researches. In 1806, while in Yakutsk, he heard about an intact woolly mammoth carcass near the mouth of the Lena River. He hastily arranged an expedition to the location where he was able to recover most of the skeleton, skin, and almost forty pounds of hair. At the time, and for almost a century after, this was the most complete mammoth known. He returned to St. Petersburg with his prize. The skeleton is now on d ...

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains '' microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea''). The androecium in va ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Western Asia
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is '' fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules ...

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 '' Hyacinthus''. Scilloideae or Hyacinthaceae include many familiar garden plants such as '' 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 superior ovary, which previously placed them within the lily family (Liliaceae), and their leaves are fleshy, mucilaginous, and arranged in a basal rosette. The Scilloideae, like most lily-like monocots, were at one time placed in a very broadly defined lily family (Liliaceae). The subfamily is recognized in modern classi ...

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 accep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornamental Bulbous Plant
Ornamental bulbous plants, often called ornamental bulbs or just bulbs in gardening and horticulture, are herbaceous perennials grown for ornamental purposes, which have underground or near ground storage organs. Botanists distinguish between true bulbs, corms, rhizomes, tubers and tuberous roots, any of which may be termed "bulbs" in horticulture. Bulb species usually lose their upper parts during adverse conditions such as summer drought and heat or winter cold. The bulb's storage organs contain moisture and nutrients that are used to survive these adverse conditions in a dormant state. When conditions become favourable the reserves sustain a new growth cycle. In addition, bulbs permit vegetative or asexual multiplication in these species. Ornamental bulbs are used in parks and gardens and as cut flowers. Terminology The word "bulb" has a somewhat different meaning to botanists than it does to gardeners and horticulturalists. In gardening, a "bulb" is a plant's undergro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Puschkinia Scilloides-3
''Puschkinia'' is a genus of four known species of bulbous perennials in the family Asparagaceae, subfamily Scilloideae. It is native to the Caucasus and the Middle East. ''Puschkinia scilloides'' is grown as an ornamental bulbous plant. Description The leaves are green, strap-like, and grow in pairs. The flowers are borne in early spring in racemes up to about high. The six tepals are joined at the base to form a tube to about half their length. Like members of the former genus ''Chionodoxa'' (now a section of ''Scilla''), the bases of the stamens are flattened and closely clustered in the middle of the flower; however, unlike ''Chionodoxa'', they are joined to form a cup or corona. In the related genus ''Scilla'' (squills), the stamens are not joined together. Seeds are borne in three-parted capsules. After the seed ripens in early summer, the plants become dormant until the next spring. Taxonomy The genus ''Puschkinia'' was erected by Johann Friedrich Adam in 1805. It is n ...

Stigma (botany)
The stigma () is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower. Description The stigma, together with the style and ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of , the cells of which are receptive to pollen. These may be restricted to the apex of the style or, especially in wind pollinated species, cover a wide surface. The stigma receives pollen and it is on the stigma that the pollen grain germinates. Often sticky, the stigma is adapted in various ways to catch and trap pollen with various hairs, flaps, or sculpturings. The pollen may be captured from the air (wind-borne pollen, anemophily), from visiting insects or other animals (biotic pollination), or in rare cases from surrounding water ( hydrophily). Stigma can vary from long and sle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 '' ... [...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 undi ...
