Germander
''Teucrium'' is a cosmopolitan genus of flowering plants in the mint family Lamiaceae, commonly known as germanders. Plants in this genus are perennial herbs or shrubs, with branches that are more or less square in cross-section, leaves arranged in opposite pairs, and flowers arranged in thyrses, the corolla with mostly white to cream-coloured, lobed petals. Description Plants in the genus ''Teucrium'' are perennial herbs or shrubs with four-cornered stems, often with simple hairs and sessile glands. The leaves are arranged in opposite pairs, simple or with three leaflets sometimes with lobed or serrated edges. The flowers are arranged in a thyrse, sometimes in a cyme in leaf axils. The flowers have five more or less similar sepals fused at the base, and the corolla is white or cream-coloured with five lobes forming two lips. The upper lip is usually much reduced in size and the lower lip has three lobes, the central lobe usually larger than the side lobes. There are four stam ...

Teucrium Fruticans
''Teucrium fruticans'' (common name tree germander or shrubby germander) is a species of flowering plant in the mint family Lamiaceae, native to the western and central Mediterranean. Growing to tall by wide, it is a spreading evergreen shrub with arching velvety white shoots, glossy aromatic leaves and pale blue flowers in summer. The Latin specific epithet ''fruticans'' means "shrubby" or "bushy". The cultivar 'Azureum', with darker blue flowers, has gained the Royal Horticultural Society's Award of Garden Merit. It is hardy in milder areas, where temperatures do not fall below . It prefers the shelter of a wall, in full sun with neutral or alkaline soil Alkali, or alkaline, soils are clay soils with high Soil pH, pH (greater than 8.5), a poor soil structure and a low infiltration capacity.

Perennial Plant
In horticulture, the term perennial (''wikt:per-#Prefix, per-'' + ''wikt:-ennial#Suffix, -ennial'', "through the year") is used to differentiate a plant from shorter-lived annual plant, annuals and biennial plant, biennials. It has thus been defined as a plant that lives more than 2 years. The term is also loosely used to distinguish plants with little or no woody growth (secondary growth in Tree girth measurement, girth) from trees and shrubs, which are also technically ''perennials''. Notably, it is estimated that 94% of plant species fall under the category of perennials, underscoring the prevalence of plants with lifespans exceeding two years in the botanical world. Perennials (especially small flowering plants) that grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as Herbaceous plant, herbaceous perennials. However, depending on the rigours of the loca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
King Teucer
In Greek mythology, King Teucer (or Teukros) (; Ancient Greek: Τεῦκρος ''Teûkros'') was said to have been the son of the river-god Scamander and the nymph Idaea. Mythology Before the arrival of Dardanus, the land that would eventually be called Dardania (and later still the Troad) was known as Teucria and the inhabitants as Teucrians, after Teucer. According to Virgil, Teucer was originally from Crete but left the island during a great famine with a third of its inhabitants. They settled near the Scamander river, named after Teucer's father, not far from the Rhaetean promontory. However, Dionysius of Halicarnassus states that Teucer had come to the Troad from Attica where he was a chief of the Xypetȇ region. In both cases he ended up in the region which would be known as the Troad. His company was said to have been greatly annoyed by a vast number of mice during their first night in the region. Teucer had previously been directed by an oracle before leaving Crete t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pedanius Dioscorides
Pedanius Dioscorides (, ; 40–90 AD), "the father of pharmacognosy", was a Greek physician, pharmacologist, botanist, and author of (in the original , , both meaning "On Medical Material") , a 5-volume Greek encyclopedic pharmacopeia on herbal medicine and related medicinal substances, that was widely read for more than 1,500 years. For almost two millennia Dioscorides was regarded as the most prominent writer on plants and plant drugs. Life A native of Anazarbus, Cilicia, Asia Minor, Dioscorides likely studied medicine nearby at the school in Tarsus, which had a pharmacological emphasis, and he dedicated his medical books to Laecanius Arius, a medical practitioner there. Though he writes he lived a "soldier's life" or "soldier-like life", his pharmacopeia refers almost solely to plants found in the Greek-speaking eastern Mediterranean, making it likely that he served in campaigns, or travelled in a civilian capacity, less widely as supposed. The name Pedanius is Roman, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Plantarum
' (Latin for "The Species of Plants") is a book by Carl Linnaeus, originally published in 1753, which lists every species of plant known at the time, classified into genus, genera. It is the first work to consistently apply binomial nomenclature, binomial names and was the starting point for the botanical nomenclature, naming of plants. Publication ' was published on 1 May 1753 by Laurentius Salvius in Stockholm, in two volumes. A second edition was published in 1762–1763, and a third edition in 1764, although this "scarcely differed" from the second. Further editions were published after Linnaeus' death in 1778, under the direction of Karl Ludwig Willdenow, the director of the Berlin-Dahlem Botanical Garden and Botanical Museum, Berlin Botanical Garden; the fifth edition was titled "fourth edition" and was published by Willdenow in four volumes, 1798 (1), 1800 (2), 1801 (31), 1803 (32), 1804 (33), 1805 (41), 1806 (42), rather than the dates printed on the volumes themselves. ...

Schizocarp
A schizocarp is a dry fruit that, when mature, splits up into mericarps. There are different definitions: * Any Dry fruits, dry fruit composed of multiple carpels that separate. : Under this definition the mericarps can contain one or more seeds (the mericarps of ''Abutilon'' have two or more seeds) and each mericarp can be either: :* Indehiscent (remaining closed), such as in the carrot and other Umbelliferae or in members of the genus ''Malva'', or :* Dehiscent (splitting open to release the seed), for example members of the genus ''Geranium''. This is similar to what happens with a Capsule (fruit), capsule, but with an extra stage. (In ''Abutilon'', the mericarp is sometimes only partially dehiscent and does not release the seed.) * Any fruit that separates into indehiscent one-seeded segments, such as a loment, ''Malva'', ''Malvastrum'', and ''Sida (plant), Sida''.

Stamen
The stamen (: stamina or stamens) is a part consisting of the male reproductive organs 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 sporangium, microsporangia. Most commonly, anthers are two-lobed (each lobe is termed a locule) and are attached to the filament either at the base or in the middle area of the anther. The sterile (i.e. nonreproductive) tissue between the lobes is called the Connective (botany), 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 size of anthers differs greatly, from a tiny fraction of a millimeter in ''Wolfia'' spp up to five inches (13 centimeters) in ''Canna iridiflora'' and ''Strelitzia nicolai''.

Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 Etymology The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively, the sepals are called the ''calyx'' (plural: calyces), the outermost Whorl (botany), whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. The Latin ''calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet'; both words have been used interchangeably in botanical Latin. Description The term ''tepal'' is usually applied when the parts of the perianth are difficult to distinguish, e. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyme (botany)
In botany, an inflorescence is a group or cluster of flowers arranged on a plant's stem that is composed of a main branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis ( peduncle) and by the timing of its flowering (determinate and indeterminate). Morphologically, an inflorescence is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. General characteristics Inflorescences are described by many different characteristics including how the flowers are arranged on the peduncle, the blooming order of the flowe ...

Gland (botany)
In plants, a gland is defined functionally as a plant structure which secretes one or more products. This may be located on or near the plant surface and secrete externally, or be internal to the plant and secrete into a canal or reservoir. Examples include glandular hairs, nectaries, hydathodes, and the resin canals in Pinus. Notable examples Salt glands of the mangrove The salt glands of mangroves such as '' Acanthus'', '' Aegiceras'', '' Aegialitis'' and ''Avicennia'' are a distinctive multicellular trichome, a glandular hair found on the upper leaf surface and much more densely in the abaxial indumentum. On the upper leaf surface they are sunken in shallow pits, and on the lower surface they occur scattered among long nonglandular hairs composed of three or four cells. Development of the glands resembles that of the nonglandular hairs until the three-celled stage, when the short middle stalk cell appears. The salt gland continues to develop to produce two to four vacu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
