Thymus (plant)
The genus ''Thymus'' ( ; thymes) contains about 350 species of aromatic perennial plant, perennial herbaceous plants and subshrubs in the family Lamiaceae. It is native to the Old World. Several members of the genus are cultivated as culinary herbs or ornamentals, when they are also called thyme after its best-known species, ''Thymus vulgaris'' or common thyme. Description The plants grow up to tall. The stems tend to be narrow or even wiry. The leaves are evergreen in most species, arranged in opposite pairs, oval, entire, and small, long, and usually aromatic. Thyme flowers are in dense terminal heads with an uneven sepal, calyx, with the upper lip three-lobed, and are yellow, white, or purple. Classification A considerable amount of confusion has existed in the naming of thymes. Many nurseries use common names rather than binomial names, which can lead to mix-ups. For example ''golden thyme'', ''lemon thyme'', and ''creeping thyme'' are all common names for more than one c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thymus Amurensis
The thymus (: thymuses or thymi) is a specialized primary lymphoid organ of the immune system. Within the thymus, T cells mature. T cells are critical to the adaptive immune system, where the body adapts to specific foreign invaders. The thymus is located in the upper front part of the chest, in the anterior superior mediastinum, behind the sternum, and in front of the heart. It is made up of two lobes, each consisting of a central medulla and an outer cortex, surrounded by a capsule. The thymus is made up of immature T cells called thymocytes, as well as lining cells called epithelial cells which help the thymocytes develop. T cells that successfully develop react appropriately with MHC immune receptors of the body (called ''positive selection'') and not against proteins of the body (called ''negative selection''). The thymus is the largest and most active during the neonatal and pre-adolescent periods. By the early teens, the thymus begins to decrease in size and activity ...

Thymus Citriodorus
''Thymus citriodorus'', the lemon thyme or citrus thyme, is a lemon-scented evergreen mat-forming perennial plant in the family Lamiaceae. There has been a great amount of confusion over the plant's correct name and origin. Recent DNA analysis suggests that it is not a hybrid or cross, but a distinct species as it was first described in 1811. An analysis in a different study clustered ''Thymus citriodorus'' together with Thymus vulgaris, which is considered as one of its parent species (see below). ''T. citriodorus'' is an evergreen sub-shrub, growing to in height by in spread. It prefers full sun and well draining soil. The bloom period is mid to late summer, with pink to lavender flowers that are a nectar source for bees and butterflies.PFAF: taxonomy/treatment Accessed 12.1.2011 Uses ...

Thymus Carnosus
''Thymus carnosus'' is a species of flowering plant in the family Lamiaceae. It is native to southern Portugal and Spain. It is a woody, upright perennial In horticulture, the term perennial ('' per-'' + '' -ennial'', "through the year") is used to differentiate a plant from shorter-lived annuals and biennials. It has thus been defined as a plant that lives more than 2 years. The term is also ... to tall, with clusters of fleshy, oval, light green to grey-green leaves, furry on their undersides. Its white, lilac, or pink flowers are borne on spikes and are protected by oval green bracts. The plant is hardy from USDA Zones 7–11.Griffiths, Mark. ''Index of Garden Plants.''

Thymus Capitatus
''Thymus capitatus'' is a compact, woody perennial native to Mediterranean Europe and Turkey, more commonly known as conehead thyme, Persian-hyssop and Spanish oregano. It is also known under the name ''Thymbra capitata''. Description The plant has rising stems and narrow, fleshy, oil-gland-dotted green leaves that reach a length of . The pink, -long flowers are held in cone-shaped clusters at the ends of their stems in mid to late summer; they are protected by overlapping, -long, red-tinged bracts, edged in tiny hairs. In Eurasia, a species of leafless parasitic dodder ('' Cuscuta epithymum'') would often attach itself to the conehead thyme (''Thymus capitatus''), taking on the plant's pungency and from whence it also derived its host's Arabic name, ''al-ṣaʿitrah''. -- () ''Thymus capitatus'' is hardy from USDA Zones 7–10. In Israel, the plant ''Thymus capitatus'' has protected status, making it a criminal offence to harvest it.Avi Shmida, ''MAPA's Dictionary of Plants a ...

Thymus Caespititius
''Thymus caespititius'' is a dwarf, aromatic mat-forming groundcover shrub. It is native to oceanic areas in the Iberian Peninsula (northwest Portugal and northwest Spain) and the Atlantic archipelagos of the Azores and Madeira. The plant has narrow, spatula-shaped, smooth leaves to long, fringed with tiny hairs. The rose, lilac or white flowers are borne in small, flattened mat-hugging heads from late spring to summer. Cultivation ''Thymus caespititius'', grown as an ornamental plant, and is hardy down to USDA Zone 7. The cultivar ''Thymus caespititius'' 'Aureus' has narrow, light gold leaves.Griffiths, Mark.
