Ericoideae
Ericoideae is a subfamily of Ericaceae, containing nineteen genera, and 1,790 species, the largest of which is ''Rhododendron'', followed by Erica. The Ericoideae bear spiral leaves with flat laminae. The pedicel is articulated and the flowers are pendulous or erect, and monosymmetric, with an abaxial median sepal. The carpels are free and the anthers lack appendages. The capsule is septicidal.

Ericaceae
The Ericaceae are a family of flowering plants, commonly known as the heath or heather family, found most commonly in acidic and infertile growing conditions. The family is large, with c.4250 known species spread across 124 genera, making it the 14th most species-rich family of flowering plants. The many well known and economically important members of the Ericaceae include the cranberry, blueberry, huckleberry, rhododendron (including azaleas), and various common heaths and heathers (''Erica'', ''Cassiope'', ''Daboecia'', and ''Calluna'' for example). Description The Ericaceae contain a morphologically diverse range of taxa, including herbs, dwarf shrubs, shrubs, and trees. Their leaves are usually evergreen, alternate or whorled, simple and without stipules. Their flowers are hermaphrodite and show considerable variability. The petals are often fused (sympetalous) with shapes ranging from narrowly tubular to funnelform or widely urn-shaped. The corollas are usually ra ...

Rhododendron
''Rhododendron'' (; from Ancient Greek ''rhódon'' "rose" and ''déndron'' "tree") is a very large genus of about 1,024 species of woody plants in the heath family (Ericaceae). They can be either evergreen or deciduous. Most species are native to eastern Asia and the Himalayan region, but smaller numbers occur elsewhere in Asia, and in North America, Europe and Australia. It is the national flower of Nepal, the state flower of Washington and West Virginia in the United States, the state flower of Nagaland in India, the provincial flower of Jiangxi in China and the state tree of Sikkim and Uttarakhand in India. Most species have brightly colored flowers which bloom from late winter through to early summer. Azaleas make up two subgenera of ''Rhododendron''. They are distinguished from "true" rhododendrons by having only five anthers per flower. Species Description ''Rhododendron'' is a genus of shrubs and small to (rarely) large trees, the smallest species growing to t ...

Bryanthus
''Bryanthus'' is a monotypic genus of ornamental plant in the flowering plant family Ericaceae, with the sole species ''Bryanthus musciformis'', native to Japan, Kamchatka, and the Kuril Islands. The genus was created in 1769. In 2012, the new tribe Bryantheae was proposed based on genetic analysis, containing the genera ''Bryanthus'' and ''Ledothamnus''. Former species Species that have been placed in ''Bryanthus'' include: * ''Bryanthus aleuticus'' (Spreng.) A.Gray, synonym of ''Phyllodoce aleutica'' * ''Bryanthus empetriformis'' , synonym of ''Phyllodoce empetriformis ''Phyllodoce empetriformis'', the pink mountain-heather or pink mountain-heath, is found in mountainous regions of western North America in the Northwestern United States and Western Canada.

Ceratiola
''Ceratiola'' is a genus of flowering plants with a single species, ''Ceratiola ericoides'', the sand heath, sandhill-rosemary or Florida-rosemary, is a species of shrub usually included in the plant family Ericaceae, though treated by some botanists in the Empetraceae. It is the sole species in the genus ''Ceratiola''. It is native to subtropical scrub and dry sandy habitats in the coastal southeastern United States, in Alabama, Florida, Georgia, Mississippi and South Carolina. It commonly occurs together with sand pine and species of oak. Like sand pine, it is adapted to the harsh coastal environment where hot sun and fast draining white sandy soils are common. Cetatiola regenerate by seed after periodic forest fires. Its habitat is important for the endangered Florida sand skink (''Neoseps reynoldsi'') in central Florida. The name derives from the species' superficial similarity to the unrelated European shrub rosemary, familiar for its leaves used as a herb. Florida-rosem ...

Erica (plant)
''Erica'' is a genus of roughly 857 species of flowering plants in the family Ericaceae. The English common names heath and heather are shared by some closely related genera of similar appearance. The genus ''Calluna'' was formerly included in ''Erica'' – it differs in having even smaller scale-leaves (less than 2–3 mm long), and the flower corolla consisting of separate petals. ''Erica'' is sometimes referred to as "winter (or spring) heather" to distinguish it from ''Calluna'' "summer (or autumn) heather". Etymology The Latin word ''erica'' means "heath" or "broom". It is believed that Pliny adapted ''erica'' from Ancient Greek ἐρείκη. The expected Anglo-Latin pronunciation, , may be given in dictionaries (''OED'': "Erica"), but is more commonly heard. Description Most of the species of ''Erica'' are small shrubs from high, though some are taller; the tallest are '' E. arborea'' (tree heath) and '' E. scoparia'' (besom heath), both of which can reach up ...

Daboecia
''Daboecia'' , or St. Dabeoc's heath, is a small genus of flowering plants in the family Ericaceae, containing two evergreen shrubs, closely related to the genus ''Erica''. They are native to cliffs and heathland in southern Atlantic Europe and the Azores. Description They produce urn-shaped flowers in shades of white, pink and red. ''Daboecia'' differ from European ''Erica'' species in having a substantially larger corolla. The leaves are always alternate in ''Daboecia'', never whorled. The generic name comes from the Irish Saint Dabheog. Distribution ''Daboecia'' has an oceanic distribution in western Europe, including western Ireland, western France, northwestern Spain, northwestern mainland Portugal and the Central Group of the Azores. Like ''Erica'' and ''Calluna'' species, ''Daboecia'' are calcifuges, but will tolerate neutral soils and avoid peat. Species * ''Daboecia azorica'' Tutin & E. F.

Calluna
''Calluna vulgaris'', common heather, ling, or simply heather, is the sole species in the genus ''Calluna'' in the flowering plant family Ericaceae. It is a low-growing evergreen shrub growing to tall, or rarely to and taller, and is found widely in Europe and Asia Minor on acidic soils in open sunny situations and in moderate shade. It is the dominant plant in most heathland and moorland in Europe, and in some bog vegetation and acidic pine and oak woodland. It is tolerant of grazing and regenerates following occasional burning, and is often managed in nature reserves and grouse moors by sheep or cattle grazing, and also by light burning. ''Calluna'' was separated from the closely related genus ''Erica'' by Richard Anthony Salisbury, who devised the generic name ''Calluna'' probably from the Ancient Greek (), "beautify, sweep clean", in reference to its traditional use in besoms. The specific epithet ''vulgaris'' is Latin for 'common'. ''Calluna'' is differentiated from ''Er ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Empetrum
''Empetrum'' is a genus of three species of dwarf evergreen shrubs in the heath family Ericaceae. They are commonly known as crowberries and bear edible fruit. They are commonly found in the northern hemisphere, from temperate to subarctic climates, and also in the Southern Andes of South America and on the South Atlantic islands of South Georgia, the Falklands and Tristan da Cunha. The typical habitat is on moorlands, tundra, muskeg and spruce forests. They are also often found in areas of coastal exposure on the sand dunes and dune slacks. Species of ''Empetrum'' include: '' E. nigrum'' (crowberry or black crowberry) and its tetraploid subspecies ''E. nigrum'' ssp. ''hermaphroditum'', '' E. eamesii'' (rockberry or purple crowberry) and '' E. rubrum'' (red crowberry). All are evergreen mat forming shrubs, with small, light green needle-like leaves 3–10 mm long. The flowers are small and either bisexual or dioecious. The fruit is a fairly dry berry. The plant has slender, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Septicidal
Dehiscence is the splitting of a mature plant structure along a built-in line of weakness to release its contents. This is common among fruits, anthers and sporangia. Sometimes this involves the complete detachment of a part; structures that open in this way are said to be dehiscent. Structures that do not open in this way are called indehiscent, and rely on other mechanisms such as decay or predation to release the contents. A similar process to dehiscence occurs in some flower buds (e.g., ''Platycodon'', ''Fuchsia''), but this is rarely referred to as dehiscence unless circumscissile dehiscence is involved; anthesis is the usual term for the opening of flowers. Dehiscence may or may not involve the loss of a structure through the process of abscission. The lost structures are said to be caducous. Association with crop breeding Manipulation of dehiscence can improve crop yield since a trait that causes seed dispersal is a disadvantage for farmers whose goal is to collect ...

Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxonomic ranks from genus upwards are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form of tribe names is as in botany, e.g., Pseudomonadeae, based on the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
