Ericaceae
The Ericaceae () are a Family (biology), 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 about 4,250 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 (plant), Erica'', ''Cassiope'', ''Daboecia'', and ''Calluna'' for example). Description The Ericaceae contain a morphologically diverse range of taxa, including Herbaceous plant, herbs, chamaephyte, dwarf shrubs, shrubs, and trees. Their leaves are usually evergreen, alternate or whorled, simple and without stipules. Their flowers are Plant sexuality#Individual plant sexuality, hermaphrodite and show considerable variability.

Ceratiola
''Ceratiola'' is a genus of flowering plants with a single species, ''Ceratiola ericoides'', a shrub endemic to the Southeastern United States. Names ''C. ericoides'' is commonly known as Florida rosemary, sand heath, scrub rosemary, or sandhill rosemary. Description Florida rosemary can grow to tall. The growth form is a rounded shrub with dense branching. Dark green leaves are needle-like, eight to twelve mm long and one mm wide, and smell like the herb rosemary. The yellow to brown flowers are small. The green or yellow fruit is in diameter, and is a juicy drupe containing two seeds. Reproduction The Florida rosemary is dioecious and wind pollinated. Flowers are in the leaf axils on the previous years growth. Flowers bloom on leaf axils of the previous year's growth from September through October. Fruits ripen in January through April. Flowers and fruit may remain on the plant year-round. Plants do not produce seed until they are 10 to 15 years old. Seed production p ...

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 millimetres 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". 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 to tall. All are evergreen, with minute, needle-like leaves long. Flowers are sometimes axillary, and sometimes borne in terminal umbels or spikes, and are usually outward or downward facing. The seeds are very small, and in some species may survi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daboecia
''Daboecia'' , or St. Dabeoc's heath, is a small genus of flowering plants in the family (biology), family Ericaceae, containing two evergreen shrubs, closely related to the genus ''Erica (plant), Erica''. They are native plant, 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 (flower), 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, Azores, Central Group of the Azores. Like ''Erica'' and ''Calluna'' species, ''Daboecia'' are calcifuges, but will tolerate neutral soils and avoid peat. Species * ''Daboecia azorica'' Tom Tut ...

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. Description ''Calluna'' can reach in height. It has small-scale leaves (less than 2–3 mm long) borne in opposite and decussate pairs, whereas those of '' Erica'' are generally larger and in whorls of 3–4, sometimes 5.

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. Species of ''Empetrum'' include: '' E. nigrum'' (crowberry) and its tetraploid subspecies ''E. nigrum'' ssp. ''hermaphroditum'', '' E. eamesii'' and '' E. rubrum''. Description All three species are evergreen mat forming shrubs, with small, light green needle-like leaves long. The flowers are small and either bisexual or dioecious. The fruit is a fairly dry berry. The plant has slender, wiry, spreading branches covered with short, narrow, stiff leaves, the margins of which are recurved so as to form a hollow cylinder concealing the hairy under face of the leaf, which protects against excessive loss of water from the leaf. Taxonomy The genus and related ones such as ''Ceratiola'' and '' Corema'' were for most of the 20th century classified in their own family Empetraceae, but molecular data, leaf ...

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, digestion by herbivores, 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 farmer ...

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 taxa ranked above species 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] |
