Ericales
The Ericales are a large and diverse order of dicotyledons. Species in this order have considerable commercial importance including for Camellia sinensis, tea, persimmon, blueberry, kiwifruit, Brazil nuts, Argania, argan, and azalea. The order includes trees, shrub, bushes, lianas, and herbaceous plants. Together with ordinary Photosynthesis, autophytic plants, the Ericales include chlorophyll-deficient mycoheterotrophic plants (e.g., ''Sarcodes sanguinea'') and carnivorous plants (e.g., genus ''Sarracenia''). Many species have five petals, often grown together. Fusion of the petals as a trait was traditionally used to place the order in the subclass Sympetalae. Mycorrhiza, Mycorrhizal associations are quite common among the order representatives, and three kinds of mycorrhiza are found exclusively among Ericales (namely, ericoid, arbutoid and monotropoid mycorrhiza). In addition, some families among the order are notable for their exceptional ability to accumulate aluminum. Er ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Primulaceae
The Primulaceae , commonly known as the primrose family (but not related to the Onagraceae, evening primrose family), are a family (biology), family of Herbaceous plant, herbaceous and woody flowering plants including some favourite garden plants and wildflowers. Most are Perennial plant, perennial though some species, such as Anagallis arvensis, scarlet pimpernel, are annual plant, annuals. Previously one of three families in the Order (biology), order Primulales, it underwent considerable genus, generic re-alignment once molecular phylogenetic methods were used for taxonomic classification. The order was then submerged in a much enlarged order Ericales and became a greatly enlarged Primulaceae ''sensu lato'' (''s.l''). In this new classification of the Angiosperm Phylogeny Group, each of the Prumulales families was reduced to the rank of subfamily of Primulaceae ''s.l.'' The original Primulaceae (Primulaceae ''sensu stricto'' or ''s.s.'') then became subfamily Primuloideae, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theophrastaceae
Theophrastoideae is a small subfamily of flowering plants in the family Primulaceae. It was formerly recognized as a separate family Theophrastaceae. As previously circumscribed, the family consisted of eight genera and 95 species of trees or shrubs, native to tropical regions of the Americas. Description The two subclades or tribes of Theophrastoideae, Theophrasteae (Theophrastaceae ''s.s.'') and Samoleae, share only the presence of staminodes. The species of ''Samolus'' are perennial, herbaceous or suffrutescent (shrubby) and characterised by perigynous flowers. The remaining genera (Theophrastaceae ''s.s.'') are generally evergreen shrubs or small trees, with hypogynous flowers. Taxonomy History Linnaeus, in formally describing the genera, placed ''Theophrasta'' and related genera in a group he named ''Pentandria Monogynia'' (i.e 5 stamens, one pistil), his system being based on sexual characteristics. Jussieu arranged Linnaeus' genera in a hierarchical system of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Actinidiaceae
The Actinidiaceae are a small family of flowering plants. The family has three genera and about 360 species and is a member of the order Ericales. Distribution They are temperate and subtropical woody vines, shrubs, and trees, native to Asia ('' Actinidia'' or kiwifruit, '' Clematoclethra'', and ''Saurauia'') and Central America and South America (''Saurauia'' only). ''Saurauia'', with its 300 species, is the largest genus in this family. Although now confined to Asia and tropical Central and South America, evidence indicates in the past the family had a wider distribution. The now extinct genus ''Parasaurauia'' is thought to have belonged to the Actinidiaceae and lived in North America during the early Campanian. Characteristics The plants are usually small trees or shrubs, or sometimes vines (''Actinidia''). The alternate, simple, spiral leaves have serrated or entire margins. They lack stipules or are minutely stipulated. They are often beset with rather flattened brist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diapensiaceae
Diapensiaceae is a small family of flowering plants, which includes 15 species in 6 genera. The genera include '' Berneuxia'' Decne. (1 species), '' Diapensia'' L. (5 species), ''Galax'' Sims (1 species), '' Pyxidanthera'' Michx. (2 species), '' Shortia'' Torr. & A.Gray (4 species), and '' Schizocodon'' Siebold & Zucc. (2 species). Members of this family have little economic importance; however, some members are cultivated by florists. Taxonomy Past literature classified Diapensiaceae as an old family, without defining the meaning of old. The name '' Diapensia'' was given to ''Diapensia lapponica'' by Linnaeus. Previously, it was the Greek name of sanicle. The family, originally including only ''Diapensia lapponica'', was named by Heinrich Friedrich Link in 1829. Concerning the interrelationships in Diapensiaceae, debate still remains regarding the recognition of ''Schizocodon'' and whether it should be separate from ''Shortia''. However, recent molecular studies support the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roridula
''Roridula'' (; from Latin ''roridus'' "dewy") is a genus of evergreen, insect-trapping shrubs, with two species, of about 1⅓–2 m (4–6⅔ ft). It is the only genus in the family Roridulaceae. It has thin, woody, shyly branching, upright, initially brown, later grey stems, with lance- to awl-shaped leaves crowded at their tips. The star-symmetrical flowers consist from the outside in of five, green or reddish, free sepals, alternating with five white, pink or purple, free petals. Further to the middle and opposite the sepals are five stamens with the anthers initially kinked down. These suddenly flip up if the nectar-containing swelling at its base is being touched. The center of the flower is occupied by a superior ovary. The leaves and sepals carry many sticky tentacles of different sizes, that trap insects. ''Roridula'' does not break down the insect proteins, but bugs of the genus '' Pameridea'' prey on the trapped insects. These later deposit their feces on the leaves ...

Tetrameristaceae
Tetrameristaceae is a family of flowering plants. The family consists of five species, of trees or shrubs, in three genera: * '' Pelliciera'' in Central and South America * '' Pentamerista'' in the Guyanas * '' Tetramerista'' in Southeast Asia The APG II system places this family in the order Ericales, of the asterids. In the APG III system The APG III system of flowering plant classification is the third version of a modern, mostly molecular-based, system of plant taxonomy being developed by the Angiosperm Phylogeny Group (APG). Published in 2009, it was superseded in 2016 by a fur ..., the genus '' Pelliciera'', previously treated as its own family, Pellicieraceae, is included in Tetrameristaceae.

Clethraceae
The Clethraceae are a small family of flowering plants in the order Ericales, composed of two genera, ''Clethra'' and ''Purdiaea'', with approximately 75 species. They are native to warm temperate to tropical regions of Asia and the Americas, with one species also on Madeira. In the past, most botanists included only ''Clethra'' in the family, but recent research has shown ''Purdiaea'', previously placed in the closely related family Cyrillaceae The Cyrillaceae are a small family (biology), family of flowering plants in the order Ericales, native to warm temperate to tropical regions of the Americas.

Cyrillaceae
The Cyrillaceae are a small family of flowering plants in the order Ericales, native to warm temperate to tropical regions of the Americas. The family comprises two genera, '' Cliftonia'' and ''Cyrilla'', each containing a single species, '' Cliftonia monophylla'' and ''Cyrilla racemiflora''. However, additional species of ''Cyrilla'' are now often recognized and the genus is in need of taxonomic revision. In the past, many botanists included a third genus, ''Purdiaea'', in the family, though recent research has shown this genus is better placed in the closely related family Clethraceae. Fossil record Fossil ''Cyrilla'' and ''Cliftonia'' leaves, wood and pollen have been reported from the Neogene Lower Rhine region brown coal. Leaf fragments of ''Cyrilla'' have been found frequently in brown coals of central Europe. The Cyrillaceae formed part of the Tertiary bog flora where they constituted an important component of the shrubby vegetation. Among fossil ''Cyrilla'' from the Te ...

Sladeniaceae
Sladeniaceae is a family of flowering plants containing tree species found in subtropical to tropical environments in East Africa ('' Ficalhoa''), Burma, Yunnan, and Thailand ('' Sladenia''). The family consists of trees with alternate, simple leaves without stipules, and flowers arranged in cymose inflorescences. The circumscription of the family is variable, with some systems describing the family as consisting solely of the genus ''Sladenia'', which has been variously considered a member of the Theaceae, the Actinidiaceae, the Dilleniaceae, or the Ternstroemiaceae. Other systems include the genus '' Ficalhoa'' and possibly the genus '' Pentaphylax'' in a family with ''Sladenia''. Morphological studies of the ''Sladenia'' embryo suggest it has unique characteristics that merit placing the genus in its own family. However, the plant family is poorly studied and initial phylogenetic In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", an ...

Mitrastemonaceae
''Mitrastemon'' is a genus of two widely disjunct species of parasitic plants. It is the only genus within the family Mitrastemonaceae. ''Mitrastemon'' species are root endoparasites, which grow on Fagaceae. It is also a non-photosynthetic plant that parasitizes other plants such as ''Castanopsis sieboldii''. The parasitic plant was first discovered by botanist Eizi Matuda during an expedition to Mt. Ovand in the state of Chiapas, Mexico (Matuda, 1947). The different species were originally named by a friend of Matuda, Yamamoto in 1925–1926. ''Mitrastemon yamamotoi'' is a protandrous plant. Its flowers go through a male phase before transforming into their final female form. The flowers of ''M. yamamotoi'' attract a variety of insects ranging from wasps to flies and beetles. Among these, beetles are the best pollinators for this plant since their visit to the flower would pick up a large amount of pollen and they would pollinate from each of the flowers that they had already v ...
