Huerteales
Huerteales is the botanical name for an order of flowering plants.Peter F. Stevens (2001 onwards). "Huerteales". In: Angiosperm Phylogeny Website. In: Missouri Botanical Garden Website. (see ''External links'' below) It is one of the 17 orders that make up the large eudicot group known as the rosids in the APG III system of plant classification. Within the rosids, it is one of the orders in Malvidae, a group formerly known as eurosids II and now known informally as the malvids. This is true whether Malvidae is circumscribed broadly to include eight orders as in APG III, or more narrowly to include only four orders. Huerteales consists of four small families, Petenaeaceae, Gerrardinaceae, Tapisciaceae, and Dipentodontaceae.Andreas Worberg, Mac H. Alford, Dietmar Quandt, and Thomas Borsch. 2009.

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 Published in 2009, it was superseded in 2016 by a further revision, the APG IV system. Along with the publication outlining the new system, there were two accompanying publications in the same issue of the Botanical Journal of the Linnean Society: * The first, by Chase & Reveal, was a formal phylogenetic classification of all land plants (embryophytes), compatible with the APG III classification. As the APG have chosen to eschew ranks above order, this paper was meant to fit the system into the existing Linnaean hierarchy for those that prefer such a classification. The result was that all land plants were placed in the class Equisetopsida, which was then divided into 16 subclasses and a multitude of superorders. * The second, by Haston ''et al.'', was a linear sequence of families followi ...

Dipentodon
Dipentodon is a genus of flowering plants in the Family (biology), family Dipentodontaceae. Its only species, ''Dipentodon sinicus'', is a small, deciduous tree native to southern China, northern Myanmar, and northern India.Jinshuang Ma and Bruce Bartholomew. 2008. "Dipentodontaceae" pages 494-495. In: Zhengyi Wu, Peter H. Raven, and Deyuan Hong (editors). ''Flora of China'' volume 11. Science Press: Beijing, China; Missouri Botanical Garden Press: St. Louis, Missouri, USA. It has been little studied and until recently its affinities remained obscure. Description ''Dipentodon sinicus'' is a small, deciduous tree. The leaves are Stipule, stipulate, Leaf#Arrangement on the stem, alternate, and Leaf#Divisions of the lamina (blade), simple, with Leaf shape, serrate margins. The inflorescence is variable in form, usually an abbreviated, umbelliform Cyme (botany), cyme containing 25 to 30 small flowers. The flowers are Floral symmetry, actinomorphic and yellowish green. The sepals and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gerrardinaceae
''Gerrardina'' is a genus of two species of trees, shrubs, and scrambling shrubs found in southeastern Africa. Until recently, the genus was placed in the polyphyletic family Flacourtiaceae, but it was abnormal there due to its apical placentation, small embryos, and mucilaginous foliar epidermis. Analyses of DNA data indicated that the genus did not fit in any known plant family and not clearly in any then-recognized order, and a new family, Gerrardinaceae, was thus created for it.Alford, M. H. 2006. Gerrardinaceae: a new family of African flowering plants unresolved among Brassicales, Huerteales, Malvales, and Sapindales. ''Taxon'' 55: 959-964.

Petenaeaceae
''Petenaea cordata'' (from northern Central America) was first described in Elaeocarpaceae and later placed in Tiliaceae, but most authors have been uncertain about its familial affinities. It was considered a taxon ''incertae sedis'' in the Angiosperm Phylogeny Group classification (APG III). Molecular analyses based on a recent collection from Guatemala indicate a distant, weakly supported sister-group relationship to the African genus ''Gerrardina'' (Gerrardinaceae; Huerteales). As no obvious synapomorphies exist for ''Gerrardina'' and ''Petenaea'', the new monogeneric family Petenaeaceae was proposed. The polymorphic order Huerteales now comprises four small families: Dipentodontaceae, Gerrardinaceae, Petenaeaceae and Tapisciaceae. ''Petenaea cordata'' is the only species in the genus ''Petenaea''. Description Trees to c. 10 m, or large shrubs. Stems often tinged red, villous-tomentose. Leaves minutely stipulate; petioles 5–11 cm, densely short villous, red; blades 8.5- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Malvids
The rosids are members of a large clade (monophyletic group) of flowering plants, containing about 70,000 species, more than a quarter of all angiosperms. The clade is divided into 16 to 20 orders, depending upon circumscription and classification. These orders, in turn, together comprise about 140 families. Fossil rosids are known from the Cretaceous period. Molecular clock estimates indicate that the rosids originated in the Aptian or Albian stages of the Cretaceous, between 125 and 99.6 million years ago. Today's forests are highly dominated by rosid species, which in turn helped with diversification in many other living lineages. Additionally, rosid herbs and shrubs are also a significant part of arctic/alpine, temperate floras, aquatics, desert plants, and parasites. Name The name is based upon the name "Rosidae", which had usually been understood to be a subclass. In 1967, Armen Takhtajan showed that the correct basis for the name "Rosidae" is a description of a group of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Perrottetia Sandwicensis
''Perrottetia'' is a genus of flowering plants in the family Dipentodontaceae described as a family in 1824. Species occur in China, Southeast Asia, Papuasia, Hawaii, Australia, and Latin America. It is the largest genus of the recently described order Huerteales. Taxonomy This genus was previously placed in the staff vine family, Celastraceae., but molecular evidence has shown that it not related and better placed with ''Dipentodon'' in a separate family Dipentodontaceae.

Eudicot
The eudicots, Eudicotidae, or eudicotyledons are a clade of flowering plants mainly characterized by having two seed leaves upon germination. The term derives from Dicotyledons. Traditionally they were called tricolpates or non-magnoliid dicots by previous authors. The botanical terms were introduced in 1991 by evolutionary botanist James A. Doyle and paleobotanist Carol L. Hotton to emphasize the later evolutionary divergence of tricolpate dicots from earlier, less specialized, dicots. Numerous familiar plants are eudicots, including many common food plants, trees, and ornamentals. Some common and familiar eudicots include sunflower, dandelion, forget-me-not, cabbage, apple, buttercup, maple, and macadamia. Most leafy trees of midlatitudes also belong to eudicots, with notable exceptions being magnolias and tulip trees which belong to magnoliids, and ''Ginkgo biloba'', which is not an angiosperm.
