Sabiaceae is a family of flowering plants that were placed in the order Proteales according to the APG IV system. It comprises three genera, Meliosma , Ophiocaryon and Sabia , with 66 known species, [2] native to tropical to warm temperate regions of southern Asia and the Americas. The family has also been called Meliosmaceae Endl., 1841, nom. rej.
The anthesis is extremely short. The anthers open within the bud, but enclosed in the staminodes. On maturing the bud opens explosively at the smallest touch releasing the pollen into the air.
Plants from this genus live in humid areas along rivers, in tropical forests or in warm temperatures.
Cyanolipids absent. Pentacyclic triterpenoids, flavonols, proanthocyanidins and tannins present. The plants are not cyanogenetic.
Some species of Meliosma have a limited use in gardening and horticulture.
The fossil genus Insitiocarpus has been found in deposits from the Cenomanian period, while the other extant genera Sabia and Meliosma have been found in European deposits from the Turonian and the Maastrichtian, respectively. [1] The appearance of the first Sabiaceae has been dated to 122–118 million years ago.
Sabia macrofossils have been recovered from the late Zanclean stage of Pliocene sites in Pocapaglia, Italy. [3]
The Sabiaceae are a group of flowering plants that are included in the eudicots clade, where they form part of the basal level. In this regard they are similar to the Proteaceae, with which they share, for example, a nectariferous hypogynous disc, although they differ in the number of floral parts and the radial pentameric symmetry is completely original. Based on molecular and morphological data, the APW (Angiosperm Phylogeny Website) considers that they form part of the order Proteales, one of four families that includes the Proteaceae, the Nelumbonaceae, and the Platanaceae (cf. AP-website).
In the Cronquist system the family was placed in the order Ranunculales, but more recent classifications place it as the sole family in the order Sabiales, or (as in the APG II system and APG III system), as unplaced to order and left among the basal lineages of the eudicots. [4] The Angiosperm Phylogeny Website, however, suggests the addition of Sabiaceae to the eudicot order Proteales would be sensible. [5] This was done in the APG IV system. [6]
The family consists of three genera, together about 160 species of woody plants. The genus Sabia often are lianas, while those in the genera Meliosma and Ophiocaryon are trees and shrubs; the latter two are sometimes treated in a separate family Meliosmaceae.
The family includes three genera that can be distinguished as follows:
Platanaceae, the plane family, is a family of flowering plants in the order Proteales. The family consists of only a single extant genus Platanus, with twelve known species. The plants are tall trees, native to temperate and subtropical regions of the Northern Hemisphere. The hybrid London plane is widely planted in cities worldwide.
Geraniaceae is a family of flowering plants placed in the order Geraniales. The family name is derived from the genus Geranium. The family includes both the genus Geranium and the garden plants called geraniums, which modern botany classifies as genus Pelargonium, along with other related genera.
The Canellaceae are a family of flowering plants in the order Canellales. The order includes only one other family, the Winteraceae. Canellaceae is native to the Afrotropical and Neotropical realms. They are small to medium trees, rarely shrubs, evergreen and aromatic. The flowers and fruit are often red.
Saxifragaceae is a family of herbaceous perennial flowering plants, within the core eudicot order Saxifragales. The taxonomy of the family has been greatly revised and the scope much reduced in the era of molecular phylogenetic analysis. The family is divided into ten clades, with about 640 known species in about 35 accepted genera. About half of these consist of a single species, but about 400 of the species are in the type genus Saxifraga. The family is predominantly distributed in the northern hemisphere, but also in the Andes in South America.
Drosophyllum is a genus of carnivorous plants containing the single species Drosophyllum lusitanicum, commonly known as Portuguese sundew or dewy pine. In appearance, it is similar to the related genus Drosera, and to the much more distantly related Byblis.
Commelinaceae is a family of flowering plants. In less formal contexts, the group is referred to as the dayflower family or spiderwort family. It is one of five families in the order Commelinales and by far the largest of these with about 731 known species in 41 genera. Well known genera include Commelina (dayflowers) and Tradescantia (spiderworts). The family is diverse in both the Old World tropics and the New World tropics, with some genera present in both. The variation in morphology, especially that of the flower and inflorescence, is considered to be exceptionally high amongst the angiosperms.
Parnassiaceae Gray were a family of flowering plants in the eudicot order Celastrales. The family is not recognized in the APG III system of plant classification. When that system was published in 2009, Parnassiaceae were treated as subfamily Parnassioideae of an expanded family Celastraceae.
The Hernandiaceae are a family of flowering plants (angiosperms) in the order Laurales. Consisting of five genera with about 58 known species, they are distributed over the world's tropical areas, some of them widely distributed in coastal areas, but they occur from sea level to over 2000 m.
Trochodendraceae is the only family of flowering plants in the order Trochodendrales. It comprises two extant genera, each with a single species along with up to five additional extinct genera and a number of extinct species. The living species are native to south east Asia. The two living species both have secondary xylem without vessel elements, which is quite rare in angiosperms. As the vessel-free wood suggests primitiveness, these two species have attracted much taxonomic attention.
Chloranthaceae is a family of flowering plants (angiosperms), the only family in the order Chloranthales. It is not closely related to any other family of flowering plants, and is among the early-diverging lineages in the angiosperms. They are woody or weakly woody plants occurring in Southeast Asia, the Pacific, Madagascar, Central and South America, and the West Indies. The family consists of four extant genera, totalling about 77 known species according to Christenhusz and Byng in 2016. Some species are used in traditional medicine. The type genus is Chloranthus. The fossil record of the family, mostly represented by pollen such as Clavatipollenites, extends back to the dawn of the history of flowering plants in the Early Cretaceous, and has been found on all continents.
Peridiscaceae is a family of flowering plants in the order Saxifragales. Four genera comprise this family: Medusandra, Soyauxia, Peridiscus, and Whittonia., with a total of 12 known species. It has a disjunct distribution, with Peridiscus occurring in Venezuela and northern Brazil, Whittonia in Guyana, Medusandra in Cameroon, and Soyauxia in tropical West Africa. Whittonia is possibly extinct, being known from only one specimen collected below Kaieteur Falls in Guyana. In 2006, archeologists attempted to rediscover it, however, it proved unsuccessful.
Eupomatia is a genus of three species of plants in the ancient family Eupomatiaceae, and is the sole genus in the family. Eupomatiaceae is recognised by most taxonomists and classified in the plant order Magnoliales. The three described species are shrubs or small trees, native to the rainforests and humid eucalypt forests of eastern Australia and New Guinea. The type species Eupomatia laurina was described in 1814 by Robert Brown.
Didymeles is a genus of flowering plants. It is variously treated as the only genus of the family Didymelaceae — or in the family Buxaceae, as in the APG IV system.
Haloragaceae is a eudicot flowering plant family in the order Saxifragales, based on the phylogenetic APG system. In the Cronquist system, it was included in the order Haloragales.
Aphloia is a genus of flowering plants that contains a single species, Aphloia theiformis, the sole species of the monogeneric family Aphloiaceae. It is a species of evergreen shrubs or small trees occurring in East Africa, Madagascar, the Mascarene Islands and the Seychelles.
Geissoloma is a genus of flowering plants in the monotypic family Geissolomataceae, native to the Cape Province of South Africa. Geissoloma marginatum is the only species in the family. It is sometimes called guyalone in English. The plants are xerophytic evergreen shrubs and are known to accumulate aluminum.
The Cleomaceae are a small family of flowering plants in the order Brassicales, comprising about 220 species in two genera, Cleome and Cleomella. These genera were previously included in the family Capparaceae, but were raised to a distinct family when DNA evidence suggested the genera included in it are more closely related to the Brassicaceae than they are to the Capparaceae. The APG II system allows for Cleomaceae to be included in Brassicaceae. Cleomaceae includes C3, C3–C4, and C4 photosynthesis species.
Meliosma oldhamii is a species of deciduous tree in the family Sabiaceae, which grows up to 20 meters in height. It has a narrow crown when young, and it becomes more wide-spreading with age. It is endemic to China, Japan, and Korea.
In phylogenetic nomenclature, the Pentapetalae are a large group of eudicots that were informally referred to as the "core eudicots" in some papers on angiosperm phylogenetics. They comprise an extremely large and diverse group accounting for about 65% of the species richness of the angiosperms, with wide variability in habit, morphology, chemistry, geographic distribution, and other attributes. Classical systematics, based solely on morphological information, was not able to recognize this group. In fact, the circumscription of the Pentapetalae as a clade is based on strong evidence obtained from DNA molecular analysis data.
Berberidopsis beckleri is a species of climbing plant found in cool rainforests in eastern Australia. Its common name is the montane tape vine. Ferdinand von Mueller described the plant as Streptothamnus beckleri from collections at the Clarence River.
