14-443: Wellingtonia can mean: A genus of plants in the family Sabiaceae , usually treated as a synonym of the genus Meliosma . A vernacular name for the coniferous tree Sequoiadendron giganteum . Wellingtonia (horse) was a thoroughbred racehorse in the late 19th century. Topics referred to by the same term [REDACTED] This disambiguation page lists articles associated with
28-629: 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. The appearance of the first Sabiaceae has been dated to 122–118 million years ago. Sabia macrofossils have been recovered from
42-522: 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 , 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
56-658: 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
70-961: The Platanaceae and Nelumbonaceae are Northern Hemisphere plants. The current APG IV classification represents a slight change from the APG I system of 1998, which firmly did accept family Platanaceae as being separate from the order. Under APG IV, this is the current circumscription of the order: The Cronquist system of 1981 recognized such an order and placed it in subclass Rosidae in class Magnoliopsida [= dicotyledons ]. It used this circumscription: The Dahlgren system and Thorne system (1992) recognized such an order and placed it in superorder Proteanae in subclass Magnoliidae [=dicotyledons]. The Engler system , in its update of 1964 , also recognized this order and placed it in subclass Archichlamydeae of class Dicotyledoneae . The Wettstein system , last revised in 1935, recognized this order and placed it in
84-647: The Proteales are very different from each other due to their very early divergence. They possess seeds with little or no endosperm. The ovules are often atropic . The oldest fossils of Proteales are of the nelumbonaceous genus Notocyamus from the Barremian stage of the Early Cretaceous of Brazil , 126-121 Ma ( million years ago ). According to molecular clock calculations, the lineage that led to Proteales split from other plants about 128 Ma or 125 Ma. Within
98-455: The Proteales include the proteas of South Africa, the banksia and macadamia of Australia, the planetree , and the sacred lotus . The origins of the order are clearly ancient, with evidence of diversification in the mid- Cretaceous , roughly over 100 million years ago. Of notable interest is the family's modern distribution; the Proteaceae is predominantly a Southern Hemisphere family, while
112-414: 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
126-418: The classification system of Rolf Dahlgren , the Proteales were in the superorder Proteiflorae, also called Proteanae; The APG II system (of 2003) also recognizes this order, placing it in the clade Eudicots , with the following circumscription: with "+ ..." = optionally separate family (that may be split off from the preceding family). The APG III system of 2009 followed this same approach, but favored
140-404: 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: Proteales Proteales is an order of flowering plants consisting of three (or four) families. The Proteales have been recognized by almost all taxonomists. The representatives of
154-465: The late Zanclean stage of Pliocene sites in Pocapaglia , Italy . 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

#1732944339533168-527: The narrower circumscription of the three families, firmly recognizing three families in Proteales: Nelumbonaceae, Platanaceae, and Proteaceae. The Angiosperm Phylogeny Website , however, suggests the addition of Sabiaceae , which the APG III system did not place in any order in the eudicots, would be sensible. The APG IV system of 2016 added family Sabiaceae to the order. Well-known members of
182-528: 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 . The Angiosperm Phylogeny Website , however, suggests the addition of Sabiaceae to the eudicot order Proteales would be sensible. This was done in the APG IV system . The family consists of three genera , together about 160 species of woody plants. The genus Sabia often are lianas, while those in
