34-654: Centroplacaceae is a family of flowering plants in the order Malpighiales and is recognized by the APG III system of classification. The family comprises two genera: Bhesa , which was formerly recognized in the Celastraceae , and Centroplacus , which was formerly recognized in the Euphorbiaceae , together comprising six species. The Angiosperm Phylogeny Group determined that based on previous phylogenetic analysis, these two genera formed an isolated clade and recognition of

Bhesa is now in the Centroplacaceae , a family in the Malpighiales. and Perrottetia is in the Huerteales . Zhang and Simmons found Pottingeria and Mortonia to be closely related to the families Parnassiaceae and Celastraceae, as they were then defined, but not in either of them. These two genera are therefore in
102-526: A clear break with classification systems being used at that time, the Angiosperm Phylogeny Group resurrected Hutchinson's name, though his concept of Malpighiales included much of what is now in Celastrales and Oxalidales. Malpighiales is monophyletic and in molecular phylogenetic studies, it receives strong statistical support. Since the APG II system was published in 2003, minor changes to
136-530: A fourth order, Huales , separating the family Huaceae into its own order, separate from Oxalidales. Some recent studies have placed Malpighiales as sister to Oxalidales sensu lato (including Huaceae), while others have found a different topology for the COM clade. The COM clade is part of an unranked group known as malvids (rosid II), though formally placed in Fabidae (rosid I). These in turn are part of
170-609: A group that has long been recognized, namely, the rosids . The French botanist Charles Plumier named the genus Malpighia in honor of Marcello Malpighi 's work on plants; Malpighia is the type genus for the Malpighiaceae , a family of tropical and subtropical flowering plants. The family Malpighiaceae was the type family for one of the orders created by Jussieu in his 1789 work Genera Plantarum . Friedrich von Berchtold and Jan Presl described such an order in 1820. Unlike modern taxonomists , these authors did not use
204-431: A history of traditional medicinal uses; poinsettia , a common ornamental plant; the mangosteen ; manchineel tree , one of the most toxic trees in the world; poplars , aspens and cottonwoods which are commonly used for timber – and many more. Malpighiales is a member of a supraordinal group called the COM clade, which consists of the orders Celastrales , Oxalidales , and Malpighiales. Some describe it as containing
238-623: A related order or suborder, are in this most derived malpighian suborder, so that eight of the 10 families of this suborder are Violales. The family Flacourtiaceae has proven to be polyphyletic as the cyanogenic members have been placed in Achariaceae and the ones with salicoid teeth were transferred to Salicaceae. Scyphostegiaceae, consisting of the single genus Scyphostegia has been merged into Salicaceae. The phylogeny of Malpighiales is, at its deepest level, an unresolved polytomy of 16 clades. It has been estimated that complete resolution of

The micropyle has two openings and is therefore called a bistomal micropyle. Flowers with well-developed male and female parts are often functionally unisexual . The seed often has an aril . In bud , the sepals have a quincuncial arrangement. This means that two sepals are inside, two are outside, and

Members often have dentate leaves, with the teeth having a single vein running into a congested and often deciduous apex (i.e., violoid, salicoid, or theoid). Also, zeylanol has recently been discovered in Balanops and Dichapetalum which are in
374-426: Is the Euphorbiaceae , with about 6300 species in about 245 genera . In a 2009 study of DNA sequences of 13 genes , 42 families were placed into 16 groups , ranging in size from one to 10 families. The relationships among these 16 groups remain poorly resolved. Malpighiales and Lamiales are the two large orders whose phylogeny remains mostly unresolved. Some examples of notable species include cassava ,

510-444: The tropics and subtropics , with only a few species extending far into the temperate regions. The 1200 to 1350 species are in about 100 genera . All but seven of these genera are in the large family Celastraceae . Until recently, the composition of the order and its division into families varied greatly from one author to another. The Celastrales are a diverse order that has no conspicuous distinguishing characteristic , so

It continues to be the subject of a dispute about whether its proper name is Forsellesia or Glossopetalon . After being placed elsewhere, Canotia , Brexia , and Plagiopteron were found to belong in the Celastraceae. The family Hippocrateaceae was found to be deeply nested within
578-462: The Celastraceae and is no longer recognized as a separate family. In 2000, Vincent Savolainen et alii found that three families - Lepidobotryaceae , Parnassiaceae , and Celastraceae - were closely related. They stated that these three families should constitute the order Celastrales, and this idea was accepted by the Angiosperm Phylogeny Group , which later subsumed the Parnassiaceae into
612-495: The Celastraceae. Savolainen and co-authors also excluded Lophopyxis from the Celastrales. Lophopyxis now constitutes a monogeneric family in the Malpighiales. In 2001, in a molecular phylogenetic study of DNA sequences , Mark Simmons and others confirmed all of these results except for the placement of Lophopyxis and the Lepidobotryaceae, which they did not sample. In 2006, Li-Bing Zhang and Mark Simmons produced
646-493: The Celastrales that achieved better resolution than the 2006 study by sampling more species and more DNA. They found the same pentatomy of five strongly supported groups that the previous study had found, but only weak to moderate support for any relationships between the five groups. In the APG III system, the family Celastraceae was expanded to consist of these five groups. No one has yet published an intrafamilial classification for
680-404: The Celastrales. They found that Siphonodon and Empleuridium are proper members of the Celastraceae, removing considerable doubt about their placement there. They also showed that the small family Stackhousiaceae, consisting of three genera, is embedded in the Celastraceae. Except for taxa that were not sampled, these results were confirmed by the second phylogeny of the Celastrales, which
714-406: The ambiguity and complexity of its definition , the Celastraceae became a dumping ground for genera of dubious affinity . Several genera were assigned to this family with considerable doubt about whether they really belonged there. Also, some genera that properly belong in the Celastraceae were placed elsewhere. By the end of the 20th century, Goupia and Forsellesia had been excluded from

In their APG II classification in 2003, the Angiosperm Phylogeny Group recognized three families in the Celastrales – Lepidobotryaceae , Parnassiaceae , and Celastraceae . When they revised their classification in 2009, they recognized only two families because Pottingeria and

This study recovered a group of rosids unlike any group found in any previous system of plant classification . To make

Some family delimitations within the order have changed, as well, most notably, the segregation of Calophyllaceae from Clusiaceae sensu lato when it was shown that the latter is paraphyletic . Some differences of opinion on family delimitation exist, as well. For example, Samydaceae and Scyphostegiaceae may be recognized as families or included in a large version of Salicaceae . The group

Perhaps the most conspicuous and unusual trait of the Celastrales is the nectary disk, a feature that it shares with another rosid order, Sapindales . Since the orders are not closely related , the disk must have been an independent development in each of these lines .

No relationships were resolved among these groups. In 2008, Simmons and others produced a phylogeny of
