Rosids

Template:Short description Script error: No such module "Automated taxobox". The rosids are members of a large clade (monophyletic group) of flowering plants, containing about 70,000 species,[2]Template:R/superscript more than a quarter of all angiosperms.[3]Template:R/superscript

The clade is divided into 16 to 20 orders, depending upon circumscription and classification. These orders, in turn, together comprise about 140 families.[4]Template:R/superscript

Fossil rosids are known from the Cretaceous period. Molecular clock estimates indicate that the rosids may have originated in the Aptian or Albian stages of the Cretaceous, between 125 and 99.6 million years ago.[5]Template:R/superscript[6]Template:R/superscript

Today's broadleaved forests are dominated by rosid species, which in turn help with diversification in many other living lineages. Additionally, rosid herbs and shrubs are a significant part of arctic/alpine and temperate floras. The clade also includes some aquatic, desert and parasitic plants.[7]

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 plants published in 1830 by Friedrich Gottlieb Bartling.[8]Template:R/superscript The clade was later renamed "Rosidae" and has been variously delimited by different authors. The name "rosids" is informal and not assumed to have any particular taxonomic rank like the names authorized by the ICBN. The rosids are monophyletic based upon evidence found by molecular phylogenetic analysis.[citation needed]

Relationships

The rosids and Saxifragales form the superrosids clade.[2]Template:R/superscript[9]Template:R/superscript This is one of three groups that comprise the Pentapetalae (core eudicots minus Gunnerales),[10]Template:R/superscript the others being Dilleniales and the superasterids (Berberidopsidales, Caryophyllales, Santalales, and asterids).[9]Template:R/superscript

Classification

Three different definitions of the rosids were used. Some authors included the orders Saxifragales and Vitales in the rosids.[11]Template:R/superscript Others excluded both of these orders.[9]Template:R/superscript The circumscription used in this article is that of the APG IV classification, which includes Vitales, but excludes Saxifragales.[1]Template:R/superscript

Thus, the rosids consist of two groups: the order Vitales and the eurosids. The eurosids, in turn, are divided into two groups: fabids (Fabidae, eurosids I) and malvids (Malvidae, eurosids II).[1]Template:R/superscript

Orders

The rosids consist of 17 orders. In addition to Vitales, there are eight orders in fabids and eight orders in malvids. Some of the orders have only recently been recognized.[9]Template:R/superscript These are Vitales,[12]Template:R/superscript Zygophyllales,[13]Template:R/superscript Crossosomatales,[14]Template:R/superscript Picramniales,[15]Template:R/superscript and Huerteales.[16]Template:R/superscript

Phylogeny

The phylogeny of rosids shown below is adapted from the Angiosperm Phylogeny Website.[9]Template:R/superscript

Script error: No such module "Clade".

The nitrogen-fixing clade contains a high number of actinorhizal plants (which have root nodules containing nitrogen fixing bacteria, helping the plant grow in poor soils). Not all plants in this clade are actinorhizal, however.[17]Template:R/superscript
