The basal eudicots are a group of 13 related families of flowering plants in four orders: Buxales, Proteales, Ranunculales and Trochodendrales. [1] [a] Like the core eudicots (the rest of the eudicots), they have pollen grains with three colpi (grooves) or other derived structures, [4] and usually have flowers with four or five petals (sometimes multiples of four or five, sometimes reduced or ...
Basal eudicot is an informal name for a paraphyletic group. The core eudicots are a monophyletic group. [11] A 2010 study suggested the core eudicots can be divided into two clades, Gunnerales and a clade called Pentapetalae, comprising all the remaining core eudicots. [12] The Pentapetalae can be then divided into three clades: [citation needed]
The leaves form a basal rosette about the caudex. They are oval-shaped, green in color and sparsely covered in coarse white hairs, up to 4 centimeters long, and with smooth or wavy edges. Leaves located higher up the stem are smaller.
Though traditionally recognized as a large genus with many Old World and New World members, more recent evaluations of the relationships among these species using genetic data suggest there are two major groups within the old genus Arabis. These two groups are not each other's closest relatives, so have been split into two separate genera.

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. [2] 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 ...
Arabis allionii is a species of flowering plant in the family Brassicaceae, native to the mountains of central and southern Europe and southern Turkey. [1] The Royal Horticultural Society lists it as a garden plant for attracting pollinators, but gives its common name as "Siberian wallflower", suggesting that they have it confused with Erysimum × marshallii.
Arabis ferdinandi-coburgii is a species of flowering plant of the genus Arabis belonging to the family Brassicaceae. [1] It was described in 1903 by Johann Kellerer and Franz Sündermann and was named after Tsar Ferdinand I of Bulgaria. The stem of the plant is 6–12 cm high. The inflorescence is apical and racemose. Its colour iswhite.
