Sapindales: Facts and details from Encyclopedia Topic(Site not responding. Last check: 2007-10-20)
The Sapindales is an order of flowering plant[For more info, click on this link]s included among the rosid subgroup of dicotyledon[Click link for more facts about this topic]s.
The simaroubaceae are a small family in the order sapindales, including trees such as ailanthus....
The zygophyllaceae are a family of about 250 species of dicotyledonous plants also known as the bean-caper or caltrop family....
These are usually distinguished by others as the Sapindales, the Rutales, the Burserales, and the Zygophyllales to use the nomenclature employed by Takhtajan (1997).
Taking Cronquist's Sapindales as the model taxon, the comparison table shows the distribution of the several families, orders and superorders adopted by Reveal, Takhtajan and Thorne from the Sapindales.
As may be seen, these are the central problem of Cronquist's Sapindales for there is obvious minimal agreement as what should or should not be circumscribed in almost any one of the taxa.
As differentiated in his 1981 key to the orders, the Geraniales are those members of the subclass with mostly compound or conspicuously lobed leaves, syncarpous carpels resulting in a superior ovary bearing distinct styles, and typically actinomorphic and hypogynous flowers with 1-2 (3) times the number of free stamens as petals.
Cronquist inserts the Sapindales between his Polygalales and Geraniales whereas the others remove the whole of the Sapindales to their Rutanae, with Thorne reducing the Sapindales to synonymy under his Rutales.
This arrangement is broadly support by the rbcL data, with the exception of the Capparanae which are position in the middle of what might be termed the Rutanae/Geranianae complex and the Linales are well removed being closer to the Euphorbiales than the Geraniales.
Anacardiaceae and Burseraceae have been recognized as representatives of Sapindales but only as distantly related within the order.
Recent molecular phylogenies have confirmed their position in Sapindales and the monophily of the both families is well supported, and in addition, Anacardiaceae and Burseraceae were found to be sister groups.
It is expected in the end to find new morphological synapomorphies of these families in regard to others Sapindales.
No preventative has yet been found for the disease, which may possibly be caused by a leafhopper-borne mycoplasma.
common name for the family Meliaceae, of the order Sapindales, comprising a medium-size group (about 550 species in about 50 genera) of tropical trees and shrubs important for high-quality woods.
common name for the family Aceraceae, order Sapindales, comprising a small group of trees widespread in the temperate areas of the northern hemisphere, and for its representative genus, Acer.
Although previously associated with Geraniaceae, molecular data place it in Sapindales, albeit with a long branch (Bakker et al.
Nitraria often has two or three leaves at a node, although not all these have scarious stipules; the leaves are occasionally toothed or lobed.
Molecular data suggest the relationships (((Peganum + Malacocarpus) Tetradiclidium) Nitraria) (Sheahan and Chase 1996), and assign the group to Sapindales.
It has about the same number of species as the subclass Asteridae.
Five orders, Fabales (14,000 species) Myrtales (9000 species), Euphorbiales (7600 species), Rosales (6600 species) and Sapindales (5400 species), contain about 75% of the species in the subclass.
A diverse and almost certainly paraphyletic group, the Rosales is difficult to characterize.
