Magnoliids
Magnoliids (roughly translatable as " Magnolia similar to" even " magnoliid complex" ) is an informal English-language term used by botanists in 2009 the Angiosperm Phylogeny Group for a group of angiosperms, which represent the largest group within the basal orders. The group can also be conducted as a separate taxon, such as subclass Magnoliidae, but this has not happened in the APG III system of 2009.
Features
The species exhibit as the other basal orders on numerous characteristics that apply within the Bedecktsamigen flowering plants as a primitive. These include einfurchige ( monocolpate ) pollen, not grown together, so free carpels, a radially symmetrical structure of the flower and the presence of essential oils. Many trees, shrubs and herbaceous plants belong to this group.
System
The group designated as Magnoliids are four orders:
- Magnolia -like ( Magnoliales )
- Laurel -like ( Laurales )
- Canellales
- Pepper -like ( Piperales )
It is a monophyletic group, the relationship of the orders can be represented in the following cladogram:
Magnoliales
Laurales
Canellales
Piperales
Magnoliales and Laurales are sister taxa, as well as Canellales and Piperales. This is well supported by molecular biology, even if up to now for these two groups no shared derived characteristics ( synapomorphies ) are known.
