'''Proteales''' is an order of flowering plants. It includes three families, namely [[Proteaceae]], [[Platanaceae]], and [[Nelumbonaceae]], with a total of about 75 genera and nearly 1600 species. The order is recognized by most taxonomists and is placed in the [[eudicots]] clade in the [[Angiosperm Phylogeny Group]] classification.

== Taxonomy ==
'''Proteales''' is an order of flowering plants belonging to the [[eudicots]], one of the major groups of [[angiosperms]]. This order includes several families, the most notable being the [[Proteaceae]], [[Nelumbonaceae]], and [[Platanaceae]].


The Proteales order is part of the [[Rosids]] clade, which is itself part of the larger [[Eudicots]] clade. The order is further divided into three families: Proteaceae, Platanaceae, and Nelumbonaceae.
==Characteristics==
Proteales are diverse in form and habitat, ranging from trees and shrubs to aquatic plants. Members of this order are found in a variety of environments, from tropical to temperate regions.


=== Proteaceae ===
===Proteaceae===
[[File:Protea_cynaroides_3.jpg|thumb|left|''Protea cynaroides'', the king protea]]
The family [[Proteaceae]] is well known for its unique and often spectacular flowers. It includes genera such as ''[[Protea]]'', ''[[Banksia]]'', and ''[[Macadamia]]''. These plants are primarily found in the Southern Hemisphere, particularly in [[Australia]] and [[South Africa]].


The [[Proteaceae]] family is the largest within the Proteales order, with about 80 genera and 1600 species. This family is primarily distributed in the Southern Hemisphere and is particularly diverse in Australia and South Africa.
===Nelumbonaceae===
The family [[Nelumbonaceae]] consists of aquatic plants, most notably the [[lotus]] (''[[Nelumbo nucifera]]''). These plants are characterized by their large, showy flowers and peltate leaves.


=== Platanaceae ===
===Platanaceae===
The family [[Platanaceae]] includes the [[plane trees]], such as the [[London plane]] (''[[Platanus _ acerifolia]]''). These are large trees commonly found in urban areas due to their resilience and ability to withstand pollution.


The [[Platanaceae]] family, also known as the plane tree family, consists of a single genus, Platanus, with about 10 species. These trees are native to the Northern Hemisphere and are commonly found in North America and Eurasia.
==Distribution==
Proteales are distributed worldwide, with a significant presence in the Southern Hemisphere. The [[Proteaceae]] family is predominantly found in [[Australia]] and [[South Africa]], while the [[Nelumbonaceae]] are native to [[Asia]] and [[North America]]. The [[Platanaceae]] are found in the Northern Hemisphere, particularly in [[North America]] and [[Europe]].


=== Nelumbonaceae ===
==Ecological Importance==
Members of the Proteales order play important roles in their ecosystems. The [[Proteaceae]] are key components of the [[fynbos]] biome in South Africa and the [[sclerophyll]] forests of Australia. The [[Nelumbonaceae]] provide habitat and food for aquatic wildlife, while the [[Platanaceae]] are important for urban greening.


The [[Nelumbonaceae]] family, also known as the lotus family, consists of a single genus, Nelumbo, with two species. These aquatic plants are native to North America and Asia.
==Evolutionary Relationships==
Proteales are part of the [[eudicots]], a clade that includes most of the flowering plants. Molecular studies have helped clarify the relationships within this order, showing that the [[Proteaceae]] and [[Nelumbonaceae]] are more closely related to each other than to the [[Platanaceae]].


== Evolution ==
==Related pages==
 
The Proteales order is considered to be one of the earliest diverging lineages of the eudicots. Fossil evidence suggests that the Proteales originated in the late Cretaceous period, around 89.8 million years ago.
 
== Economic Importance ==
 
Several species within the Proteales order have significant economic importance. For example, some species of the Proteaceae family, such as the [[Macadamia]] nut, are cultivated for their edible seeds. The wood of plane trees (Platanaceae) is used in furniture making, and the lotus (Nelumbonaceae) is cultivated for its edible seeds and rhizomes, as well as for ornamental purposes.

Order of flowering plants



Proteales is an order of flowering plants belonging to the eudicots, one of the major groups of angiosperms. This order includes several families, the most notable being the Proteaceae, Nelumbonaceae, and Platanaceae.

Characteristics[edit]

Proteales are diverse in form and habitat, ranging from trees and shrubs to aquatic plants. Members of this order are found in a variety of environments, from tropical to temperate regions.

Proteaceae[edit]

Protea cynaroides, the king protea

The family Proteaceae is well known for its unique and often spectacular flowers. It includes genera such as Protea, Banksia, and Macadamia. These plants are primarily found in the Southern Hemisphere, particularly in Australia and South Africa.

Nelumbonaceae[edit]

The family Nelumbonaceae consists of aquatic plants, most notably the lotus (Nelumbo nucifera). These plants are characterized by their large, showy flowers and peltate leaves.

Platanaceae[edit]

The family Platanaceae includes the plane trees, such as the London plane (Platanus _ acerifolia). These are large trees commonly found in urban areas due to their resilience and ability to withstand pollution.

Distribution[edit]

Proteales are distributed worldwide, with a significant presence in the Southern Hemisphere. The Proteaceae family is predominantly found in Australia and South Africa, while the Nelumbonaceae are native to Asia and North America. The Platanaceae are found in the Northern Hemisphere, particularly in North America and Europe.

Ecological Importance[edit]

Members of the Proteales order play important roles in their ecosystems. The Proteaceae are key components of the fynbos biome in South Africa and the sclerophyll forests of Australia. The Nelumbonaceae provide habitat and food for aquatic wildlife, while the Platanaceae are important for urban greening.

Evolutionary Relationships[edit]

Proteales are part of the eudicots, a clade that includes most of the flowering plants. Molecular studies have helped clarify the relationships within this order, showing that the Proteaceae and Nelumbonaceae are more closely related to each other than to the Platanaceae.
