Malvoideae is a subfamily within the plant family of the Mallow family (Malvaceae). The varieties of some species are used as ornamental plants .

description

Vegetative characteristics

They are mostly woody plants. The simple leaves have serrated or smooth edges.

Generative characteristics

Many genera have a secondary chalice. The hermaphroditic, five-fold flowers have a double flower envelope . In the subfamily Malvoideae, the many stamens have grown together to form a tube ( columna ) surrounding the pistil .

Systematics

The subfamily of the Malvoideae was set up in 1835 by Gilbert Thomas Burnett in Outlines of Botany , pp. 816, 1094, 1118 under the name "Malvidae".

The subfamily of the Malvoideae includes about 78 genera with about 1670 species. The species-richest genus within this subfamily is with about 550 species hibiscus ( Hibiscus ). The subfamily Malvoideae is divided into four tribes; two other genera are not assigned to any tribe:

  • Tribe Hibisceae: It contains about 27 to 30 genera:
    • Abelmoschus medic. : The approximately 15 species thrive in tropical and subtropical areas in the eastern hemisphere. Some species are called muskrat. This subheading includes B .:
      • Okra ( Abelmoschus esculentus (L.) Moench )
      • Cassava muskrat ( Abelmoschus manihot (L.) Medik. )
    • Anotea (DC.) Kunth : One or two species are found in Mexico.
    • Cenocentrum Gagnep. : It contains only one type:
    • Decaschistia Wight & Arn. : The two to ten species are common in tropical Asia.
    • Fioria Mattei : With up to four species that occur in Africa and Asia
    • Goethea Nees (incorporatedinto the genus Pavonia by some authors): With about two species in Brazil
    • Helicteropsis Hochr. : There are about two species in Madagascar.
    • Hibiscadelphus Rock : The four or so species are found in Hawaii .
    • Hibiscus ( Hibiscus L. ): Depending on the author, this genus contains 300 to over 500 species. The extent of this genus, which is called polyphyletic in most studies, is controversial.
    • Humbertianthus Hochr. : It contains only one type:
    • Humbertiella Hochr. : The three or so species occur in Madagascar.
    • Kosteletzkya C.Presl : The 30 or so species are common in the New World, Africa and Madagascar. One species also occurs in southern Europe:
    • Macrostelia Hochr. : About three species occur in Madagascar and one species in Queensland .
    • Malachra L .: The nine or so species are common in the Neotropic .
    • Malvaviscus Fabr .: The five or so species are common in the Neotropics.
    • Megistostegium Hochr. : The roughly three species found in Madagascar.
    • Papuodendron C.T.White : One or two species occur in New Guinea .
    • Pavonia Cav. : The extent of this genus is controversial, it contains about 150 species.
    • Peltaea (C.Presl) Standl. : The four or so species are common in the Neotropics.
    • Perrierophytum Hochr. : The approximately nine species occur in Madagascar.
    • Phragmocarpidium Krapov. : It contains only one type:
    • Radyera Bullock : Of the only two species, one occurs in Australia and the other in South Africa .
    • Rojasimalva Fryxell : it contains only one species:
    • Senra Cav. : It contains only one type:
    • Symphyochlamys Gürke : It contains only one species:
    • Talipariti Fryxell (alsocountedas part of Hibiscus by some authors): The 17 to 24 species are common in the tropics, mainly in Southeast Asia. Including:
    • Urena L .: The six or so species are distributed in tropical and subtropical areas, for example:
    • Wercklea Pittier & Standl. : The twelve species are common in the Neotropic.
  • Tribe Kydieae: It contains about four genera:
    • Dicellostyles Benth. : It probably contains only one species:
    • Julostylis Thwaites : The one to three species that occur in India and Sri Lanka.
    • Kydia Roxb. : The only two types are common in India, Bhutan , Myanmar, China, Cambodia and Vietnam.
    • Nayariophyton T.K.Paul : It contains only one species:
  • The two genera are not assigned to any tribe:
