Hibiscus sp.

Hibiscus is a genus of flowering plants in the mallow family, Malvaceae. The genus is quite large, comprising several hundred species that are native to warm temperate, subtropical and tropical regions throughout the world. Member species are renowned for their large, showy flowers and those species are commonly known simply as "hibiscus", or less widely known as rose mallow. Other names include hardy hibiscus, rose of sharon, and tropical hibiscus.

The genus includes both annual and perennial herbaceous plants, as well as woody shrubs and small trees. The generic name is derived from the Greek name ἰβίσκος (ibískos) which Pedanius Dioscorides gave to Althaea officinalis (c. 40–90 AD).

Several species are widely cultivated as ornamental plants, notably Hibiscus syriacus and Hibiscus rosa-sinensis.

A tea made from hibiscus flowers is known by many names around the world and is served both hot and cold. The beverage is known for its red colour, tart flavour, and vitamin C content.

Description

The leaves are alternate, ovate to lanceolate, often with a toothed or lobed margin (dentate). The flowers are large, conspicuous, trumpet-shaped, with five or more petals, colour from white to pink, red, blue, orange, peach, yellow or purple, and from 4–18 cm broad.

 

Flower colour in certain species, such as H. mutabilis and H. tiliaceus, changes with age. The fruit is a dry five-lobed capsule, containing several seeds in each lobe, which are released when the capsule dehisces (splits open) at maturity. It is of red and white colours. It is an example of complete flowers.

Stigma

 

The yellow hibiscus is the state flower of Hawaii, although the most commonly seen hibiscus in the state is Hibiscus rosa-sinensis.

In temperate zones, probably the most commonly grown ornamental species is Hibiscus syriacus, the common garden hibiscus, also known in some areas as the "rose of Althea" or "rose of Sharon" (but not to be confused with the unrelated Hypericum calycinum, also called "rose of Sharon"[10]). In tropical and subtropical areas, the Chinese hibiscus (H. rosa-sinensis), with its many showy hybrids, is the most popular hibiscus.

Several hundred species are known, including:

• Hibiscus abelmoschus L. synonym of Abelmoschus moschatus Medik.[11]
• Hibiscus abelmoschus var. betulifolius Mast. synonym of Abelmoschus moschatus Medik.[12]
• Hibiscus abelmoschus var. genuinus Hochr. synonym of Abelmoschus moschatus Medik.
