Plectranthus hadiensis is a perennial herbaceous plant of the family Lamiaceae.
Plectranthus hadiensis is a perennial herbaceous shrub with pubescent and semi-succulent stems, and a straight to decumbent habit. Its height varies 50 cm to 1.5 m (30–59 in), with a maximum base diameter of 1m (39 in). The leaves of the plant are arranged alternately on the plant's stem, they have coarse textures; an ovate shape; densely woolly-tomentose; are apex acute to rounded, cuneate with subcordate base; and a superficial to fairly crenate-dentate margin. The petiole is 10 to 40 mm long. The terminal inflorescences of the plant are simple and have 1 to 2 pairs of lateral branches near the base. The flowers of the plant are generally in shades of mauve to purple (occasionally white), and are bilabiated with a tube-shaped corolla of 8 to 15 mm that widens from the base, finely pubescent and with glands on the lips.
There are three varieties of P. hadiensis:
The species is found in Transkei, Natal, Eswatini, the Transvaal, eastern tropical Africa, Somalia and the southern Arabian Peninsula. The plant can be found on the fringes of forests, in dry forests and amongst rocks in grasslands and lowlands. [2]
Plectranthus hadiensis is widely used as an ornamental plant because it is easy to cultivate, propagate and maintain. The compounds of the plant were formerly used to poison fish and more traditionally as an enema. It is used to ward off evil spirits. In Uganda it is used to heal wounds and peptic ulcers
The plant's use as a pharmacological agent is being investigated as it contains large quantities of essential oils, it is also being investigated for use against respiratory infections.[ citation needed ] However, ointments made with compounds extracted from the plant must not contain menthol, camphor or eucalyptus. [3]
Plectranthus hadiensis was discovered by Peter Forsskål in Hadiyah, Yemen. It was described in Flora of Egypt and Arabia in 1775 with the name Ocimum hadiensis. At that time the genus Plectranthus had not been established, however it was the first species of the genus described and in 1894 the botanists Schweinfurth and Sprenger transferred it to the new genus, publishing it in Wiener Illustrirte Garten-Zeitung 19: 2. 1894.

Coleus amboinicus, synonym Plectranthus amboinicus, is a semi-succulent perennial plant in the family Lamiaceae with a pungent oregano-like flavor and odor. Coleus amboinicus is considered to be native to parts of Africa, the Arabian Peninsula, and India, although it is widely cultivated and naturalized elsewhere in the tropics where it is used as a spice and ornamental plant. Common names in English include Indian borage, country borage, French thyme, Indian mint, Mexican mint, Cuban oregano, soup mint, Spanish thyme. The species epithet, amboinicus refers to Ambon Island, in Indonesia, where it was apparently encountered and described by João de Loureiro (1717–1791).
Kniphofia is a genus of perennial flowering plants in the family Asphodelaceae, first described as a genus in 1794. All species of Kniphofia are native to Africa. Common names include tritoma, red hot poker, torch lily and poker plant.
Plectranthus is a genus of about 85 species of flowering plants from the sage family, Lamiaceae, found mostly in southern and tropical Africa and Madagascar. Common names include spur-flower. Plectranthus species are herbaceous perennial plants, rarely annuals or soft-wooded shrubs, sometimes succulent; sometimes with a tuberous base.
Plectranthus verticillatus, Swedish ivy, Swedish begonia or whorled plectranthus is a plant in the family Lamiaceae (Labiatae), genus Plectranthus. Despite its common name, it is not close to the ivy family of the genus Hedera.
The Kwazulu-Cape coastal forest mosaic is a subtropical moist broadleaf forest ecoregion of South Africa. It covers an area of 17,800 square kilometers (6,900 sq mi) in South Africa's Eastern Cape and KwaZulu-Natal provinces.
The Maputaland coastal forest mosaic is a subtropical moist broadleaf forest ecoregion on the Indian Ocean coast of Southern Africa. It covers an area of 29,961 square kilometres (11,568 sq mi) in southern Mozambique, Eswatini, and the KwaZulu-Natal Province of South Africa. Mozambique's capital Maputo lies within the ecoregion.
Areas of forest which grow in KwaZulu-Natal, South Africa mostly on south facing slopes in higher rainfall areas, and along the humid coastal areas. Different types of forest can be identified by their species composition which depends mostly on the altitude, latitude and substrate in which they grow. South facing slopes are favourable for the development of forest as they are more shaded, and therefore cooler and retain more moisture than the northern slopes. The extra moisture on the south slopes is not only favoured by forest trees, but also helps to prevent or subdue wildfires. Fires can also be blocked by cliff faces and rocks or boulders on these slopes, and by streams or rivers at the base of the slopes. The coastal regions are conducive to forest formation, because of high rainfall and humidity which are favoured by forest trees and also help to prevent or subdue fires. The rivers of the coastal areas are also broader than further inland, which may often prevent fires from spreading long distances, and fires generally burn uphill and therefore more often away from areas at low altitude.
The Maputaland-Pondoland-Albany Hotspot (MPA) is a biodiversity hotspot, a biogeographic region with significant levels of biodiversity, in Southern Africa. It is situated near the south-eastern coast of Africa, occupying an area between the Great Escarpment and the Indian Ocean. The area is named after Maputaland, Pondoland and Albany. It stretches from the Albany Centre of Plant Endemism in the Eastern Cape Province of South Africa, through the Pondoland Centre of Plant Endemism and KwaZulu-Natal Province, the eastern side of Eswatini and into southern Mozambique and Mpumalanga. The Maputaland Centre of Plant Endemism is contained in northern KwaZulu-Natal and southern Mozambique.
Isoglossa woodii, commonly known as buckweed, is a monocarpic shrub of the family Acanthaceae, growing up to 4 m tall. It grows in colonies in coastal forest areas of KwaZulu-Natal and marginally into Eastern Cape and Free State of South Africa.
Millettia grandis is a species of plant in the family Fabaceae from South Africa. It is commonly called umzimbeet which is a name derived from the isiZulu name umSimbithwa.
KwaZulu-Natal Dune Forest is a subtropical forest type that was once found almost continuously along the coastal dunes of KwaZulu-Natal, South Africa. This vegetation type develops in sheltered areas behind the littoral zone, where with some protection from the salt wind it may develop with canopies as tall as 30 m. It still exists in protected areas, but much has been degraded by human activity. Coastal dune forest covers approximately 1% of the land area of KwaZulu-Natal, and is a habitat type seriously threatened from human population pressure and development, particularly titanium mining.
Deinbollia oblongifolia is a shrub or small tree in the family Sapindaceae. It is commonly known as the dune soap-berry and is found in coastal vegetation from the Eastern Cape of South Africa, through KwaZulu-Natal to southern Mozambique and Eswatini. It is named after Peter Vogelius Deinboll (1783–1876), a Danish botanist and plant collector.
Mikania natalensis, the Natal mikania, is a plant in the family Asteraceae, and is native to Africa.
Searsia chirindensis is a medium-sized, semi-deciduous, trifoliate Southern African dioecious tree of up to 10 m tall, rarely 20 m, often multi-stemmed, occurring along the coastal belt from the Cape, through KwaZulu/Natal, Eswatini, Zimbabwe and Mozambique as far north as Tanzania, and growing in a wide variety of habitats such as open woodlands, in forests, along forest margins, in the open, among rocks and on mountain slopes. It was named by Swynnerton from a specimen collected by him near the Chirinda Forest in the Chipinge District of Southern Rhodesia. This is one of more than a hundred southern African species in the genus. It is commonly known as red currant because of a fancied resemblance of the fruit to that of the European redcurrant.
