Searsia glauca (or the blue kuni-rhus) is a small, compact tree or bush native to the Cape Provinces of South Africa. [1] Although commonest near the coast, it is also found inland among fynbos vegetation. Searsia glauca has potential medicinal effects and antioxidant properties that can aid in the prevention of cell injury or death. [2] [3]

The leaves are characteristically glossy/shiny and often a slightly glaucous (blue-green) colour. The leaves are trifoliate, with three obtuse (obcordate-cuneate) leaflets.

It is dioecious, with male and female flowers on separate plants. [4] The fruits reach a maximum diameter of 5 mm (distinguishing it from Searsia undulata which has 3mm fruits). [5]

Distribution

This species occurs along the coast of South Africa, as well as in certain areas inland. It occurs from Velddrif and Cape Town in the west, eastwards into the Eastern Cape Province.

Inland it occurs in the Little Karoo, around Worcester, Oudtshoorn, Baviaanskloof and northwards into Zimbabwe. [4]

The Douglas fir is an evergreen conifer species in the pine family, Pinaceae. It is native to western North America and is also known as Douglas-fir, Douglas spruce, Oregon pine, and Columbian pine. There are three varieties: coast Douglas-fir, Rocky Mountain Douglas-fir and Mexican Douglas-fir.

<span class="mw-page-title-main">Fynbos</span> Shrubland and heathland ecoregion of southwestern South Africa

Fynbos is a small belt of natural shrubland or heathland vegetation located in the Western Cape and Eastern Cape provinces of South Africa. This area is predominantly coastal and mountainous, with a Mediterranean climate and rainy winters. The fynbos ecoregion is within the Mediterranean forests, woodlands, and scrub biome. In fields related to biogeography, fynbos is known for its exceptional degree of biodiversity and endemism, consisting of about 80% species of the Cape floral kingdom, where nearly 6,000 of them are endemic. This land continues to face severe human-caused threats, but due to the many economic uses of the fynbos, conservation efforts are being made to help restore it.

<i>Adansonia</i> Genus of plants known as baobab

Adansonia is a genus made up of eight species of medium-to-large deciduous trees known as baobabs. They are placed in the Malvaceae family, subfamily Bombacoideae. They are native to Madagascar, mainland Africa, and Australia. The trees have also been introduced to other regions such as Asia. The generic name honours Michel Adanson, the French naturalist and explorer who described Adansonia digitata. The baobab is also known as the "upside down tree", a name that originates from several myths. They are among the most long-lived of vascular plants and have large flowers that are reproductive for a maximum of 15 hours. The flowers open around dusk, opening so quickly that movement can be detected by the naked eye, and are faded by the next morning. The fruits are large, oval to round and berry-like and hold kidney-shaped seeds in a dry, pulpy matrix.

<i>Searsia pendulina</i> Species of tree

Searsia pendulina, commonly known as the white karee (English) or witkaree (Afrikaans), is a hardy, very fast growing, semi-deciduous tree. It is native to Namibia and to the Free State and Cape Provinces of South Africa. It occurs naturally along the Orange River and some of its tributaries.

<i>Searsia dentata</i> Species of tree

Searsia dentata, the nana-berry (English), or nanabessie (Afrikaans), is a medium-sized, deciduous tree, reaching a height of about 5 metres and a spread of 4 metres, and with a tendency to scramble through and over neighbouring trees. It occurs naturally in almost the whole of South Africa except the Western and Northern Cape Provinces. Its habitat varies from sea level to the highlands of the Drakensberg. It is frost-hardy and should be planted in full sun. The strongly aromatic leaves are usually conspicuously toothed, though sometimes they may be only slightly toothed. The tree produces small, creamy-white flowers in masses, developing into small, flattened drupes (5-6mm) which turn red or orange when ripe and brown when dry. The ripe fruits are eaten by birds, while the foliage is food for the larvae of the pepper tree moth Bombycomorpha bifascia.

<i>Searsia lancea</i> Species of tree belonging to the cashew and sumac family

Searsia lancea commonly known as karee, is an evergreen, frost hardy, drought resistant tree, which can reach up to 8 metres in height with a 5-metre spread.

In North America, where it is naturalized, it is known as African sumac and willow rhus.

<i>Searsia pentheri</i> Species of tree endemic to eastern South Africa and southern Mozambique

Searsia pentheri, the common crowberry (English), gewone kraaibessie (Afrikaans), iNhlokoshiyane (Zulu), or mutasiri (Venda), is a species of tree in the genus Searsia. Frost hardy tree reaching a height of up to 6 metres. The tree is mainly evergreen but loses its leaves in severe winters. It has olive-green foliage with dark brown bark and can be grown in either full sun or semi shade. Small flowers are produced and are followed by masses of shiny, light brown, small edible fruits, which provide a feast for birds. Only female trees produce these fruits though. The tree occurs over large portions of South Africa. It has been planted in Spain.

It is a dioecious tree that often forms root suckers and has fissured and scaly bark, spreading or drooping branchlets, the leaves reduced to scales in whorls of 12 to 20, the fruit 9–18 mm (0.35–0.71 in) long containing winged seeds (samaras) 3.5–5.0 mm (0.14–0.20 in) long.

<i>Brabejum</i> Monotypic genus of trees in the family Proteaceae from the Western Cape of South Africa

Brabejum is a genus of a single species of large evergreen tree, Brabejum stellatifolium in the family Proteaceae, commonly called wild almond, bitter almond or ghoeboontjie. It is restricted in the wild to South Africa's Western Cape province, where it grows in thickets along the banks of streams. The plant is of botanical interest as being Africa's only member of the large grevilleoid subfamily. It is a bushy small tree with branches widely at ground level and numerous erect vigorous stems. Leaves grow up to 6 in (15 cm) long, narrow and bluntly toothed, appear at intervals along the branches, mostly in whorls of 6. In summer, the plant bears white flowers densely crowded on spikes arising from rusty buds at the leaf axils. The fruits to 2 in (5 cm) long, magenta to reddish brown, similar to an almond, appear in autumn. The nut is too bitter to eat; however, in earlier times it was boiled, roasted, and ground to make a "coffee" drink.
