Nowadays, when small gardens are the order of the day, this lovely little multistemmed shrub has been overlooked as a potential form plant for that special corner or focal point.

Searsia magalismontana subsp. magalismontana is a multistemmed, evergreen, dwarf shrub, 150-500 mm high. Depending on the habitat it is found in, it can have the same spread or more. It grows from a woody rootstock wedged between rocky crevices. The young growth on the plant is often bronze, coral pink or red with numerous brownish dots, whereas the old stems are brown.

The leaves are trifoliolate (bearing three leaflets), erect, leathery, grey-green, very rigid when mature, and are very conspicuous from early spring to late summer. The venation is very prominent, and the stalks may be winged when the plant is young.

As is usual for this genus, there are separate male and female plants. The flowers are minute, creamy yellow and occur in dense sprays from October to November.

The fruit is yellowish, turning red when ripe from November to December and is slightly flattened.

Conservation status
The bergtaaibos is widespread. Gauteng Nature Conservation has adopted a policy to protect natural ridges, and this will ensure the protection of this species from decline in future.

Distribution and habitat
This species is widespread on hillsides and ridges in grassland and bushveld and often occurs in dense stands in the following provinces: Limpopo, North-West, Gauteng, Mpumalanga, KwaZulu-Natal, Eastern Cape and the Northern Cape at altitudes ranging from 1 000 to ± 2 000 m.

Derivation of name and historical aspects
The old genus name Rhus was derived from the Greek word, rhous, for sumach, and from rhodos, meaning red, and it most probably refers to the red fruits or autumn leaves of some of the species; the species name magalismontana refers to it being discovered originally in the Magaliesberg Mountain Range.

The new name Searsia originally featured in a footnote to a key to the genera of the Anacardiaceae family where Barkley (1942) stated 'Searsia n.gen. = (Rhus) Section Gerontogeae' and named it after Paul B. Sears.' Sears later became a well-known ecologist, palaeontologist and head of the Yale School of Botany. This publication was illegitimate as it contained no description of the genus. The next year when Searsia appeared as genus six in the Flora of Texas, it was corrected, fully described and included the cultivated South African Searsia lancea (L.f) F.A.Barkley (1943) where he made the new combination of S. tomentosa, and designated it as the type species. Nineteen more combinations in Searsia were made between 1950 and 1965.

Barkley (1965) criticised the traditional concept of the genus Rhus and his view was vindicated as research between 2001-2006 on the generic status of Rhus provided evidence that the Old World species of Rhus are significantly different to justify a generic status of their own (Moffett 2007).

The very small flowers are pollinated by insects and the red fruits attract many fruit-eating birds which is an asset to any garden.

Uses and cultural aspects
Not much is known about this plant and no knowledge exists that indicates that it has been or is still used culturally for anything.

Growing Searsia magalismontana subsp. magalimontana

Collect ripe fruit, clean and sow the seeds in November-December in sandy loam soil. The plant is very hardy and can tolerate frost as it grows on very exposed rocky areas. It is drought resistant and does not require a lot of water as can be seen from the habitat photograph included. This is definitely a small shrublet that can be used more in gardens especially in a rockery.
