Coat of arms and country name in Afrikaans and English.

The coat of arms was granted by King George V by Royal Warrant on 17 September 1910, few months after the formation of the Union of South Africa.

It was a combination of symbols representing the four provinces (formerly colonies) that made up the Union:
• The first quarter is the figure of Hope, representing the Colony of the Cape of Good Hope.
• The two wildebeests of the second quarter represent the Colony of Natal.
• The orange tree in the third quarter was used as the symbol of the Orange Free State Republic.
• The wagon in the fourth quarter represented the Transvaal.
• The supporters are taken from the arms of the Orange River Colony and the Cape Colony.
• The lion holds four rods, bound together, symbolizing the unification of the four former colonies.

The motto, Ex Unitate Vires was officially translated as "Union is Strength" until 1961, and thereafter as "Unity is Strength".

Obverse engraver initials varieties exist:
• 1970-1983: T.S. below base of the coat of arms right-hand side (Tommy Sasseen)
• 1984: no engraver initials (Arthur Sutherland)
• 1985-1989: A.L.S. below base of the coat of arms left-hand side (Arthur Sutherland)

Depicts three flowers, all native to South Africa, from left to right Arum Lily, Agapanthus and Strelitzia.

The Arum Lily (Zantedeschia Aethiopica) is a distinguished South African flower. It is also known as the white calla lily, aronskelk or varkblom (pig lily). The latter name is due to the fact that the plant’s nutritious rootstock is favoured by pigs and to some extent by porcupines. The plant is also used medicinally in various ways. The white Arum Lily can be evergreen or deciduous, depending on how much water is gets. The spathe (flower) varies in colour from white to cream and a green and white variation is also found in semi shaded areas.

Agapanthus are commonly known as lily of the Nile (or African lily in the UK), although they are not lilies and all of the species are native to Southern Africa (South Africa, Lesotho, Swaziland, Mozambique).

Strelitzia is a genus of five species of perennial plants, native to South Africa. The genus is named after the duchy of Mecklenburg-Strelitz, birthplace of Queen Charlotte of the United Kingdom. A common name of the genus is bird of paradise flower / plant, because of a resemblance of its flowers to birds-of-paradise. In South Africa it is commonly known as a crane flower.

This flower design was modelled by Tommy Sasseen from a drawing by Cynthna Letty.
