The red beech is an excellent evergreen garden tree, quick growing and easily grown from seed. It attracts birds to a garden.
Evergree tree, up to 15 m tall, single-stemmed, with a dark, rounded crown. It tolerates slight frost and is very drought-resistant. Occasional bright red leaves make this an attractive garden specimen.
Bark is dark brown, smooth to rough. The Mango family does not have milky latex such as Moraceae (Fig family) or Sapotaceae (Milkwood family). Members of the Mango family have resin ducts (sticky latex but not milky).

The Mango family comprises mostly trees or shrubs; a few species produce useful, edible fruits such as mangoes, marulas and cashew and pistachio nuts.
The Red Data status of Protorhus longifolia is of Least Concern.
Distribution and habitat
It grows in coastal and montane forest, on rocky outcrops and in riverine vegetation, from Limpopo Province to the Eastern Cape.
Derivation of name and historical aspects
Protorhus – (Greek “protos” means first, “rhous” means red; there are often red leaves on the tree); longifolia – (Latin – refers to the long shape of the leaves).
Leaves are browsed by black rhino. Fruit are eaten by birds and animals, especially monkeys.
Uses and cultural aspects
The bark exudes a sticky gum which was used to stick the blade into the shaft when making assegais. The heartwood is dark brown and suitable for furniture. Sticky sap is used to remove hair. Powdered bark is poisonous and causes paralysis.
