Related and similar species
Englerophytum magalismontanum [= Bequaertiodendron magalismontanum ], a small to medium-sized evergreen tree, has elliptic to narrowly obovate, dark green leaves usually densely covered with reddish brown to silvery hairs below and with rounded tips, and with flowers usually on short stalks and in compact clusters on young and old wood. Manilkara discolor can be confused with E. natalense but it is usually a bigger tree with rough bark, often growing in drier situations, and its leaf tips are usually more rounded.

Conservation status
Englerophytum natalense is not listed on the Tree Species Protected List in terms of National Forest Act 84 of 1998. In the Red Data List, this taxon was not selected in any one of four screening processes for highlighting potential taxa of conservation concern for detailed assessment and was hence given an automated status of Least Concern.

Distribution and habitat
Englerophytum natalense occurs from Eastern Cape northwards through KwaZulu-Natal and Swaziland, with isolated populations in Mpumalanga, eastern Zimbabwe and East Africa. It occurs in forest, particularly in subtropical areas, often in groves. In the understorey of dry riverine forest below the mistbelt, in mixed evergreen forest, ravine forest, coastal forest, often in groves, at forest margins, in clearings and in Afromontane forest.

Derivation of name and historical aspects
Englerophytum : Engler's tree, after Prof. H.G.A. Engler [1844–1930], German botanist and renowned authority on African plants; natalense from Natal, now KwaZulu-Natal (KZN).

Growing Englerophytum natalense

Grow it from seed. As a garden species this is an ideal small tree that will grow in partial to deep shade. It will not take any frost and is fairly slow growing. However, the slowness must not discourage you from using this species. A four metre tall tree can begin fruiting after about its sixth season. As a landscape feature use this species in groves or as a single accent specimen. Seed cleaned of its flesh will germinate fairly quickly in about two to three weeks after sowing. Pot them up into their own individual growing bags and wait for a few years. The plants respond well to feed and will grow well if given enough water, heat and food.
