Englerophytum magalismontanum, commonly known as stamvrug, is an evergreen tree that mostly grows in rocky places.

Their bisexual flowers are similarly crowded on the trunk and branches, and smell strongly of fermenting honey.

Stamvrug trees at maturity may range from 1 metre tall on exposed dip slopes with very limited soil where they are prone to stunting by fire, to about 15 metres in the shelter of kloofs (gorges) with ample water and deep soil.

The species is a larval food plant for the butterfly Pseudacraea boisduvali trimeni.

It belongs to the family Sapotaceae with some 35 genera and 600 odd species, that are mostly trees with leathery, entire leaves.
