The broad-leaved stone yew ( Podocarpus latifolius ) is a type of plant from the genus of stone slices ( Podocarpus ) within the family of stone slices (Podocarpaceae). It is native to South Africa (especially in afromontane forests ) and is called Yellowwood there; In German-speaking South Africa travel guides it is therefore referred to as the "Yellowwood tree".

description

The broad-leaved stone slice is a slow-growing evergreen tree and reaches heights of up to 35 meters with trunk diameters of up to 3 meters. The leaves are striped and about 3 to 4 cm long, on young trees sometimes up to 10 cm long and about 6 to 12 mm wide. The fresh leaf shoot is light green, while the older foliage is dark green.

The broad-leaved stone disk is dioeciously separated sexes ( diocesan ). The seeds, coated by an aril, ripen in December to February; the aril then turns purple. The aril is edible and tastes sweet.

The hard, yellow-colored wood of this type is very popular; by overuse in the past, the natural deposits have been significantly reduced.
