Davidsonia johnsonii1

Davidsonia johnsonii, commonly known as the Smooth Davidson's Plum or Johnsons's Davidsonia, is a rare fruit tree native to a limited area in Australia. It belongs to the family Cunoniaceae and is one of the three species in the genus Davidsonia. This species is distinguished by its smooth leaves and the unique flavor of its fruit, which has gained culinary interest in recent years.

Description

Davidsonia johnsonii is a small to medium-sized tree that can reach up to 10-15 meters in height. It has smooth, glossy leaves that are different from the other Davidsonia species, which have more textured leaves. The tree produces small, creamy-white flowers that are followed by large, purple-black fruits. The fruit is similar in appearance to a plum and contains a fibrous pit.

Distribution and Habitat

Davidsonia johnsonii is endemic to a restricted area in northern New South Wales, Australia. It grows in subtropical rainforests at altitudes ranging from 100 to 800 meters. The species prefers well-drained, fertile soils and is often found in the understory of dense forest areas.

Cultivation and Uses

While not as widely cultivated as its relatives, Davidsonia johnsonii is grown for its fruit, which is used in a variety of culinary applications. The fruit's tart flavor makes it suitable for jams, jellies, sauces, and desserts. It is also used in the production of wine and vinegar. Cultivation of Davidsonia johnsonii requires a moist, subtropical climate and protection from strong winds. The tree is propagated from seed or cuttings and begins to bear fruit after several years.

Conservation Status

Davidsonia johnsonii is considered rare and is listed as a vulnerable species. Its limited distribution and the fragmentation of its habitat pose significant threats to its survival. Conservation efforts are focused on habitat protection and the promotion of cultivation to reduce pressure on wild populations.
