Scientific name: Baloghia marmorata
Profile last updated:
13 Oct 2021
Description
Jointed Baloghia is a shrub or small tree growing up to 8 m tall. The bark is greenish-cream, smooth or slightly vertically fissured. Leaves are 6.5 – 15 cm long, tapering at both the tips and the bases, and green and glossy on both surfaces. A pair of glands is situated on the margin of the leaf about 5 mm above the stalk, this makes the leaf appear jointed at the stem. Small white flowers are borne in clusters at the tips of side shoots. Fruits are fawn capsules about 2 cm in diameter, containing two to four dark-red and cream spotted seeds.
Distribution
Known only from the Lismore district in north-east NSW and the Tamborine Mountains and Springbrook area in south-east Queensland.
Habitat and ecology
- In NSW, Jointed Baloghia is found in subtropical rainforest, notophyll vine forest and wet sclerophyll forest on soils derived from basalt.
- Found between 150m and 550m above sea level.

Threats
- Clearing and fragmentation of habitat for agricultural development.
- Clearing and fragmentation of habitat for urban development.
- Fragmentation and clearing of habitat for road works.
- Risk of local extirpation because populations are small .
- Inappropriate fire regimes can result in loss of individuals and alteration of habitat.
- Infestation of habitat by introduced weeds.
- Trampling by visitors to rainforest remnants.
- Risk of local extirpation because distribution is restricted.
- Declining genetic variability as a result of small, fragmented populations.
Recovery strategies
Priority actions are the specific, practical things that must be done to recover a threatened species, population or ecological
community. The Office of Environment and Heritage has identified
16 priority actions
to help recover the Jointed Baloghia in New South Wales.
Activities to assist this species
- Support local Landcare groups and bush regeneration teams rehabilitate known habitat.
- Stay on tracks when visiting rainforest areas.
- Control weeds in rainforest areas.
- Protect areas of rainforest habitat from, timber harvesting activities, clearing and development.
- Expand and connect remaining remnants of habitat.
- Report new records of Jointed Baloghia to theOEH.
- Ensure appropriate fire regime for the habitat is implemented. This may include the exclusion of fire.
- Undertake research into ecological requirements including the impact of fire.
- Investigate seed viability and vegetative propogation techniques.
- Maintain viable ex-situ seedbank.
