Allosyncarpia ternata

Allosyncarpia ternata, commonly known as An-binik, is a species of rainforest trees constituting part of the botanical family Myrtaceae and included in the Eucalypts group. It is the only species described in its genus Allosyncarpia, in 1981 by Stanley Blake of the Queensland Herbarium. They grow naturally into large, spreading, shady trees, found only (endemic) in the Northern Territory of Australia. They grow in sandstone gorges along creeks emerging from the Arnhem Land plateau.[1]

Distribution and habitat[edit]

The tree dominates the closed monsoon rainforest communities along the sandstone escarpment of the western Arnhem Land Plateau. The distribution of the species appears to be limited to areas not subject to wildfire.[2]


Allosyncarpia dominated rainforest is an important vegetation community along the floristic boundary between the patches of monsoon forest that are sheltered from wildfire, and the fire-tolerant, eucalypt dominated, tropical savannas.[2]
