Food source for:
Toxicity:No toxicity known
Origin:Northeast Queensland
Weed:Yes
Weed status:Environmental/garden escapee
Notes:Spread by: Seeds wind borne over short distances, water, garden waste, stingless bees. Invades: Bushland outside its natural range.
Notes: Natural distribution is restricted to rainforest and tall open forest in narrow coastal belt in far north Queensland. Promoted and extensively planted as an ornamental amenity tree for decades, now widely naturalised and recorded in open forests and Melaleuca forests in this region. Known to hybridise with related species which has the potential for the original parent species to be completely replaced by hybrids.

Susceptible to sooty mould; inhibits germination of other species within close proximity and causes concern to keepers of native stingless bees.
