Callitris columellaris is a species of coniferous tree in the family Cupressaceae (cypress family), native to most of Australia. Common names include White Cypress-pine, Murray River Cypress-pine, and Northern Cypress-pine. "Callitris columellaris" has been naturalised in Hawaii and in southern Florida. Using only the above description and what you know about the world, "The coniferous tree is continuing its naturalization expansion to other continents besides North America and Australia." is definitely correct, incorrect, or inconclusive?
