Callitris glaucophylla is naturalized in Brevard, Indian River, Orange, and Seminole counties in Florida.
This inland Australian species is sometimes united with the eastern coastal Callitris columellaris F. Mueller under that name or distinguished at varietal rank (var. campestris Silba). The names C . glauca R. Brown ex R. T. Baker & H. G. Smith and C . hugelii (Carrière) Franco have been applied erroneously to it.
