Lophostemon grandiflorus is a member of the family Myrtaceae endemic to Western Australia, the Northern Territory[1] and Queensland.

Epiphytic and parasitic plants are often found growing on the bark.

The thick, ovate and dark green leaf blades are about 5 to 12 centimetres (2.0 to 4.7 in) in length and 2 to 6.5 cm (0.79 to 2.56 in) wide.

It usually grows as a rheophyte along creeks through open forest, but is also found on the margins of rainforests.

[2] It is found in damp areas such as riverbanks and sandstone gorges in the Kimberley region of Western Australia[1] across the top end of the Northern Territory and then down the east coast as far as Central Queensland.
