[2][3][4] This species was first described in 1940 by William Blakely who gave it the name Phebalium buckinghamii and published the description in The Australian Naturalist.

[6] The specific epithet (buckinghamii) honours "Mr. William J. Buckingham of Lindfield, New South Wales".

[4] Asterolasia buckinghamii grows in gullies and on river flats or on slopes near cliff tops.

It occurs in the Wingello district and between Mittagong and Lithgow in New South Wales.
