Eucalyptus sparsa is a mallee that typically grows to a height of 3–10 m (9.8–32.8 ft) and forms a lignotuber.

[3][4][5][6] Eucalyptus sparsa was first formally described in 1979 by Clifford David Boomsma near Betty's Creek Gorge in the Everard Ranges in 1974.

[8] The northern ranges box grows on sand dunes and on plains and slopes on well-drained soil.

[4][5] This mallee is classified as "Priority Three" by the Government of Western Australia Department of Parks and Wildlife[4] meaning that it is poorly known and known from only a few locations but is not under imminent threat.
