The edges of the lobes are rolled under, concealing the lower surface apart from the midvein.

The flowers are arranged in erect, cylindrical clusters on a rachis mostly 80–120 mm (3.1–4.7 in) long.

Flowering occurs from March to October and the fruit is a woolly-hairy follicle 14–18 mm (0.55–0.71 in) long.

[2][3] Grevillea whiteana was first formally described in 1986 by Donald McGillivray in his book New Names in Grevillea (Proteaceae) from specimens collected from Glenwood Station, 48.3 km (30.0 mi) south-west of Mundubbera in 1974.

[3] Mundubbera grevillea grows in forest and on rocky slopes in sandy soil from Boondooma northward to Mundubbera and on Mt Walsh near Biggenden in south-eastern Queensland.
