[2][3] The flowers are scattered, appearing in a few upper leaf axils on erect or spreading stalks 2–3 mm (0.08–0.1 in) long, and apart from the styles are almost hidden by the foliage.

[2][3] Verticordia crebra was first formally described by Alex George in 1991 from specimens collected in the Fitzgerald River National Park and the description was published in Nuytsia.

[1][4] The specific epithet (crebra) is derived from the Latin word creber meaning "close", "pressed together" or "frequent",[5] referring to the crowded leaves.

[6] Verticordia crebra is classified as "Threatened Flora (Declared Rare Flora — Extant)" by the Western Australian Government Department of Parks and Wildlife[6] and has been listed as "Vulnerable" (VU) under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act).

[3] While probably not an attractive garden plant, research is being done to determine the best methods of propagation and cultivation so that the species may be conserved in the event of loss of wild populations.
