The inflorescence consists of 1–14 white or pale pink flowers and appear in axillary racemes. The flower stem is 0.5–3 mm (0.020–0.12 in) long with flattened white hairs.

Taxonomy and naming
Hakea cycloptera was named by botanist Robert Brown in 1810 and published in Transactions of the Linnean Society of London.[6] The specific epithet (cycloptera) is derived from the Ancient Greek words kyklos meaning "circle"[7]: 248 and pteron for "wing",[7]: 859 referring to the shape of the seed wing.[2]
Distribution and habitat
Confined to the Eyre Peninsula in South Australia. Grows in sandy soil in mallee scrub and withstands moderate frosts. A useful, dense shrub for dry conditions and wildlife habitat.[3]
