It is a compact, many-branched shrub with flattened cladodes, leaves reduced to scales, and yellow to pinkish-red pea-like flowers.

[2][3] Bossiaea celata was first formally described in 2006 by James Henderson Ross in the journal Muelleria from specimens collected in Boorabbin National Park in 1998.

[3][4] The specific epithet (celata) means "concealed", referring to the difficulty of locating specimens of this species.

[3] This bossiaea grows in deep sand in open mallee in the Coolgardie biogeographic region of Western Australia.

[2][3] Bossiaea celata is classified as "Priority Three" by the Government of Western Australia Department of Parks and Wildlife[2] meaning that it is poorly known and known from only a few locations but is not under imminent threat.
