Hibbertia lepidocalyx is a species of flowering plant in the family Dilleniaceae and is endemic to Western Australia. It is a shrub with thick, linear, cylindrical leaves and yellow flowers with nine or ten stamens in a single group on one side of the two carpels. Description. "Hibbertia lepidocalyx" is a shrub that typically grows to a height of up to and has glabrous branchlets, at least when they are mature. The leaves are spirally arranged, sometimes crowded, thick, linear and cylindrical, long and wide on a petiole long. The flowers are arranged singly in leaf axils on  a peduncle long with bracts up to long. The flowers are in diameter with five sepals joined at the base, long but varying in length.

There are nine or ten stamens fused at the base, on one side of the two scaly carpels that each contain three to six ovules. Taxonomy. "Hibbertia lepidocalyx" was first formally described in 2002 Judith R. Wheeler in the journal "Nuytsia" from specimens collected near Lake King in 1968. The specific epithet  ("lepidocalyx") means "scaly sepals". In the same journal, Wheeler described two subspecies and the names are accepted by the Australian Plant Census: The subspecies epithet "tuberculata" mean refers to the wart-like lumps on the upper leaf surface. Distribution and habitat. Subspecies "lepidocalyx" grows in mallee and shrubland in the Mallee biogeographic region, and subspecies "tuberculata" is found in woodland and heath but is only known from two populations in the Coolgardie bioregion. Conservation status. "Hibbertia lepidocalyx" and subspecies "lepidocalyx" are classified as "not threatened" but susp. "tuberculata" is classified as "Priority Three" by the Government of Western Australia Department  of Parks and Wildlife meaning that it is poorly known and known from only a few locations but is not under imminent threat.
