Hovea parvicalyx is a species of flowering plant in the family Fabaceae and is endemic to Queensland, Australia. It is a shrub covered with white to grey, coiled hairs, very narrowly elliptic to narrowly elliptic or strap-shaped leaves, mauve flowers and a sessile, densely hairy pod.
Hovea parvicalyx is a shrub that typically grows to a height of up to and is covered with white to grey, coiled hairs. The leaves are very narrowly elliptic to narrowly elliptic, lance-shaped with the narrower end towards the base or strap-shaped, long and wide on a petiole long. There are stipules long at the base of the petioles. The flowers are mostly borne in groups of two or three on a peduncle long, each flower on a pedicel long, with egg-shaped bracts and bracteoles long at the base. The sepals are long and joined at the base, forming a tube long, the upper lip about wide. The petals are mauve, the standard petal long with a central white "flare", the wings wide. Flowering occurs from June to August and the pods are sessile and densely hairy, the seed with an aril long.
Hovea parvicalyx was first formally described in 2001 by Ian R. Thompson in Australian Systematic Botany from specimens collected north-west of the Jeannie River in 1984.
This species of pea grows in sand, on sandstone outcrops or in gravelly soils, in forest and woodland in far northern and eastern Queensland from near the Starcke National Park to the Roma district.
Hovea parvicalyx is listed as of "least concern" under the Queensland Government Nature Conservation Act 1992.
