Daviesia glossosema, commonly known as maroon-flowered daviesia, is a species of flowering plant in the family Fabaceae and is endemic to a restricted area of south-western Western Australia. It is an erect shrub with tangled, spreading branches, cylindrical, sharply-pointed phyllodes, and unusually-shaped maroon flowers.

Description
Daviesia glossosema is an erect shrub that typically grows to a height of  and has spreading, tangled branches with glaucous foliage. Its leaves are reduced to scattered, erect, needle-shaped, sharply-pointed phyllodes  long and about  wide. The flowers are arranged in racemes of two to five on a peduncle  long, the rachis  long, each flower on a pedicel  long with bracts about  long at the base. The sepals are about  long and joined at the base with minute teeth. The petals are maroon, the standard egg-shaped,  long and curved backwards, the wings about  long and curved inwards exposing the keel and stamens, and the keel is about  long. Flowering occurs from September to November and the fruit is an inflated triangular pod  long.

Taxonomy and naming
Daviesia glossosema was first formally described in 1995 by Michael Crisp in Australian Systematic Botany. The specific epithet (glossosema) is derived from words meaning "tongue" and "standard", referring to the unusual shape of that petal.

Distribution and habitat
Maroon-flowered daviesia grows in heath in a small area of the Stirling Range in the south-west of Western Australia.

Conservation status
Daviesia glossosema is listed as "Threatened Flora (Declared Rare Flora — Extant)" by the Department of Biodiversity, Conservation and Attractions and an Interim Recovery Plan has been prepared.
