Bossiaea buxifolia is a prostrate to weakly erect shrub that typically grows to a height of up to 50 cm (20 in) tall, although sometimes as high as 1.3 m (4 ft 3 in) and has softly-hairy stems.

Flowering occurs from spring to early summer and the fruit is a narrow oblong pod 15–30 mm (0.59–1.18 in) long.

[2][3][4][5] Bossiaea buxifolia was first formally described in 1825 by Allan Cunningham who found it growing "upon rocky, brushy hills" and published the description in the chapter "On the Botany of the Blue Mountains" of Barron Field's book, Geographical Memoirs on New South Wales.

[8] Matted bossiaea grows in forest and woodland occurs south from Kroombit Tops National Park in south-eastern Queensland, along the coast and tablelands of eastern New South Wales and the Australian Capital Territory to the ranges east of Omeo in eastern Victoria.
