Babingtonia triandra is a low, spreading to almost prostrate shrub that typically grows to a height of 15–50 cm (5.9–19.7 in), the leaves clustered on short side-shoots.

The flowers are arranged in groups, sometimes up to 16 in leaf axils on a peduncle 1.5–4 mm (0.059–0.157 in) long with bracts 0.7–1.5 mm (0.028–0.059 in) long but that fall off as the flowers open, and smaller bracteoles.

[2][3] Babingtonia triandra was first formally described in 2015 by Barbara Rye and Malcolm Trudgen in the journal Nuytsia from specimens collected in the Calingiri area in 2003.

[3] This species grows in Melaleuca thickets in a winter-wet depression near Calingiri in the Jarrah Forest bioregion of south-western Western Australia.

[2][3] Babingtonia triandra is listed as "Priority Two" by the Western Australian Government Department of Biodiversity, Conservation and Attractions,[2] meaning that it is poorly known and from only one or a few locations.
