Etymology
The name, Haemodorum, was chosen by Smith in 1798 for the blood-red root, haem- being Greek for blood-red. Mueller in 1858, gave this species the specific epithet, brevicaule, which derives from the Latin brevi- (short), and caulis (stem), giving the meaning 'short-stemmed'.

The perianth is formed of two rings of three tepals which are uniformly red, red-brown, purple or black. It has three stamens all at the same level with the filaments being 1 to 1.2 mm long and having slightly longer anthers. The plant flowers from September to December.

Taxonomy
H. brevicaule was first described by Ferdinand von Mueller in 1858. This description was slightly modified in 1987 by Macfarlane. The syntype is held in the National Herbarium of Victoria and was collected by Mueller in 1855 towards the Macadam range in the Victoria-Daly region of the Northern Territory.
