[1] The annual herb has a tufted habit and typically grows to a height of 2 to 20 centimetres (0.8 to 7.9 in).

The shiny, glabrous, thin, pointed leaves are typically 6 centimetres (2.4 in) in length with a width of 1.6 millimetres (0.06 in).

[1] The flower heads have a flattened oblong-ovoid shape and are around 3 mm (0.12 in) wide.
