Dicrastylis thomasiae S.Moore Mallophora corymbosa Endl.

[3] Dicrastylis corymbosa is a many branched shrub, growing to 30 cm high, in yellow and brown sands.

Its stems are roughly circular in cross section, and having no peltate scales.

The calyx has five lobes (1.3–2 mm long), and is covered in dendritic hairs, and the white to cream corolla is 3.8-4.5 mm long, with no dots or stripes in its throat.

[4] It was first described by Stephan Endlicher in 1838 as Mallophora corymbosa,[1][5] but was assigned to the genus, Dicrastylis by Ahmad Abid Munir in 1978 to give Dicrastylis corymbosa.
