In flower, Unigenes humifusa presents a colourful sight on the ground. The stalked flowers grow solitary and spaced from stem nodes in a raceme, subtended by small, leaf-like bracts. The green stems are angular.
The lower corolla lips spread, the upper ones are about erect. The narrowly cone-shaped ovaries are tipped with small, narrow and spreading sepal lobes (Bean and Johns, 2005; Bond and Goldblatt, 1984; iNaturalist).
