Jamesbrittenia lesutica is a branched perennial herb with opposite, small, pale green leaves. The leaf shape is ovate with deep lobes or teeth along the margins. The leaves and stems are finely hairy.
Flowers grow near stem tips in axillary racemes. The calyx of the flower is small, green and hairy with pointed lobes that spread or recurve at their tips. The long, cylindrical corolla tube is hairy and brownish purple in colour. It has an upward bend or kink near the flower mouth. The five more or less rectangular petal lobes are notched at their tips, slightly undulating along their softly textured pink surfaces. The narrow flower mouths give green, orange, white or finely lined glimpses at and into the tubes of the different flowers in the photo. This picture was taken in the east of Lesotho in January.
It is not known how far beyond the high elevation grassland of the Maluti and Drakensberg Mountains the plant is distributed (iSpot).
