The only subspecies of Brachycorythis ovata occurring in South Africa is subsp. ovata. It has white in the centre of its purple lip with one to a few purple spots in the white patch.
The lateral petals are pale, cohering with the flower’s purple hood, the dorsal or median sepal. The concave lateral sepals spread widely. They are pale on their inner surfaces, purple on the outside.
The long, erect bracts that subtend the individual flowers can be seen here, sharply pointing their lance-shaped purple tips upwards (Pooley, 1998).
