The flowers of Brachycorythis conica subsp. transvaalensis grow in a dense, cylindrical raceme. In flower the plant reaches heights around 30 cm. The sepals are broad, tapering to pointed tips, the dorsal one positioned over the flower like a hood.
The lateral petals are similar to the sepals, but broad-tipped, positioned just below the gaps between the lateral sepals and the hood. These petals curve in slightly over the column. The sepals and lateral petals are white with a faint pinkish tint.
The broad, partly deflexed lip is covered in scattered, pinkish purple spots. It has a broad, shallowly three-lobed tip and an irregularly toothed margin. Flowering happens from midsummer to mid-autumn (iSpot; wildorchids.co.za).
