Individual leaves may be up to 2 cm long and have entire margins with 1-3 veins from the base of the blade.The yellow flowers are small (from 4-8 mm long) with small red dots on the lower lip. The flower is slightly two-lipped, with a notch at each petal tip. The sepals are fused, up to 5 mm long, and a deep cinnamon color.
