 The somewhat scented, nodding flowers grow individually from the leaf axils on long flower stalks (or pedicels) so the flowers are above the leaves, with two small bracts almost opposite each other in the upper part of the stalk.The five sepals are narrowly oval in shape with a pointed tip and are long.The five petals are purple or violet, veined, with the four upper ones oblong and long, the lower one shorter and connected to a long, tube-shaped, blunt spur.
