The bracts are lance-shaped and lack teeth.The corolla is white, although it may be tinted in mauve with pink or purple veins. The entrance to the tube is yellow and has a biconvex shape. The conical spur is up to 4 mm (0.16 in) long. The fruit is an oblong capsule that narrows very slightly towards the tip. The base and upper margin are rounded. It has no horns.
