C. exilis is an annual herb producing a slender, erect stem often exceeding half a meter in height. The bright green leaves are lance-shaped to narrowly oval, and hairless. The top of the stem is occupied by the inflorescence, with open flowers and deflexed buds towards the tip of the stem. Each of the four petals has a narrow claw and diamond-shaped limb. The entire petal is up to 1. 5 centimeters long and white or soft purple or pink, sometimes with a purple spot. The fruit is a capsule up to 3 centimeters long and about 2 millimeters wide that may contain from a few to 80 seeds. Description from Calscape
