produces one or several stems, slender but tall and erect, that branch towards the top. They bear long, thin, linear leaves at alternate intervals. Lower leaves may be narrowly lanceolate - slightly wider towards the base. Leaf margins may be partly folded up along the axis, and while usually entire, they occasionally have a few small, well-separated teeth.
Flowers are composed of four purplish sepals, and four larger pink ot purple petals, which are narrow at the attachment point (the claw), and much wider above. Darker purple veins run through the petals, branching from the base. The flower center contains a group of anthers, projecting out just a short distance. This species generally blooms quite late in the season, extended by rainfall well into the fall.
