. It is threatened by a number of human activities and its small population sizes make it vulnerable. It is a federally listed threatened species.

This is a perennial herb growing up to 40 centimeters tall with one or more upright, square-edged stems. The tiny, narrow leaves are linear in shape with rolled edges and are just a few millimeters long. Flowers occur next to the leaves. The corolla has one lower lip and a hoodlike upper lip.

. In protected areas that are managed appropriately with prescribed burns the plant is locally abundant and flowers properly. In areas where fire suppression is practiced, large and woody vegetation grows up and produces shade so that the plant does not receive enough sunlight. The plant itself responds to fire. It simply does not produce flowers if it does not burn every three years. Lack of fire is a main threat to the species.

Other threats include habitat destruction during coastal development and the conversion of land to agriculture, particularly silviculture
