Identification

This is a 4 to 20 tall, perennial forb that rises on one or more stems from fibrous roots.

The stems can be drooping, almost laying flat on the ground, to almost erect. They are unbranched, 4-angled, and winged.

The leaves are opposite, egg-shaped to oblong egg-shaped, to 2 long, and ¼ to 1 wide. The middle stem leaves are ½ as wide as long. They are on ¼ to 1 long leaf stalks. The upper surface is almost hairless or is covered with very small, coarse, stiff hairs. The lower surface is almost hairless. The margins are wavy.

The inflorescence is an egg-shaped, ¾ to 2 long, and to ¾ wide spike of many flowers at the end of the stem.

The flowers are to ¾ long. There are 5 petals fused at the base into a tube about long, then separated into an upper and lower lip. The upper lip is purple, almost round, hood-like, about 3 16 in diameter, and notched at the tip. The lower lip is white and about half as long as the upper lip. It is divided into 3 lobes, a large central lobe and 2 smaller lateral lobes. The lateral lobes are about 1 16 long and spreading. The central lobe is about long, strongly bent downward, and fringed at the tip. There are 4 stamens that are concealed under the hood.

The fruit is a smooth brownish-yellow nutlet about 1 16 long.
