Stems: Stems 1-several, smooth; basal offshoots prostrate to trailing and forming overwintering rosettes.
Leaves: Basal leaves linear to oblong, to 1/3 in. long; stem leaves alternate, linear, to 1 1/4 in. long, smooth.
Inforescence:
Flowers: Flowers in a narrow raceme; blue to purple; about 1/2 in. long; bilaterally symmetric; tubular, with a slender spur and opening to 2 lips, the upper lip 2-lobed and the larger lower lip 3-lobed; the white throat has 2 ridges.
