There is no rhizome, the roots fibrous and quite short. The sheets are linear to lanceolate, 8 to 10 millimeters long and 2 to 3.3 millimeters wide. They stand as a down-to-earth rosette and close to the stem, where they are around 4 millimeters long and 2.5 millimeters wide.
The inflorescence is a double wrap consisting of two to six flowers . The almost sessile flowers are 8 to 9 millimeters long and blue to bluish purple with yellow, 4.5 to 5.5 millimeter long lobes. The flower tube is cylindrical to three-angled and 3.5 to 5.5 millimeters long, the 0.5 to 0.8 millimeter long wings are very narrow and run from below the ovary to the middle of the outer flower lobe. The outer lobes are thin, upright, slightly bent back and around 1.4 millimeters long, the inner ones are thin, upright, lanceolate with a blunt tip and 0.7 millimeters long. The stamens are sessile and start in the pharynx, the connective has two short, lateral arms that carry the thecae . The stylus is thickened, thread-like and, including the stigmas, of the same length as the flower tube, at its end are the three almost sessile, trumpet-shaped stigmas .
The ovaries are elliptical to inverted egg-shaped and 3.5 to 4.5 millimeters long. The inverted egg-shaped capsule opens along irregular transverse slits. The seeds are elliptical and yellow.
