The stems are thin, cylindrical, and filiform, measuring approximately 0.5 mm in width. Several branches originate together from the short basal primary axis. The leaves have petioles and are either linear or linear lanceolate in shape, with a narrow or rounded tip. They are thin and membranaceous, and their bases are wedge-shaped and somewhat translucent. The leaf margins have serrated teeth, and there is a midrib present, with small cryptostomatas scattered on both sides of the leaves. Occasionally, a single sharp tooth is located at the base of the leaf. The vesicles are nearly spherical in shape.
