The main branches appear flat to slightly wrinkled, with compressed structures and sharp edges.The primary lateral branches are arranged alternately and have a shape ranging from linear-lanceolate to elongated and ovate. Their edges exhibit undulating patterns to deep dentations, and the tips are blunt. The base of these branches is somewhat symmetrical. Secondary branches have a smooth texture, and their secondary lateral branches are also arranged alternately, with shapes ranging from oblanceolate to ovate. Their margins may be serrated or dentate, and the tips are either blunt or pointed, while the base is wedge-shaped and somewhat symmetrical. Cryptostomata are notably prominent in this structure.
