Diagnosis

Twigswith helically arranged leaves. Leaves dorsiventrally flattened, lanceolate or linear lanceolate, decurrent and narrowly twisted at base, apex obtuse, margin serrulate, 1.0–2.5cm long and 2–4mm wide. Leaves hypostomatic, epidermal cells mostly rectangular with slightly undulate anticlinal walls. Stomatal band cells polygonal. Stomata anomocytic, rounded, elliptic or elongated-elliptic, mostly parallel or oblique oriented along the leaf axis. Subsidiary cells 5–7.
