Leaves dimorphic, yellowish green; upper leaves in 2 alternating rows flattened into 1 plane, firm to rigid, decurrent, ovate to lanceolate, often falcate, 3–5 mm long, 1–1.5 mm wide; leaves of undersurface in 2 rows, much smaller and scale-like, with translucent membranous obtuse usually dilated tips. Strobili erect, terminal, 1–3 cm long, solitary. Sporophylls imbricate, subpeltate, ovate-sagittate, stramineous, with translucent membranous tips.
