Leaves light green or gray green, densely appressed, scalelike, dimorphic, 1-1.5 mm long, apex sharply pointed; facial pairs with a linear abaxial gland; lateral pairs folded face-to-face, overlapping basal part of facial pairs, ridged abaxially. Juvenile foliage, often long-retained in cultivation , soft blue-green leaves 4-7 mm long in whorls of 2 or 4. Pollen cones ellipsoid or ovoid, 2.5-5 mm; microsporophylls 10-14.
