It is erect or pendulous, slender, 50 cm (20 in) long, 13 to 16 mm (0.51 to 0.63 in) wide, usually unbranched stems with internodes of 3 to 4 cm (1.2 to 1.6 in) in length. It bears distichously arranged, terete leaves. They are 13 to 16 cm (5.1 to 6.3 in) long and 3 to 4 mm wide and fleshy. Stomata are presented on the entire leaf surface.
