- Morphological features. Sterile shoots covered with homophyllous leaves, ranging from 19 to 95 mm long and from 3 to19 mm wide (average of 6 mm), concentrated mainly at the apex. Leaves spiraled, with divergence angles acute, bifacial, falcate and slightly imbricated, ranging from 7 to 54 mm long and 0.5 to 2 mm wide, with apexes acute, bases decurrent, margins entire; midvein well defined, with long, thick hairs; second order veins parallel to midvein. Paradermal view. Adaxial epidermis constituted by elongated polyhedral and angular cells with 4-5 sides, measuring 63 mm long and 20 mm wide. Periclinal walls with papillae and pores. Stomata sunken, monocyclic, and arranged in bands. Subsidiary cells papillate, in number of 4-6, larger than the rest of the epidermal cells. Abaxial epidermis constituted by isodiametric and polyhedral cells (32 mm long and 25 mm wide) of 4-6 sides. Anticlinal walls thin and slightly wavy. Periclinal walls with papillae and pores. No stomata observed.
