- Diagnosis
- Stems >6 mm long, 75 μm wide; slightly flexuose, unbranched, terete, rather densely foliate; leaves ca. 15 per 1 mm, multistichous; foliage more dense distally, while in proximal part leaves are smaller and relatively more remote, so stem is seen among leaves. Leaves erect, 0.3-0.5 mm long, ca. 0.1 mm wide, broadly lanceolate, gradually and broadly acuminate or narrowly acute, channeled-concave; margin serrulate; long single costa absent. Smaller leaves in proximal part of shoot appressed, 0.20×0.08 mm. Laminal cells in mid-leaf elongate-linear, 7-8 μm wide, 35-40 μm long, in upper leaves shorter and closer to leaf corners short, to 3:1.
