- Plants in loose wefts. Stem more than 4.2 cm long, rather thin, ca. 0.25-0.40 mm wide, straight to more or less geniculate, remotely (6-14 leaves per 5 mm in middle part of stem) and complanately foliate, freely branched, minimal distance between branches 1 mm, branch angle with stem (30-)70-90°, branch foliage similar to that of stems or more dense; in proximal part branches leafless or with smaller leaves. Stem leaves deviating from stem at an angle (55-)80100°, spreading, oblique at insertion, (3.5-) 5-8×1.01.5 mm, oblong-lanceolate, broadly oblong or oblong-ovate, rounded at apex, slightly tapered toward base; margin entire, not bordered, plane except for the base where it is recurved what is seen as dark “border” at lower and upper angles of leaf; laminal cells rectangular, sometimes almost quadrate, (1.5-)2-3(-4):1, 40-85×20-30 μm, in alar region shorter and broader, to 40-45×35-40 μm. Branch leaves to 2.0-0.5 mm long. Juvenille shoots bud-like in leaf axils, 200-250 μm in diameter.
