Tiny stems up to ca 0.5 cm long. Stem internodes long and distinctly arranged in zig-zag fashion. Hydrothecae situated at the end of stem internode. Hydrotheca almost tubular and directed up- and outwards. Hydrotheca free for most of its adcauline wall; free part of adcauline hydrothecal wall straight. Hydrotheca with a distinct inflexion point where adcauline wall becomes free. Abcauline wall straight or slightly abcaudally directed at its distal part. Cusps of hydrothecal aperture sharp and separated by deep embayments. Hydrotheca widening at the aperture.
