Short description বহিঃ অঙ্গ সংস্থান

Stems up to 12 cm high, polysiphonic over part of their length. Branching alternate and in one plane; sometimes anastomoses amongst the branches. Hydrothecae arranged in decussate verticils of two to four hydrothecae, forming four to eight longitudinal rows. Frequently, however, hydrothecal verticils with irregularities, and indistinct. Hydrothecae low, sunken into branches for approximately one-third of their volume. Adcauline hydrothecal wall adnate to internode for almost its entire length. Hydrothecal abcauline wall straight or slightly concave; hydrothecal aperture slightly laterally depressed; rim uneven due to the presence of an elevation of the abcauline hydrothecal wall, aperture only slightly tilted downward. Hydrotheca without mushroom-shaped diaphragm. Male and female gonothecae present. Female gonotheca arising from a stolonal process (modified branch) originating at the hydrothecal base. This process provided with alternately arranged, isolated hydrothecae with one gonotheca at the base of each hydrotheca. Female gonotheca pear-shaped, sometimes provided with a few spine-shaped projections. Gonothecal aperture not observed. Male gonothecae inserted directly at the hydrothecal base and arranged in close proximity on the branches; gonotheca fusiform with a small circular aperture at the distal end.
