high, planar, arising from root-like stolons, firmly attached to substrate. Stems erect, branched or unbranched, giving rise to side branches in a regularly pinnate manner. Both main stem and branches polysiphonic, thinning out to monosiphonic at distal end; divided into long, roughly equal internodes; nodes, though indistinct, transverse to slightly oblique; an incision of perisarc at distal end of internode, on side next to adcauline base of primary hydrophore. Side branches originating directly under a primary hydrotheca and placed on small apophysis, forming annulus at junction of the two. Abcauline wall of primary hydrophore at place of fusion with basal part of side branch having characteristic, comma-shaped, internal projection of perisarc (fig. 2E). Side branches alternate, straight to slightly flexuose, evenly spaced, and at a constant angle of

45° to main stem; some secondary branches occur. Primary hydrophore prominent, surpassing distal node of segment and not delimited by basal constriction; pseudodiaphragm always present, at least below primary hydrotheca. Hydrothecae alternate; short, asymmetric, with abcauline side nearly straight and adcauline side flared. Rim even, very slightly everted; wall of hydrotheca with row of desmocytes; renovations often present (up to 6). Length of additional secondary hydrophores varied, longer than diameter; basally with undulated perisarc, elsewhere smooth. Hydranths with 16–20 filiform tentacles.
