|

Colony bushy, composed of a bunch of stems, up to 2.8 cm high, arising from creeping stolon. Basal part of stems of varied length, provided with a number of twists above origin from stolon; remainder divided into regular internodes by means of oblique nodes sloping in alternate directions. Internodes relatively short, decidedly geniculate, with smooth, rather thin perisarc, each bearing distally a hydrotheca. Branching subdichotomous, starting among the proximal most internodes, thus making the main stems indistinct; side branches originate from below the bases of stem hydrothecae, either laterally or decidedly shifted to one side of the stem; 1-6 hydrothecae between successive side branches; occasionally, aberrant side branches are given off from within some basal stem hydrothecae; up to 5th or 6th order branching observed; tips of branchlets from various planes often form tendrils, creating anastomoses with neighboring branches; structure of branches identical to that of stem, except for the first internode that may be longer than the subsequent ones. Hydrothecae biseriate, alternately directed left and right, coplanar or nearly so; adnate for about 2/5th their length to the corresponding internode; flask shaped, slightly swollen basally, more conspicuously on adaxial side; free adcauline wall slightly sigmoid, abcauline wall nearly straight; hydrothecal margin with four unequally developed cusps: abaxial one the longest, adaxial one the shortest and conspicuously flaring, and the two laterals of intermediate length; rim not thickened; two latero-adaxial, internal, submarginal cusps; operculum composed of four triangular flaps with concentric striae. Gonothecae (only female known) arising laterally from below the hydrothecal bases; broadly ovoid, surface provided with 5-7 more or less developed wrinkles; aperture mounted on short distal collar, and surrounded by six rather short spines; embryo development in acrocysts.
