Taxonomy

This species has been confused with other species or forms with gramineous fronds (see under S. ceratophylla, S. enervis, S. lateritia, S. setacea). All of these can be distinguished by the wider lamina, which is flat or slightly incurved in cross section. True S. bisulcata has an almost quadrangular cross section of the lamina, and a rhizome with the fronds distinctly spaced.
