, and is confirmed by the recent observations. This species is recognizable by the combination of ribbon-like root, pollen in dyads, a single stamen, leaves arranged all around the stem (not distichous), that are linear, entire to 3-4 times forked. When a developed stem is present, the leaves at base are usually shorter, sometimes damaged, which can give the impression of stem-scales. Nevertheless, there is a continuum in length and shape between basal and apical leaves, which suggests no true stem-scales (as typical for
