|discussion=<p><i>Scorpidium cossonii</i> is often confused with <i>S. revolvens</i> or <i>Hamatocaulis vernicosus</i>. From the latter it is easily distinguished by the hyalodermis and usually present central strand of the stem, differentiated hyaline and inflated alar cells of the stem leaves, and nonplicate stem leaves. <i>Scorpidium cossonii</i> differs from <i>S. revolvens</i> in being dioicous (the latter is autoicous) and in having shorter medial laminal cells with square to shortly fusiform-narrowed ends; the cell ends are short to long fusiform-narrowed in the latter. Both species may have red pigment; in such cases <i>S. cossonii</i> is usually brownish red while <i>S. revolvens</i> is mostly blackish or purplish red. Due to variation in both species, especially when herbarium material is also considered, color should be used with care in identifying specimens. Dark purplish plants usually belong to <i>S. revolvens</i> and predominantly green or yellow-green plants with a brown-red costa and/or leaf base belong to <i>S. cossonii</i>.</p>
