J. holoschoenus could be confused only with J. prismatocarpus and J. fockei; it differs from the former in having 6 (not 3) stamens, and leaves with transverse septa only; from the latter in the longer capsule ± = tepals and only slightly tapered towards the top. Stems of J. holoschoenus usually lack transverse septa in the upper part, but occasionally have minute, barely discernible ones.
