Discussion
Plants with capsules distinctly longer than the perianth have been referred to as Juncus drummondii var. subtriflorus. Those plants frequently occur sympatrically with J. drummondii (strict sense) through most of its range, leaving considerable doubt as to the value of recognizing such variation.
