Habenaria repens is remarkable in sometimes being truly aquatic. Often forming floating mats, the plants then are commonly decumbent, at least basally, and new shoots and slender roots arise abundantly from much of the length of the stem. A few spheroid tuberoids are sometimes produced from roots arising at wide intervals. Other roots bear new shoots some decimeters from the parent stem; the distal portion of the root then commonly enlarges into a slenderly lance-fusiform tuberoid.
