|discussion=<p>Lygodesmia aphylla is recognized by its erect, sparingly branched habit, leafless stems, relatively large involucres and florets, apical appendages on phyllaries, and grooved cypselae. The habit is similar to that of L. texana. The basal leaves are frequently absent at flowering and are entire, not pinnately lobed as in L. texana.</p>
