Discussion

Lygodesmia texana is easily distinguished by its laciniate-lobed basal leaves that form rosettes in younger stages, relatively large involucres and florets, phyllaries with an apical appendage, and smooth cypselae. It is closely related to L. aphylla, which has a more eastern distribution, lacks laciniate leaves in rosettes, and has sulcate cypselae. Lygodesmia texana apparently hybridizes with L. ramossisima in trans-Pecos Texas, and the two species can be difficult to distinguish (A. S. Tomb 1980).
