Discussion
F. Chiang Cabrera (1981) noted that Lycium texanum is similar to L. andersonii, differing mainly in the type of pubescence (short, straight hairs versus longer, curved hairs). Data from at least one nuclear gene region suggest a close relationship with L. andersonii (R. A. Levin et al. 2009), and it is possible that L. texanum is simply the Texas variant of L. andersonii.
