Discussion
The only known North American population of Pleopeltis polylepis occurs in the Davis Mountains of western Texas. It is placed in variety erythrolepis, which differs from var. polylepis, the variety common in Mexico, in that the scales on the abaxial surface of mature blades are fringed-ciliate rather than entire to erose, and mostly ovate-lanceolate rather than spheric. In addition, the scales of the abaxial blade surface tend to be more abundant than in var. polylepis. The two varieties are very similar, however, and a broad region of overlap exists in parts of Mexico where plants of intermediate morphology occur (T. Wendt 1980). In general, var. erythrolepis occurs in northern Mexico and Texas, and var. polylepis ranges from southern Mexico to Guatemala.
