Discussion

Phyllanthus ericoides is known from only a few populations in Brewster and Terrell counties, Texas, and nearby Chihuahua and Coahuila, Mexico. Although stunted plants of the related P. polygonoides may resemble P. ericoides, the latter may be distinguished by its woody habit, pungent leaves, shorter pedicels, completely connate filaments, and smaller seeds. In addition, the woody base of P. ericoides is reported to smell like coffee with chicory (M. C. Johnston and B. H. Warnock 1963).
