Gorelick R., Immature Epithelantha micromeris resemble Epithelantha bokei, Haseltonia, 2026, 33(1):1-7, doi: 10.2985/026.033.0104
Observations of Epithelantha micromeris near Anthony Gap in Texas describe changes in spine covering and apex shape as the stem matures. The article compares small pale stems with the appearance of E. bokei, proposes a paedomorphosis hypothesis and presents the underground parts of specimens and circumferential constrictions of older stems.
