Cact. Gen. Sp. Nov., 3. 1839
sw United States, Mexico.
Species 4–5 (1 in the flora).
Astrophytum is most often recognized as a distinct genus. Chloroplast DNA evidence (C. A. Butterworth et al. 2002), however, confirms that it is among the closest relatives of Echinocactus. Unlike Echinocactus, the stem surfaces of Astrophytum species are speckled by numerous tiny white tufts of minute, matted hairs in addition to the regularly spaced woolly areoles.
