Coryphantha pseudonickelsiae

Structure and identification

Stems are spherical, solitary or offsetting, with fibrous roots and a green epidermis. Conical tubercles become more pyramidal over time. Pale lateral spines spread radially and partly interweave. The dark central spine, when present, projects distinctly and curves downwards. The monograph notes its late and uneven appearance. Flowers are small and yellow. [Dicht and Lüthy 2005, p. 158]

Habitat and variation

The monograph documents sites in northeastern Durango on hills and slopes with lava gravel. The older name C. indensis was associated with some of these populations. The later morphological analysis emphasises the distinction of the group from hooked forms of C. delicata and C. hintoniorum.
