  • Eriosyce napina var. fankhauseri (F.Ritter) Romulski
  • Eriosyce napina var. lembckei Katt.: It has small tubercles, stems that sometimes become elongate, and horn-colored spines.
  • Eriosyce napina var. mitis (Phil.) Donald & G.D.Rowley: it is a dwarf form with a brown body and short spines pressed flat against the stem.
  • Eriosyce napina var. riparia (Mächler & Helmut Walter) Romulski: Distribution: Elqui, east of Trapiche.
  • Eriosyce napina var. tenebrica (F.Ritter) Romulski: has dark greyish brown or greenish-black, spherical to flattened stems 2-4(-7) cm in diameter with a conical taproot. Distribution: valley of the Rio Choros.
