C. longispina Ritt. (Taxon 1963) Plant no.44, map 5.
KK 1135, FR 505.

Body - globose, not strong growing, grey green, sometimes black with 13 - 16 ribs, 1 cm high; Spines - 6 - 10 radials, 1.5 to 5 cm long, 1 - 2 centrals 2.5 to 6 cm long; Flower - 2.5 to 3.5 cm long, with pale saffron petals 1.2 to 1.9 cm long. Tube 8 - 10 mm long with large pointed scales. Ovary globular mostly without scales; Fruit - globose; Habitat - Sierra Homillos, South of Copiapo.

Note: Backeberg considered that the description did not give sufficient difference between either Copiapoa humilis or C. taltalensis to warrant specific status. Ritter thought it had some affinity with C. humilis. Taylor (1981) considers it to be a geographical form of C. humilis.  

C. longistaminea Ritt. (Taxon 1963) Plant no.24, map 4. FR 531, KK 194, KK 1068.

Stamens and stigma about 1.5 cm long; Fruit - pale green; Roots - strong, very short; Habitat - near Esmeralda.

Note: Ritter saw some affinity with C. cinerea, and in 1981, Taylor suggested that this falls within C. cinerea v. cinerea.
