C. olivana Ritt. (Kakt.Sudamer.1980). Plant no. 12, map 4.

Backeberg indicated the plant is larger than C. mollicula, and presumably similar also. The Chileans (Vol. 9, no.32) discusses the large flowers of both species, but C. olivana comes from 1º further north than C. mollicula. Taylor (1981) suggested that this may be a form of C. hypogaea.

C. paposoensis Ritt. (Kakt. Sudamer. 1980).

Habitat-20 km north of Paposo.

This is an invalid designation according to Taylor (1981).

C. pendulina Ritt. (1959)
Plant no.73, map 7. KK 1391, FR 504.

Body-globular later cylindrical, to 2 m long. Clumping, single heads to 14 cm across, dark green, with 12-19 bluntish ribs, thickened near areoles. Crown brownish-grey, spiny; Areoles-light grey-brown; Spines-at first brown-black to black, 6-8 radials. 1.5-2.5 cm long, straight to a little curved. 1 central (some­times 2) stronger, to 4 cm long; Flower-3.5 cm long, 3.5-4.0 cm across, at first scented; Fruit-round 1 cm across, light green, brownish above with shiny black seeds; Roots -turnip-like; Habitat-Frai Jorge (coast).

Note: Taylor (1981) suggests that C. pseudocoquimbana and its varieties to be in themselves only varieties of c. pendulina.  

C. pepiniana Lem. (ex Salm Dyck) Backeb. Plant no. 58A, map 6. KK 1162, KK 618.

Body-.solitary, elongated, to 20 cm high, 10 cm across. Dull grey-green at first lighter, 12 ribs with deep verticle furrows. Crown yellowish-white, spiny; Areoles­moderately large with yellow to white felt, very profuse at top; Spines ­yellowish-brown later grey, slightly curved. 7 subulate radials 2 cm long, 1 central larger and stronger; Flower-yellow, 2.5 cm long; Habitat-Chile!

Note: Echinocactus pepinianus Lemaire was named without flower or fruit. Britton and Rose thought it might be in their genus Neoporteria although they did add that if it did come from Chile or Peru as Schumann suggested, it might be a Copiapoa (Neoporterias also come from Chile). However, Backeberg treats it as a Copiapoa. I feel it is another doubtful species because of the lack of a full description.

Knize found KK 1162 near Algarrobo at 600 m, and KK 618 near Maitencillo at 600 m. However in the maps I sent to him, he did not confirm the actual area of collection. Both place names are on the map in the vicinity of C. vallenarensis. See comment on C. fiedleriana.  

C. pseudocoquimbana Ritt. (Taxon 1963) Plant no.65, map 7. FR 1086, KK 86, KK 10A, KK 14A, KK 14B, KK 14.

Body-clumping, 20-30 cm high, 5-10 cm across, green with 10-18 ribs, 8-15 mm wide with humps. Crown with grey wool; Areoles-3-10 mm across and apart, round, raised, grey; Spines-pale brown soon becoming grey. 8-12 radials, acicular, mostly erect 1-2 cm long. 3-7 centrals, thick, mostly erect 2 to 4.5 cm long; Flower-2.75 to 4.5 cm long with pale sulphur yellow, spathu­late petals. Pale green ovary and funnel shape to flattened tube with red brown scales. Stamens 5-12 mm long, pale saffron, anthers saffron white to gold. Style 16-22 mm long, pale saffron, stigma with 9-17 lobes; Fruit-more or less globular, 1 cm across. Base pale green, top red-brown. Seeds 1.75 mm long, 1.15 mm wide, rich green, (from latin diagnosis), covered with very small tubercles. Hilum large; Roots-strong, long, thick, narrower at top; Habitat-north of Choros bajos.

C. pseudocoquimbana v. vulgata

Plant no.69, map 7. FR 230, KK 10, KK 1390. This differs from the species by having larger areoles, fewer radial and central spines and smaller flowers. Habitat-on the coast near Coquimbo.

C. pseudocoquimbana v. domeykoensis

No details available.

Note: Taylor (1981) suggests these are all varieties of C. pendulina.
