Echinocactus bridgesii Pfeiffer, Abbild. Beschr. Cact. 2: pl. 14. 1847.

Echinocactus bolivianus Pfeiffer, Abbild. Beschr. Cact. 2: under pl. 14. 1847.

? Echinocactus salm-dyckianus Pfeiffer, Abbild. Beschr. Cact. 2: under pl. 14. 1847.

Simple, globose, very woolly at apex; ribs 8 to 13, straight, rounded, green; radial spines 5 to 7, stout, straight or somewhat curved; central spine solitary, porrect, 3 cm. long; flowers pale yellow; outer perianth-segments narrowly ovate, acute, reddish; inner perianth-segments broadly oblong, obtuse; scales of ovary and flower-tube described by Schumann as woolly in their axils, but undoubtedly he is wrong.

Type locality: Not cited.

Distribution: Reported from Bolivia, but perhaps from that part of Bolivia now belonging to Chile.

This name occurs first in Cels's Catalogue of 1845, but without description. We know the plant only from descriptions and illustrations; it may not belong to this genus.

Echinocactus macracanthus Salm-Dyck (Cact. Hort. Dyck. 1849. 143. 1850) may belong here. The varieties Echinocactus macracanthus cinerascens Salm-Dyck and E. pepinianus affinis Monville were both referred by Labouret (Monogr. Cact. 177. 1853) as synonyms of Echi-nocactus macracanthus Salm-Dyck.

Illustrations: Pfeiffer, Abbild. Beschr. Cact. 2: pl. 29, as Echinocactus echinoides; Pfeiffer, Abbild. Beschr. Cact. 2: pl. 14, as Echinocactus bridgesii.

Figure 100 is copied from the first illustration above cited.
