Type locality: Yura, near Arequipa, Peru. Distribution: In the mountains of southern Peru, altitude 2,000 to 3,300 meters. This species is one of the three or four common cacti found on the hills and in the valleysboth above and below Arequipa, and, while not the largest, is often the most abundant andconspicuous. Dr. Rose studied this plant in Peru in 1914, collecting living and herbariumspecimens, including the very long spines described above (Nos. 18780, 18965). Figure 99 is from a photograph taken near Arequipa, Peru, by T. A. Corry in 1917;figure 101 represents a flower collected by Dr. Rose near the same place in B -: II ?
