Type locality: Rocky sandy bottoms near Mollendo, southern Peru. Distribution: Foothills of southern Peru, altitude 600 meters. This plant is very abundant in the foothills of southern Peru. In many places it isthe only conspicuous plant in this arid region, which in the dry season is otherwise almostdevoid of plant life. In the shelter of these plants thousands of lizards live and, doubtless,feed upon the flowers. Dr. Rose collected the species in 1914 (No. 18810) at Posco, Peru,not far from the type Fig. ioi.—Flower of C. brevistylus. Fig. 102.—Flower of Fig. 103.—Fruit of Corryocactusbrachypetalus. Figure 102 represents a flower and figure 103 a fruit, collected by Dr. Rose at Posco,Peru, in 1914; figure 100 is from a photograph taken near Posco, Peru, by T. A. Corry Corryocactus melanotrichus (Schumann). Cereus melanotrichus Schumann, Gesamtb.
