10. Trichocereus peruvianus sp. nov.

Original description:
   Plant 2 to 4 meters high with numerous erect or ascending, stout branches, 15 to 20 cm. in diameter, glaucous when young;
   ribs 6 to 8, broad and rounded; areoles large, 2 to 2.5 cm. apart, brown-felted;
   spines brown from the first, about 10, unequal, some of them 4 cm. long, rigid and stout, not at all swollen at base;
   areoles on ovary and flower-tube hairy;
   mature flowers not seen but evidently large and probably white.

   Collected by Dr. and Mrs. Rose near Matucana, Peru, altitude 2,100 meters, July 9, 1914 (No. 18658).
   This species resembles T. bridgesii but has stouter and darker spines. It is found on the western slopes of the Andes at a much lower altitude than that species.
