The northern boundary-line of Peru has pushed north since Humboldt visited this region; his station of Guancabamba is now in Peru instead of Ecuador. The sweet, edible fruit is called soroco in southern Ecuador; it is also called piscol Colorado, according to FIG. yi.—Espostoa lanata. The typical form was collected by J. N. Rose, A. Pachano, and George Rose in the Catamayo Valley, southern Ecuador, October 3, 1918 (No. 23326) and the other form was collected by Dr. and Mrs. Rose near Matucana, central Peru, altitude about 7,000 feet, July 9, 1914 (No. 18649). Dr. Rose also collected a living plant above Chosica (No. 18537) and herbarium specimens between Matucana and San Bartelome (No. 18748). Dr. W. H. Osgood has sent us photographs of a cactus which we would refer here. One was taken near Chilete, Peru, altitude 1,000 feet, and the other between Menocucho and Otuzco, Peru, altitude 3,000 feet. 1'ilih-crcns haagcattHS (Monatsschr.
