We have followed most recent writers in combining Cereus dautwitzii with Cereuslanatus, although we have not seen the type of either. We know, however, that Cereusdautwitzii came from Huancabamba, Peru, while Cactus lanatus, upon which Cereus lana-tus was based, came from Guancabamba, Ecuador; the names, varying only in the initialletter, are different spellings for the same place. The northern boundary-line of Peru haspushed north since Humboldt visited this region; his station of Guancabamba is now inPeru instead of Ecuador. The sweet, edible fruit is called soroco in southern Ecuador; it is also called piscolColorado, according to Fig. 91.—Espostoa lanata. The typical form was collected by J. N. Rose, A. Pachano, and George Rose in theCatamayo Valley, southern Ecuador, October 3, 1918 (No. 23326) and the other form wascollected 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. has sent us photographs of a cactus which we would refer here. One was takennear Chilete, Peru, altitude 1,000 feet, and the other between Menocucho and Otuzco,Peru, altitude 3,000 feet. Pilocereus haageanus (Monatsschr. Kakteenk. 6: 96. 1896) is sometimes referred tobut was never published. BROWNINGIA. 63 Illustrations: Diet. Gard. Nicholson 3:f. 152; Fl.
