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, 1 91 4 (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. 



Pilocereus haageanus (Monatsschr. Kakteenk. 6:96. 1896) is sometimes referred to 

 but was never published.
