In 1918, while in Ecuador, Dr. Rose attemptedto reach the exact locality of Humboldts Cactuslanatus, but was unsuccessful. In the CatamayoValley somewhat north of Humboldts station andin what is doubtless a part of the same deserthe collected this species and upon this our descrip-tion above is largely based. These plants are sodifferent in habit from other plants collected byDr. Rose in central Peru that we have been verymuch in doubt whether they should all be referredhere or a part separated as a new species. Thatthere is more than one species in this genus has been further suggested since receiving aphotograph from G. M. Dyott, taken atChagual, on the west bank of the Marafion River,in northern Peru. In this photograph are shown several very striking cactus plants, per-haps of this genus, but very unlike any we have heretofore seen.
