Potosi: mountains near San Miguelita, Aug. 1876, Schaffner 215 
(TyPEs in Gray Herb., hb. Berlin); without definite locality, 1878, 
P arry & Palmer 424 (Gray Herb.). — The specimen of Schaffner’s 
in the Berlin Herbarium (included in a collection now at the Gray 
Herbarium on loan) is dated 1879 and numbered 656 of Vigener’s 
distribution, but as the number 215 is also written on the label 
under Schaffner’s name it is probably of the same collection as the 
plant in the Gray Herbarium. The species, although of conyzoid 
appearance, 1s technically a true Erigeron in the possession of a 
definite although minute ligule.
