Western New Mexico, at 6,500 feet altitude, Loew. This rare plant was 
also obtained in 1872 by Professor Porter at the “Soda Springs, 35 miles 
northwest of Cafion City”, and a good description of it furnished in the 
Flora of Colorado —Puiate XII. Natural size. Fig. 1. Vertical section 
through the receptacle, showing ray- and disk-flowers; also involucral scale 
and embracing chaff. 2. Single involucral scale. 3. Ray-flower. 4. Chaff

BatLeyaA MuLTIRADIATA, Gray (Pl. Fendl. p. 105).—More or less 
densely floccose-woolly, usually but little branched at the base ; leaves once 
or twice pinnatifid ;; peduncles 4-12’ long, and terminated by a large head
