Una nueva especie de Onoseris (Compositae) procedente del Perú. 2:1-4.

A NEW SPECIES OF ONOSERIS (COMPOSITAE) FROM PERU, by Ramón FERREYRA.~In 1944 the “JOURNAL OF THE ARNOLD ARBORETUM” of HARVARD UNIVERSITY, Cambridge, MASS. U.S.A. published my paper REVISION DEL GENERO ONOSERIS with the description of 25 species and nine plates. This genus has a wide distribution which comprise from Mexico with Onoseris onoseroides. to Argentina with Onoseris alata. During a collecting trip to Cajamarca, north Peru, made in 1946 the author found a new species of ONOSERIS which describes as Onoseris Macbridet sp. nov. It is a pleasure to dedicate this new species to my friend Francis Macbride distinguished botanist author of the FLORA OF PERU.
