Notes on some Astragalus species of Ecuador and Peru

Resumen

The species here discussed are plants of Ecuador and west-central and northern Peru. They represent the few South American species of the genus which have not been discussed in my forthcoming revision of the Astragalus species of Bolivia, Chile and Argentina. Though these few northern species are well marked, to have included them in my larger paper would have disproportionately complicated the keys to the very abundant and generally less well marked more southern species. Practical considerations have, therefore, demanded a separate treatment of the present outlying northern species of South America. Since the Galapagos Islands are territory belonging to Ecuador I have given notes on the identity and probably true home of the two species of Astragalus based upon spe< imens falsely said to have come from those islands.
