Abstract

THE work of the botanical pioneers in South America appeared for the most part in the form of pamphlets or monographs which soon became exhausted and inaccessible to later generations, or else it was published in equally inaccessible, obscure periodicals. Most of it was, however, work of great importance and the foundation upon which subsequent research, at all events for certain regions, has been built. For this reason the recent re-publication of some of the outstanding earlier work is a welcome addition to the botanist's armoury, and it is to be hoped that more will follow.
