Rodulfo Amando Philippi (1808-1904) was a leading figure in Chilean natural history, including botany. His son Federico Philippi (1838-1910) was a botanist during the same period and worked closely with him. We present an orientation to their works and the information available about them. Both Philippis collected widely in Chile; their principal field trips are summarized. The Philippis' material, including types, is deposited primarily at SGO, but numerous specimens were distributed to other herbaria. The identification of type material is frequently complicated by sparse label data and many duplicates; lectotypes remain to be selected for many names. Although both Philippis published widely in a variety of journals and languages, their descriptions of Chilean plants were published principally in Chilean journals.
