Annonaceae form the most diverse family within the Magnoliales. In 1990 an Index to generic names of Annonaceae was published and in 1994 an Index to Neotropical species of Annonaceae was compiled. Especially the latter proved an immensely useful tool for Neotropical botanists. Here, we present an updated Index of all valid names in Neotropical Annonaceae on the genus and species level. It also includes nomina nuda and orthographic variants. Reference and year of first publication, synonymy, and typification are mentioned. Several new combinations are made. In addition, some lectotypifications are proposed. A supplementary list is added of all Neotropical type collections.
