Levantamento, Informatização, Classificação e Divulgação dos Tipos Nomenclaturais do Herbário IAN (Embrapa Amazônia Oriental)

Abstract

Nomenclatural types are botanical specimens used in the description of a taxon new to science, and are indispensable for the preparation of taxonomic revisions and monographs. Thus, the preservation and location of these specimens is extremely important for taxonomy and systematics. Consultation of type specimens is often necessary to clarify doubts during the identification process. The objective of the present work is to survey, typify, computerize and divulge the Nomenclatural Types of the Leguminosae family that exist in the IAN herbarium. A survey of the possible Types that were in the general collection of the IAN Herbarium was done, followed by a bibliographic survey of the princeps works. The typification was done according to the International Code of Botanical Nomenclature, based on the protologues and the information on the labels (Schedulae). The data organization followed the following order: scientific name, abbreviated author according to Brummit and Powell (1992), citation of the princeps work, transcription of the type citation as it appears in that work, acronym of the herbarium where the specimen is, and label information that does not appear in the citation. Specimens certified as Types were inserted, along with a copy of their respective diagnoses, in red covers according to the international standard. They were photographed with a digital camera (FUJI FILM Fine Pix 5.7.000). The images and information were linked through BRAHMS - Botanical Research and Herbarium Management System software (www.brahmsonline.com), which has been used in the computerization of Amazonian herbaria. We characterized 205 specimens of the Leguminosae family, 100 belonging to the Caesalpinioideae, 25 to the Mimosoideae and 80 to the Papilionoideae.
