The IAN Herbarium (Embrapa Eastern Amazon) has an extensive collection of Leguminosae Juss., which was classically divided into three subfamilies; however, in 2017, a review was published proposing a new classification, dividing it into six subfamilies, among them Detarioideae. In 2018, Detarioideae was divided into six tribes, the largest of them Amherstieae. This large taxonomic recircumscription justifies a database update. The objective of the study was to carry out the survey, organization, computerization, and online availability of representatives of the tribe Amherstieae (Leguminosae – Detarioideae) at the IAN Herbarium. First, a survey was carried out on which genera of Amherstieae were represented in the collection. Their specimens were located and had their information inserted in the database and subject to quali-quantitative analyses. 976 specimens belonging to 10 of the 50 genera of Amherstieae were observed. The genus with the most specimens (600) was Macrolobium. The samples had origins in 9 countries, with 885 from Brazil, and from these, 438 from Pará, with 54 municipalities represented. The distribution of collections by mesoregions showed great heterogeneity with a concentration in Northeastern Pará and the Metropolitan Region of Belém. In conclusion, it is of fundamental importance that the Amherstieae data are disseminated, contributing to a greater offer of information regarding this group. Therefore, their data were included in the IAN Virtual Herbarium in January/2019, which can be consulted online from anywhere in the world, assisting in future research.</p> ER -
