Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
A taxonomic study of the representatives of the Apocynoid grade (Apocynaceae) in Eastern Northeast Brazil is presented, and includes an identification key, morphological descriptions, comments, illustrations, photos, and a table. The study area includes the States of Ceará, Rio Grande do Norte, Paraíba, Pernambuco and Alagoas. The botanical material was collected, prepared, and deposited at the UFP herbarium. The collections of regional herbaria were analyzed. A total of 28 species were recorded belonging to seven genera, being Mandevilla (nine spp.), Prestonia (six spp.), Forsteronia (five spp.), Macropharynx, Odontadenia, Secondatia e Temnadenia (two spp. each). The State with the highest number of species was Pernambuco (21 spp.) and the most species-rich phytogeographic domain was the Atlantic Forest (21 spp.). Most species are climbers and vines (27 spp.), except Mandevilla dardanoi (subshrub) and M. tenuifolia (climber or erect subshrub). Ten species had their distribution expanded in the study area. The follicles of Mandevilla catimbauensis are illustrated by the first time.

O Estado com maior número de espécies foi Pernambuco (21 spp.) e o domínio fitogeográfico mais rico foi a Mata Atlântica (21 spp.). A maioria das espécies é composta por trepadeiras e lianas (27 spp.), exceto Mandevilla dardanoi (subarbusto) e M. tenuifolia (trepadeira ou subarbusto ereto).
