“…Of all species occurring in Brazil, 20 are found in the northeastern region and four in Rio Grande do Norte (Flora do Brasil 2020, under construction). Species from this genus are known for providing good-quality wood and alkaloids used in pharmacology and traditional medicine (Marcondes-Ferreira 1988;Pereira et al 2019).…”

We present here a taxonomic study of Apocynaceae from the Atlantic Forest remnants in the state of Rio Grande do Norte (RN), Northeast Brazil. Twenty-four species in 18 genera, distributed in Apocynoid grade (3 genera/5 species), Asclepiadoideae (8 genera/10 spp.), and Rauvolfioid grade (7 genera/9 spp.) were recorded. The most species-rich genera were Aspidosperma, Ditassa, and Mandevilla with three species each. The other genera were represented by one species each. Five genera and seven species were recorded in Rio Grande do Norte for the first time. Descriptions, identification key and comments on distribution and taxonomy of both genera and species are presented, as well as illustrations and figures.

Abstract—Aspidosperma (Apocynaceae) is composed of trees and shrubs; the genus includes 70 species, 42 of which occur in Brazil. The midwestern region has the second highest diversity, with 30 species, after the northern region, and Mato Grosso do Sul state has 15 species. This study provides macroscopic and microscopic wood features for ten species from A. section Aspidosperma and A. section Pungentia (Apocynaceae) from Mato Grosso do Sul state, Brazil. These characteristics can aid in the identification of Aspidosperma species because the nine species of these two sections have many morphological similarities; moreover, the wood of these species is economically important for timber production. Through macroscopic and microscopic analysis procedures, the characteristics of the wood and the organoleptic properties allowed recognition and distinction of the studied taxa. The characters of diagnostic value for recognition of the sections are vessel frequency and arrangement, and ray width. Individually, each species had a set of characteristics that allowed its identification: wood color; vessel arrangement; vessel length; ray visibility, ray composition and width; presence of crystals, starch grains and lipids in axial and/or ray parenchyma cells. The results may support conscientious exploitation by industries by facilitating the correct identification of the species, and will also help in the detection of illegal timber logging.
