“…These woods are constituted by: 10 to 30 percent of vessels, 0 to 5 percent of axial parenchyma, 10 to 20 percent of rays and 60 to 70 percent of fibers. Several of these characteristics have been observed in riparian species such as Colliguaya brasiliensis [60] and Aspidosperma riedelii [62].…”

Riparian vegetation comprises plant communities that grow laterally to rivers and streams. They have multiple adaptations, which allows them to persist in these variable and dynamic habitats. This chapter focuses on the morphological and anatomical adaptations of vegetative organs, due to the fact that they are more vulnerable to environmental changes that occur in riparian ecosystems. We also discuss some dispersal mechanisms in riparian species exposed to flooding conditions. Most morphoanatomical adaptations in riparian plants reflect constraints imposed by long periods of waterlogging or complete submergence, as well as the high diversity of strategies that species have developed in order to cope with flooding. Furthermore, riparian ecosystems are being impacted by an increasing artificialization of rivers and banks with losses, or profound changes, in the natural riparian vegetation a problem that will increase with the ongoing climate change, and which must be contained. In order to reduce the vulnerability of these ecosystems, a deeper knowledge of the morphoanatomical attributes that make possible the successful adaptation of riparian flora is necessary so as to implement appropriate measures for the rehabilitation and sustainability of riparian ecosystems.

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.
