Notopleura (Benth. & Hook.f.) Bremek. includes about 100 species of shrubs and small trees distributed widely in the New World tropics. Notopleura plants are terrestrial or epiphytic herbs or subshrubs that are found in moist to wet tropical forests, from low to high elevations. The plants are usually fleshy to rather succulent, and the terrestrial species are often unbranched. The genus is distinguished by its stipules with glandular or laminar, often well developed appendages and its inflorescences that are terminal or often pseudoaxillary. The flowers are white, relatively small, and presumeably pollinated by insects. The carnose fruits are white, orange, red, or sometimes black, and presumeably dispersed by birds. Some Notopleura species are distylous.

Notopleura species have previously been included by most authors in Psychotria Subg. Heteropsychotria Steyerm., but recent consideration of both morphological (Taylor, 1996, 2001) and molecular (Andersson & Rova, 1999; Nepokroeff, 1997; Nepokroeff et al., 1999) characters show that this genus is better treated separately. An overview of Notopleura was presented by Taylor (2001), who presented a key to its species and recognized two subgenera. Notopleura subg. Notopleura includes the majority of species in the genus, which are terrestrial and have pseudoaxillary inflorescences; Notopleura subg. Viscagoga (Baill.) C.M. Taylor includes epiphytic species with terminal inflorescences.

When Notopleura was included in Psychotria, several published species were synonymized by most authors with Psychotria macrophylla, which was by far the most commonly collected species and considered morphologically variable and difficult to characterize. Taylor (2001, 2003) showed that Notopleura macrophylla is a clearly and much more narrowly characterizable species, and separated a number of species from it.
