“…Aside from the prominent unravelling of Acacia s.l., numerous other generic changes have been made over the last three decades, notably by Nielsen (1981), Rico Arce (1991Arce ( , 1992, Lorence & Wood (1994), Polhill (1994), Barneby & Grimes (1996, 1997, Barneby (1998), Jobson & Luckow (2007), and Villiers (2002), as summarized by Brown (2008) for the Ingeae, and synthesized by Lewis & al.

“…The mimosoid genera Zygia P.Browne and Marmaroxylon Killip (Fabaceae) include some 50 and 9-13 species, respectively, as currently circumscribed (Rico Arce, 1991;Barneby & Grimes, 1997). They consist of small or sometimes medium-sized, cauliflorous and/or ramiflorous trees or shrubs (Fig.…”

“…Marmaroxylon was originally described by Killip (in Record, 1940) to accommodate the Amazonian species Pithecellobium racemosum Ducke. Rico Arce (1991) pinnae, a feature differentiating them from species of Zygia, which have leaves with one pair of pinnae only.…”

“…Thus, if following Rico Arce's (1991) concept of Marmaroxylon, these species should instead have been treated in Marmaroxylon. Barneby & Grimes (1997) divided Zygia into nine sections, five of which include, or consist entirely of, representatives of species referred to Marmaroxylon by Rico Arce (1991). Despite this, and likely because Barneby & Grimes (1997) themselves expressed an uncertainty about their classification, Marmaroxylon has continued to be recognized in the literature (e.g., Pennington & al., 2004;Lewis & Rico Arce, 2005;Ståhl & al., 2015); but see LPWG (2017).…”

“…We sampled broadly, with representatives from all alliances in the Ingeae tribe (Lewis & Rico Arce, 2005), and included two species of Acacia s.str., four species of Senegalia Raf., and Vachellia farnesiana (L.) Wight & Arn. to (1) test the monophyly of Zygia, the monophyly of the sections within Zygia and the positions of the morphologically odd species as listed by Barneby & Grimes (1997); (2) test the monophyly of Marmaroxylon as circumscribed by Rico Arce (1991); (3) test the monophyly of several species of both Zygia and Marmaroxylon; and (4) test the relationships of Zygia/Marmaroxylon species to other ingoid taxa and closely related Acacia species (e.g., Brown & al., 2008).…”

The Neotropical legume genera Zygia and Marmaroxylon have traditionally been considered closely related and are sometimes treated as congeners. They have been referred to the mimosoid tribe Ingeae based on their possession of flowers with basally fused stamen filaments. However, their systematic status and position have not been analysed in a phylogenetic context. This study provides the first molecular phylogeny of Zygia and Marmaroxylon and closely related mimosoid legume genera, particularly from the tribe Ingeae. DNA sequence data were derived from the nuclear external transcribed spacer (ETS) and the internal transcribed spacer (ITS), and from the chloroplast psbA-trnH and trnL-trnF regions, and were analysed using Bayesian inference. In all, 29 species of Zygia and 7 species of Marmaroxylon were included in the study along with representative species from the closely related genera Abarema, Acacia

In recent phylogenetic studies of legumes the species Zygia/Ingainundata and Zygiasabatieri have been shown to not belong in neither Inga nor Zygia. Inga inundata was originally placed in the genus Inga based on morphological characters such as having pinnate leaves, but was transferred to the genus Zygia when the pod was discovered. The species was placed in its own section in Zygia, Zygia sect. Ingopsis, due to the similarity in leaf morphology to the species in Inga. Zygia sabatieri is another species placed in its own section in Zygia, Zygia sect. Pseudocojoba, due to similarity in flower morphology to the legume genus Cojoba. The genus Marmaroxylon has been synonymized under Zygia but the species Marmaroxylonocumarense has been shown to be closer related to species of the genus Macrosamanea and is not resolved within Zygia. In this study these results are compared and discussed. Zygia/Ingainundata and Zygiasabatieri are morphologically distinct from Inga and Zygia, and from each other, and taxonomic adjustments are made. Two new genera are described, Ingopsis gen. nov. to accommodate Zygia/Inga inundata and Pseudocojoba gen. nov. to accommodate Zygia sabatieri. In addition, Marmaroxylon ocumarense is transferred to the genus Macrosamanea where it fits phylogenetically and morphologically.
