Lineata, with around 30 species of trees, shrubs and lianas, occurs from southern Mexico to northern Argentina and is characterized by the presence of spinescent stipules and leaflets with cladodromous venation. The difficulty of distinguishing species in this section is compounded by a proliferation of taxonomic names. The taxonomy, morphology, and geographic distribution of Machaerium hirtum and four allied species of section Lineata were investigated. The results include the circumscription of the M. hirtum alliance to include M. aculeatum, M. eriocarpum, M. hirtum, M. isadelphum, and M. sericiflorum, as well as two basionyms and 26 synonyms (of which 11 are listed here for the first time), and the designation of the neotype of M. sericiflorum, the lectotypes of M. angustifolium, M. angustifolium var. β, M. angustifolium fo. glauca and M. armatum, and the epitype of M. hirtum. In addition to the wide variation and overlap of certain morphological characters, the problems in the circumscription of this complex may also be related to their broad distribution range, which corresponds to that known for the genus as a whole. Vegetative and reproductive characters were used to delimit the five species. Among the important characters are the dimensions and indumentum of the leaflets, bracteoles, calyx, and banner petal, and the presence of diadelphous stamens. Machaerium isadelphum and M. hirtum have the largest geographic range, while M. eriocarpum is restricted to southwestern South America and M. aculeatum and M. sericiflorum are endemic to Brazil. Identification keys, descriptions, illustrations, geographic distributions, and habitat are used to distinguish the species.
