Table 1 in New segregates from the Neotropical genus Stryphnodendron (Leguminosae, Caesalpinioideae, mimosoid clade)

Table 1. Diagnostic characters of the four Stryphnodendroid lineages. * Microlobius was not sampled in Guinet and Caccavari 1992; a description provided in a later work includes its single species (Caccavari 2002) which suggests that the genus might have its own distinct pollen type.
