Treatment

2.1. Amphilophium crucigerum ( Linnaeus 1753: 624) L.G.Lohmann View in CoL in Hokche et al. (2008: 270) ( Figs. 3 d–e View FIGURE 3 , 5 d View FIGURE 5 ).

Diagnosis:— Amphilophium crucigerum can be recognized by the tomentose stem ( vs. puberulous in A. paniculatum ), ovate leaflet ( vs. elliptic in A. paniculatum ), smooth calyx ( vs. ondulate in A. paniculatum ), and the strongly curved corolla ( vs. straight in A. paniculatum ).

Reproductive Period:— Flowering in November, fruiting in May.

Distribution and Habitat:— It occurs from Mexico to western South America, where it grows between 0–1900m elevation ( Pool 2007, Lohmann 2010, Lohmann & Taylor 2014). Within the study area, it was registered in Céu Azul, Matelândia, Foz do Iguaçu, and in the PARNA Iguazú , really common, but usually high on the trees, difficulting its collection.
