Corythophora View in CoL clade (100% BS; Fig. 2A View FIGURE 2 , 10 View FIGURE 10 )
This clade includes all four species of Corythophora recognized by Mori & Prance (1990). Species of Corythophora are restricted to Surinam, French Guiana, and central and eastern Amazonian Brazil ( Huang, 2010). Morphological synapomorphies of Corythophora include the presence of squamae on the surface of the inflorescence rachis (character 12, Fig. 3A View FIGURE 3 ) and anther dimorphism (character 36). In addition, the species of Corythophora possess dorsiventrally thickened and closed androecial hoods (character 33; Fig. 10A, D, F, I View FIGURE 10 ). Within the clade, the species are divided into two subclades ( Fig. 2A View FIGURE 2 ): one with C. labriculata ( Eyma 1932: 75) S. A. Mori & Prance ( Mori 1981a: 365) and C. amapaensis Pires ex S. A. Mori & Prance ( Mori 1981a: 365) , and the other with C. alta R. Knuth (1939: 51) and C. rimosa Rodrigues (1974: 5) . The latter subclade differs from the former by the presence of ligular (character 32) instead of staminal ring antherodes, non-imbricate calyx-lobes, and a hypanthium and calyx-lobes that are not differentiated in texture and color. The monophyly of Corythophora in this study is congruent with previous studies ( Mori & Prance, 1990; Mori et al., 2007; and Huang et al., 2011).
