Discussion

Varieties 18–20 (1 in the flora).

Senna pendula is often confused with close relative S. bicapsularis, which is absent from North America and has shorter pedicels, only to 5 mm (H. S. Irwin and R. C. Barneby 1982; B. Marazzi et al. 2006b).

Varieties 7 (1 in the flora).

Recent molecular phylogenetic analyses of Senna hirsuta (B. Marazzi et al. 2006; Marazzi and M. J. Sanderson 2010) suggest that this species is paraphyletic and may actually represent more than one species.
