A. marantoidea (Calderon et al. 2381, Brazil): d, section of lamina showing minor vascular bundle, fusoid cells, and primary vascular bundle; e,g, midrib section from a robust leaf, showing characteristic shape and complex vasculature;f, section of lamina including midrib, cut from a small leaf. Scale bar: a,c-e = 100 µm; b = 50 µm; f= 200 µm; g = 250 µm.
