Cross section, the arrow is pointing to the scar of a macrohair in D. arenicola [Matos et al. 70 (HUEFS)]. D. Bulliform cells with a macrohair in the central cell, adaxial surface. E–G. D. cumbucana [Harley et al. 15930 (HUEFS)]. E. Abaxial surface with microhairs. F. Adaxial surface with microhairs. G. Cross section. H–I. Prickle hairs. H. D. arenicola, transversal view. I. D. cumbucana, paradermic view. [Bc = bulliform cells; Tc = microhairs; Mh = macrohairs; Pr = Prickle hairs; VB = vascular bundle. Bars: 200 µm (except: F= 100 µm and I= 50 µm)]
