Text-fig. 5. SRXTM images of Miranthus elegans gen. et sp. nov.; Mira locality, Portugal. a, b: Transverse sections of flower (a, orthoslice xy0665 close to the apex of placenta; b, orthoslice xy0800 in middle part of placenta) showing remains of calyx with distinct bundles (arrows), ovary wall (ow) and numerous ovules (ov) on the central mushroom-shaped globose placenta (pl) with central column (cc). c: Transverse section of flower (orthoslice xy0620) through perianth and ovary (ow) at a level above the placenta showing ovules (ov) and cellular preservation of the sepal bundles (arrows shown for one sepal); note abaxial surface of sepals with thick-walled epidermal cells, thick cuticle, and fine pointed verrucae. d: Longitudinal section of flower (orthoslice xz0500) showing perigynous position of calyx and semi-inferior ovary (ow, ovary wall) with a central placenta (pl), central column (cc) and numerous ovules (ov); note spiny verrucae on abaxial surface of calyx lobes. Specimens, Mira 100-S153145 (a, b), Mira 100-S170155 (c, d, holotype). Scale bars = 600 µm (a–d).

Text-fig. 7. SEM (a) and SRXTM (b–e) images of Miranthus kvacekii sp. nov.; Mira locality, Portugal. a: Lateral view of flower bud showing corolla lobes extending beyond calyx; note surface of pedicel, calyx and corolla with small equiaxial epidermal cells and indumentum of densely spaced, short stiff trichomes. b, c: Longitudinal sections through floral bud in two directions perpendicular to each other (a, orthoslice yz1024; b, orthoslice xz0950) showing corolla (co), calyx (ca), stamens (st) and semi-inferior ovary with thin ovary wall (ow) and central mushroom-shaped globose placenta (pl) bearing numerous ovules (ov). d, e: Transverse sections through floral bud above placenta (d, orthoslice xy0915; e, orthoslice xy1095) showing calyx (ca), corolla (co), ovary wall (ow) and ovules (ov); yellow outlines indicate the positions of anthers (d) and filaments (e); orange outlines indicate the position of three of the possible staminodes.
