Description: The impressions of several lanceolate bracts are available. The bracts are 36–60mm long with a central lamina 4.0–8.5 mm wide, the widest point being at or just above the base. A fringe of densely spaced, 6–9 mm long, <1.2 mm wide, linear to falcate, apically inclined spines or hairs line the lamina margins of most specimens (Fig. 3d, f–h). The hairs are acutely (5°–40°) inserted on the lamina margin and are either straight or slightly falcate. Each hair appears to have a fine median groove or vein. A few bracts are markedly more slender and bear fewer marginal hairs (Fig. 3b, c) and may derive from the inner whorl of a perianth. The bract base is truncate and the apex acutely pointed. The lamina bears weak longitudinal striae and is either flat or gently concave about a longitudinal axis.
Latin ferrugineus—the colour of iron rust.
