Emmotum harleyi. Scanning electron micrographs. (A) Flower at anthesis. (B) Floral bud, outer suface. Two petals with valvate aestivation and postgenital connection (arrow). Distribution of hairs reflects position of sepals in younger bud: in areas without hairs the sepals were appressed to the petals in bud (star). (C) Petal of anthetic flower, ventral side. Midrib with moniliform hairs. (D) Anthetic flower, showing synsepalous calyx and gynoecium (perianth and androecium removed). (E) Gynoecium of anthetic flower, from above, fertile side down. Surface with pressure marks of anthers and of moniliform hairs from petals. (F) Gynoecium of anthetic flower, from the side, fertile side at right. Surface with pressure marks of moniliform hairs from petals. Scale bars: (A) = 1 mm; (B, C, E, F) = 0·1 mm; (D) = 0·2 mm.
