نبذة مختصرة : Premise of research. Fossil remains of a water lily, Nuphar carlquistii DeVore, Taylor & Pigg sp. nov. (Nymphaeaceae), are described from the latest early Eocene Republic flora of north-central Washington. Specimens include several fruits, one with in situ seeds, others with remnants of stamens and stamen attachment scars, and dispersed seeds found both within a mucilaginous dispersal matrix and separately. Associated structures, including a stigmatic disk, isolated tepals, and several rhizome segments bearing nested clusters of roots and leaf scars, are included in N. cf. carlquistii.Methodology. Fossils preserved in a lacustrine shale were degaged to reveal details, photographed with LM, and compared morphologically with extant material of related plants.Pivotal results. The study documents the most complete fossil Nuphar known to date. The combination of multiple organs, including fruits, seeds, stamens, and rhizomes with leaf scars and clustered root scars, demonstrates that Eocene Nuphar had vegetati...
