Species: [1]
Hornbeams are hardwood trees in the flowering plant genus Carpinus in the birch family Betulaceae. The 30–40 species occur across much of the temperate regions of the Northern Hemisphere.
Military production during World War II was the arms, ammunition, personnel and financing which were produced or mobilized by the belligerents of the war from the occupation of Austria in early 1938 to the surrender and occupation of Japan in late 1945.
Neviusia, the snow-wreaths, is a genus of ornamental plants, which are native to the United States, containing two extant species and one extinct species known from fossil leaves. This genus is a rare example of a disjunct range occurring in North America. The type species, Neviusia alabamensis, occurs in several southeastern states, while second extant species, Neviusia cliftonii, is endemic to the Mt Shasta region of California, and the extinct species Neviusia dunthornei is found in shale deposits in the Okanagan Highlands of Washington and British Columbia. It is named for Episcopal priest and botanist Reuben Nevius.
Phaeothamniophyceae is a class of heterokonts. It contains two orders, Phaeothamniales and Aurearenales, and consists of species separated from Chrysophyceae.
Plagioselmis is a genus of cryptophytes, including the species Plagioselmis punctata.
Tilia johnsoni is an extinct species of flowering plant in the family Malvaceae that, as a member of the genus Tilia, is related to modern lindens. The species is known from fossil leaves found in the early Eocene deposits of northern Washington state, United States and a similar aged formation in British Columbia, Canada.
Abies milleri, an extinct species of fir known from fossil remains found in deposits from the early Eocene Ypresian stage in Washington State, USA, is the oldest confirmed record for the fir genus.
Trochodendron nastae is an extinct species of flowering plant in the family Trochodendraceae known from fossil leaves found in the early Eocene Ypresian stage Klondike Mountain Formation deposits of northern Washington state. T. nastae is one of the oldest members of the genus Trochodendron, which includes the living species T. aralioides, native to Japan, southern Korea and Taiwan and the coeval extinct species T. drachukii from the McAbee Fossil Beds near Cache Creek, British Columbia.
Corylus johnsonii is an extinct species of hazel known from fossil fruits found in the Klondike Mountain Formation deposits of northern Washington state, dated to the early Eocene Ypresian stage. Based on described features, C. johnsonii is the oldest definite species in the genus Corylus.
Trochodendron drachukii is an extinct species of flowering plants in the family Trochodendraceae known from a fossil fruiting structure found in the early Ypresian age Eocene fossils found in British Columbia, Canada. T. drachukii is one of the oldest members of the genus Trochodendron, which includes the living species T. aralioides, native to Japan, southern Korea and Taiwan and the coeval extinct species T. nastae from Washington state, United States.
Neoephemera antiqua is an extinct species of square-gill mayfly in the family Neoephemeridae that is known from early Eocene, Ypresian stage, lake deposits near the small community of Republic in Ferry County, Washington, USA.
The Klondike Mountain Formation is an Early Eocene (Ypresian) geological formation located in the northeast central area of Washington state. The formation, named for the type location designated in 1962, Klondike Mountain north of Republic, Washington, is composed of volcanic rocks in the upper unit and volcanics plus lacustrine (lakebed) sedimentation in which a lagerstätte with exceptionally well-preserved plant and insect fossils has been found, along with fossil epithermal hot springs.
Fothergilla malloryi is an extinct species of flowering plant in the family Hamamelidaceae known from fossil leaves found in the early Eocene Klondike Mountain Formation deposits of northern Washington state. The F. malloryi leaves are the earliest appearance in the fossil record of a member of the witchalder genus Fothergilla, which includes the living species F. gardenii, and F. major, both of which are native to the southeastern United States. The genus also includes three or four other fossil species with two Asian Miocene species, F. viburnifolia from China, F. ryozenensis from Japan along with one Miocene North American species, F. praeolata of Oregon. Fothergilla durhamensis described from Eocene sediments in King County, Washington is considered dubious in placement, and it was transferred to the genus Platimeliphyllum by Huegele et al. (2021).
Corylopsis reedae is an extinct species of flowering plant in the family Hamamelidaceae known from fossil leaves found in the early Eocene Klondike Mountain Formation deposits of northern Washington state. C. readae is one of the oldest occurrences of the winter-hazel genus Corylopsis, which includes between seven and thirty species, all found in Asia. Fossils from two other occurrences are of similar age to C. readae, with Paleocene specimens from Greenland being placed in the form taxon Corylopsiphyllum and an Eocene Alaskan fossil being included in Corylopsis without species placement.
Stonebergia is an extinct genus in the rose family, Rosaceae, which contains the single species Stonebergia columbiana. The genus was described from a series of isolated fossil leaves in shale from an early Eocene location in southern British Columbia.
| authority = Wolfe & Wehr Langeria is an extinct genus of flowering plants in the family Platanaceae containing the solitary species Langeria magnifica. Langeria is known from fossil leaves found in the early Eocene deposits of northern Washington state, United States and similar aged formations in British Columbia, Canada.
Cretomerobius is an extinct genus of lacewings in the neuropteran family Hemerobiidae known from fossils found in Asia. The genus currently contains a single species, the Aptian C. disjunctus.
Tsukada is an extinct genus of flowering plant in the family Nyssaceae related to the modern "dove-tree", Davidia involucrata, containing the single species Tsukada davidiifolia. The genus is known from fossil leaves found in the early Eocene deposits of northern Washington state, United States and a similar aged formation in British Columbia, Canada.
Barghoornia is an extinct genus of flowering plants in the family Burseraceae containing the solitary species Barghoornia oblongifolia. The species is known from fossil leaves found in the early Eocene deposits of northern Washington state, United States.
Pteronepelys, sometimes known as the winged stranger, is an extinct genus of flowering plant of uncertain affinities, which contains the one species, Pteronepelys wehrii. It is known from isolated fossil seeds found in middle Eocene sediments exposed in north central Oregon and Ypresian-age fossils found in Washington, US.
