Melicope is a genus of about 240 species of shrubs and trees in the family Rutaceae, occurring from the Hawaiian Islands across the Pacific Ocean to tropical Asia, Australia and New Zealand. Plants in the genus Melicope have simple or trifoliate leaves arranged in opposite pairs, flowers arranged in panicles, with four sepals, four petals and four or eight stamens and fruit composed of up to four follicles.
Tetradium is a genus of trees in the family Rutaceae, occurring in temperate to tropical East Asia. In older books, the genus was often included in the related genus Euodia, but that genus is now restricted to tropical species. In cultivation in English-speaking countries, they are known as Euodia, Evodia, or Bee bee tree.
The Burseraceae are a moderate-sized family of 17-19 genera and about 540 species of woody flowering plants. The actual numbers given in taxonomic sources differ according to taxonomic revision at the time of writing. The Burseraceae are also known as the torchwood family, the frankincense and myrrh family, or simply the incense tree family. The family includes both trees and shrubs; its species are native to tropical regions of Africa, Asia, Australasia, and the Americas.
Caldesia is a genus of aquatic plants. It includes three living species widespread across Europe, Asia, Africa and Australia. The genus "has an extensive Oligocene through Pleistocene fossil record in Eurasia," and has been found in fossil strata of the United States as well. Ten fossil species have been described for the genus.
Embothrium is a genus of two to eight species in the plant family Proteaceae, native to southern South America, in Chile and adjacent western Argentina; the genus occurs as far south as Tierra del Fuego. Common names include Chilean firebush in English, notro in Argentina, ciruelillo, fosforito or notro chileno in Chilean Spanish.
Symplocos is a genus of flowering plants in the order Ericales. It contains about 300 species distributed in Asia and the Americas. Many species grow in humid tropical regions. This is sometimes considered to be the only genus in family Symplocaceae. Plants in this family are shrubs and trees with white or yellow flowers. The oldest fossils of the genus date to the lower Eocene of Europe and North America, with the genus being present in Europe as late as the Pliocene. Fossil seeds of †Symplocos granulosa are frequent in sediment rock layers of the Late Oligocene to the Late Miocene of Denmark, Germany, Austria and Poland. The fossil seeds are very similar to the seeds of the extan southern Chinese species Symplocos glandulifera and Symplocos sulcata. Fossil seeds of †Symplocos paucicostata are known from the Middle Pliocene sediment rock layers in Reuver, the Netherlands and from the Late Pliocene sediment rock layers in northern Italy. The fossil seeds are very similar to the seeds of the extant East Asian species Symplocos paniculata
Presbyornis is an extinct genus of anseriform bird. It contains two unequivocally accepted species; the well-known P. pervetus and the much lesser-known P. isoni. P. pervetus was approximately the size and shape of a goose, but with longer legs; P. isoni, known from a few bones, was much larger, more than swan-sized. Other fossils, more doubtfully assigned to this genus, are also known.
Aegialornis is a genus of prehistoric apodiform birds. It formed a distinct family, the Aegialornithidae, and was in some ways intermediate between modern swifts and owlet-nightjars, lacking the more extreme adaptations to an aerial lifestyle that swifts show today, but already having sickle-shaped wings like them. They do not appear to be a direct ancestor of modern swifts, however, but rather a group that retained an overall basal morphology. Altogether, they were not too dissimilar from modern treeswifts.
Priscacara, is a genus of extinct temperate bass described from Early to Middle Eocene fossils. It is characterized by a sunfish-like body and its stout dorsal and anal spines. The genus is best known from the Green River Formation of Wyoming, Utah and Colorado. Mass deaths of Priscacara suggest it formed schools.
Tetradium daniellii, the bee-bee tree or Korean evodia, is a species of flowering plant in the family Rutaceae. It is native to Korea and southwestern China.
Pontogeneus is a genus of extinct cetacean known from fossils recovered from Late Eocene sediments of the southeastern United States.
Azolla primaeva is an extinct species of "water fern" in the family Salviniaceae known from Eocene fossils from the Ypresian stage, found in southern British Columbia.
Nypa fruticans, commonly known as the nipa palm or mangrove palm, is a species of palm native to the coastlines and estuarine habitats of the Indian and Pacific Oceans. It is the only palm considered adapted to the mangrove biome. The genus Nypa and the subfamily Nypoideae are monotypic taxa because this species is their only member.
Titanomyrma is a genus of extinct giant ants which lived during the Eocene. The type species Titanomyrma gigantea and the smaller Titanomyrma simillima are known from the Eocene of Germany, while the third species Titanomyrma lubei, is known from Wyoming, United States. The presence of Titanomyrma in North America was considered to indicate "the first reported cross-Arctic dispersal by a thermophilic insect group".. However a queen reported from Upland temperate shales in British Columbia raised questions on the exact thermophilic nature of the genus. The type species of this genus, T. gigantea, is the largest-known fossil or extant species of ant in the world.
Aenigmastacus crandalli is a species of fossil freshwater crayfish. It was found in early Eocene Okanagan Highlands lake deposits in British Columbia, and was described in 2011. It is the first member of the Gondwana-distributed family Parastacidae to be found in the Northern Hemisphere, and is the only species in the genus Aenigmastacus. Twelve specimens are known, with a total body length of 3–5 cm (1.2–2.0 in). On some specimens, details of the internal anatomy can be seen due to the exceptional preservation.
Tetradium ruticarpum is a tree that comes from China and Korea. It was previously classified in the genus Euodia as Euodia ruticarpa. The fruit is usually used, denoted sometimes as fructus. It has a strong bitter taste, and is used in traditional Chinese medicine (TCM) and is a recognized herb in Kampo. Both the former genus name and the species name are often misspelled, and the plant usually appears in sources dealing with traditional Chinese medicine as "Evodia(e) rutaecarpa".
Casaleia is an extinct genus of ants in the formicid subfamily Amblyoponinae described by Pagliano & Scaramozzino in 1990 from fossils found in Europe. The genus contains four species dating from the Eocene to Miocene, Casaleia eocenica, Casaleia inversa, Casaleia longiventris, Casaleia orientalis.
Eriocapitella is a genus of flowering plants in the buttercup family Ranunculaceae. Plants of the genus are native to Asia. The generic name Eriocapitella roughly translates to "growing in a small woolly head", which refers to the hairy ovary and fruit of some members of the genus. Cultivated plants are commonly known as fall-blooming anemones.
Eriocapitella japonica is a species of flowering plant in the buttercup family Ranunculaceae. The specific epithet japonica means "from Japan", which is a misnomer since the species is introduced in Japan. It is native to China, Taiwan, and Vietnam.
