Ginkgoales are a gymnosperm order containing only one extant species: Ginkgo biloba, the ginkgo tree. It is monotypic, within the class Ginkgoopsida, which itself is monotypic within the division Ginkgophytaghing-KOF-it-ə. The order includes five families, of which only Ginkgoaceae remains extant.
Campsis grandiflora, commonly known as the Chinese trumpet vine, is a fast-growing, deciduous creeper with large, orange, trumpet-shaped flowers in summer. It can grow to a height of 10 meters. A native of East Asia, it is less hardy than its relative Campsis radicans.
Codiaeum variegatum is a species of plant in the genus Codiaeum, which is a member of the family Euphorbiaceae. It was described by Carl Linnaeus in 1753. It is native to Indonesia, Malaysia, Australia, and the western Pacific Ocean islands, growing in open forests and scrub.
Pleuromeia is an extinct genus of lycophytes related to modern quillworts (Isoetes). Pleuromeia dominated vegetation during the Early Triassic all over Eurasia and elsewhere, in the aftermath of the Permian–Triassic extinction event. During this period it often occurred in monospecific assemblages. Its sedimentary context in monospecific assemblages on immature paleosols, is evidence that it was an opportunistic pioneer plant that grew on mineral soils with little competition. It spread to high latitudes with greenhouse climatic conditions.
Buddleja crispa, the Himalayan butterfly bush, is a deciduous shrub native to Afghanistan, Bhutan, North India, Nepal, Pakistan and China, where it grows on dry river beds, slopes with boulders, exposed cliffs, and in thickets, at elevations of 1400–4300 m. Named by Bentham in 1835, B. crispa was introduced to cultivation in 1850, and came to be considered one of the more attractive species within the genus; it ranked 8th out of 57 species and cultivars in a public poll organized by the Center for Applied Nursery Research (CANR) at the University of Georgia, US. In the UK, B. crispa was accorded the Royal Horticultural Society's Award of Merit in 1961. However, the species is not entirely cold-hardy, and thus its popularity is not as ubiquitous as it might otherwise be.
Eupatorium japonicum, known as fragrant eupatorium in English and 白头婆 bai tou po, in Chinese, is a herbaceous plant species in the family Asteraceae. It is native to China, Japan and Korea.
Prunus sibirica, commonly known as Siberian apricot, is a species of shrub or small tree native to northern China, Korea, Mongolia, and eastern Siberia. It is classified in the rose family, Rosaceae, and is one of several species whose fruit are called apricot, although this species is rarely cultivated for its fruit. The species was named by Carl Linnaeus in 1753.
Iris tenuifolia is a beardless iris in the genus Iris, in the subgenus Limniris and in the series Tenuifoliae of the genus. It is a rhizomatous herbaceous perennial, from a wide region over central Asia, including Afghanistan, Pakistan, ; Kazakhstan, Uzbekistan and Mongolia and in China. It has long greyish-green leaves, short stem and pale violet, lilac, pale blue, or purple flowers.
Syringa tomentella is a species in the genus Syringa, in the family Oleaceae.
Iris bloudowii is a species in the genus Iris, it is also in the subgenus of Iris and in the Psammiris section. It is a rhizomatous perennial, from Russia, Siberia, Kazakhstan, Mongolia and China, with sickle-shaped leaves, slender stem and 2 bright or pale yellow flowers. It is cultivated as an ornamental plant in temperate regions.
Iris curvifolia is a plant species in the genus Iris, it is also in the subgenus of Iris, and in the Psammiris section. It is a rhizomatous perennial, from China. It has sickle-shaped long leaves, short stem and yellow or bright yellow flowers. It is cultivated as an ornamental plant in temperate regions.
Iris ivanovae is a plant species in the genus Iris, it is also in the subgenus Iris and in the section Pseudoregelia. It is a rhizomatous perennial, from eastern Russia, China, and Mongolia.
The Peltaspermales are an extinct order of seed plants, often considered "seed ferns". They span from the Late Carboniferous to the Early Jurassic. It includes at least one valid family, Peltaspermaceae, which spans from the Permian to Early Jurassic, which is typified by a group of plants with Lepidopteris leaves, Antevsia pollen-organs, and Peltaspermum ovulate organs, though the family now also includes other genera like Peltaspermopsis, Meyenopteris and Scytophyllum. Along with these, two informal groups of uncertain taxonomic affinities exist, each centered around a specific genus ; Supaia and Comia, known from the Early Permian of the Northern Hemisphere, especially of North America. Both the "Comioids" and the "Supaioids" are associated with the peltaspermacean ovulate organ Autunia. The Late Triassic-Middle Jurassic genus Pachydermophyllum may also have affinities to the peltasperms.
Baiera is a genus of prehistoric gymnosperms in the order Ginkgoales. It is one of the oldest fossil foliage types of Ginkgoales, and is related to the genera Ginkgo and Ginkgoites. Fossils of Baiera are found worldwide, and have been known from the Permian to the Cretaceous.
Salix daliensis is a shrub from the genus of willows (Salix) with mostly 5 to 6 centimeters long leaf blades. The natural range of the species is in China.
Pterophyllum is an extinct form genus of leaves known from the Carnian to the Maastrichtian, belonging to the Bennettitales. It contains more than 50 species, and is mainly found in Eurasia and North America.
Comptonia columbiana is an extinct species of sweet fern in the flowering plant family Myricaceae. The species is known from fossil leaves found in the early Eocene deposits of central to southern British Columbia, Canada, plus northern Washington state, United States, and, tentatively, the late Eocene of Southern Idaho and Earliest Oligocene of Oregon, United States.
This paleobotany list records new fossil plant taxa that were to be described during the year 2022, as well as notes other significant paleobotany discoveries and events which occurred during 2022.
Eoginkgoites is an extinct form genus of bennettitalean leaves from the Late Triassic of North America. Despite its palmate (hand-shaped) appearance similar to some early ginkgo species, it belongs to a different gymnosperm order, the Bennettitales. The leaf is deeply segmented into five to seven narrow, club-shaped lobes which twist around a very short rhachis. This leads to an overall fan-shaped leaf situated at the end of a long petiole. The leaf has paracytic stomata and veins which strongly branch and lead to a marginal vein at the edge of each leaflet. These structural traits are all shared with benettitaleans. Williamsonia carolinensis, an ovule-bearing bennettitalean cone, has been found closely associated with Eoginkgoites leaves, seemingly confirming its benettitalean identity.
Umaltolepis is an extinct genus of seed plant, known from the Early Jurassic to Early Cretaceous of Asia. Within the form classification system used within paleobotany, it refers to the seed-bearing reproductive structures, which grew on woody plants with strap-shaped Ginkgo-like leaves assigned to the genus Pseudotorellia.
