Iguanurinae is a palm tree subtribe in the tribe Areceae. [1] [2] It is not recognized in recent classifications.
The Noctuidae, commonly known as owlet moths, cutworms or armyworms, are a family of moths. They are considered the most controversial family in the superfamily Noctuoidea because many of the clades are constantly changing, along with the other families of the Noctuoidea. It was considered the largest family in Lepidoptera for a long time, but after regrouping Lymantriinae, Catocalinae and Calpinae within the family Erebidae, the latter holds this title now. Currently, Noctuidae is the second largest family in Noctuoidea, with about 1,089 genera and 11,772 species. This classification is still contingent, as more changes continue to appear between Noctuidae and Erebidae.
Salviniaceae, is a family of heterosporous ferns in the order Salviniales. The Salviniaceae contain the two genera Azolla and Salvinia, with about 20 known species in total. The oldest records of the family date to the Late Cretaceous. Azolla was previously placed in its own family, Azollaceae, but research has shown Azolla and Salvinia to be sister genera with the likely phylogenic relationship shown in the following diagram.
Glossopteris is the largest and best-known genus of the extinct Permian order of seed plants known as Glossopteridales. The genus Glossopteris refers only to leaves, within a framework of form genera used in paleobotany. Species of Glossopteris were the dominant trees of the middle to high-latitude lowland vegetation across the supercontinent Gondwana during the Permian Period. Glossopteris fossils were critical in recognizing former connections between the various fragments of Gondwana: South America, Africa, India, Australia, New Zealand, and Antarctica.
Chaetocarpeae is a tribe of plant of the family Euphorbiaceae. It comprises 2 genera.
Pycnocomeae is a tribe of plant of the family Euphorbiaceae. It comprises 2 subtribes and 7 genera.
Ctenolophon is the only genus in the flowering plant family Ctenolophonaceae. It has two recognized species:
Gonyaulax is a genus of dinoflagellates with the type species Gonyaulax spinifera Diesing. Gonyaulax belongs to red dinoflagellates and commonly causes red tides. It can produce yesotoxins: for example, strains of Gonyaulax spinifera from New Zeland are yessotoxin producers.
Ginkgo yimaensis is an extinct ginkgo species in the family Ginkgoaceae. It is a gymnosperm, first described by Zhou and Zhang.
Nilssonia is a genus of fossil foliage traditionally assigned to the Cycadophyta either in Cycadales or their own order Nilssoniales, though the relationships of this genus with the Cycadales have been put into question on chemical grounds.
The Price Formation is a geologic formation in Virginia. It preserves fossils dating back to the Carboniferous period.
The Battery Point Formation is a geologic formation in Quebec. It preserves fossils dating back to the early Emsian to early Eifelian the lower Devonian period.
A glacial refugium is a geographic region which made possible the survival of flora and fauna during ice ages and allowed for post-glacial re-colonization. Different types of glacial refugia can be distinguished, namely nunatak, peripheral, and lowland. Glacial refugia have been suggested as a major cause of floral and faunal distribution patterns in both temperate and tropical latitudes. With respect to disjunct populations of modern-day species, especially in birds, doubt has been cast on the validity of such inferences, as much of the differentiation between populations observed today may have occurred before or after their restriction to refugia. In contrast, isolated geographic locales that host one or more critically endangered species are generally uncontested as bona fide glacial refugia.
Borasseae is a tribe in the palm subfamily Coryphoideae. The tribe ranges from southern Africa and Madagascar north through the Arabian Peninsula to India, Indochina, Indonesia and New Guinea. Several genera are restricted to islands in the Indian Ocean. The two largest genera, Hyphaene and Borassus, are also the most widespread.
Trachycarpeae is a tribe of palms in subfamily Coryphoideae of the plant family Arecaceae. It has the widest distribution of any tribe in Coryphoideae and is found on all continents, though the greatest concentration of species is in Southeast Asia. Trachycarpeae includes palms from both tropical and subtropical zones; the northernmost naturally-occurring palm is a member of this tribe. Several genera can be found in cultivation in temperate areas, for example species of Trachycarpus, Chamaerops, Rhapidophyllum and Washingtonia.
The Tupuangi Formation is a geological formation in New Zealand, only exposed on Pitt Island in the Chatham Islands. It is the oldest exposed sedimentary unit within the archipelago. It was deposited in terrestrial deltaic to paralic conditions during the Cenomanian to Turonian ages of the Late Cretaceous. During this time period the Chatham Islands were attached to Antarctica within the Antarctic Circle, at approximately 70° to 80° south.
The Waterloo Farm lagerstätte is a Famennian lagerstätte in South Africa that constitutes the only known record of a near-polar Devonian coastal ecosystem.
Sergio Archangelsky was an Argentine paleobotanist and palynologist. He was a pioneer of modern paleobotany in Argentina, as well as of cuticular morphology and ultrastructure. He was also a corresponding member of the Argentine Academy of Science.
Otozamites is an extinct form genus of leaves belonging to the Bennettitales.
Nilssoniopteris is an extinct form genus of leaves belonging to the Bennettitales. Leaves are slender and often entire-margined (smooth-edged), though some species have dissected leaves with numerous small segments extending down to the rachis of the leaf. Nilssoniopteris-like leaves are distinguished by their syndetocheilic stomata, indicating bennettitalean affinities. Similar "taeniopterid" leaves are placed in the genus Nilssonia if their stomata are instead haplocheilic, or Taeniopteris if the cuticle is not preserved. Leaves of Nilssoniopteris vittata from the Middle Jurassic of England are associated with bisexual Williamsoniella reproductive structures.
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.
