Banksieaeformis
''Banksieaeformis'' is a genus that encompasses plant species only known from fossil leaves that can be attributed to the Proteaceae tribe Banksieae, but cannot be attributed to an extant (living) genus. Unlike those classified in the related genus ''Banksieaephyllum'', the leaves do not have their cuticular architecture preserved. The genus was defined by botanists Bob Hill and David Christophel in 1988 to distinguish banksia-like leaves that had been organically preserved from those that had not. The two authors designated ''Banksieaeformis decurrens'' as the type species. Recovered from middle Eocene deposits at Maslin Bay in South Australia, it is known from a single leaf, 7 cm long and 1 cm wide. The leaf has entire margins in its basal half and pinnate lobes pointed apically in its apical half, which resembles the leaves of the fossil species ''Banksieaephyllum cuneatum'' and ''Banksieaephyllum incisum, B. incisum'', as well as the living species ''Banksia grandis' ...

Banksieaephyllum Fastigiatum
''Banksieaephyllum'' is a plant genus that encompasses organically preserved fossil leaves that can be attributed to the Proteaceae tribe Banksieae, but cannot be attributed to a genus. Before 1950, many fossil leaves were attributed to the genera ''Banksia'' and ''Dryandra''. In most cases, leaves with triangular lobes were associated with ''Dryandra'', and leaves with serration were associated with ''Banksia''. In 1950, Isabel Cookson and Suzanne Duigan showed this policy to be flawed, by demonstrating that the leaves of the two genera cannot be reliably distinguished. Since these two genera then comprised tribe Banksieae, Cookson and Duigan erected ''Banksieaephyllum'' to contain such leaves. Since then, ''Banksia'' and ''Dryandra'' have been further grouped into subtribe Banksiinae, and another subtribe, Musgraveinae, erected to contain two new genera. Interpretations of ''Banksieaephyllum'' are now no longer consistent. Some botanists continue to hold that ''Banksieaephyllu ...

Banksieae
The Grevilleoideae are a subfamily of the plant family Proteaceae. Mainly restricted to the Southern Hemisphere, it contains around 46 genus, genera and about 950 species. Genera include ''Banksia'', ''Grevillea'', and ''Macadamia''. Description The Grevilleoideae grow as trees, shrubs, or subshrubs. They are highly variable, making a simple, diagnostic identification key for the subfamily essentially impossible to provide. One common and fairly diagnostic characteristic is the occurrence of flowers in pairs that share a common bract. However, a few Grevilleoideae taxa do not have this property, having solitary flowers or inflorescences of unpaired flowers. In most taxa, the flowers occur in densely packed heads or spikes, and the fruit is a follicle (fruit), follicle. Distribution and habitat Grevilleoideae are mainly a Southern Hemisphere family. The main centre of diversity is Australia, with around 700 of 950 species occurring there, and South America also contains taxa. How ...

Eocene Plants
The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in comparison with the more common isotope 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and end of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
