Antoine Laurent Apollinaire Fée
Antoine Laurent Apollinaire Fée was a French botanist who was born in Ardentes, 7 November 1789, and died in Paris on 21 May 1874. He was the author of works on botany and mycology, practical and historical pharmacology, Darwinism, and his experiences in several regions of Europe. Biography After serving as a medical orderly during Napoleon's campaign in Spain, Fée established a pharmacy in Paris. He was schooled in the profession in Strasbourg, receiving his degree in 1815. He met the botanist Christiaan Hendrik Persoon in 1823, and came to be strongly influenced by him. Fée later became an instructor at teaching hospitals, firstly in Lille in 1825, then at Strasbourg in 1832. There he was promoted to M.D. and professor of botany. He also managed the botanical garden until Strasbourg was taken by the Prussians at the end of their war with France. Fée left and moved to Paris. In 1874 he was elected as the president of the Société botanique de France. He was a cryptog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyathea Corcovadensis
''Cyathea corcovadensis'' is a species of tree fern native to Paraguay and Serra do Mar in southern Brazil, where it grows in primary and secondary forest, as well as scrub, at an altitude of 250–2100 m. The erect trunk is short, usually about 30–60 cm tall. Fronds are bipinnate and 2.5 m or more in length. The rachis ranges in colour from brown to purplish and is covered with warts and scattered brown scales. Sori occur either between the fertile pinnule midvein and the edge of the lamina or just beside the midvein. They lack indusia. ''C. corcovadensis'' is a variable species, especially in terms of pinnule shape and degree of dissection. The specific epithet ''corcovadensis'' refers to Corcovado, the 704 m tall peak in central Rio de Janeiro Rio de Janeiro ( , , ; literally 'River of January'), or simply Rio, is the capital of the state of the same name, Brazil's third-most populous state, and the second-most populous city in Brazil, after São Paulo.

Cyatheales
The order Cyatheales, which includes most tree ferns, is a taxonomic order of the fern class, Polypodiopsida. No clear morphological features characterize all of the Cyatheales, but DNA sequence data indicate the order is monophyletic. Some species in the Cyatheales have tree-like growth forms from a vertical rhizome, others have shorter or horizontal expanding rhizomes. Some species have scales on the stems and leaves, while others have hairs. However, most plants in the Cyatheales are tree ferns and have trunk-like stems up to tall. It is unclear how many times the tree form has evolved and been lost in the order.Judd, W.S., C.S. Campbell, E.A. Kellogg, P.F. Stevens, and M.J. Donoghue (Eds.) 2008.

Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...
