Per Karl Hjalmar Dusén
Per Karl Hjalmar Dusén (1855–1926) was a Swedish civil engineer, botanist and explorer. As a botanist his interests included pteridology, bryology, and paleobotany. He made botanical expeditions to Africa, Greenland, and South America. During his expeditions to Greenland, he visited Disko Island to catalogue the variety of flowering plants, horsetails and ferns. Between 1890 and 1892, Dusén collected nearly 560 leaf fossils preserved in basalt in the vicinity of Mount Cameroon on the west coast of Cameroon. Later, these fossils were studied by the German paleobotanist Paul J. Menzel (1864–1927). His botanical specimens are at the New York Botanical Garden, being obtained when they acquired the herbarium of Princeton University in 1945. Honours More than 200 species were named in his honour, including: * (Acanthaceae) '' Acanthus dusenii'' C.B.Clarke * (Acanthaceae) '' Justicia dusenii'' (Lindau) Wassh. & L.B.Sm. in Reitz * (Anacardiaceae) '' Trichoscypha dusenii'' Engl. * ...

Eupatorieae
Eupatorieae is a tribe of over 2000D.J.N.Hind & H.E.Robinson. 2007. Tribe Eupatorieae In: ''The Families and Genera of Vascular Plants'' vol.VIII.

Most of the species are native to tropical, subtropical, and warm temperate areas of the Americas, but some are found elsewhere.Turner,B.L.(1997). Eupatorieae.

Endemic Flora Of Brazil
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of The Atlantic Forest
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
