Isoetes Malinverniana
''Isoetes malinverniana'', the Piedmont quillwort, is a species of quillwort. It is critically endangered. Distribution It is found in Italy. There is a breeding program to aid conservation. Taxonomy It was named by Vincenzo de Cesati and Giuseppe De Notaris Giuseppe De Notaris (18 April 1805, Milan – 22 January 1877) was an Italian botanist generally known for his work with cryptogams native to Italy. He studied medicine at the University of Pavia, obtaining his medical degree in 1830. Having deve ..., in ''Index Seminum'' (GE, Genuensis) 1858: 36 in 1858.

Vincenzo De Cesati
Vincenzo de Cesati (1806–1883) was an Italian botanist from Milan. He studied natural history and law at the University of Vienna, and afterwards worked as a volunteer at the Collegium Nacionale de Vercelli. From 1868 to 1883 he was director of the botanical garden at Naples. The majority of his plant collection is now preserved at the botanical institute of the University of Rome. The plant genus '' Cesatia'' from the family Apiaceae is named after him. Works With Giovanni Passerini (1816-1893) and Giuseppe Gibelli (1831-1898), he was author of "''Compendio della flora italiana''", a compendium of Italian flora. HathiTrust Digital Library Other works by Cesati include: * ''Stirpes Italicae: iconografia universale delle piante italiane'' (Pyrole, Milan, 1840) * ''Saggio di una bibliograf ...

Giuseppe De Notaris
Giuseppe De Notaris (18 April 1805, Milan – 22 January 1877) was an Italian botanist generally known for his work with cryptogams native to Italy. He studied medicine at the University of Pavia, obtaining his medical degree in 1830. Having developed an interest in botany, by 1832 he had abandoned the field of medicine. In 1836 he accepted an assignment at the botanical garden in Turin, and a few years later, was named professor of botany and director of the botanical garden at the University of Genoa (1839). In 1872 he was appointed chair of botany at the University of Rome. In the field of mycology, he proposed the fungi family Hypocreaceae (1845). With Antonio Bey Figari (1804-1870), he described numerous species from the family Poaceae. With Figari, he was the binomial co-author of the grass genus ''Schistachne'' (synonym ''Stipagrostis''). Organisms with the specific epithet of ''notarisiana'' commemorate his name. Selected works * Muscologiae italicae spicilegium, 1837 ...

List Of Critically Endangered Plants
As of September 2016, the International Union for Conservation of Nature (IUCN) lists 2493 critically endangered plant species, including 145 which are tagged as ''possibly extinct'' or ''possibly extinct in the wild''. 11% of all evaluated plant species are listed as critically endangered. The IUCN also lists 89 subspecies and 70 varieties as critically endangered. Additionally 1674 plant species (7.6% of those evaluated) are listed as ''data deficient'', meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. While the category of ''data deficient'' indicates that no assessment of extinction risk has been made for the taxa, the IUCN notes that it may be appropriate to give them "the same degree of attention as threatened taxa, at least until their status can be assessed."

Isoetes
''Isoetes'', commonly known as the quillworts, is the only extant genus of plants in the family Isoetaceae, which is in the class of lycopods. There are currently 192 recognized species, with a cosmopolitan distribution but with the individual species often scarce to rare. Some botanists split the genus, separating two South American species into the genus ''Stylites'', although molecular data place these species among other species of ''Isoetes'', so that ''Stylites'' does not warrant taxonomic recognition. Species of ''Isoetes'' virtually identical to modern forms have existed since the Jurassic epoch. The name of the genus may also be spelled ''Isoëtes''. The diaeresis (two dots over the e) indicates that the o and the e are to be pronounced in two distinct syllables. Including this in print is optional; either spelling (''Isoetes'' or ''Isoëtes'') is correct. Description Quillworts are mostly aquatic or semi-aquatic in clear ponds and slow-moving streams, though several ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
