Graellsia (plant)
''Graellsia'' is a genus of small perennial plant, perennial sub-caespitose herbs in the family Brassicaceae. Most of the species are found in Iran and Afghanistan, with one occurring in Turkey, and one in the High Atlas of Morocco. They are typically found in shady crevices of calcareous rocks at altitudes of . The genus was erected in 1842 by Pierre Edmond Boissier, commemorating the Spanish zoologist Mariano de la Paz Graells y de la Agüera. It initially contained only ''Graellsia saxifragifolia'', which had previously been placed in ''Cochlearia''. New species were gradually added, and ''Graellsia hederifolia, G. hederifolia'' was moved to ''Graellsia'', having previously been the only species in ''Draba'' sect. ''Helicodraba''. Subsequent investigations using molecular phylogenetics have questioned the grouping of ''G. hederifolia'' and ''G. saxifraga'', and ''G. hederifolia'' may need to be restored to the genus ''Draba''. It contains the following species: *''Graellsia ch ...

Pierre Edmond Boissier
Pierre Edmond Boissier (25 May 1810 Geneva – 25 September 1885 Valeyres-sous-Rances) was a Swiss prominent botanist, explorer and mathematician. He was the son of Jacques Boissier (1784-1857) and Caroline Butini (1786-1836), daughter of Pierre Butini (1759-1838) a well-known physician and naturalist from Geneva. With his sister, Valérie Boissier (1813-1894), he received a strict education with lessons delivered in Italian and Latin. Edmond's interest in natural history stemmed from holidays in the company of his mother and his grandfather, Pierre Butini at Valeyres-sous-Rances. His hikes in the Jura and the Alps laid the foundation of his zest for later exploration and adventure. He attended a course at the Academy of Geneva given by Augustin Pyramus de Candolle. Edmond Boissier collected extensively in Europe, North Africa and western Asia, on occasion accompanied by his daughter, Caroline Barbey-Boissier (1847-1918) and her husband, William Barbey (1842-1914), who collect ...

Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree. History The theoretical frame ...
