Joseph Friedrich Nicolaus Bornmüller
Joseph Friedrich Nicolaus Bornmüller (February 6, 1862 – December 19, 1948) was a German botanist born in Hildburghausen, Thuringia. Biography He studied horticulture in Potsdam, and in 1886 traveled to the Balkans and Greece on his first botanical expedition. In 1887-88 he worked at the botanical garden in Belgrade, and during his subsequent career conducted botanical studies widely throughout the Middle East, Asia Minor and North Africa. In his research, he also visited Greece, Madeira and the Canary Islands. In 1903 he succeeded Heinrich Carl Haussknecht (1838–1903) as curator of the "Haussknecht Herbarium" at Weimar, a position he maintained until 1938. In 1918 he was awarded an honorary professorship from the University of Jena. Among Bornmüller's many publications was a treatise on Macedonian flora titled ''Beiträge zur Flora Mazedoniens'' (1925–1928).

Rhamnaceae
The Rhamnaceae are a large family of flowering plants, mostly trees, shrubs, and some vines, commonly called the buckthorn family. Rhamnaceae is included in the order Rosales. The family contains about 55 genera and 950 species. The Rhamnaceae have a worldwide distribution, but are more common in the subtropical and tropical regions. The earliest fossil evidence of Rhamnaceae is from the Late Cretaceous. Fossil flowers have been collected from the Upper Cretaceous of Mexico and the Paleocene of Argentina. Leaves of family Rhamnaceae members are simple, i.e., the leaf blades are not divided into smaller leaflets.Flowering Plants of the Santa Monica Mountains, Nancy Dale, 2nd Ed. 2000, p. 166 Leaves can be either alternate or opposite. Stipules are present. These leaves are modified into spines in many genera, in some (e.g. ''Paliurus spina-christi'' and '' Colletia cruciata'') spectacularly so. ''Colletia'' stands out by having two axillary buds instead of one, one developing int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhamnus (plant)
''Rhamnus'' is a genus of about 110 accepted species of shrubs or small trees, commonly known as buckthorns, in the family Rhamnaceae. Its species range from tall (rarely to ) and are native mainly in east Asia and North America, but found throughout the temperate and subtropical Northern Hemisphere, and also more locally in the subtropical Southern Hemisphere in parts of Africa and South America. One species, the common buckthorn (''Rhamnus cathartica''), is able to flourish as an invasive plant in parts of Canada and the U.S., where it has become naturalized. Both deciduous and evergreen species occur. The leaves are simple, long, and arranged alternately, in opposite pairs, or almost paired (subopposite). One distinctive character of many buckthorns is the way the veination curves upward towards the tip of the leaf. The plant bears fruits which are black or red berry-like drupes. The name is due to the woody spine on the end of each twig in many species. One species is kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
