Bituminaria Morisiana
''Bituminaria morisiana'' is a perennial Mediterranean herb species in the genus ''Bituminaria''. Leaf, trifoliate with 3 linear, lanceolate, tomentose leaflets. White flowers in globose flowerheads. Fruit a tomentose legume. Flowers May–July. It is endemic to Sardinia where it is restricted to high mountain areas, such as Monte Albo and Monte Corrasi. The pterocarpan Pterocarpans are derivatives of isoflavonoids found in the family Fabaceae. It is a group of compounds which can be described as benzo-pyrano-furano-benzenes (i.e. 6''H''- enzofuro ,2-chromene skeleton) which can be formed by coupling of the B rin ...s bitucarpin A and B can be isolated from the aerial parts of ''B. morisiana'', erybraedin C from the leaves and morisianine is isolated from the seeds.A pterocarpan from the seeds of Bituminaria morisiana.

Alessandro "Sandro" Pignatti (born 28 September 1930) is an Italian botanist specialising in pteridophytes and spermatophytes. The Australian plant species '' Calectasia pignattiana'' was named after him. On 31 May 1991 Pignatti received an honorary doctorate An honorary degree is an academic degree for which a university (or other degree-awarding institution) has waived all of the usual requirements. It is also known by the Latin phrases ''honoris causa'' ("for the sake of the honour") or ''ad hon ... from the Faculty of Mathematics and Science at Uppsala University, Sweden.

Giardino Montano Linasia
The Giardino Montano Linasia (9,000 m2) is a nature preserve and botanical garden located at 720 meters altitude near Monte Linas in San Benedetto, Iglesias, Province of Carbonia-Iglesias, Sardinia, Italy. Opening days depend on the time of year; an admission fee is charged. The garden was established in 1989 by the Ente Foreste della Sardegna, and realized in 1992 in collaboration with the Istituto di Botanica dell' Università di Cagliari. It is organized into four major sections as follows: open areas; wooded areas; riparian vegetation; and endemic plant collection. Plants are labeled with scientific names and geographic origins. Species The garden contains roughly 60 species of endemic plants, as well as some 20 species of nonnative introductions. Endemic species include: * '' Allium parciflorum'' * '' Aquilegia nugorensis'' * ''Arenaria balearica'' * '' Armeria sulcitana'' * '' Arum pictum'' * ''Barbarea rupicola'' * '' Bellium bellidioides'' * '' Bellium crassifolium'' * ...

Pterocarpan
Pterocarpans are derivatives of isoflavonoids found in the family Fabaceae. It is a group of compounds which can be described as benzo-pyrano-furano-benzenes (i.e. 6''H''- enzofuro ,2-chromene skeleton) which can be formed by coupling of the B ring to the 4-one position. 2'-hydroxyisoflavone reductase is the enzyme responsible for the conversion in ''Cicer arietinum'' and glyceollin synthase for the production of glyceollins, phytoalexins in soybean. Known compounds * Bitucarpin A and B, isolated from the aerial parts of Mediterranean plants ''Bituminaria morisiana'' and ''Bituminaria bituminosa'' * Erybraedin A and B, isolated from the stems of ''Erythrina subumbrans'' and C, isolated from the leaves of ''Bituminaria morisiana'' * Erythrabyssin II, erystagallin A, erythrabissin-1, and erycristagallin isolated from the stems of ''Erythrina subumbrans'' * Glycinol, glyceollidin I and II, glyceollins (glyceollin I, II, III and IV), found in the soybean (''Glycin ...

Sardinia
Sardinia ( ; it, Sardegna, label=Italian, Corsican and Tabarchino ; sc, Sardigna , sdc, Sardhigna; french: Sardaigne; sdn, Saldigna; ca, Sardenya, label=Algherese and Catalan) is the second-largest island in the Mediterranean Sea, after Sicily, and one of the 20 regions of Italy. It is located west of the Italian Peninsula, north of Tunisia and immediately south of the French island of Corsica. It is one of the five Italian regions with some degree of domestic autonomy being granted by a special statute. Its official name, Autonomous Region of Sardinia, is bilingual in Italian and Sardinian: / . It is divided into four provinces and a metropolitan city. The capital of the region of Sardinia — and its largest city — is Cagliari. Sardinia's indigenous language and Algherese Catalan are referred to by both the regional and national law as two of Italy's twelve officially recognized linguistic minorities, albeit gravely endangered, while the regional law provides ...

Endemic
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Globose
A sphere () is a geometrical object that is a three-dimensional analogue to a two-dimensional circle. A sphere is the set of points that are all at the same distance from a given point in three-dimensional space.. That given point is the centre of the sphere, and is the sphere's radius. The earliest known mentions of spheres appear in the work of the ancient Greek mathematicians. The sphere is a fundamental object in many fields of mathematics. Spheres and nearly-spherical shapes also appear in nature and industry. Bubbles such as soap bubbles take a spherical shape in equilibrium. The Earth is often approximated as a sphere in geography, and the celestial sphere is an important concept in astronomy. Manufactured items including pressure vessels and most curved mirrors and lenses are based on spheres. Spheres roll smoothly in any direction, so most balls used in sports and toys are spherical, as are ball bearings. Basic terminology As mentioned earlier is the sphere's r ...
