Vauquelinia
''Vauquelinia'', commonly known as the rosewoods, is a genus of the rose family, Rosaceae. It consists of two species of shrubs found in the southwestern United States and northwestern Mexico. The genus was named for French chemist Louis Nicolas Vauquelin (1763-1829). The nectar provided by these plants is commonly fed on by wasps such as ''Polistes instabilis''. '' V. californica'' is of some interest as an ornamental. Taxonomy ''Vauquelinia'', along with ''Lindleya'' and ''Kageneckia'' were formerly placed in family Quillajaceae, and have dry dehiscent fruit. Unlike the pome-fruited members of tribe Maleae within the Rosaceae, which share a base chromosome number of 17 with ''Lindleya'' and ''Kageneckia'', ''Vauquelinia'' has a base chromosome number of 15.

Vauquelinia Californica
''Vauquelinia californica'', commonly known as Arizona rosewood, is an evergreen species of shrub or tree, in the rose family, Rosaceae. The dark brown wood streaked with red, and is hard and very heavy, a beautiful 'rosewood.' It has dense white blossoms in early Spring. Distribution The plant is native to the Southwestern United States in Arizona and southwestern New Mexico in Madrean Sky Islands habitats, the Peninsular Ranges in Baja California and northern Baja California Sur, and Sonora in Northwestern Mexico. Prehistoric From pollen core data, a portion of the Prehistory, prehistoric distribution of ''Vauquelinia californica'' has been mapped. For example, in the Wisconsin glaciation, Late Wisconsin period, this species occurred at lower elevations within the Waterman Mountains in southern Arizona than currently found. Cultivation ''Vauquelinia californica'' is cultivated as an ornamental plant. It is used as a drought-tolerant shrub, hedge, or small tree. When trained a ...

Louis Nicolas Vauquelin
Prof. Louis Nicolas Vauquelin Royal Society of London, FRS(For) HFRSE (16 May 1763 – 14 November 1829) was a French pharmacist and chemist. He was the discoverer of both chromium and beryllium. Early life Vauquelin was born at Saint-André-d'Hébertot in Normandy, France, the son of Nicolas Vauquelin, an estate manager, and his wife, Catherine Le Charterier. His first acquaintance with chemistry was gained as laboratory assistant to an apothecary in Rouen (1777–1779), and after various vicissitudes he obtained an introduction to Antoine François, comte de Fourcroy, A. F. Fourcroy, in whose laboratory he was an assistant from 1783 to 1791. Moving to Paris, he became a laboratory assistant at the Jardin du Roi and was befriended by a professor of chemistry. In 1791 he was made a member of the Academy of Sciences and from that time he helped to edit the journal ''Annales de Chimie'' ''(Chemical annals)'', although he left the country for a while during the height of the French ...

Aimé Bonpland
Aimé Jacques Alexandre Bonpland (; 22 August 1773 – 11 May 1858) was a French explorer and botanist who traveled with Alexander von Humboldt in Latin America from 1799 to 1804. He co-authored volumes of the scientific results of their expedition. Biography Bonpland was born as Aimé Jacques Alexandre Goujaud in La Rochelle, France, on 22, 28,. or 29 August 1773. His father was a physician and, around 1790, he joined his brother Michael in Paris, where they both studied medicine. From 1791, they attended courses given at Paris's Botanical Museum of Natural History. Their teachers included Jean-Baptiste Lamarck, Antoine Laurent de Jussieu, and René Louiche Desfontaines; Aimé further studied under Jean-Nicolas Corvisart and may have attended classes given by Pierre-Joseph Desault at the Hôtel-Dieu. During this period, Aimé also befriended his fellow student, Xavier Bichat. Amid the turmoil of the French Revolution and Revolutionary Wars, Bonpland served as a surge ...

Pome
In botany, a pome is a type of fruit produced by flowering plants in the subtribe Malinae of the family Rosaceae. Well-known pomes include the apple, pear, and quince. Etymology The word ''pome'' entered English in the late 14th century, and referred to an apple or an apple-shaped object. It derived from the Old French word for "apple": (12th century; modern French is ), which in turn derived from the Late Latin or Vulgar Latin word "apple", originally the plural of Latin "fruit", later "apple". Morphology A pome is an accessory fruit composed of one or more carpels surrounded by accessory tissue. The accessory tissue is interpreted by some specialists as an extension of the receptacle and is then referred to as "fruit cortex",Esau, K. 1977. ''Anatomy of seed plants''. John Wiley and Sons, New York. and by others as a fused hypanthium (floral cup). It is the most edible part of this fruit. The carpels of a pome are fused within the "core".

Dehiscence (botany)
Dehiscence is the splitting of a mature plant structure along a built-in line of weakness to release its contents. This is common among fruits, anthers and sporangia. Sometimes this involves the complete detachment of a part; structures that open in this way are said to be dehiscent. Structures that do not open in this way are called indehiscent, and rely on other mechanisms such as decay or predation to release the contents. A similar process to dehiscence occurs in some flower buds (e.g., ''Platycodon'', ''Fuchsia''), but this is rarely referred to as dehiscence unless wikt:circumscissile, circumscissile dehiscence is involved; anthesis is the usual term for the opening of flowers. Dehiscence may or may not involve the loss of a structure through the process of abscission. The lost structures are said to be wikt:caducous, caducous. Association with crop breeding Manipulation of dehiscence can improve crop yield since a Trait (biological), trait that causes seed dispersal i ...

Quillaja
''Quillaja'' is a genus of flowering plants, the only extant genus in the family Quillajaceae with two or three known species. It was once thought to be in the rose family, Rosaceae, but recent research shows it belongs in its own family. The inner bark of the soap bark tree ('' Q. saponaria'') contains saponin, which is a natural soap. Members of this genus are tree In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves.
