context_page_description: The Platanaceae are a family of flowering plants belonging to the order Proteales. This family has been recognized by almost all taxonomists, and is sometimes called the "plane-tree family". The family consists of only a single extant genus Platanus, with eight known species. The plants are tall trees, native to temperate and subtropical regions of the Northern Hemisphere. The hybrid London plane is widely planted in cities worldwide.
  The plane-tree is referenced in Pliny the Younger's letter to Domitius Apollinaris as part of his description of his Tuscan Villa located somewhere in Tuscany in the first century.
context_section_description: The London plane-tree or hybrid plane has long been considered a hybrid derived from the cross between P. occidentalis and P. orientalis, despite this its origin is not clear. Some experts think it originated in London and others in Spain or even in natural or cultivated hybrid form (or not) in Turkey. The question has not been investigated with modern molecular methods. As a consequence, even its nomenclature is hotly debated, to the extent that Anglo-Saxon authors deny the priority of the name used in Spain (following Maria da Luz de Oliveira Tavares Monteiro da Rocha Afonso, 1990, see References). The plant is not found in the wild, though it appears in a naturalized form along the banks of rivers and streams.
  Hybrid (?) Platanus × hispanica  Mill. ex Münchh., 1770 (= P. orientalis var. acerifolia Aiton, 1789; P. hybrida Brot., 1804; P. vulgaris Spach, 1841, nom. illeg.; P. × acerifolia.
  Other names proposed for hybrids that are probably synonymous with the above, which is the only name in English, and which represent smaller minorities are:
  Hybrid Platanus × cantabrigensis A.Henry, 1919
  Hybrid Platanus × parviloba A.Henry, 1919
  The references consulted do not agree as to whether the fruit is a nucule or achene, the difference between the two ultimately depends on the size of the pericarp and the extent of its lignification. The fruit is dry, indehiscent, monocarpelar and monospermatic.
