Platanaceae
Platanaceae, the "plane-tree family", is a family of flowering plants in the order Proteales. 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. Description * Large, sympodial, deciduous tree, speckled bark that sheds in large irregular sheets, leaving a smooth surface that is mottled and pale, persistent bark at the base of the trunk, indumentum with large glandular hairs, multicellular and uniserrate or short with uniserrate ramification (in candelabrum), in stellate fascicles; glandular hairs with unicellular, globular capitulum, cuticular waxes without crystalloids, with rods and plates * Leaves generally with very variable shapes and nervation, simple, alternate, more or less distichous, isobilateral palmate with three to seven lobes (palmatifid to palmatisect) with who ...

Platanus Orientalis Tree, Thasos
''Platanus'' is a genus consisting of a small number of tree species native to the Northern Hemisphere. They are the sole living members of the family Platanaceae. All mature members of ''Platanus'' are tall, reaching in height. All except for '' P. kerrii'' are deciduous, and most are found in riparian or other wetland habitats in the wild, though proving drought-tolerant in cultivation. The hybrid London plane (''Platanus ''×'' acerifolia'') has proved particularly tolerant of urban conditions, and has been widely planted in London and elsewhere in the United Kingdom. They are often known in English as ''planes'' or ''plane trees''. A formerly used name that is now rare is ''plantain tree'' (not to be confused with other, unrelated, species with the name). Some North American species are called ''sycamores'' (especially ''Platanus occidentalis''), although the term is also used for several unrelated species of trees. The genus name ''Platanus'' comes from Ancient Gree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Macginitiea Gracilis SRIC SR 01-03-04 A Img1
''Macginitiea'' is an extinct genus in the family Platanaceae ranging from the Late Paleocene to Late Eocene of North America, known from the Clarno Formation of central Oregon. The genus is strictly used to describe leaves, but has been found in close association with other fossil platanoid organs, which collectively have been used for whole plant reconstructions. ''Macginitiea'' and its associated organs are important as together they comprise one of the most well-documented and ubiquitous fossil plants, particularly in the Paleogene of North America.Myers, J. A. (2003). Terrestrial Eocene-Oligocene Vegetation and Climate in the Pacific Northwest. ''From Greenhouse to Icehouse: The Marine Eocene-Oligocene Transition. Columbia University Press, New York'', 171-185. Because paleobotanical material is often found in disarticulation, different species names are often used to refer to different organs (e.g. leaves, fruits, wood) even if those organs might have belonged to the sam ...

Proteales
Proteales is an order of flowering plants consisting of three (or four) families. The Proteales have been recognized by almost all taxonomists. The representatives of the Proteales are very different from each other. The order contains plants that do not look alike at all. What they have in common is seeds with little or no endosperm. The ovules are often atropic. Families In the classification system of Dahlgren the Proteales were in the superorder Proteiflorae (also called Proteanae). The APG II system of 2003 also recognizes this order, and places it in the clade eudicots with this circumscription: * order Proteales :* family Nelumbonaceae :* family Proteaceae family Platanaceae">Platanaceae.html" ;"title=" family Platanaceae"> family Platanaceae with "+ ..." = optionally separate family (that may be split off from the preceding family). The APG III system of 2009 followed this same approach, but favored the narrower circumscription of the three families, firmly rec ...

Credneria
''Credneria'' is an extinct genus in the family or Platanaceae of broad-leaf trees similar to extinct ''Platanus'' species that appeared during the Cretaceous. The genus was first described by Zenker ( 1833) and has formerly been placed in the family Salicaceae rather than Platanaceae on occasion. ''Credneria'' leaves are preserved in sandstone and less often in siltstone. The leaves are typically obovate with a pinnate-actinodromous venation and distinct suprabasal veins. Species Known species are: * *''Credneria biloba'' *''Credneria bohemica'' *''Credneria comparabilis'' *''Credneria cuneifolia'' *''Credneria daturaefolia'' (Ward) *''Credneria denticulata'' *?''Credneria grewiopsoides'' *''Credneria integerrima'' *?''Credneria longifolia'' *''Credneria pachyphylla'' *''Credneria parva'' *''Credneria prophylloides'' ( Knowlton) *''Credneria pulchra'' *?''Credneria spatiosa'' *''Credneria subserrata'' (Hampe) *''Credneria subtriloba'' *''Credneria sudanense'' *''Credneria ...

Langeria
''Langeria'' is an extinct genus of flowering plants in the family Platanaceae containing the solitary species ''Langeria magnifica''. ''Langeria'' is known from fossil leaves found in the early Eocene deposits of northern Washington state, United States and similar aged formations in British Columbia, Canada. Distribution ''Langeria magnifica'' has been identified from a series of locations ranging from the Klondike Mountain Formation near Republic, Washington north. At least three locations in British Columbia have ''Langeria'' fossils, including the Coldwater Beds Quilchena locality near Merritt, the Tranquille Formations McAbee Fossil Beds near Kamloops, and the Chu Chua Formations Joseph Creek site near Chu Chua. Generally speaking, the age for the locations is Early Eocene, with the sites that have current uranium–lead or argon–argon radiometric dates being of Ypresian age, while the undated sites and sites with less current dating being possibly slightly you ...

Sapindopsis
''Sapindopsis'' ("''Sapindus''-like") is an extinct form genus for leaves of the Cretaceous Period, originally considered similar to soapberry. Associated reproductive structures now suggest it was more closely related to planes and sycamores of the family Platanaceae. Description In the form generic system of paleobotany ''Sapindopsis'' is used only for leaves, which are compound with three to six leaflets. Leaflets vary in distinctness or confluence with the midrib. The venation is pinnate, eucamptodromous to brochidodromus, with percurrent tertiary veins. Distribution and species ''Sapindopsis'' was geographically widespread from Asia to North America. Species include: *†'' Sapindopsis magnifolia'' (Fontaine) Dilcher and Basson 1990 ( type), from the Potomac Group, Early Cretaceous (Barremian) of Virginia, USA *†'' Sapindopsis anhouryi'' Dilcher and Basson 1990, from the Sannine Formation, mid-Cretaceous (Cenomanian) of Namoura, Lebanon. *†'' Sapindopsis asiatic ...

Tree
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typicall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
