Ulmaceae
The Ulmaceae () are a family (biology), family of flowering plants that includes the elms (genus ''Ulmus''), and the zelkovas (genus ''Zelkova''). Members of the family are widely distributed throughout the Temperate, north temperate zone, and have a scattered distribution elsewhere except for Australasia. The family was formerly sometimes treated to include the Celtis, hackberries, (''Celtis'' and allies), but an analysis by the Angiosperm Phylogeny Group suggests that these genera are better placed in the related family Cannabaceae. It generally is considered to include ca 7 genera and about 45 species. Some classifications also include the genus ''Ampelocera''. Description The family is a group of evergreen or deciduous trees and shrubs with mucilage, mucilaginous substances in leaf and bark tissue. Leaf, Leaves are usually alternate on the stems. The leaf blades are simple (not compound), with entire (smooth) or variously toothed margins, and often have an asymmetrical base. ...

Zelkova
''Zelkova'' (from the Georgian language, Georgian ''dzelkva'', 'stone pillar') is a genus of six species of deciduous trees in the elm family Ulmaceae, native to southern Europe, and southwest and eastern Asia. They vary in size from shrubs (''Zelkova sicula, Z. sicula'') to large trees up to tall (''Zelkova carpinifolia, Z. carpinifolia''). The bark is smooth, dark brown. Unlike the elms, the branchlets are never corky or winged. The leaf, leaves are alternate, with serration, serrated margins, and (unlike the related elms) a symmetrical base to the leaf blade. The leaves are in two distinct rows; they have pinnation, pinnate Venation (botany) , venation and each vein extends to the leaf margin, where it terminates in a tooth. There are two stipules at each node, though these are caducous (shed early), leaving a pair of scars at the leaf base. ''Zelkova'' is Plant reproductive morphology, polygamous. Stamen, Staminate flowers are clustered in the lower leaf axils of young branch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ulmus
Elms are deciduous and semi-deciduous trees comprising the genus ''Ulmus'' in the family Ulmaceae.

Elms are components of many kinds of natural forests. Moreover, during the 19th and early 20th centuries, many species and cultivars were also planted as ornamental street, garden, and park trees in Europe, North America, and parts of the Southern Hemisphere, notably Australasia.

Planera
''Planera'' is a genus of flowering plants with a single living species, '' Planera aquatica'', the planertree or water elm. The genus has an extensive fossil record dating back to the Cretaceous and spanning the northern hemisphere, with a few southern hemisphere records as well. The living species is found in the southeastern United States, it is a small deciduous tree tall, closely related to the elms but with a softly, prickly nut diameter, instead of a winged seed. It grows, as the name suggests, on wet sites. Despite its common English name, this species is not a true elm, although it is a close relative of the elms (species of the genus ''Ulmus''). It is also subject to Dutch elm disease, a disease which affects only members of the Ulmaceae. It is native to most of the southeast United States. It is hardy down to Zone 7.

Cannabaceae
Cannabaceae is a small family of flowering plants, known as the hemp family. As now circumscribed, the family includes about 170 species grouped in about 11 genera, including '' Cannabis'' (hemp), '' Humulus'' (hops) and '' Celtis'' (hackberries). ''Celtis'' is by far the largest genus, containing about 100 species.Stevens, P.F. (2001 onwards"Cannabaceae" ''Angiosperm Phylogeny Website'', retrieved 2014-02-25 Cannabaceae is a member of the Rosales. Members of the family are erect or climbing plants with petalless flowers and dry, one-seeded fruits. Hemp (''Cannabis'') and hop (''Humulus'') are the most economically important species. Other than a shared evolutionary origin, members of the family have few common characteristics; some are trees (e.g. ''Celtis''), others are herbaceous plants (e.g. ''Cannabis''). Description Members of this family can be trees (e.g. '' Celtis''), erect herbs (e.g. '' Cannabis''), or twining herbs (e.g. '' Humulus''). Leaves are often more or l ...

Celtis
''Celtis'' is a genus of about 60–70 species of deciduous trees, commonly known as hackberries or nettle trees, in the hemp family Cannabaceae. It has a cosmopolitan distribution. Description ''Celtis'' species are generally medium-sized trees, reaching tall, rarely up to tall. The leaves are alternate, simple, long, Glossary of leaf morphology#ovate, ovate-acuminate, and evenly serrated margins. Diagnostically, ''Celtis'' can be very similar to trees in the Rosaceae and other rose motif families. Small flowers of this monoecious plant appear in early spring while the leaves are still developing. Male flowers are longer and hairy. Female flowers are greenish and more rounded. The fruit is a small drupe in diameter, edible in many species, with a dryish but sweet, sugary consistency, reminiscent of a date palm, date. Taxonomy Previously included either in the elm family (Ulmaceae) or a separate family, Celtidaceae, the APG III system places ''Celtis'' in an expanded hemp ...

American Journal Of Botany
The ''American Journal of Botany'' is a monthly peer-reviewed scientific journal which covers all aspects of plant biology. It has been published by the Botanical Society of America since 1914. The journal has an impact factor of 3.038, as of 2019. access is available through the publisher John Wiley & Sons ( Wiley). From 1951 to 1953, Oswald Tippo served as its editor; the current editor is Pamela Diggle. History In the early 20th century, the field of botany was rapidly expanding, but the publications in which botanists could publish remained limited and heavily backlogged. By 1905, it was estimated that 250,000 contributions were generated in 8 or 9 languages. At the 1911 annual meeting of the society in Washington D.C., it was noted that at least 300 pages of American botanical contributions were sent abroad for publication, with a backlog resulting in a one-year delay in publication. On 31 December 1907, the Botanical Society of America met in Chicago and formally recom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fruit
In botany, a fruit is the seed-bearing structure in flowering plants (angiosperms) that is formed from the ovary after flowering. Fruits are the means by which angiosperms disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and other animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; humans, and many other animals, have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language and culinary usage, ''fruit'' normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet (or sour) and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term ''fruit'' als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
