Ulmaceae
The Ulmaceae () are a family of flowering plants that includes the elms (genus ''Ulmus''), and the zelkovas (genus ''Zelkova''). Members of the family are widely distributed throughout the north temperate zone, and have a scattered distribution elsewhere except for Australasia. The family was formerly sometimes treated to include the 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 mucilaginous substances in leaf and bark tissue. 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. The flowers are small and either bisexual or unise ...

Zelkova
''Zelkova'' (from 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 (''Z. sicula'') to large trees up to tall (''Z. carpinifolia''). The bark is smooth, dark brown. Unlike the elms, the branchlets are never corky or winged. The leaves are alternate, with serrated margins, and (unlike the related elms) a symmetrical base to the leaf blade. The leaves are in two distinct rows; they have pinnate 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 polygamous. Staminate flowers are clustered in the lower leaf axils of young branchlets; the perianth is campanulate, with four to six (to seven) lobes, and the stamens are short. Pistillate and hermaphrodite flowers are solita ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ulmus
Elms are deciduous and semi-deciduous trees comprising the flowering plant genus ''Ulmus'' in the plant family Ulmaceae. They are distributed over most of the Northern Hemisphere, inhabiting the temperate and tropical-montane regions of North America and Eurasia, presently ranging southward in the Middle East to Lebanon and Israel,Flora of Israel OnlineUlmus minor Mill. , Flora of Israel Online accessdate: July 28, 2020 and across the Equator in the Far East into Indonesia.Fu, L., Xin, Y. & Whittemore, A.

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 species, ''Planera aquatica'', the planertree or water elm. Found in the southeastern United States, it is a small deciduous tree 10–15 m tall, closely related to the elms but with a softly, prickly nut 10–15 mm 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 (biology), family of flowering plants, known as the hemp family. As now Circumscription (taxonomy), 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. ''Hu ...

Celtis
''Celtis'' is a genus of about 60–70 species of deciduous trees, commonly known as hackberries or nettle trees, widespread in warm temperate regions of the Northern Hemisphere. The genus is part of the extended hemp family (Cannabaceae). Description ''Celtis'' species are generally medium-sized trees, reaching tall, rarely up to tall. The leaves are alternate, simple, long, 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 fuzzy. 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. Taxonomy Previously included either in the elm family (Ulmaceae) or a separate family, Celtidaceae, the APG III system places ''Celtis'' ...

Fruit
In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering. Fruits are the means by which flowering plants (also known as angiosperms) disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; in fact, humans and many 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 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" also i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Samara (fruit)
A samara (, ) is a winged achene, a type of fruit in which a flattened wing of fibrous, papery tissue develops from the ovary wall. A samara is a simple dry fruit, and is indehiscent (not opening along a seam). The shape of a samara enables the wind to carry the seed farther away from the tree than regular seeds would go, and is thus a form of anemochory. In some cases the seed is in the centre of the wing, as in the elms (genus ''Ulmus''), the hoptree (''Ptelea trifoliata''), and the bushwillows (genus ''Combretum''). In other cases the seed is on one side, with the wing extending to the other side, making the seed autorotate as it falls, as in the maples (genus '' Acer'') and ash trees (genus ''Fraxinus''). There are also single-wing samara such as mahogany (genus Swietenia) which have a shape that enables fluttering. Some species that normally produce paired samaras, such as ''Acer pseudoplatanus'', can also produce them in groups of three or four. File:TripleSycamoreS ...
