Ulmus 'Night Rider'
''Ulmus'' 'Night Rider' is a hybrid elm cultivar raised from a crossing of 'Sapporo Autumn Gold' (female parent, a cross between Japanese elm and Siberian elm) and Japanese elm (male parent), by Rick Durand of the Prairie Shade Nursery in Portage la Prairie, Manitoba, c.2013. Notable for its high resistance to Dutch elm disease and for its purple fall leaves, it was released by Durand in 2020 at Bylands Nurseries, West Kelowna, British Columbia, as one of Bylands' research program elms. Durand was one of the partners who raised the Japanese elm cultivars 'Discovery' and 'Freedom'. Purple fall leaves are rare in elms, where yellow is the norm. Cultivars with burgundy fall leaves include 'Frontier' and 'Burgundy Glow' = . Description A fast growing elm, adding 2 to 3 ft. a year, attaining about 35 ft. tall and wide, and developing a rounded vase shape. The seed is central in a narrow-winged samara smaller than that of Siberian elm.Photographs and information sent from bree ...

Ulmus Pumila
''Ulmus pumila'', the Siberian elm, is a tree native to Asia. It is also known as the Asiatic elm and dwarf elm, but sometimes mistakenly called the "Chinese" elm (''Ulmus parvifolia''). ''U. pumila'' has been widely cultivated throughout Asia, North America, Argentina, and southern Europe, becoming naturalized in many places, notably across much of the United States. Description The Siberian elm is usually a small to medium-sized, often bushy, deciduous tree growing to tall, the diameter at breast height to . The bark is dark gray and irregularly longitudinally fissured. The branchlets are yellowish gray, glabrous or pubescent, unwinged, and without a corky layer, with scattered lenticels.

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...

Cultivar
A cultivar is a kind of Horticulture, cultivated plant that people have selected for desired phenotypic trait, traits and which retains those traits when Plant propagation, propagated. Methods used to propagate cultivars include division, root and stem cuttings, offsets, grafting, micropropagation, tissue culture, or carefully controlled seed production. Most cultivars arise from deliberate human genetic engineering, manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''#Formal definition, Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants t ... [...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 fruit, simple dry fruits, dry fruit, and is Dehiscence (botany), indehiscent (not Dehiscence (botany), opening along a seam). The shape of a samara enables the wind to carry the seed further 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 autorotation (helicopter), autorotate as it falls, as in the maples (genus ''Acer (plant), 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, ...
