Malus is a genus of about 30–55 species of small deciduous trees or shrubs in the family Rosaceae, including the domesticated orchard apple – also known as the eating apple, cooking apple, or culinary apple. The other species are commonly known as crabapples, crab apples, crabtrees, wild apples, or rainberries.
Malus sieversii is a wild apple native to the mountains of Central Asia in southern Kazakhstan. It has recently been shown to be the primary ancestor of most cultivars of the domesticated apple. It was first described as Pyrus sieversii due to its similarities with pears in 1833 by Carl Friedrich von Ledebour, a German naturalist who saw them growing in the Altai Mountains.
Malus sylvestris, the European crab apple, is a species of the genus Malus, native to Europe. Its scientific name means "forest apple" and the truly wild tree has thorns.
The American Elm cultivar Ulmus americana 'Lake City' was first described by Wyman in Trees Magazine 3 (4): 13, 1940.
The American Elm cultivar Ulmus americana 'Columnaris' was propagated from a tree found by Mr John Dunbar at Conesus Lake, New York, before 1920. The tree should not be confused with U. americana var. columnarisRehder,J. Arnold Arbor. 3: 42, 1922.
The possible elm cultivar Ulmus 'Jalaica' hails from the Baltic states. Living specimens are grown in the arboretum at the National Botanic Garden of Latvia, Salaspils, introduced in 1998 from the Tallinn Botanic Garden and the plantarium OPU Tallinn, Estonia. It was assumed the word 'Jalaica' was the name given the cultivar, but it has since emerged that the word simply means 'Elm' in Estonian, and the trees donated may not in fact be cultivars, although of rather unusual appearance.
Malus floribunda, common name Japanese flowering crabapple, Japanese crab, purple chokeberry, or showy crabapple, originates from Japan and East Asia. It may be a hybrid of M. sieboldii with M. baccata, in which case it would be written as Malus × floribunda.
Malus coronaria, also known by the names sweet crabapple or garland crab, is a North American species of Malus (crabapple). It grows primarily in the Great Lakes Region and in the Ohio Valley, with outlying populations as far away as Alabama, eastern Kansas, and Long Island.
Malus hupehensis, common names Chinese crab apple, Hupeh crab or tea crabapple, is a species of flowering plant in the apple genus Malus of the family Rosaceae.
Oxanthera brevipes is a species of plant in the family Rutaceae. It is endemic to New Caledonia. It was proposed as a novel species by Benjamin C. Stone based on two specimens, distinguished from other false oranges by a non-articulated petiole. The genus Oxanthera has been synonymized with Citrus, but a name in Citrus does not appear to have been published, and Plants of the World Online regards "Oxanthera brevipes" as an unplaced name.
Malus baccata is an Asian species of apple known by the common names Siberian crab apple, Siberian crab, Manchurian crab apple and Chinese crab apple. It is native to much of northern Asia, but is also grown elsewhere as an ornamental tree and for rootstock. It is used for bonsai. It bears plentiful fragrant white flowers and edible red to yellow fruit of about 1 cm diameter.
Malus prunifolia is a species of crabapple tree known by the common names plumleaf crab apple, plum-leaved apple, pear-leaf crabapple, Chinese apple and Chinese crabapple. It is native to China, and is grown elsewhere for use as an ornamental tree or as rootstock. It reaches from between 3 and 8 meters tall and bears white flowers and yellow or red fruit.
Malus sargentii, the Sargent crabapple or Sargent's apple, is a species of flowering plant in the genus Malus of the family Rosaceae. The species was formerly considered a variety of the species Malus sieboldii. It is a shrub or small tree growing to 6–10 ft (1.8–3.0 m) tall and 6–12 ft (1.8–3.7 m) broad.
Malus sieboldii, commonly called Siebold's crab, Siebold's crabapple or Toringo crabapple, is a species of crabapple in the family Rosaceae.
Grevillea johnsonii, commonly known as Johnson's grevillea or Johnson's spider flower, is a species of flowering plant in the family Proteaceae and is endemic to New South Wales. It is a shrub with divided, needle-like leaves and red to orange flowers, and grows in rocky places.
Malus niedzwetzkyana, or Niedzwetzky's apple, is a kind of apple native to certain parts of China, Afghanistan, Kazakhstan, Kyrgyzstan, and Uzbekistan noted for its red-fleshed, red-skinned fruit and red flowers. Some botanists consider it a distinct species, while others have argued it is simply an unusual variety of the common apple, Malus pumila.
Applecrabs are various hybrids between crabapples and apples. They are bred for varying reasons, including disease resistance and use in cold climates because they are often hardier than apple trees and their fruit has the good eating qualities of apples.
Malus × robusta, called Siberian crab apple along with other members of its genus, is a hybrid species of flowering plant in the family Rosaceae. It is the result of a cross between Malus baccata and Malus prunifolia. It is being studied for its resistance potential to fire blight. Known for its attractive fruit that remain on the tree well into winter, its cultivar 'Red Sentinel' has gained the Royal Horticultural Society's Award of Garden Merit as an ornamental.
Paranomus longicaulis, commonly known as exploding baked apple and woolly sceptre, is a flower-bearing shrub that belongs to the genus Paranomus and forms part of the fynbos. The plant is native to the Western Cape where it occurs on the eastern Langeberg from Garcia Pass to the Attakwaskloof.
