Malus crescimannoi Raimondo | |
Malus crescimannoi, also known as the Raimondo apple, is a species of apple in the rose family, Rosaceae. Native to the island of Sicily, it was formally described only in 2008, making it one of the most recently described species of tree in Europe. At present unknown is whether the species is a remnant of a preglacial diversity of apples in Europe, or a distinctive race of European wild apple.
It is a small to medium-sized tree of up to 10 metres (33 ft) in size, that is distinguished from the European wild apple and the domestic apple by a combination of smaller flowers, more oval leaves and small (2.5 to 4 centimetres or 1 to 1+1⁄2 inches in diameter) pomes that are usually longer than wide. [2] [3] The flowers appear in corymbs in April to May, with petals that are pink to purple in colour. The apple fruits ripen in October to November. The leaves are hairy with long petioles. The twigs are weakly thorny. [2] [3]
Although formally described in 2008, the species was recognised as different from other local apple populations much earlier. Further investigation by botanist Francesco Raimondo then demonstrated that the population is relatively uniform in its characteristics and distinct from other populations, which led to its formal description as a distinct species. Nonetheless, the species is clearly closely related to both the domestic apple ( Malus domestica ) and the European wild apple ( M. sylvestris ), and could still turn out to be a distinctive local race of the latter. [2] The species epiphet honours Francesco Giulio Crescimanno, arborist and professor at the University of Palermo. [2]
The species is endemic to Sicily, a characteristic it shares with other Sicilian woody plants such as the Sicilian fir ( Abies nebrodensis ), Mount Etna broom ( Genista aetnensis ) and Sicilian zelkove ( Zelkova sicula ). It is also the only species of apple endemic to Italy, the other two wild species (M. sylvestris and M. florentina ) being more widely distributed in Europe. The species was originally described from the Nebrodi mountains near Floresta, but was more recently also identified in the Madonie Mountains. [4] The area is recognised as the largest remaining area of Sicilian forest and is home to a number of endemic species. [5] Malus crescimannoi occurs in plant communities dominated by oaks ( Quercus cerris and Q. petraea ) and European beech ( Fagus sylvatica ), alongside fellow medium-sized rosaceous species such as the chequer tree ( Torminalis glaberrima ), pears ( Pyrus pyraster , P. spinosa , and P. ciancioi ) and locally the closely related European crab apple, as well as hawthorns ( Crataegus monogyna and C. orientalis ), blackthorn ( Prunus spinosa ) and dog rose ( Rosa canina ). It can be a common member of these communities between 1,000 and 1,800 m (3,300 and 5,900 ft) in altitude. [3] [4]
The species is known from only two populations in two locations in the Sicilian Apennines of northern Sicily. The Italian Red List classifies it as near threatened, and it is also recognised as a threatened crop wild relative of the domestic apple. [6]
Rosaceae, the rose family, is a family of flowering plants that includes 4,828 known species in 91 genera.
Malus is a genus of about 32–57 species of small deciduous trees or shrubs in the family Rosaceae, including the domesticated orchard apple, crab apples and wild apples.
Prunus cerasifera is a species of plum known by the common names cherry plum and myrobalan plum. It is native to Southeast Europe and Western Asia, and is naturalised in the British Isles and scattered locations in North America. Also naturalized in parts of SE Australia where it is considered to be a mildly invasive weed of bushland near urban centers. P. cerasifera is believed to one of the parents of the cultivated plum, Prunus domestica perhaps crossing with the sloe, Prunus spinosa, or perhaps the sole parent. This would make it a parent of most of the commercial varieties of plum in the UK and mainland Europe - Victoria, greengages, bullace etc.
Malus sieversii is a wild apple. According to DNA analysis conducted in 2010, it is the primary ancestor of the domesticated apple, M. domestica.
Malus sylvestris, the European crab apple, also known as the European wild apple or simply the crab apple, is a species of the genus Malus. Its scientific name means "forest apple", reflecting its habitat. It is native to Eurasia.
Macromeles tschonoskii is a species of flowering plant in the family Rosaceae. It is a tree endemic to Japan.
An apple is a round, edible fruit produced by an apple tree. Apple trees are cultivated worldwide and are the most widely grown species in the genus Malus. The tree originated in Central Asia, where its wild ancestor, Malus sieversii, is still found. Apples have been grown for thousands of years in Eurasia and were introduced to North America by European colonists. Apples have religious and mythological significance in many cultures, including Norse, Greek, and European Christian tradition.
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 many parts of 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 toringoides is a crabapple species in the family Rosaceae, with the common name cut-leaf crabapple.
Malus trilobata, the Lebanese wild apple, erect crab apple or three-lobed apple tree, is a species in the family Rosaceae in the genus Malus. Some authorities place it in the segregate genus Eriolobus, as E. trilobatus.
Pyrus pyraster, also called European wild pear, is a species of pear of the family Rosaceae.
Prunus domestica is a species of flowering plant in the family Rosaceae. A deciduous tree, it includes many varieties of the fruit trees known as plums in English, though not all plums belong to this species. The greengages and damsons also belong to subspecies of P. domestica.
The South Apennine mixed montane forests is an ecoregion in the southern Apennine Mountains of southern Italy and Sicily. It has a Mediterranean climate, and is in the Mediterranean forests, woodlands, and scrub biome.
Coleophora anatipennella is a moth of the case-bearer family (Coleophoridae).
Stigmella oxyacanthella is a moth of the family Nepticulidae, found in Europe and North America. The larvae are leaf miners feeding inside the leaves of trees and shrubs, such as hawthorn, apple and pear.
Pyrus bourgaeana, the Iberian pear, is a close relative of Pyrus communis L. The latter was domesticated about 2500 years ago. This small tree is widely distributed across the southern Iberian Peninsula and northern Morocco, where it coexists with four Pyrus species: P. communis L., P. cordata Dew., P. spinosa Forssk, and P. nivalis Jacq. Characteristics to discriminate these species are the width of fruit peduncle, petal size, leaf width and petiole length served to the taxa.
Malinae is the name for the apple subtribe in the rose family, Rosaceae. This name is required by the International Code of Nomenclature for algae, fungi, and plants, which came into force in 2011 for any group at the subtribe rank that includes the genus Malus but not either of the genera Rosa or Amygdalus. The group includes a number of plants bearing commercially important fruits, such as apples and pears, while others are cultivated as ornamentals.
Malus niedzwetzkyana, or Niedzwetzky's apple, is a kind of apple native to Asia noted for its red-fleshed, red-skinned fruit and red flowers. Some botanists consider it a distinct species, while others have argued that it is simply an unusual variety of the common apple. It is likely endangered.
Phyllocoptes malinus, also known as the apple leaf mite, is a species of mite belonging to the genus Phyllocoptes. It causes a gall, which is a swelling on the external tissues, on the leaves of apples. The mite is found in Europe and was first described by the Austrian zoologist Alfred Nalepa in 1892.
Dasineura mali, commonly known as the apple leaf curling midge, apple leaf midge [English], Cécidomyie du pommier [French], Appelbladgalmug [Dutch], or Apfelblattgallen [German],is a species of gall midge belonging to the family Cecidomyiidae, within the order Diptera.
