Shipova
The shipova (× ''Sorbopyrus irregularis'' ( Münchh.) C.A.Wimm.) is a hybrid of the European pear ('' Pyrus communis'') and the common whitebeam (''Sorbus aria''). It is a small to medium-sized tree growing to 10–18 m tall (or 4 - 6 m on dwarfing rootstock), with deciduous oval leaves 7–11 cm long and 5–6 cm broad. The fruit is a pome 2.5–3 cm long; it is edible with a sweet, yellowish flesh, which tastes similar to a Nashi pear. History The hybrid, known as the Bollwiller pear, first arose at Bollwiller in Alsace, France, before 1612, and has mostly been propagated by grafting since then; it is nearly sterile, only rarely producing any viable seeds. Two successful seedling propagations have been named as the cultivar 'Bulbiformis' and as the species ''Pyrus malifolia'', but shipova trees are not widely cultivated. Shipova is the only known species in the nothogenus × ''Sorbopyrus'' (the hybrid genus of '' Sorbus'' and ''Pyrus Pears are f ...

Seed
A seed is an embryonic plant enclosed in a protective outer covering, along with a food reserve. The formation of the seed is a part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiosperm plants. Seeds are the product of the ripened ovule, after the embryo sac is fertilized by sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote, and grows within the mother plant to a certain size before growth is halted. The seed coat arises from the integuments of the ovule. Seeds have been an important development in the reproduction and success of vegetable gymnosperm and angiosperm plants, relative to more primitive plants such as ferns, mosses and liverworts, which do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological niches on land, from forests to grasslands both in hot and cold climates. The term "seed" also has a general me ...

Hybrid Fruit
Hybrid fruits are created through the controlled speciation of fruits that creates new varieties and cross-breeds. Hybrids are grown using plant propagation to create new cultivars. This may introduce an entirely new type of fruit or improve the properties of an existing fruit.

× Sorbocotoneaster
The multiplication sign, also known as the times sign or the dimension sign, is the symbol , used in mathematics to denote the multiplication operation and its resulting product. While similar to a lowercase X (), the form is properly a four-fold rotationally symmetric saltire. History The earliest known use of the symbol to represent multiplication appears in an anonymous appendix to the 1618 edition of John Napier's . This appendix has been attributed to William Oughtred, who used the same symbol in his 1631 algebra text, , stating:"Multiplication of species .e. unknownsconnects both proposed magnitudes with the symbol 'in' or : or ordinarily without the symbol if the magnitudes be denoted with one letter." Two earlier uses of a notation have been identified, but do not stand critical examination.

× Amelasorbus
× ''Amelasorbus'' is a flowering plant in the family Rosaceae. A naturally occurring hybrid, it is the result of a cross between two distinct tree genera, ''Amelanchier'' and '' Sorbus'', and shows phenotypic similarities to both parents. This type of intergeneric hybrid is quite rare, and is indicated by a multiplication symbol before the name. The name ''Amelasorbus'' is an example of a portmanteau word, a combination of the two parents' names. Species There is only one accepted species, ×''Amelasorbus jackii'', ( Jack's amelasorbus) the result of '' Amelanchier alnifolia''×''Sorbus scopulina''. A specimen was discovered growing in Idaho, and described by Alfred Rehder of the Arnold Arboretum The Arnold Arboretum of Harvard University is a botanical research institution and free public park, located in the Jamaica Plain and Roslindale neighborhoods of Boston, Massachusetts.

Pyrus
Pears are fruits produced and consumed around the world, growing on a tree and harvested in the Northern Hemisphere in late summer into October. The pear tree and shrub are a species of genus ''Pyrus'' , in the family Rosaceae, bearing the pomaceous fruit of the same name. Several species of pears are valued for their edible fruit and juices, while others are cultivated as trees. The tree is medium-sized and native to coastal and mildly temperate regions of Europe, North Africa, and Asia. Pear wood is one of the preferred materials in the manufacture of high-quality woodwind instruments and furniture. About 3,000 known varieties of pears are grown worldwide, which vary in both shape and taste. The fruit is consumed fresh, canned, as juice, or dried. Etymology The word ''pear'' is probably from Germanic ''pera'' as a loanword of Vulgar Latin ''pira'', the plural of ''pirum'', akin to Greek ''apios'' (from Mycenaean ''ápisos''), of Semitic origin (''pirâ''), meaning "fruit ...

Sorbus
''Sorbus'' is a genus of over 100 species of trees and shrubs in the rose family, Rosaceae. Species of ''Sorbus'' (''s.l.'') are commonly known as whitebeam, rowan ( mountain-ash) and service tree. The exact number of species is disputed depending on the circumscription of the genus, and also due to the number of apomictic microspecies, which some treat as distinct species, but others group in a smaller number of variable species.
