Camillo Karl Schneider
Camillo Karl Schneider (7 April 1876 – 5 January 1951) was a German botanist and landscape architect. A farmer's son, he was born at Wermsdorf, Gröppendorf, in the Kingdom of Saxony, and worked as a gardener at Zeitz, Dresden, Berlin and Greifswald. Returning to Berlin to work in the City Parks Department, he assisted in editorial work for the periodical ''Gartenwelt'', which led to his employ as a landscape assistant in Darmstadt and Berlin. In 1900, he moved to Vienna, where he practiced as a freelance architect and writer, travelling extensively through Europe. In 1904 he published his first books, including the beginning of his tome ''Illustrated Handbook of Broad-leaved Trees'', which he completed in 1912. However, the manuscript of what should have been his ''Masterpiece, magnum opus'', a study of the genus ''Berberis'', was destroyed in a bombing raid on Berlin in 1943. In 1907 he created the specimen series ''Plantae hungaricae 1907'' distributed as an exsiccata-like seri ...

Flower
Flowers, also known as blooms and blossoms, are the reproductive structures of flowering plants ( angiosperms). Typically, they are structured in four circular levels, called whorls, around the end of a stalk. These whorls include: calyx, modified leaves; corolla, the petals; androecium, the male reproductive unit consisting of stamens and pollen; and gynoecium, the female part, containing style and stigma, which receives the pollen at the tip of the style, and ovary, which contains the ovules. When flowers are arranged in groups, they are known collectively as inflorescences. Floral growth originates at stem tips and is controlled by MADS-box genes. In most plant species flowers are heterosporous, and so can produce sex cells of both sexes. Pollination mediates the transport of pollen to the ovules in the ovaries, to facilitate sexual reproduction. It can occur between different plants, as in cross-pollination, or between flowers on the same plant or even the same f ...

Sorbus
''Sorbus'' is a genus of over 100 species of trees and shrubs in the rose family, Rosaceae. Species of ''Sorbus'' ('' s.str.'') are commonly known as rowan or mountain-ash. The genus used to include species commonly known as whitebeam, chequer tree and service tree that are now classified in other genera (see below). The genus ''Sorbus'', as currently circumscribed, includes only the pinnate leaved species of former subgenus ''Sorbus''. ''Sorbus'' is not closely related to the true ash trees which belong to the genus '' Fraxinus'', although the leaves are superficially similar. Genus As treated in its broad sense, the genus was traditionally divided into several subgenera, however, this treatment was found to be paraphyletic, comprising two disparate lineages within the Malinae subtribe. Consequently, each of the former subgenera have since been elevated into genera in their own right, with the genus name ''Sorbus'' retained only for the rowans. Additionally, it was recogni ...

Apomixis
In botany, apomixis is asexual development of seed or embryo without fertilization. However, other definitions include replacement of the seed by a plantlet or replacement of the flower by bulbils. Apomictically produced offspring are genetically identical to the parent plant, except in nonrecurrent apomixis. Its etymology is Greek for "away from" + "mixing". Normal asexual reproduction of plants, such as propagation from cuttings or leaves, has never been considered to be apomixis. In contrast to parthenocarpy, which involves seedless fruit formation without fertilization, apomictic fruits have viable seeds containing a proper embryo, with asexual origin. In flowering plants, the term "apomixis" is used in a restricted sense to mean agamospermy, i.e. clonal reproduction through seeds. Although agamospermy could theoretically occur in gymnosperms, it appears to be absent in that group. Apogamy is a related term that has had various meanings over time. In plants with ...

Sorbus Oligodonta
''Sorbus oligodonta'', also known as the kite-leaf rowan and white-fruited rowan, is a species of rowan found from the eastern Himalaya to south-central China, northern Vietnam and Myanmar. Description ''Sorbus oligodonta'' is a small to medium-sized deciduous tree growing to 5–15 m tall, with a rounded crown and dark grey bark. The leaves are green to glaucous blue-green above, paler beneath, 10–26 cm long, pinnate with 9-17 oval leaflets 3–5.5 cm long and 1–2 cm broad, broadest near the middle or apex (hence the English name 'kite-leaf'), rounded at the end with a short acuminate apex, and very finely serrated margins; the basal leaflets are smaller than the apical leaflets. They change to a dark orange-red in late autumn, later than most other rowan species. The flowers are 8 mm diameter, with five white or yellowish-white petals and 20 yellowish-white stamens; they are produced in corymbs 6–15 cm diameter in late spring to early summer. The ...

Ornamental Tree
Ornamental plants or ''garden plants'' are plants that are primarily grown for their beauty but also for qualities such as scent or how they shape physical space. Many flowering plants and garden varieties tend to be specially bred cultivars that improve on the original species in qualities such as color, shape, scent, and long-lasting blooms. There are many examples of fine ornamental plants that can provide height, privacy, and beauty for any garden. These ornamental perennial plants have seeds that allow them to reproduce. One of the beauties of ornamental grasses is that they are very versatile and low maintenance. Almost all types of plant have ornamental varieties: trees, shrubs, climbers, grasses, succulents, aquatic plants, herbaceous perennials and annual plants. Non-botanical classifications include houseplants, bedding plants, hedges, plants for cut flowers and ''foliage plants''. The cultivation of ornamental plants comes under floriculture and tree nurseries, wh ...

Variety (botany)
In botanical nomenclature, variety (abbreviated var.; in ) is a taxonomic rank below that of species and subspecies, but above that of form. As such, it gets a three-part infraspecific name. It is sometimes recommended that the subspecies rank should be used to recognize geographic distinctiveness, whereas the variety rank is appropriate if the taxon is seen throughout the geographic range of the species. Example The pincushion cactus, ''Escobaria vivipara'', is a wide-ranging variable species occurring from Canada to Mexico, and found throughout New Mexico below about . Nine varieties have been described. Where the varieties of the pincushion cactus meet, they intergrade. The variety ''Escobaria vivipara'' var. ''arizonica'' is from Arizona, while ''Escobaria vivipara'' var. ''neo-mexicana'' is from New Mexico. Definitions The term is defined in different ways by different authors. However, the International Code of Nomenclature for Cultivated Plants, while recognizing ...

Pome
In botany, a pome is a type of fruit produced by flowering plants in the subtribe Malinae of the family Rosaceae. Pome fruits consist of a central "core" containing multiple small seeds, which is enveloped by a tough membrane and surrounded by an edible layer of flesh. Pome fruit trees are deciduous, and undergo a dormant winter period that requires cold temperatures to break dormancy in spring. Well-known pomes include the apple, pear, and quince. Etymology The word ''pome'' entered English in the late 14th century, and referred to an apple or an apple-shaped object. It derived from the Old French word for "apple": (12th century; modern French is ), which in turn derived from the Late Latin or Vulgar Latin word "apple", originally the plural of Latin "fruit", later "apple". Morphology A pome is an accessory fruit composed of one or more Gynoecium, carpels surrounded by accessory tissue. The accessory tissue is interpreted by some specialists as an extension of the rece ...

Fruit
In botany, a fruit is the seed-bearing structure in flowering plants (angiosperms) that is formed from the ovary after flowering. Fruits are the means by which angiosperms disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and other animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; humans, and many other 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 and culinary 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'' als ...

Corymb
Corymb is a botanical term for an inflorescence with the flowers growing in such a fashion that the outermost are borne on longer pedicels than the inner, bringing all flowers up to a common level. A corymb has a flattish top with a superficial resemblance towards an umbel, and may have a branching structure similar to a panicle. Flowers in a corymb structure can either be parallel, or alternate, and form in either a convex, or flat form. Many species in the Maloideae, such as hawthorns and rowans, produce their flowers in corymbs. The Norway maple and yerba maté are also examples of corymbs. The word ''corymb'' is derived from the Ancient Greek Ancient Greek (, ; ) includes the forms of the Greek language used in ancient Greece and the classical antiquity, ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Greek ... word κόρυμβος, meaning "bunch of flowers or fruit". Image:Schirmtraube ...

Leaf Shape
The following terms are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflets). The edge of the leaf may be regular or irregular, and may be smooth or have hair, bristles, or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "ac ...

Rowan
The rowans ( or ) or mountain-ashes are shrubs or trees in the genus ''Sorbus'' of the rose family, Rosaceae. They are native throughout the cool temperate regions of the Northern Hemisphere, with the highest species diversity in the Himalaya, southern Tibet and parts of western China, where numerous apomictic microspecies occur.Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins . The name ''rowan'' was originally applied to the species ''Sorbus aucuparia'' and is also used for other species in the genus ''Sorbus''. Natural hybrids, often including ''S. aucuparia'' and the whitebeam, '' Aria edulis'' (syn. '' Sorbus aria''), give rise to many endemic variants in the UK. Names The Latin name ''sorbus'' was borrowed into Old English as ''syrfe''. The Latin name ''sorbus'' is from a root for "red, reddish-brown" ( PIE ''*sor-/*ser-''); English ''sorb'' is attested from the 1520s in the sense "fruit of the service tree", adopted via French ''sorbe'' from Latin ' ...
