Polypyrenous Drupe
In botany, a pome is a type of fruit produced by flowering plants in the subtribe Malinae of the family Rosaceae. 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 carpels surrounded by accessory tissue. The accessory tissue is interpreted by some specialists as an extension of the receptacle and is then referred to as "fruit cortex",Esau, K. 1977. ''Anatomy of seed plants''. John Wiley and Sons, New York. and by others as a fused hypanthium (floral cup). It is the most edible part of this fruit. The carpels of a pome are fused within the "core".

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 ...

Toyon
''Heteromeles arbutifolia'' (; more commonly by Californian botanists), commonly known as toyon, is a common perennial shrub native to extreme southwest Oregon, California, and the Baja California Peninsula. It is the sole species in the genus ''Heteromeles''. Toyon is a prominent component of the coastal sage scrub plant community, and is a part of drought-adapted chaparral and mixed oak woodland habitats. It is also known by the common names Christmas berry and California holly. Description Toyon typically grows from 2–5 m (rarely up to 10 m in shaded conditions) and has a rounded to irregular top. Its leaves are evergreen, alternate, sharply toothed, have short petioles, and are 5–10 cm in length and 2–4 cm wide. In the early summer it produces small white flowers 6–10 mm diameter in dense terminal corymbs. Flowering peaks in June. The five petals are rounded. The fruit is a small pome, 5–10 mm across, bright red and berry-like, prod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loquat
The loquat (''Eriobotrya japonica'') is a large evergreen shrub or tree, grown commercially for its orange fruit and for its leaves, which are used to make herbal tea. It is also cultivated as an ornamental plant. The loquat is in the family Rosaceae, and is native to the cooler hill regions of south-central China. In Japan the loquat is known as biwa (枇杷, びわ) and has been grown for over 1,000 years. The loquat has been introduced to regions with subtropical to mild temperate climates throughout the world. ''Eriobotrya japonica'' was formerly thought to be closely related to the genus ''Mespilus'', and is still sometimes mistakenly known as the Japanese medlar. It is also known as Japanese plum and Chinese plum, as well as pipa in China, naspli in Malta, Lukaat in India, Lucat in Sri Lanka, níspero in Spain, nêspera in Portugal, shések in Israel, akidéné in Lebanon, Ebirangweti in Kisii and nespolo in Italy (where the name is shared with ''Mespilus germanica''). ...

Pyracantha
''Pyracantha'' (from Greek "fire" and "thorn", hence firethorn) is a genus of large, thorny evergreen shrubs in the family Rosaceae, with common names firethorn or pyracantha. They are native to an area extending from Southwest Europe east to Southeast Asia.

Medlar
''Mespilus germanica'', known as the medlar or common medlar, is a large shrub or small tree in the rose family Rosaceae. The fruit of this tree, also called medlar, has been cultivated since Roman times, is usually available in winter and eaten when bletted. It may be eaten raw and in a range of cooked dishes. When the genus ''Mespilus'' is included in the genus '' Crataegus'', the correct name for this species is ''Crataegus germanica'' (Kuntze). In the southwest of England it historically had a number of vulgar nicknames, such as open-arse and monkey's bottom, due to the appearance of its large calyx. Description Under ideal circumstances, the deciduous plant grows up to tall. Generally, it is shorter and more shrub-like than tree-like. With a lifespan of 30–60 years, the tree is rather short-lived. Its bark is grayish brown with deep vertical cracks forming rectangular plates that tend to lift off. The wild form of ''M. germanica'' is mostly a thorny, more shrub-like ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mespilus Germanica 01
''Mespilus'', commonly called medlar, is a monotypic genus of flowering plants in the family Rosaceae containing the single species ''Mespilus germanica'' of southwest Asia. It is also found in some countries in the Balkans, especially in Albanian regions. A second proposed species, ''Mespilus canescens'', discovered in North America in 1990, proved to be a hybrid between ''M. germanica'' and one or more species of hawthorn, and is properly known as ×'' Crataemespilus canescens''. Plant ''Mespilus'' forms deciduous large shrubs to small trees growing up to tall. The fruit is a matte brown pome. History ''Mespilus germanica'' is apparently native only to southwest Asia and southeastern Europe, i.e. near the Black Sea coast and western Mediterranean, and Asia Minor, as well as the Caucasus and northern Iran, but it has an ancient history of cultivation and wild plants exist in a much wider area; it was grown by the ancient Greeks and Romans, beginning in the second century B ...

Ovary (plants)
In the flowering plants, an ovary is a part of the female reproductive organ of the flower or gynoecium. Specifically, it is the part of the pistil which holds the ovule(s) and is located above or below or at the point of connection with the base of the petals and sepals. The pistil may be made up of one carpel or of several fused carpels (e.g. dicarpel or tricarpel), and therefore the ovary can contain part of one carpel or parts of several fused carpels. Above the ovary is the style and the stigma, which is where the pollen lands and germinates to grow down through the style to the ovary, and, for each individual pollen grain, to fertilize one individual ovule. Some wind pollinated flowers have much reduced and modified ovaries. Fruits A fruit is the mature, ripened ovary of a flower following double fertilization in an angiosperm. Because gymnosperms do not have an ovary but reproduce through double fertilization of unprotected ovules, they produce naked seeds that do not ...

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...
