Garryales
The Garryales are a small order of dicotyledons, including only two families and three genera. Description Garryales are woody plants that are either hairless or have very fine hairs. Members of the family Garryaceae are evergreen, whereas those of the Eucommiaceae are deciduous and produce latex. All members are dioecious. Taxonomy These belong among the asterids. Under the Cronquist system, the Garryaceae were placed among the Cornales. The Eucommiaceae were given their own order and placed among the Hamamelidae. The Oncothecaceae family has been associated with Garryales, though the link is not strong enough to prove they are related. Subdivisions The order is made up of two families which, between them, contain three genera. These are: * Family Garryaceae **'' Garrya'' **'' Aucuba'' * Family Eucommiaceae **''Eucommia'' Distribution Species in the order are spread between North America and Asia. The various ''Garrya'' species are found in North America, in southern and w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Asterid
In the APG IV system (2016) for the classification of flowering plants, the name asterids denotes a clade (a monophyletic group). Asterids is the largest group of flowering plants, with more than 80,000 species, about a third of the total flowering plant species. Well-known plants in this clade include the common daisy, forget-me-nots, nightshades (including potatoes, eggplants, tomatoes, chili peppers and tobacco), the common sunflower, petunias, yacon, morning glory, sweet potato, coffee, lavender, lilac, olive, jasmine, honeysuckle, ash tree, teak, snapdragon, sesame, psyllium, garden sage, table herbs such as mint, basil, and rosemary, and rainforest trees such as Brazil nut. Most of the taxa belonging to this clade had been referred to as Asteridae in the Cronquist system (1981) and as Sympetalae in earlier systems. The name asterids (not necessarily capitalised) resembles the earlier botanical name but is intended to be the name of a clade rather than a formal ...

Angiosperm Orders
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils are in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eucommiaceae
''Eucommia'' is a genus of small trees now native to China, with a fossil record that shows a much wider distribution. The single living species, ''Eucommia ulmoides'', is near threatened in the wild, but is widely cultivated in China for its bark, and is highly valued in herbology such as traditional Chinese medicine. Description Modern ''Eucommia'' trees grow to about 15 m tall. The leaves are deciduous, arranged alternately, simple ovate with an acuminate tip, long, and with a serrated margin. If a leaf is torn across, strands of latex exude from the leaf veins and solidify into rubber and hold the two parts of the leaf together. It flowers from March to May with the flowers being inconspicuous, small, and greenish. The fruits ripen between June and November and are a winged samara with one seed, very similar to an elm samara in appearance. The modern fruits are long and broad, while fruits of the extinct species range up to long. ''Eucommia'' is dioecious, with sep ...

Dicotyledon
The dicotyledons, also known as dicots (or, more rarely, dicotyls), are one of the two groups into which all the flowering plants (angiosperms) were formerly divided. The name refers to one of the typical characteristics of the group: namely, that the seed has two embryonic leaves or cotyledons. There are around 200,000 species within this group. The other group of flowering plants were called monocotyledons (or monocots), typically each having one cotyledon. Historically, these two groups formed the two divisions of the flowering plants. Largely from the 1990s onwards, molecular phylogenetic research confirmed what had already been suspected: that dicotyledons are not a group made up of all the descendants of a common ancestor (i.e., they are not a monophyletic group). Rather, a number of lineages, such as the magnoliids and groups now collectively known as the basal angiosperms, diverged earlier than the monocots did; in other words, monocots evolved from within the dic ...

Aucuba Japonica
''Aucuba japonica'', commonly called spotted laurel, Japanese laurel, Japanese aucuba or gold dust plant (U.S.), is a shrub () native to rich forest soils of moist valleys, thickets, by streams and near shaded moist rocks in China, Korea, and Japan. This is the species of ''Aucuba'' commonly seen in gardens - often in variegated form. The leaves are opposite, broad lanceolate, long and wide. ''Aucuba japonica'' are dioecious. The flowers are small, diameter, each with four purplish-brown petals; they are produced in clusters of 10-30 in a loose cyme. The fruit is a red drupe approximately in diameter that is avoided by birds. The variegation, considered by some to be an attractive property, is caused by 'Aucuba bacilliform', a putative species of virus in the genus ''Badnavirus. History ''Aucuba japonica'' was introduced into England in 1783 by Philip Miller's pupil John Graeffer, at first as a plant for a heated greenhouse. It became widely cultivated as the "gold ...

Aucuba
''Aucuba'' is a genus of three to ten species of flowering plants, now placed in the family Garryaceae, although formerly classified in the Aucubaceae or Cornaceae. ''Aucuba'' species are native to eastern Asia, from the eastern Himalayas east to China, Korea, and Japan. The name is a latinization of Japanese ''Aokiba''. They are evergreen shrubs or small trees 2–13 m tall, similar in appearance to the laurels of the genus ''Laurus'', having glossy, leathery leaves, and are among the shrubs that are mistakenly called laurels in gardens."With characteristic perversity, we deny the name of laurel to the only member of that genus that we cultivate—''Laurus nobilis''—which we call the Bay, and bestow it on a number of totally unconnected shrubs", observes Alice M. Coats. The leaves are opposite, broad lanceolate, 8–25 cm long and 2–7 cm broad, with a few large teeth on the margin near the apex of the leaf. Aucubas are dioecious, having separate male and fema ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Garrya
''Garrya'' is a genus of flowering plants in the family Garryaceae native to Mexico, the western United States, Central America and the Greater Antilles. Common names include silk tassel and tassel bush. They are evergreen dioecious wind-pollinated shrubs growing to tall. The leaves are arranged in opposite pairs, and are simple, leathery, dark green to gray-green, ovate, long, with an entire margin and a short petiole. The flowers are gray-green catkins, short and spreading when first produced in late summer; the male catkins becoming long () and pendulous in late winter when shedding pollen; the female catkins usually a little shorter and less pendulous. The fruit is a round dry berry containing two seeds.
