Hickory
Hickory is a common name for trees composing the genus ''Carya'', which includes around 18 species. Five or six species are native to China, Indochina, and India (Assam), as many as twelve are native to the United States, four are found in Mexico, and two to four are native to Canada. A number of hickory species are used for products like edible nuts or wood. Hickories are temperate forest trees with pinnately compound leaves and large nuts. Hickory flowers are small, yellow-green catkins produced in spring. They are wind-pollinated and self-incompatible. The fruit is a globose or oval nut, long and diameter, enclosed in a four- valved husk, which splits open at maturity. The nut shell is thick and bony in most species, and thin in a few, notably the pecan (''C. illinoinensis''); it is divided into two halves, which split apart when the seed germinates. Etymology The name "hickory" derives from a Native American word in an Algonquian language (perhaps Powhatan). It i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carya Tomentosa
''Carya tomentosa'', (mockernut hickory, mockernut, white hickory, whiteheart hickory, hognut, bullnut) is a tree in the Juglandaceae or walnut family. The most abundant of the hickories, common in the eastern half of the US, it is long lived, sometimes reaching the age of 500 years. A straight-growing hickory, a high percentage of its wood is used for products where strength, hardness, and flexibility are needed. The wood makes excellent fuel wood, as well. The leaves turn yellow in Autumn. The species' name comes from the Latin word ''tomentum'', meaning "covered with dense, short hairs," referring to the underside of the leaves, which help identify the species. Also called the white hickory due to the light color of the wood, the common name mockernut likely refers to the would-be nut eater, who would struggle to crack the thick shell only to find a small, unrewarding nut inside. Habitat Native range Mockernut hickory, a true hickory, grows from Massachusetts and New York w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juglandaceae
The Juglandaceae are a plant family known as the walnut family. They are trees, or sometimes shrubs, in the order Fagales. Members of this family are native to the Americas, Eurasia, and Southeast Asia. The nine or ten genera in the family have a total of around 50 species, and include the commercially important nut-producing trees walnut (''Juglans''), pecan (''Carya illinoinensis''), and hickory (''Carya''). The Persian walnut, '' Juglans regia'', is one of the major nut crops of the world. Walnut, hickory, and gaulin are also valuable timber trees while pecan wood is also valued as cooking fuel. Description Members of the walnut family have large, aromatic leaves that are usually alternate, but opposite in '' Alfaroa'' and '' Oreomunnea''. The leaves are pinnately compound or ternate, and usually 20–100 cm long. The trees are wind-pollinated, and the flowers are usually arranged in catkins. The fruits of the Juglandaceae are often confused with drupes but are acc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beaked Hickory
''Annamocarya'' is a genus of flowering plants in the family Juglandaceae, containing only one species, ''Annamocarya sinensis'', native to southwestern China (Guangxi, Guizhou, Yunnan) and northern Vietnam. It is related to the hickories, and was formerly included in the same genus ''Carya'', as ''Carya sinensis'', but also shares a number of characteristics with the walnuts in the genus ''Juglans''. It is grouped with ''Carya'' in the subtribe Caryinae. It is sometimes called Chinese hickory or beaked hickory. It is a medium-sized to large evergreen tree growing to tall. The leaves are long, and pinnate with 7–11 leaflets. The leaflets have an entire margin, which distinguishes it from ''Carya'', where the leaflets have a serrated margin. The flowers are catkins produced in spring, with the male catkins in clusters of five to eight together (single in ''Carya''). The fruit In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Powhatan Language
Powhatan or Virginia Algonquian was an Eastern Algonquian subgroup of the Algonquian languages. It was formerly spoken by the Powhatan people of tidewater Virginia. Following 1970s linguistic research by Frank Thomas Siebert, Jr., some of the language has been reconstructed with assistance from better-documented Algonquian languages, and attempts are being made to revive it. The sole documentary evidence for this language is two short wordlists recorded around the time of first European contact. William Strachey recorded about 500 words and Captain John Smith recorded only about 50 words. Smith also reported the existence of a pidgin form of Powhatan, but virtually nothing is known of it. Strachey's material was collected sometime between 1610 and 1611, and probably written up from his notes in 1612 and 1613, after he had returned to England. It was never published in his lifetime, although he made a second copy in 1618. The second copy was published in 1849, and the first ...

Nut (fruit)
A nut is a fruit consisting of a hard or tough nutshell protecting a kernel which is usually edible. In general usage and in a culinary sense, a wide variety of dry seeds are called nuts, but in a botanical context "nut" implies that the shell does not open to release the seed ( indehiscent). Most seeds come from fruits that naturally free themselves from the shell, but this is not the case in nuts such as hazelnuts, chestnuts, and acorns, which have hard shell walls and originate from a compound ovary. The general and original usage of the term is less restrictive, and many nuts (in the culinary sense), such as almonds, pecans, pistachios, walnuts, and Brazil nuts, are not nuts in a botanical sense. Common usage of the term often refers to any hard-walled, edible kernel as a nut. Nuts are an food energy, energy-dense and nutrient-rich food source. Botanical definition A seed is the mature fertilised ovule of a plant; it consists of three parts, the embryo which will d ...

Catkin
A catkin or ament is a slim, cylindrical flower cluster (a spike), with inconspicuous or no petals, usually wind-pollinated (anemophilous) but sometimes insect-pollinated (as in '' Salix''). They contain many, usually unisexual flowers, arranged closely along a central stem that is often drooping. They are found in many plant families, including Betulaceae, Fagaceae, Moraceae, and Salicaceae. Occurrence Catkin-bearing plants include many trees or shrubs such as birch, willow, aspen, hickory, sweet chestnut, and sweetfern (''Comptonia''). In many of these plants, only the male flowers form catkins, and the female flowers are single ( hazel, oak), a cone (alder), or other types (mulberry). In other plants (such as poplar), both male and female flowers are borne in catkins. In Britain, they can be seen in January or February, when many trees are bare for winter. They can even occur in December. Evolution For some time, catkins were believed to be a key synapomorp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anemophily
Anemophily or wind pollination is a form of pollination whereby pollen is distributed by wind. Almost all gymnosperms are anemophilous, as are many plants in the order Poales, including grasses, sedges, and rushes. Other common anemophilous plants are oaks, pecans, pistachios, sweet chestnuts, alders and members of the family Juglandaceae (hickory or walnut family). Approximately 12% of plants across the globe are pollinated by anemophily, including cereal crops like rice and corn and other prominent crop plants like wheat, rye, barley, and oats. In addition, many pines, spruces, and firs are wind-pollinated, and. Syndrome Features of the wind-pollination syndrome include a lack of scent production, a lack of showy floral parts (resulting in small, inconspicuous flowers), reduced production of nectar, and the production of enormous numbers of pollen grains. This distinguishes them from entomophilous and zoophilous species (whose pollen is spread by insects and vert ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Milk
Plant milk is a plant beverage with a color resembling that of milk. Plant milks are non-dairy beverages made from a water-based plant extract for flavoring and aroma. Plant milks are consumed as alternatives to milk, and often provide a creamy mouthfeel. There are about 17 different types of plant milks; almond, oat, soy, and coconut are the highest-selling worldwide. Production of plant-based milks, particularly soy and oat milks, can offer environmental advantages over animal milks in terms of greenhouse gas emissions, land and water use. Plant-based beverages have been consumed for centuries, with the term "milk-like plant juices" used since the 13th century. Today they are frequently referred to as ''plant-based milk'', ''alternative milk'', ''non-dairy milk'' or ''vegan milk''. For commerce, plant-based beverages are typically packaged in containers similar and competitive to those used for dairy milk, but cannot be labeled as "milk" within the European Union. Across ...

APG System
The APG system (Angiosperm Phylogeny Group system) of plant classification is the first version of a modern, mostly molecular-based, system of plant taxonomy. Published in 1998 by the Angiosperm Phylogeny Group, it was replaced by the improved APG II in 2003, APG III system in 2009 and APG IV system in 2016. History The original APG system is unusual in being based, not on total evidence, but on the cladistic analysis of the DNA sequences of three genes, two chloroplast genes and one gene coding for ribosomes. Although based on molecular evidence only, its constituent groups prove to be supported by other evidence as well, for example pollen morphology supports the split between the eudicots and the rest of the former dicotyledons. The system is rather controversial in its decisions at the family level, splitting a number of long-established families and submerging some other families. It also is unusual in not using botanical names above the level of order, that is, an orde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Native American Languages
Over a thousand indigenous languages are spoken by the Indigenous peoples of the Americas. These languages cannot all be demonstrated to be related to each other and are classified into a hundred or so language families (including a large number of language isolates), as well as a number of extinct languages that are unclassified because of a lack of data. Many proposals have been made to relate some or all of these languages to each other, with varying degrees of success. The most notorious is Joseph Greenberg's Amerind hypothesis, which however nearly all specialists reject because of severe methodological flaws; spurious data; and a failure to distinguish cognation, contact, and coincidence. Nonetheless, there are indications that some of the recognized families are related to each other, such as widespread similarities in pronouns (e.g., ''n''/''m'' is a common pattern for 'I'/'you' across western North America, and ''ch''/''k''/''t'' for 'I'/'you'/'we' is similarly found ...

Germination
Germination is the process by which an organism grows from a seed or spore. The term is applied to the sprouting of a seedling from a seed of an angiosperm or gymnosperm, the growth of a sporeling from a spore, such as the spores of fungi, ferns, bacteria, and the growth of the pollen tube from the pollen grain of a seed plant. Seed plants Germination is usually the growth of a plant contained within a seed; it results in the formation of the seedling. It is also the process of reactivation of metabolic machinery of the seed resulting in the emergence of radicle and plumule. The seed of a vascular plant is a small package produced in a fruit or cone after the union of male and female reproductive cells. All fully developed seeds contain an embryo and, in most plant species some store of food reserves, wrapped in a seed coat. Some plants produce varying numbers of seeds that lack embryos; these are empty seeds which never germinate. Dormant seeds are viable seeds th ...

Husk
Husk (or hull) in botany is the outer shell or coating of a seed. In the United States, the term husk often refers to the leafy outer covering of an ear of maize (corn) as it grows on the plant. Literally, a husk or hull includes the protective outer covering of a seed, fruit, or vegetable. It can also refer to the exuvia of insects or other small animals left behind after moulting. In cooking, hull can also refer to other waste parts of fruits and vegetables, notably the cap or sepal of a strawberry. The husk of a legume and some similar fruits is called a pod. Husking and dehulling Husking of corn is the process of removing its outer layers, leaving only the cob or seed rack of the corn. Dehulling is the process of removing the hulls (or chaff) from beans and other seeds. This is sometimes done using a machine known as a huller. To prepare the seeds to have oils extracted from them, they are cleaned to remove any foreign objects. Next, the seeds have their hulls, ...
