In biological taxonomy , the type genus is the genus which defines a biological family and the root of the family name.
73-415: See text Wallia Alef Walnut trees are any species of tree in the plant genus Juglans , the type genus of the family Juglandaceae , the seeds of which are referred to as walnuts . All species are deciduous trees, 10–40 metres (33–131 ft) tall, with pinnate leaves 200–900 millimetres (7.9–35.4 in), with 5–25 leaflets; the shoots have chambered pith , a character shared with

The common walnut, and the black walnut and its allies, are important for their attractive timber, which is hard, dense, tight-grained and polishes to a very smooth finish. The color is dark chocolate or similar in the heartwood changing by a sharp boundary to creamy white in the sapwood. When kiln-dried, walnut wood tends toward
219-638: A nitrogen fixing plant, such as Elaeagnus × ebbingei or Elaeagnus umbellata , and various Alnus species, results in a 30% increase in tree height and girth (Hemery 2001). When grown for nuts, care must be taken to select cultivars that are compatible for pollination purposes; although some cultivars are marketed as "self fertile", they will generally fruit better with a different pollination partner. Many different cultivars are available for growers, and offer different growth habits, flowering and leafing, kernel flavours and shell thicknesses. A key trait for more northerly latitudes of North America and Europe
292-619: A retail and housing boom in the late 1980s that continued until the mid-1990s. Also in the 1970s, the Market Street Redevelopment Project, established in 1968, began the development of the Midtown Mall. The mall was established to prevent further property deterioration and to restore and maintain the economic health of the downtown area's commercial and retail activity. The mall suffered multiple difficulties. The passage of Proposition 13 in 1978 reduced

The type genus for a family-group name is also the genus that provided the stem to which was added the ending -idae (for families). In botanical nomenclature , the phrase "type genus" is used, unofficially, as a term of convenience. In the ICN this phrase has no status. The code uses type specimens for ranks up to family, and types are optional for higher ranks. The Code does not refer to

Walnuts are very attractive trees in parks and large gardens. Walnut trees are easily propagated from the nuts. Seedlings grow rapidly on good soils. The Japanese walnut in particular is known for its huge leaves, which have
511-449: A dull brown color, but when air-dried can become a rich purplish-brown. Because of its color, hardness and grain, it is a prized furniture and carving wood. When walnut vascular cambium is involved in a crotch (a branch fork), it behaves unusually, producing characteristic "crotch figure" in the wood which it makes. The grain figure exposed when a crotch in a walnut log is cut in the plane of its one entering branch and two exiting branches

The fruits of the walnut are a type of accessory fruit known as a pseudodrupe (or drupe-like nut), the outer covering of the fruit is an involucre - in a drupe the covering would be derived from the carpel. The nut kernels of all the species are edible, but the walnuts most commonly traded are from

Most recently,
803-514: A seemingly great distance outside the drip line can be affected, and juglone can linger in the soil for several years even after a walnut is removed as its roots slowly decompose and release juglone into the soil. Walnut species are used as food plants by the larvae of some Lepidoptera species. These include: The nuts are consumed by other animals, such as mice and squirrels. In California (US) and Switzerland, crows have been witnessed taking walnuts into their beaks, flying up to 60 feet or so in

Eastern black walnut ( J. nigra ) shell is the hardest of the walnut shells, and therefore has the highest resistance to breakdown. Walnut husks are often used to create a rich yellow-brown to dark brown dye used for dyeing fabric , yarn or wood and for other purposes. The dye does not require
949-408: A tropical appearance. As garden trees, they have some drawbacks, in particular the falling nuts, and the releasing of the allelopathic compound juglone , though a number of gardeners do grow them. However, different walnut species vary in the amount of juglone they release from the roots and fallen leaves - J. nigra , in particular, is known for its toxicity, both to plants and horses. Juglone

Some cultivars have been developed for novel ‘hedge’ production systems developed in Europe and would not suit more traditional orchard systems. The leaves and blossoms of the walnut tree normally appear in spring. The male cylindrical catkins are developed from leafless shoots from the past year; they are about 10 cm (3.9 in) in length and have

Juglone appears to be one of the walnut's primary defence mechanisms against potential competitors for resources (water, nutrients and sunlight), and its effects are felt most strongly inside the tree's "drip line" (the circle around the tree marked by the horizontal distance of its outermost branches). However, even plants at
