Xiphydria
''Xiphydria'' is a genus of wood wasps belonging to the family Xiphydriidae. This genus is Holarctic The Holarctic realm is a biogeographic realm that comprises the majority of habitats found throughout the continents in the Northern Hemisphere. It corresponds to the floristic Boreal Kingdom. It includes both the Nearctic zoogeographical reg ..., being found in Europe, Asia and North America. Description In ''Xiphydria'', the head has mandibles each with four teeth, 5-segmented maxillary palps, a clypeus with a medial tooth-like projection and antennae with about 20 segments. The pronotum is strongly constricted in dorsal view and the propleuron is long in lateral view (this means the head is positioned on a relatively long "neck"). The hind wing has only two closed cells. Larvae are white and grub-like. They resemble larvae of Siricidae, another wood-boring group of sawflies. Biology Female ''Xiphydria'' oviposit into diseased or dead wood, often branches tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Xiphydriidae
Xiphydriidae are a family of wood wasps that includes around 150 species. They are located all over the world including North and South America, Australia, Europe, and others. Xiphydriidae larvae are wood borers in dead trees or branches of a range of trees. They are characterized as having long and skinny necks with dome-shaped heads. The oldest fossils of the group are from the mid Cretaceous. Genera These 29 genera belong to the family Xiphydriidae: * '' Alloxiphia'' Wei, 2002 * '' Austrocyrta'' Riek, 1955 * '' Austroxiphyda'' Jennings, Macdonald, Schiff & Parslow, 2021 * '' Brachyxiphus'' Philippi, 1871 * '' Calexiphyda'' Smith, 2008 * '' Carinoxiphia'' Wei, 1999 * '' Derecyrta'' Smith, 1860 * '' Eoxiphia'' Maa, 1949 * '' Euxiphydria'' Semenov-Tian-Shanskii & Gussakovskii, 1935 * '' Genaxiphia'' Maa, 1949 * '' Gryponeura'' Benson, 1954 * '' Heteroxiphia'' Saini & Singh, 1987 * '' Hyperxiphia'' Maa, 1949 * '' Indoxiphia'' Maa, 1949 * '' Lataxiphyda'' Smith, 2008 * '' Lissoxiph ...

Prunus
''Prunus'' is a genus of flowering plant, flowering trees and shrubs from the family (biology), family Rosaceae. The genus includes plums, cherries, peaches, nectarines, apricots and almonds (collectively Drupe, stonefruit). The genus has a cosmopolitan distribution, being native to the temperate regions of North America, the neotropics of South America, and temperate and tropical regions of Eurasia and Africa, There are about 340 accepted species . Many members of the genus are widely cultivated for their sweet, fleshy fruit and for decorative purposes of their flowers. ''Prunus'' fruit are drupes, or stone fruits. The fleshy Fruit anatomy, mesocarp surrounding the Fruit anatomy, endocarp is edible while the endocarp itself forms a hard, inedible shell called the pyrena ("stone" or "pit"). This shell encloses the seed (or "kernel"), which is edible in some species (such as sweet almonds), but poisonous in many others (such as apricot kernels). Besides being eaten off the hand, m ...

Hornbeam
Hornbeams are hardwood trees in the plant genus ''Carpinus'' in the family Betulaceae. Its species occur across much of the temperateness, temperate regions of the Northern Hemisphere. Common names The common English name ''hornbeam'' derives from the hardness of the woods (likened to Horn (anatomy), horn) and the Old English ''beam'', "tree" (cognate with Dutch ''Boom'' and German ''Baum''). The American hornbeam is also occasionally known as blue-beech, ironwood, or musclewood, the first from the resemblance of the bark to that of the American beech ''Fagus grandifolia'', the other two from the hardness of the wood and the muscled appearance of the trunk and limbs. The botanical name for the genus, ''Carpinus'', is the original Latin name for the European species, although some etymologists derive it from the Celtic for a yoke. Description Hornbeams are small, slow-growing, understory trees with a natural, rounded form growing tall and wide; the exemplar species—the ...

Ostrya
''Ostrya'' is a genus of eight to 10 small deciduous trees belonging to the birch family Betulaceae. Common names include hop-hornbeam and hophornbeam. It may also be called ironwood, a name shared with a number of other plants. The genus is native in southern Europe, southwest and eastern Asia, and North America, North and Central America. They have a conical or irregular crown and a scaly, rough bark. They have alternate and double-toothed birch-like leaf, leaves 3–10 cm long. The flowers are produced in spring, with male catkins 5–10 cm long and female aments 2–5 cm long.

Tilia
''Tilia'' is a genus of about 30 species of trees or bushes, native throughout most of the temperateness, temperate Northern Hemisphere. The tree is known as linden for the European species, and basswood for North American species. In Great Britain and Ireland they are commonly called lime trees, although they are not related to the citrus Lime (fruit), lime. The genus occurs in Europe and eastern North America, but the greatest species diversity is found in Asia. Under the Cronquist system, Cronquist classification system, this genus was placed in the family Tiliaceae, but genetic research summarised by the Angiosperm Phylogeny Group has resulted in the incorporation of this genus, and of most of the previous family, into the Malvaceae. ''Tilia'' is the only known ectomycorrhizal genus in the family Malvaceae. Studies of ectomycorrhizal relations of ''Tilia'' species indicate a wide range of fungal symbionts and a preference toward Ascomycota fungal partners. Description ''T ...

Fraxinus
''Fraxinus'' (), commonly called ash, is a genus of plants in the olive and lilac family, Oleaceae, and comprises 45–65 species of usually medium-to-large trees, most of which are deciduous trees, although some Subtropics, subtropical species are evergreen trees. The genus is widespread throughout much of Europe, Asia, and North America. The leaves are opposite leaves, opposite (rarely in Whorl (botany), whorls of three), and mostly pinnate, pinnately compound, though simple in a few species. The seeds, popularly known as "keys" or "helicopter seeds", are a type of fruit known as a samara (fruit), samara. Some ''Fraxinus'' species are Dioecy, dioecious, having male and female flowers on separate plants but sex in ash is expressed as a continuum between male and female individuals, dominated by unisexual trees. With age, ash may change their sexual function from predominantly male and hermaphrodite towards femaleness; if grown as an ornamental and both sexes are present, ashes ...

Beech
Beech (genus ''Fagus'') is a genus of deciduous trees in the family Fagaceae, native to subtropical (accessory forest element) and temperate (as dominant element of Mesophyte, mesophytic forests) Eurasia and North America. There are 14 accepted species in two distinct subgenera, ''Englerianae'' and ''Fagus''. The subgenus ''Englerianae'' is found only in East Asia, distinctive for its low branches, often made up of several major trunks with yellowish bark. The better known species of subgenus ''Fagus'' are native to Europe, western and eastern Asia and eastern North America. They are high-branching trees with tall, stout trunks and smooth silver-grey bark. The European beech ''Fagus sylvatica'' is the most commonly cultivated species, yielding a utility timber used for furniture construction, flooring and engineering purposes, in plywood, and household items. The timber can be used to build homes. Beechwood makes excellent firewood. Slats of washed beech wood are spread around ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
