Oak vs La D

Informations

An oak is a tree or shrub in the genus Quercus (; Latin "oak tree") of the beech family, Fagaceae. There are approximately 500 extant species of oaks. The common name "oak" also appears in the names of species in related genera, notably Lithocarpus (stone oaks), as well as in those of unrelated species such as Grevillea robusta (silky oaks) and the Casuarinaceae (she-oaks). The genus Quercus is native to the Northern Hemisphere, and includes deciduous and evergreen species extending from cool temperate to tropical latitudes in the Americas, Asia, Europe, and North Africa. North America contains the largest number of oak species, with approximately 90 occurring in the United States, while Mexico has 160 species of which 109 are endemic. The second greatest center of oak diversity is China, which contains approximately 100 species.

Oaks have spirally arranged leaves, with lobate margins in many species; some have serrated leaves or entire leaves with smooth margins. Many deciduous species are marcescent, not dropping dead leaves until spring. In spring, a single oak tree produces both male flowers (in the form of catkins) and small female flowers, meaning that the trees are monoecious. The fruit is a nut called an acorn or oak nut borne in a cup-like structure known as a cupule; each acorn contains one seed (rarely two or three) and takes 6–18 months to mature, depending on their species. The acorns and leaves contain tannic acid, which helps to guard from fungi and insects. The live oaks are distinguished for being evergreen, but are not actually a distinct group and instead are dispersed across the genus.

Fiorello Henry La Guardia (; born Fiorello Raffaele Enrico La Guardia, Italian pronunciation: [fjoˈrɛllo raf.faˈɛ.le enˈriːko la ˈɡwardja]; December 11, 1882 – September 20, 1947) was an American attorney and politician who represented New York in the House of Representatives and served as the 99th Mayor of New York City from 1934 to 1946. He was known for his irascible, energetic, and charismatic personality and diminutive, rotund stature. A socialist member of the Republican Party, La Guardia was frequently cross-endorsed by parties other than his own, especially parties on the left under New York's electoral fusion laws. A panel of 69 scholars in 1993 ranked him first among the ten best mayors in American history. He was born to Italian immigrants in New York City. Before serving as mayor, La Guardia represented Manhattan in Congress and on the New York City Board of Aldermen. As mayor, during the Great Depression and World War II, La Guardia unified the city's transit system; expanded construction of public housing, playgrounds, parks, and airports; reorganized the New York Police Department; and implemented federal New Deal programs within the city.

He pursued a long series of political reforms, curbing the power of the powerful Irish-controlled Tammany Hall political machine that controlled the Democratic Party in Manhattan. He also re-established merit-based employment and promotion within city administration. La Guardia was also a highly visible national political figure. His support for the New Deal and relationship with President Franklin D. Roosevelt crossed party lines, brought federal funds to New York City, and cut off patronage to La Guardia's Tammany enemies. La Guardia's WNYC radio program "Talk to the People", which aired from December 1941 until December 1945, expanded his public influence beyond the borders of the city.
