Erechtites Valerianifolia
''Erechtites'' is a genus of flowering plants in the daisy family known commonly as fireweeds or burnweeds. They are native to the Americas and Australia, but some species are widely distributed weeds. Description ''Erechtites'' consists of Annual plant, annual or Perennial plant, perennial herbs with large taproots and very often with a pungent odor. Leaves are usually Leaf shape, ovate or lanceolate (sometimes Leaf shape, pinnately lobed or pinnatifid). Flower heads may sometimes contain as many as 100 yellow or white (rarely pink) disc florets but no ray florets. Taxonomy and species Some species in this genus are treated as members of ''Senecio'' by some authors, and several other species are considered variants of ''Erechtites hieraciifolius'', so there may be as few as 5 distinct species in this genus. In particular, not all authors agree on whether to include a dozen or so species native to Australia and New Zealand in ''Erechtites''. ;Species 27 species are recognise ...

Erechtites Hieraciifolius
''Erechtites hieraciifolius'' (fireweed, American burnweed, or pilewort) is a plant in the daisy family, Asteraceae. It is native to the Americas, but is found many places around the world having been introduced by human activity. It is introduced in Hawaii, China, and Southeast Asia. Description ''Erechtites hieraciifolius'' is an annual herb with alternate, simple leaves, on thick, green stems. The leaves are serrated, and range from unlobed to deeply lobed, with the lobe pattern superficially resembling wild lettuces, which are in the same family but not closely related. When crushed, all parts of the species are aromatic. The flower heads are yellow or pink, borne in fall. The heads are followed by cluster of small, wispy achenes. The plant often branches and grows in a clump with multiple stems. Ecology This species benefits from fire, and is often one of the earliest pioneer species of areas that have recently burned, hence some of its common names. It prefers moist ...

Asia
Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area of , about 30% of Earth's total land area and 8.7% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, ...

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

West Indies
The West Indies is a subregion of North America, surrounded by the North Atlantic Ocean and the Caribbean Sea that includes 13 independent island countries and 18 dependencies and other territories in three major archipelagos: the Greater Antilles, the Lesser Antilles, and the Lucayan Archipelago. The subregion includes all the islands in the Antilles, plus The Bahamas and the Turks and Caicos Islands, which are in the North Atlantic Ocean. Nowadays, the term West Indies is often interchangeable with the term Caribbean, although the latter may also include some Central and South American mainland nations which have Caribbean coastlines, such as Belize, French Guiana, Guyana, and Suriname, as well as the Atlantic island nations of Barbados, Bermuda, and Trinidad and Tobago, all of which are geographically distinct from the three main island groups, but culturally related.

It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.
