Conyza Podocephala
''Conyza'' (horseweed, butterweed or fleabane) is a genus of flowering plants in the family Asteraceae. They are native to tropical and warm temperate regions throughout the world, and also north into cool temperate regions in North America and eastern Asia. The New World species of the genus are closely related to ''Erigeron'' (also known as fleabanes). The species are annual plant, annual or perennial plant, perennial herbaceous plants, rarely shrubs, growing to 1–2 m tall. The stems are erect, branched, with alternate leaf, leaves. The flowers are produced in inflorescences, with several inflorescences loosely clustered on each stem. Many species of the genus ''Conyza'' are ruderal species and some have been found to be resistant to the herbicide glyphosate. ; Species References External links Germplasm Resources Information Network: ''Conyza''Chinese plant names: ''Conyza'' {{Authority control Astereae Asteraceae genera Ruderal species ...

Flower
Flowers, also known as blooms and blossoms, are the reproductive structures of flowering plants ( angiosperms). Typically, they are structured in four circular levels, called whorls, around the end of a stalk. These whorls include: calyx, modified leaves; corolla, the petals; androecium, the male reproductive unit consisting of stamens and pollen; and gynoecium, the female part, containing style and stigma, which receives the pollen at the tip of the style, and ovary, which contains the ovules. When flowers are arranged in groups, they are known collectively as inflorescences. Floral growth originates at stem tips and is controlled by MADS-box genes. In most plant species flowers are heterosporous, and so can produce sex cells of both sexes. Pollination mediates the transport of pollen to the ovules in the ovaries, to facilitate sexual reproduction. It can occur between different plants, as in cross-pollination, or between flowers on the same plant or even the same f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Many species of the genus ''Conyza'' are ruderal species and some have been found to be resistant to the herbicide glyphosate Glyphosate (IUPAC name: ''N''-(phosphonomethyl)glycine) is a broad-spectrum systemic herbicide and crop desiccant. It is an organophosphorus compound, specifically a phosphonate, which acts by EPSP inhibitor, inhibiting the plant enzyme 5-en .... ...
