Conyza Canadensis
''Erigeron canadensis'' (synonym ''Conyza canadensis'') is an annual plant native throughout most of North America and Central America. It is also widely naturalized in Eurasia and Australia. Common names include horseweed, Canadian horseweed, Canadian fleabane, coltstail, marestail, and butterweed. It was the first weed to have developed glyphosate resistance, reported in 2001 from Delaware. Description ''Erigeron canadensis'' is an annual plant growing to 1.5 m (60 in) tall, with sparsely hairy stems. The leaves are unstalked, slender, long, and up to 1 cm (0.4 inches) across, with a coarsely toothed margin. They grow in an alternate spiral up the stem and the lower ones wither early. The flowers are produced in dense inflorescences 1 cm in diameter. Each individual flower has a ring of white or pale purple ray florets and a centre of yellow disc florets. The fruit is a cypsela tipped with dirty white down. ''Erigeron canadensis'' can easily be confused with ...

Plantago
''Plantago'' is a genus of about 200 species of flowering plants in the family Plantaginaceae, commonly called plantains or fleaworts. The common name plantain is shared with the unrelated cooking plantain. Most are herbaceous plants, though a few are subshrubs growing to tall. Description The leaves are sessile or have a poorly defined petiole. They have three or five parallel veins that diverge in the wider part of the leaf. Leaves are broad or narrow, depending on the species. The inflorescences are borne on stalks typically tall, and can be a short cone or a long spike, with numerous tiny wind-pollinated flowers. Species The boundaries of the genus ''Plantago'' have been fairly stable, with the main question being whether to include ''Bougueria'' (one species from the Andes) and ''Littorella'' (2–3 species of aquatic plants).Albach, D. C., Meudt, H. M. & Oxelman, B. 2005Piecing together the "new" Plantaginaceae ''American Journal of Botany'' 92: 297–315. There are a ...

Plantago Psyllium
''Plantago indica'', commonly known as branched plantain, sand plantain, or black psyllium, is a flowering plant in the plantain family Plantaginaceae, and is one of a few species in the ''Plantago'' genus under the common name psyllium. The plant is native to parts of Africa, Europe, Russia, and Asia, and has been naturalized in many other areas such as Australia and North America. The plant can be found mostly in dry inland areas, such as those that are sandy, and has also naturalized on roadsides and in meadows. The plant is not used broadly as a food source, but has been cultivated for its seeds which serve a medicinal use as a laxative. Description ''Plantago indica'' is an annual herb with a taproot that has an erect stem with leaves that are usually opposite but sometimes in whorls of 3, and elongated internodes between leaf sets. Glandular pubescence is found on the stems, leaves, sepals, and inflorescences. The leaves are simple and have a base that is decurrent onto th ...

Senecio
''Senecio'' is a genus of flowering plants in the daisy family (Asteraceae) that includes ragworts and groundsels. Variously circumscribed taxonomically, the genus ''Senecio'' is one of the largest genera of flowering plants. Description Morphology The flower heads are normally rayed with the heads borne in branched clusters, and usually completely yellow, but green, purple, white and blue flowers are known as well. In its current circumscription, the genus contains species that are annual or perennial herbs, shrubs, small trees, aquatics or climbers. The only species which are trees are the species formerly belonging to '' Robinsonia'' occurring on the Juan Fernández Islands. Chemistry Pyrrolizidine alkaloids are found in all ''Senecio'' species. These alkaloids serve as a natural biocides to deter or even kill animals that would eat them. Livestock generally do not find them palatable. ''Senecio'' species are used as food plants by the larvae of some Lepidoptera species t ...
