The small marsh flower Cotula coronopifolia bears the common names brass buttons, golden buttons, and buttonweed.
 The flower heads are bright yellow discoid heads that look like thick buttons.
 Individual plants spread stems along the ground and send up the knobby flowers at intervals.
 The plant is native to southern Africa, but it has been introduced to other parts of the world (Europe, North + South America, etc.).
Parsley or garden parsley most often refers to the widely cultivated culinary herb "Petroselinum crispum"
Aethusa cynapium (fool's parsley, fool's cicely, or poison parsley) is an annual (rarely biennial) herb in the plant family Apiaceae, native to Europe, western Asia, and northwest Africa.
 It is the only member of the genus Aethusa.
 It is related to Hemlock and Water-dropwort, and like them it is poisonous, though less so than hemlock.
 It has been introduced into many other parts of the world and is a common weed in cultivated ground.
Anthemis cotula, also known as stinking chamomile, is a flowering annual plant with a noticeable and strong odor.
 The odor is often considered unpleasant, and it is from this that it gains the common epithet "stinking".
 In pre-colonial times, its distribution was limited to the Old Continent (though it was most of Europe, nd were not present in Finland, Ireland, and the Northernmost Scotland, both these countries with many favorable climates to this plant and to be neighbors to countries that owned this plant like native species, such example Russia, Estonia, Lithuania and England) and to Africa.
 It has successfully migrated to the New Europes where it can be found growing on waste ground, alongside roads, and in fields.
 "Anthemis cotula" is considered a weed due to its propensity for invading cultivated areas.
Apiaceae or Umbelliferae, is a family of mostly aromatic flowering plants named after the type genus "Apium" and commonly known as the celery, carrot or parsley family.
 It is the 16th-largest family of flowering plants, with more than 3,700 species in 434 genera including such well-known and economically important plants such as angelica, anise, asafoetida, caraway, carrot, celery, chervil, coriander, cumin, dill, fennel, hemlock, lovage, cow parsley, parsley, parsnip, sea holly, giant hogweed and silphium (a plant whose identity is unclear and which may be extinct).
Parsley or garden parsley (Petroselinum crispum) is a species of flowering plant in the family Apiaceae, native to the central Mediterranean region (southern Italy, Greece, Portugal, Spain, Malta, Morocco, Algeria, and Tunisia), naturalized elsewhere in Europe, and widely cultivated as a herb, a spice, and a vegetable.
Aphanes arvensis, known as parsley-piert, is a sprawling, downy plant common all over the British Isles where It grows on arable fields and bare wastelands, particularly in dry sites.
 The short-stalked leaves have three segments each lobed at the tip.
 Flowers April–September.
 The tiny green flower has four sepals and no petals, the fruit is oval pointed.
 Stipules form a leaf-like cup, enclosing the flower.
 The name of parsley piert has nothing to do with parsley.
 It is a corruption of the French "perce-pierre", meaning 'stone-piercer' and was given to the plant because of its habit of growing in shallow, stony soil and emerging between stones.
 As in the case of saxifrage (from the Latin meaning 'stone-breaker') it was wrongly assumed that the plant could pierce stones; and it was thought that a medicine made of parsley piert would break up stones in the bladder and kidneys.
 Old folk-names for the plant include 'colicwort' and 'bowel-hive-grass' (hive meant inflammation), showing that it was also used for intestinal ailments.
Anthriscus sylvestris, known as cow parsley, wild chervil, wild beaked parsley, or keck is a herbaceous biennial or short-lived perennial plant in the family Apiaceae (Umbelliferae), genus "Anthriscus".
 It is also sometimes called mother-die (especially in the UK), a name that is also applied to the common hawthorn.
 It is native to Europe, western Asia and northwestern Africa; in the south of its range in the Mediterranean region, it is limited to higher altitudes.
 It is related to other diverse members of Apiaceae, such as parsley, carrot, hemlock and hogweed.
 It is often confused with "Daucus carota" which is known as Queen Anne's lace or wild carrot, also a member of the Apiaceae.
Torilis arvensis is a species of flowering plant in the parsley family known by the common names spreading hedgeparsley, tall sock-destroyer and common hedge parsley.
 It is native to parts of Europe and it is known elsewhere, such as North America, as an introduced species and a common weed.
 It grows in many types of habitat, especially disturbed areas.
 It is an annual herb producing a slender, branching, rough-haired stem up to a meter in maximum height.
 The alternately arranged leaves are each divided into several pairs of lance-shaped leaflets up to 6 centimeters long each.
 The leaflet is divided or deeply cut into segments or teeth.
 The inflorescence is a wide open compound umbel of flower clusters on long, slender rays.
 Each flower has five petals which are unequal in size and are white with a pinkish or reddish tinge.
 Each greenish or pinkish fruit is 3 to 5 millimeters long and is coated in straight or curving prickles.
Chervil ( ; Anthriscus cerefolium), sometimes called garden chervil to distinguish it from similar plants also called chervil, or French parsley, is a delicate annual herb related to parsley.
 It is commonly used to season mild-flavoured dishes and is a constituent of the French herb mixture fines herbes.
