The parsley frogs or Pelodytidae are a family of order Anura.
 The family consists of just one genus, Pelodytes, which contains only three species.
 These frogs can be found in southwestern Europe and the Caucasus.
 The common name of "parsley frogs" comes from the common parsley frog ("Pelodytes punctatus") which, because of its colouring, looks garnished with parsley.
Caucalis platycarpos is a species of flowering plants in the carrot family, the only member of the genus Caucalis.

Polytaenia nuttallii is a species of flowering plant in the carrot family known by the common name Nuttall's prairie parsley, or simply prairie parsley.
 It is native to the central and midwestern United States.
Lomatia silaifolia, commonly known as crinkle bush or parsley fern, is a plant of the family, Proteaceae native to eastern Australia.
 Naturally found in open forest, it grows as a small shrub 1–2 m high with highly pinnate leaves reminiscent of parsley.
 The white inflorescences appear in summer.
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.
Oncidium, abbreviated as Onc.
 in the horticultural trade, is a genus that contains about 330 species of orchids from the subtribe Oncidiinae of the orchid family (Orchidaceae).
 As presently conceived (May 2014), it is distributed across much of South America, Central America, Mexico and the West Indies, with one species "(O. ensatum)" extending into Florida.
 Common names for plants in this genus include dancing-lady orchid and golden shower orchid.
Lomatium is a genus of about 75 species of perennial herbs native to western North America.
 In the Apiaceae family and related to many edible species such as carrots and celery, it is also edible.
 The common names for it are biscuitroot, Indian parsley, and desert parsley, and was extensively used by Indians in the inland northwest as a staple food.
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 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.
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 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.
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.
