Hieracium , known by the common name hawkweed and classically as hierakion, is a genus of flowering plant in the sunflower family Asteraceae, and closely related to dandelion (Taraxacum), chicory (Cichorium), prickly lettuce (Lactuca) and sow thistle (Sonchus), which are part of the tribe Cichorieae. Hawkweeds, with their 10,000+ recorded species and subspecies, do their part to make Asteraceae the second largest family of flowering plants. Some botanists group all these species or subspecies into approximately 800 accepted species, while others prefer to accept several thousand species. Since most hawkweeds reproduce exclusively asexually by means of seeds that are genetically identical to their mother plant, clones or populations that consist of genetically identical plants are formed and some botanists prefer to accept these clones as good species whereas others try to group them into a few hundred more broadly defined species. What is here treated as the single genus Hieracium is now treated by most European experts as two different genera, Hieracium and Pilosella, with species such as Hieracium pilosella, Hieracium floribundum and Hieracium aurantiacum referred to the latter genus. Many members of the genus Pilosella reproduce both by stolons and by seeds, whereas true Hieracium species reproduce only by seeds. In Pilosella, many individual plants are capable of forming both normal sexual and asexual (apomictic) seeds, whereas individual plants of Hieracium only produce one kind of seeds. Another difference is that all species of Pilosella have leaves with smooth (entire) margins whereas most species of Hieracium have distinctly dentate to deeply cut or divided leaves.
A dry roadside dotted with small, ¾ inch red orange flowers, interspersed with very similar yellow ones, and often the white of daisies, is a good sign that you are in Hawkweed country.
Pilosella officinarum, known as mouse-ear hawkweed, is a yellow-flowered species of flowering plant in the daisy family Asteraceae, native to Europe and northern Asia. It produces single, lemon-coloured inflorescences. Like most hawkweed species, it is highly variable and is a member of a species complex of several dozens of subspecies and hundreds of varieties and forms. It is an allelopathic plant.
Talinum fruticosum is a herbaceous perennial plant that is native to Mexico, the Caribbean, West Africa, Central America, and much of South America. Common names include Ceylon spinach, waterleaf, cariru, Gbure, Surinam purslane, Philippine spinach, Florida spinach, potherb fameflower, Lagos bologi, sweetheart, and Kutu bataw in Ghana from the Akan language It is widely grown in tropical regions as a leaf vegetable.
Pilosella albiflora is a common and widespread North American plant in the sunflower family, known by the names white hawkweed and white-flowered hawkweed.
Hieracium umbellatum, the Canadian hawkweed, Canada hawkweed, narrowleaf hawkweed, or northern hawkweed, is a flowering plant in the daisy family Asteraceae.
Hieracium lachenalii, also known as common hawkweed or yellow hawkweed, is a species of plant in the dandelion tribe within the sunflower family. It is native to Europe but has become established as a weed in Australia and parts of North America. The species was widely known for many years as H. vulgatum, but more recent studies have indicated that the two names represent the same species. The name H. lachenalii was coined in 1802, H. vulgatum in 1819, so the older name is to be used.
Pilosella caespitosa is like several other Pilosella species and has a similar appearance to many of the hawkweeds.
Hieracium sabaudum, also known as New England hawkweed, European hawkweed or a Savoy hawkweed, is a European species of plants in the dandelion tribe within the sunflower family. It is native to Europe but has become naturalized in parts of North America. In Canada, it grows in British Columbia, Québec, and Nova Scotia. In the United States, it has been found in Washington state in the Northwest as well as Wisconsin and the Northeast. The species is considered a noxious weed in Washington state.
Hieracium albertinum, known as western hawkweed or houndstongue hawkweed, is a species of the genus Hieracium that is very similar to Hieracium albiflorum with white flowers but differs in that the flower heads are clustered and the leaves, stems and bracts are covered in a thick layer of hairs. Standing 1 inch (3 cm) to 5 inches (13 cm) tall, it can be found blooming from June through August in forest clearings.
Hieracium laevigatum, or smooth hawkweed, is a Eurasian plant species in the dandelion tribe within the sunflower family. It is widespread across much of Europe and western Asia. It is very similar to Hieracium sabaudum and can be found on dry, more or less nutrient rich soil in light woods, grassy embankments and fields, or on walls.
Oxyptilus pilosellae is a moth of the family Pterophoridae first described by Philipp Christoph Zeller in 1841. It is found in most of Europe, east to Russia and Asia Minor. It was released as a biological control agent for Hieracium in New Zealand in 1998.
Platylobium triangulare , commonly known as ivy flat-pea, is a shrub species that is endemic to Australia. It is a member of the family Fabaceae and of the genus Platylobium. The species was formally described in 1812 by botanist Robert Brown in Hortus Kewensis. The type specimen was collected in Tasmania by Brown.
Pilosella floribunda is a species of noxious and herbaceous perennial plant from family Asteraceae that is known in Europe and can also be found in United States and Canada. It was believed that it was a hybrid of Pilosella caespitosa (Hieracium caespitosum and Pilosella lactucella.
Pilosella lactucella is a species of perennial plant from the family Asteraceae, found in Europe, New York and Nova Scotia (Canada). It is 9–20 centimetres (3.5–7.9 in) in height, with stems from 1–2 millimetres (0.039–0.079 in) wide. The leaves are spatula shaped and 5–8 centimetres (2.0–3.1 in) wide. The flowers bloom from May to July, the heads of which are 2–5 centimetres (0.79–1.97 in) tall. It was once described by Carl Linnaeus as Hieracium auricula and Pilosella auricula, but was recategorized by A. E. Roland and M. Zinck in 1998.
Hieracium murorum, the wall hawkweed, is a species of flowering plant in the sunflower family. It is native to Europe and naturalized in some of the colder regions of North America.
Dendrolobium triangulare is a species of flowering plants in the legume family, Fabaceae. It is found in Taiwan, China, Cambodia, India, Laos, Malaysia, Myanmar, Nepal, Sri Lanka, Thailand, Vietnam and few African countries. Leaves are trifoliate, where blade narrowly obovo-elliptic. Flowers white or pale yellow. Seed elliptic. Roots of the plant are widely used for medicinal purposes to strengthen bones and build muscle.
Hieracium traillii is a species of hawkweed known by the common name Maryland hawkweed.
Hieracium bolanderi or Bolander's hawkweed is a North American plant species in the dandelion tribe within the sunflower family. It is found primarily in the mountains of western Oregon and northern California in the United States, although there are reports of the species farther south in the San Bernardino Mountains in southern California and also in Baja California in Mexico.
Hieracium gronovii or queendevil is a North American plant species in the dandelion tribe within the sunflower family. It is common and widespread across much of the continent from Ontario south as far as Florida, the Dominican Republic, and Panamá.
