The database IPNI gives more than 12,100 named taxa, including subspecies and synonyms. [1]

The following list consists of about 1,000 accepted species and cited synonyms. [2] Bold for endangered species.

Pilosella aurantiaca is a perennial flowering plant in the family Asteraceae that is native to alpine regions of central and southern Europe, where it is protected in several regions.

<i>Hieracium</i> Genus of flowering plants

Hieracium , known by the common name hawkweed and classically as hierakion, is a genus of flowering plant in the 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.

<i>Adenostyles</i> Genus of flowering plants

Adenostyles is a genus of flowering plants in the sunflower family Asteraceae, and of the tribe Senecioneae. It was described as a genus in 1816. Adenostyles occur in the temperate climates of the northern hemisphere, mainly in Europe and Asia Minor.

<i>Pilosella officinarum</i> Species of flowering plant in the daisy family Asteraceae

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.

<i>Hieracium hieronymi</i> Species of flowering plant

Hieracium hieronymi is a forb of genus Hieracium in the family Asteraceae. and found only in Ecuador once in a collection gathered in 1871 from Pichincha; the description included with the specimen was "Crescit prope Panecillo haud procul a praedio Hacienda Pesillo inter urben Quito et La Esperanza", and in a more recent specimen reported by L. Mille still some years ago gathered from Carchi and deposited in the Berlin Herbarium where the taxonomic problems have remained intact.

<i>Hieracium lachenalii</i> Species of flowering plant

Hieracium lachenalii, also known as common hawkweed or yellow hawkweed, is a species of plant in the tribe Cichorieae within the family Asteraceae. 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.

<i>Pilosella caespitosa</i> Species of flowering plant in the daisy family Asteraceae

<i>Hieracium horridum</i> Species of flowering plant in the family Asteraceae

Hieracium horridum, known as the prickly hawkweed or shaggy hawkweed, is a species of plant in the family Asteraceae. It gets its name from the long, dense, shaggy white to brown hairs (trichomes) which cover all of the plant parts of this plant species. The species is native to Oregon, California, and Nevada in the western United States.

<i>Ligularia sibirica</i> Species of flowering plant

Ligularia sibirica is the type species for the genus Ligularia. It is a 0.3-1.3 m tall perennial herbaceous plant, native to fens and damp grassy meadows in Siberia, Central and Eastern Europe. Once fairly common, it has disappeared from many places in Europe, owing to drainage of wetlands and competition from other plants invading its natural habitats; when growing in shade plants do not flower or set seed very well and seed germination is greatly reduced. This species is sometimes grown in gardens for its large leaves and tall spike like arrangement of yellow daisy like flowers.

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.

<i>Pilosella lactucella</i> Species of flowering plant in the daisy family Asteraceae

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.
