Catsear is palatable to horses, and as such they will seek it out when found growing in Dry weight per plant was least in the mown lawns and greatest in grazed pasture; the greatest vegetative weight was achieved under heavy grazing and the highest reproductive weight under lax grazing. Jeju Island, Hypochaeris radicata L. mainly grows in areas with frequent aperiodic physical disturbance (Lee et al., 2001). Lamp C; Collet F, 1976. The botanical name of this plant is Hypochaeris radicata. CSIRO Canberra. According to several sources (Fryxel, 1957; Parker 1975), H. radicata is cross-pollinated and self-incompatible. Leaves can be rather bitter, although young leaves are milder. Effects of elevated soil copper on phenology, growth and reproduction of five ruderal plant species.

H. radicata is superior to many grasses in nutritive value and is comparable to white clover, being high in protein, low in fibre, exceptionally high in calcium and quite good for copper content (Coop et al., 1953). spotted catsear. Newman EI; Rovira AD, 1975. H. radicata leaves have been used as in salads or cooked as a vegetable (PFAF, 2013). The most common plant species that have been found and identified in pastures where affected horses were located include: flatweed (Hypochaeris radicata), sheep's sorrel (Rumex acetosella) and couch grass (Elymus repens).The type of nerve damage sustained in horses with Australian stringhalt suggests a mould toxin or a fungal 'poison' found in the soils may be a cause for this condition. In the Sheffield area it was associated with 197 other species, almost all species of open grassland like Agrostis capillaris, Anthoxanthum odoratum, Festuca rubra, Holcus lanatus, Lolium perenne and Trifolium spp. In: Illustrated Flora of Entre Rios Province (Argentina) [ed. Improvement of tussock grassland. Struik (1967) found that 20% of his sampled plants (in lawns and grazed pasture) were in clusters of two to six individuals, presumably originating by vegetative reproduction of a single plant. New Zealand Journal of Agricultural Research, 17(2):165-175. (1981) also found that dry storage (in their case for 12 months at 5oC) reduced germination from 94% for fresh seed to 31%. The small epidermal cells of the leaves and the large multicellular hairs (Ormrod and Renney, 1968) may also assist in its drought tolerance. Influence of selfing and maternal effects on life-cycle traits and dispersal ability in the herb Hypochaeris radicata (Asteraceae). (2012) described its use in traditional medical practice for its anticancer, anti-inflammatory, anti-diuretic and hepatoprotective activity, and also in treating kidney problems. ITIS (2013) prefered the form Hypochaeris radicata. https://npgsweb.ars-grin.gov/gringlobal/taxon/taxonomysearch.aspx, USDA-NRCS, 2013. Stapledon (1948) suggested sowing H. radicata in grazed grasslands along with a non-aggressive grass.

The ripe fruit is orange-brown in colour, 4-5 mm long with about 15 longitudinal ridges and a beak-like apex with a pappus of an outer ring of short simple hairs and an inner ring of feathery ones. H. radicata is a herbaceous perennial originally native to Morocco. In the UK, H. radicata is primarily a plant of regularly cut or grazed neutral grasslands, of grassland on sandy soils, and of man-made habitats with bare soil. (2008) proposed that there were possibly two or more independent colonisations of the UK. Herbaceous perennial growing from hard, thickened, overwintering base (caudex); fibrous-rooted, but often with several enlarged roots, appearing tap-rooted; leaves in a basal rosette, hairv (hispid), oblanceolate, toothed or pinnatifid, 3-25 cm long and 0.5-7 cm wide; stems (stalks) 15-60 cm tall , branched above, or in small plants simple, sparsely and minutely bracteate, or naked, often spreading-hispid below, possessing a ‘milky’ juice; leafless, with small scale-like bracts only; flower heads (capitula) yellow, 20-30 (-40) mm wide, usually several, terminating the branches and rather showy; florets ligulate, monoclinous and bisexual, the ligules surpassing the involucre and about four times as long as wide; involucre l0-15 mm high at anthesis, up to about 25 mm in fruit, its bracts imbricate, glabrous or hispid; fruit an achene, orange or brown, body of the achene mostly 4-7 mm long, from a little longer to more often much shorter than the slender beak, the prominent nerves and the lower part of the beak muricate; pappus plumose with two rows of hairs, shorter outer hairs commonly merely barbellate. Relative weight of leaves and roots decreased and relative weight of floral organs increased with decreasing stand defoliation. Flexible life history responses to flower and rosette bud removal in three perennial herbs. (2003) experimented with different levels of copper added to soil and measured its effects on H. radicata and other species found in European vineyards, where high concentrations of copper are found in the soil surface due to the repeated use of copper-based fungicides for protection against vine downy mildew (Plasmopara viticola).

Struik (1967) studied the size and growth of H. radicata in mown and unmown lawns and in heavily and lightly grazed pastures in New Zealand. Experimental methods. This spread was probably helped by an important change in ecological tolerance, allowing H. radicata, originally suited to humid Mediterranean woodlands, to invade more open temperate grasslands. (1953) analysed the chemical components of H. radicata in New Zealand: protein 10-15%, fibre 10-20%, calcium 1-2%, phosphorus 0.15-0.5% and copper 5-10 ppm, on a dry matter basis. A comparative study of germination characteristics in a local flora. Plants for a Future. The mature leaves grow to 15 to 20cm long. In New Zealand it is ‘abundant in waste places, pasture and modified tussock grassland through both islands and extending from sea-level to the upper level of vegetation on the mountains’ (Healy, 1992).

Chemical composition of some tussock grassland pastures. Fone AL, 1989. From a nutrition perspective, several supplements have been tried: thiamine, taurine, and antioxidants (vitamins E and C), for example. Compendium record. It is in flower from June to September, and the seeds ripen from July to September. Turkington and Aarssen (1983) presented a large table of species associated with H. radicata in the Sheffield area in England, UK, and also listed many communities in which it occurs. http://www.itis.gov/, Jamuna S; Paulsamy S; Karthika K, 2012.

Indust. The reproductive capacity of plants. No. of Agriculture). Hughes JG, 1975. Ridley (1930, cited in Aarssen, 1981) reported that birds are known to disperse the fruit by attachment to their feet and plumage, and ants have been observed carrying seeds of H. radicata. In Nilgiris (Tamil Nadu, India), traditional healers prescribed H. radicata for wound healing and skin diseases caused by pathogens. Cat’s ear (Hypochaeris radicata) is often confused with a dandelion — so much so that it is referred to as “false dandelion.” This look-a-like plant has similar structure, grows in a similar habitat, drives homeowners nuts when it pops up in well-manicured lawns, spits a white milky sap when snapped and has a similar nutritional profile to the dandelion.

It is widespread and abundant in coastal terrace prairie and coastal bluff scrub, often one of the more dominant species. Database. In addition, when flowering was prevented, plants switched their resources to greater vegetative reproduction and they generated more new rosettes. Please click here for more information. See our Written Findings for more information about common catsear (Hypochaeris radicata). Davis, California, USA: Weed Research and Information Center, University of California, 544 pp. Seeds may have also been taken by European migrants to North and South America, Asia, Australia and New Zealand deliberately for medicinal or food purposes. Hypochaeris radicata is a perennial herb, commonly called as ‘hairy cat’s-ear’. It grows almost everywhere and in pretty much any condition. Weeds of Australia, 2013. Global Invasive Species Database (GISD). Weeds of Australia, Biosecurity Queensland Edition. The PLANTS Database. Artichoke Cynara … In New Zealand, Healy (1992) described the distribution of the introduced H. radicata as ‘one of, if not the most widely distributed introduced weeds on a geographical and altitudinal basis.’ It is considered one of the most invasive alien plants on the island of La Reunion (ISSG, 2013). Salisbury EJ, 1942. California Invasive Plants Council. Tussock Grasslands and Mountain Lands Institute Review, No.31:20-30. It does not however tolerate poorly drained soils.

More information about modern web browsers can be found at http://browsehappy.com/. Ho (1964, cited in Aarssen, 1981) said that freshly harvested seeds did not need a period of dormancy before germination, that light is needed for germination and that seeds lost viability rapidly in dry storage. Schoenfelder AC; Bishop JG; Martinson HM; Fagan WF, 2010. Screening of in vitro antioxidant activity of methanolic leaf and root extracts of Hypochaeris radicata L. (Asteraceae). Related Links. Ho LS, 1964. Although widespread in the USA, H. radicata seems to have stabilized there and, according to DiTomaso et al. Related Species and Look-Alikes: Chicory (Cichorium intybus) and cat’s-ear (Hypochaeris radicata) are sometimes mistaken for dandelion. (2012) also investigated the antibiotic properties of roots and leaves and found that ‘the antibacterial activity of the methanolic extracts of both parts was comparable to that of the standard drug, ampicillin.’. Although Salisbury (1964) claimed that ‘the flower heads close at night but open in daylight even when it is dull and cloudy’, Percival (1950) said that sunlight is necessary to stimulate the flowers to open in the morning, and that the flowers do not open in rain or if rain and sun alternate for about half an hour each. Salisbury E, 1964. ITIS (2013) prefered the form Hypochaeris radicata. Cabrera AL, 1971. Recorded diploid counts for both British and Canadian plants are 2n=8 (Aarssen, 1981; Turkington and Aarssen, 1983). The goal of this web-exclusive feature is to zero in on specific areas of hoof nutrition and avoid broad-based articles that simply look at the overall equine feeding situation. In essence, in the rosette stage H. radicata has rounded leaf lobes, hairs on the leaf margins, a thick, rough leaf surface, and simple leaf hairs. Weed Control in Natural Areas in the Western United States. Tolerates, or benefits from, cultivation, browsing pressure, mutilation, fire etc, Benefits from human association (i.e. by Burkart, A.].
