  • List of Vascular Plants Endemic to Britain, Ireland and the Channel Islands 2020
    British & Irish Botany 2(3): 169-189, 2020 List of vascular plants endemic to Britain, Ireland and the Channel Islands 2020 Timothy C.G. Rich Cardiff, U.K. Corresponding author: Tim Rich: [email protected] This pdf constitutes the Version of Record published on 31st August 2020 Abstract A list of 804 plants endemic to Britain, Ireland and the Channel Islands is broken down by country. There are 659 taxa endemic to Britain, 20 to Ireland and three to the Channel Islands. There are 25 endemic sexual species and 26 sexual subspecies, the remainder are mostly critical apomictic taxa. Fifteen endemics (2%) are certainly or probably extinct in the wild. Keywords: England; Northern Ireland; Republic of Ireland; Scotland; Wales. Introduction This note provides a list of vascular plants endemic to Britain, Ireland and the Channel Islands, updating the lists in Rich et al. (1999), Dines (2008), Stroh et al. (2014) and Wyse Jackson et al. (2016). The list includes endemics of subspecific rank or above, but excludes infraspecific taxa of lower rank and hybrids (for the latter, see Stace et al., 2015). There are, of course, different taxonomic views on some of the taxa included. Nomenclature, taxonomic rank and endemic status follows Stace (2019), except for Hieracium (Sell & Murrell, 2006; McCosh & Rich, 2018), Ranunculus auricomus group (A. C. Leslie in Sell & Murrell, 2018), Rubus (Edees & Newton, 1988; Newton & Randall, 2004; Kurtto & Weber, 2009; Kurtto et al. 2010, and recent papers), Taraxacum (Dudman & Richards, 1997; Kirschner & Štepànek, 1998 and recent papers) and Ulmus (Sell & Murrell, 2018). Ulmus is included with some reservations, as many taxa are largely vegetative clones which may occasionally reproduce sexually and hence may not merit species status (cf.

The new diagnostic features of the genus Pietrosia justify its taxonomic recognition as separate from Andryala; those are the achene size (between 2.5 and 4.3 mm long), the deciduous pappus, the single-rimmed achene apex, the elongate exocarpic cells, the complete ring of mesocarpic sclerenchyma (up to 11-layered), and the number and localization of the vascular bundles (5 bundles, in the small ribs). Furthermore, our data may also serve to reconsider the species ecology and conservation strategies. Key words: carpology, Compositae, conservation, Eastern Carpathians, endangered species, endemism, Romania, sexual propagation Introduction Pietrosia laevitomentosa Nyár. in Sennikov (1999: 78) is still an enigmatic species despite being the subject of active scientific interest after its discovery fifty years ago. It was the only species assigned to the genus Andryala found so far north, as all the other species occur in the Mediterranean Region and Macaronesia (Lucas & Synge 1978). According to published reports, the plant has a very restricted distribution in an area of about 150 square meters on rocky slopes of the Pietrosul Bistriţei Mountain (Eastern Carpathians, Romania).

Cernua (Asteraceae) from Romania ZBIGNIEW SZELĄG Zbigniew Szeląg, Pedagogical University of Cracow, Department of Botany, Podchorążych 2, 30-084 Kraków, Poland, [email protected] Abstract Hieracium joannei, a new, apomictic species in H. sect. Cernua is described from the Şureanu Mountains, Southern Car- pathians, Romania, and illustrated with photos of the holotype and living plants in the locus classicus. Hieracium zanogae (= H. tubulare), previously considered to be endemic to the Retezat Mountains, has been found in the Parâng Mountains. This is the easternmost occurrence of the species, disjoined ca 50 km from the nearest localities in the Retezat Mountains. A key for the species of H. sect. Cernua in Romania is provided. Key words: Carpathians, Compositae, Hieracium, taxonomy Introduction Hieracium sect. Cernua Uechtritz (1875: 215) comprises two diploid, sexual species, H. sparsum Frivaldszky (1836: 436) and H. cernuum Frivaldszky (1840: 204) (Ilnicki & Szeląg 2011, Szeląg & Ilnicki 2011, Szeląg et al. 2007), and ca 40 agamospermous species of hybrid origin between both diploids and taxa belonging to other sections (Zahn 1938). In Romania H. sect. Cernua is represented by 15 endemic species (Szeląg 2006). The present occurrence of H. sect. Cernua in Romania is what has been left of the original range of H. sparsum and H. cernuum (both currently limited to the Balkan Peninsula), and is a relict.

  • Orange Hawkweed Pilosella Aurantiacum (Hieracium)
    Orange hawkweed Other common names: USDA symbol: HIAU Pilosella aurantiacum (Hieracium) Devil’s paintbrush ODA rating: A and T Introduction: Orange hawkweed is native to Europe. One of the more attractive hawkweeds, people have been very instrumental in distributing this plant throughout the country. Orange hawkweed is found from western Washington to Wyoming and is known to occur in eastern states. It is very aggressive, rapidly invading any habitat where it is introduced. Oregon’s populations are still limited but increasing in urban areas. Distribution in Oregon: Distribution is limited but expanding. The well-established population in Clackamas County is our oldest site with newer populations reported throughout central and south central Oregon. Description: Orange hawkweed is an aggressive perennial hawkweed sporting attractive, showy orange flowers. The bright orange flowers attract gardeners who are unaware of its aggressive nature. It rapidly spreads through lawns, flowerbeds and meadows through abundant seed production and aboveground runners (stolons) that root at the tips creating dense populations. The flower stalks grow up to 12+ inches tall and contain a milky sap. The vibrant orange-red flowers are clustered at the top of leafless stems. The stems are entirely covered by stiff, black, glandular hairs. Leaves are hairy, lance shaped, up to five inches long, and exclusively basal. Impacts: Once established, hawkweed quickly develops into a monoculture that continues to expand until it covers the site. A dense mat of hawkweed plants has the potential to eliminate or restrict other vegetation, even lawns. Its unpalatable vegetation displaces native vegetation posing a serious threat to native plant communities while also invading pastures and roadsides.

Van Dijk 1,*, Rik Op den Camp 1 and Stephen E. Schauer 2 1 Keygene N.V., Agro Business Park 90, 6708 PW Wageningen, The Netherlands; [email protected] 2 Keygene Inc., Rockville, MD 20850, USA; [email protected] * Correspondence: [email protected]; Tel.: +31-317-466-866 Received: 20 July 2020; Accepted: 18 August 2020; Published: 20 August 2020 Abstract: Apomixis in the common dandelion (Taraxacum officinale) consists of three developmental components: diplospory (apomeiosis), parthenogenesis, and autonomous endosperm development. The genetic basis of diplospory, which is inherited as a single dominant factor, has been previously elucidated. To uncover the genetic basis of the remaining components, a cross between a diploid sexual seed parent and a triploid apomictic pollen donor was made. The resulting 95 triploid progeny plants were genotyped with co-dominant simple-sequence repeat (SSR) markers and phenotyped for apomixis as a whole and for the individual apomixis components using Nomarski Differential Interference Contrast (DIC) microscopy of cleared ovules and seed flow cytometry. From this, a new SSR marker allele was discovered that was closely linked to parthenogenesis and unlinked to diplospory. The segregation of apomixis as a whole does not differ significantly from a three-locus model, with diplospory and parthenogenesis segregating as unlinked dominant loci. Autonomous endosperm is regularly present without parthenogenesis, suggesting that the parthenogenesis locus does not also control endosperm formation.

    FSC Nettlecombe Court Nature Review 2014 Compiled by: Sam Tuddenham Nettlecombe Court- Nature Review 2014 Introduction The purpose of this report is to review and share the number of different species that are present in the grounds of Nettlecombe Court. A significant proportion of this data has been generated by FSC course tutors and course attendees studying at Nettlecombe court on a variety of courses. Some of the data has been collected for the primary purpose of species monitoring for nationwide conservation charities e.g. The Big Butterfly Count and Bee Walk Survey Scheme. Other species have just been noted by members or staff when out in the grounds. These records are as accurate as possible however we accept that there may be species missing. Nettlecombe Court Nettlecombe Court Field Centre of the Field Studies Council sits just inside the eastern border of Exmoor national park, North-West of Taunton (Map 1). The house grid reference is 51o07’52.23”N, 32o05’8.65”W and this report only documents wildlife within the grounds of the house (see Map 2). The estate is around 60 hectares and there is a large variety of environment types: Dry semi- improved neutral grassland, bare ground, woodland (large, small, man –made and natural), bracken dominated hills, ornamental shrubs (lawns/ domestic gardens) and streams. These will all provide different habitats, enabling the rich diversity of wildlife found at Nettlecombe Court. Nettlecombe court has possessed a meteorological station for a number of years and so a summary of “MET” data has been included in this report.

  • Mouse Ear Hawkweed- Hieracium Pilosella Leafy Spurge- Euphorbia
    Mouse Ear Hawkweed- Hieracium pilosella General Description: The plant has a basal rosette of narrow, pointed, hairy leaves with a single, upright yellow flower. Its seeds are purplish black and columnar. Plants spread primarily by stolons that grow along the ground, root and form other plants. It flowers in spring and fall in some climates. Why it is Invasive: Its creeping growth fills in the gaps between other plants forming mats of rosettes which prevent other plants from establishing seedlings. Chemical Control: Some sources recommend early season glyphosate treatment, however our observations indicate that 2% Aquaneat (ai glyphosate) is ineffective (Nathan Johnson pers obs). Milestone VM (ai aminopyralid) at 0.5% gives consistent, effective control. This plant often sets seed if flowers are present when sprayed. Detection: Individuals and small mats are difficult to detect unless they are flowering. Large mats are easy to detect year round. Surveys of known infestations may turn up plants any time of year. Leafy Spurge- Euphorbia esula General Description: Leafy spurge is an aggressive, deep-rooted perennial, growing to a height of 2-3 feet. Stems arise from a woody root crown just below the soil surface. The stems are tightly clustered and bare narrow leaves that are 1-4 inches long. Leafy spurge produces clusters of yellowish-green bracts, which surround the true flowers. Leafy spurge reproduces by vegetative growth from spreading roots and by the production of large quantities of seeds. Why it is Invasive: Leafy spurge can crowd out native plants and high infestations can produce large amounts of seeds which can dominate a seed bank and pose continued problems regarding efforts to re- vegetate a site or restore native vegetation.

  • Hawkweeds: State Prohibited Weed (DPI Vic)
    June 2003 Hawkweeds: State Prohibited Weed LC0376 Keith Turnbull Research Institute, Frankston ISSN 1329-833X This Landcare Note describes Hieracium spp., hawkweeds, as State Prohibited Weeds in Victoria. Common name Hawkweeds Scientific name Hieracium spp. Family Asteraceae (daisies) Status Hieracium species are proclaimed as a State Prohibited Weed in Victoria. This means that Hieracium spp. are to be eradicated if possible from the State. Hieracium species are also proclaimed weeds in New South Wales, Western Australia and Tasmania and have been classified as prohibited imports by the Australian Quarantine and Inspection Service. There are between 700 and 1000 world species of Hieracium, mostly native to the Northern Hemisphere in temperate and montane areas, but with some species in South America and southern Africa. No species are native to Australia. Orange hawkweed Hieracium aurantiacum, native to Europe, is the only species known to have become naturalised in Victoria. Small infestations are known from Falls Creek and Mt Hotham. Other hawkweed species have been available from nurseries and markets and are likely to be present in gardens. Description Herbs with milky sap, often hairy, with a basal rosette of leaves. The group is divided into two subgenera: Pilosella, which contains perennial, stoloniferous, often mat-forming species that reproduce sexually, and Hieracium, which contains annual, non-stoloniferous species, that reproduce asexually by seed and produce little pollen. Commonly each species is highly variable and contains several subspecies. Hybrids occur frequently. Stems – erect, the creeping stolons root readily at the nodes, like a strawberry plant. Leaves – in a basal rosette or alternate on the stems, entire or toothed, rarely lobed, often hairy.
