  • 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.

The following pages were originally designed for my own use alone, but the consideration that there must be many collectors and owners of coins who would gladly give more attention to this very interesting but somewhat involved branch of numismatics—were they not deterred by having no easily accessible information on the subject—has in- duced me to offer them to the public. My aim has been to provide a description of every coin issued by the Scottish Mint, with particulars as to weight, fineness, rarity, mint-marks, &c., gathered from the best authorities, whom many collectors would probably not have the opportunity of consulting, except in our large public libraries ; at the same time I trust that the information thus brought together may prove sufficient to refresh the memory of the practised numismatist on points of detail.

  • 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.

  • THE EARLS of DALHOUSIE WHO WERE ALSO MEMBERS of the MOST ANCIENT and MOST NOBLE ORDER of the THISTLE (From Dennis Hurt and Wayne R
    THE EARLS OF DALHOUSIE WHO WERE ALSO MEMBERS OF THE MOST ANCIENT AND MOST NOBLE ORDER OF THE THISTLE (from Dennis Hurt and Wayne R. Premo) In 2017, Dennis Hurt (Clan member #636) and his Lady Susan, who are avid participants in the Colorado Scottish / Celtic Festivals each year, traveled to the United Kingdom as many of us have over these past decades. While visiting Scotland and particularly Edinburgh, they decided to “take in” St. Giles High Kirk (Kirk meaning Church; or High Kirk meaning Cathedral, in this case) which is located on High Street (The Royal Mile) in Old Town Edinburgh. St. Giles Cathedral or High Kirk of Edinburgh is THE principal place of worship of the Church of Scotland in Edinburgh (Wikipedia online). St. Giles High Kirk today – The Royal Mile – Edinburgh While online websites have a great deal of information with photos about St. Giles High Kirk, what is important to this narrative is the fact that the Thistle Chapel, a section therein, was dedicated in 1911 to the Most AnCient anD Most Noble OrDer oF the Thistle, SCotlanD’s Foremost OrDer oF Chivalry. Again from Wikipedia: “The Most AnCient anD Most Noble OrDer oF the Thistle is an order of chivalry associated with Scotland. The current version of the Order was founded in 1687 by King James VII 1 of ScotlanD (James II of England and Ireland) who asserted that he was reviving an earlier Order. The Order consists of the Sovereign and sixteen Knights and Ladies, as well as certain "extra" knights (members of the British Royal Family and foreign monarchs).

    G C A T T A C G G C A T genes Article Genetic Dissection of Apomixis in Dandelions Identifies a Dominant Parthenogenesis Locus and Highlights the Complexity of Autonomous Endosperm Formation Peter J. 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.
