  • Barcoding the Asteraceae of Tennessee, Tribe Senecioneae
    Schilling, E.E. and A. Floden. 2014. Barcoding the Asteraceae of Tennessee, tribe Senecioneae. Phytoneuron 2014-34: 1–5. Published 14 March 2014. ISSN 2153 733X BARCODING THE ASTERACEAE OF TENNESSEE, TRIBE SENECIONEAE EDWARD E. SCHILLING AND AARON FLODEN Herbarium TENN Department of Ecology & Evolutionary Biology University of Tennessee Knoxville, Tennessee 37996 [email protected]; [email protected] ABSTRACT Results from barcoding studies of tribe Senecioneae for the Tennessee flora using data from the nuclear ribosomal ITS marker region are presented and include first complete reports of this marker for 3 of the 15 species of these tribes that occur in the state. Sequence data from the ITS region separated all Tennessee species of Arnoglossum , Erechtites , Hasteola , and Rugelia (all of which are native) from one another and from other, non-Tennessee congeners. In contrast, many of the species of Packera , both from the state and from other parts of the southeastern USA, had basically identical ITS sequences. The contrast in the distinctiveness of Arnoglossum species compared to those of Packera suggests the two genera have had different histories of introduction and diversification in southeastern North America. Tribe Senecioneae is one of the largest in Asteraceae and with a worldwide distribution has had the opportunity to diversify in many different regions. The boundaries and circumscription of the tribe have, however, changed over the past few decades, and its generic level circumscription is still being settled (Nordenstam et al. 2009; Pelser et al. 2007, 2010). Notable is the problem of the circumscription of the huge Senecio (ca. 1000 species), but changes have also affected other genera from the southeastern USA, most notably the recognition of Arnoglossum and Hasteola as distinct from Cacalia (Anderson 1974).

Who knew then that we were only months away from a global pandemic that would disrupt everything we thought of as normal, and that the ensuing shutdown would cause such increased interest in gardening? This past year has been a rollercoaster ride for all of us in the nursery and landscape trades. The demand for plants so exceeded the supply that it caused major plant availability shortages, and then the freeze in Texas further exacerbated this situation. To ensure that our customers came first, we did not sell any plants out-of-state, and we continue to work hard to refill the empty spaces left in our field. In the chaos of the situation, we also decided not to produce a 2020 catalog, and this current catalog is coming out so late that we intend it to be a two-year edition. Some items listed may not be available until early next year, so we encourage customers to look to our website Primelist which is updated weekly to view our current availability. As in the past, we continue to grow the many tried-and-true favorite plants that have proven themselves in our warming mediterranean climate. We have also added 245 exciting new plants that are listed in the back of this catalog. With sincere appreciation to all our customers, it is our hope that 2021 and 2022 will be excellent years for horticulture!

It is found to be identical with L. dentata subsp. sutchuenensis and is thus synonymized herein. Key words: Compositae, Sichuan, synonymy, taxonomy Introduction Ligularia emeiensis Kitamura (1991: 148) was described on the basis of three gatherings, J. Murata 11571 (KYO; Fig. 1A), W.P. Fang 15048 (KUN, KYO, PE, SZ; Fig. 1B, C) and C.L. Chow 6943 (KYO, SZ; Fig. 1D), all from Emei Shan, Sichuan, China, with the first designated as the holotype. In the protologue, the author gave only a full Latin description for his new species, not noting its affinity. Since its publication L. emeiensis has been totally overlooked by later authors. Even in their account of the genus Ligularia Cassini (1816: 198) for the Flora of China, Liu & Illarionova (2011) did not treat it.

Senecio vulgaris L. is a particularly noxious weed in agricultural and horticultural crops due to its content of toxic pyrrolizidine alkaloids (PAs). Since some of these compounds are carcinogenic, the distribution of this plant should be monitored. The amount of PAs in S. vulgaris is affected by various factors. Therefore, we investigated the occurrence of PAs depending on the developmental stage and season. A systematic study using field-plot experiments (four seasons, five developmental stages of the plants: S1 to S5) was performed and the PA concentration was determined via LC-MS/MS analysis.

  • Supplement to the Systematics of the Heliantheae (Compositae)
    Boletín de la Sociedad Argentina de Botánica Volumen XIX, N? 1-2 (Julio 1980), págs. 25-32 SUPPLEMENT TO THE SYSTEMATICS OF THE HELIANTHEAE (COMPOSITAE) Por TOD F. STUESSY2 Since the completion of a revised subtribal classification of the tribe Heliantheae (Stuessy, in press) for the Reading Symposium on the Compositae in July of 1975, a number of new papers have been published on the systematics of the tribe. This new informa¬ tions falls into four general categories: (1) speculations on relation¬ ships among the newly recognized subtribes; (2) addition of a new subtribe; (3) additions of new genera; and (4) new generic transfers. The purpose of this paper is to review these new developments and comment on their significance for the systematics of the Heliantheae. RELATIONSHIPS AMONG THE NEWLY RECOGNIZED SUBTRIBES An important new overview of relationships among the sub¬ tribes of the Heliantheae has been provided by Baagoe (1977) by use of ligule microcharacters. This contribution is especially valuable, because the manuscript on the Heliantheae for the Reading Sympo¬ sium (Stuessy, in press) was available to Dr. Baagoe during her study, and she was able to relate the new data to the subtribal clas¬ sification of the tribe. Many specific comments on relationships are contained in her paper, but this review will focus only on some of the broader implications. Before these are examined, however, a few cautions need to be raised. 1 It is a pleasure to dedicate this paper to Dr. Angel L. Cabrera, one of the outstanding synantherologists of the world, and the unqualified authority on South American Compositae.

PhytoKeys 149: 89–98. https://doi.org/10.3897/phytokeys.149.52297 Abstract Senecio festucoides is described from northern Chile. The new species is morphologically similar to the discoid caespitose Andean species and belongs to the subgroup displaying yellow corollas and yellowish anthers and style branches. It is characterized by a weak, not self-supporting stem, narrowly linear leaves, long pedunculate capitula with (17–)21 involucral bracts, and minutely papillose achenes. Among other characters, the color of the corollas, anthers, and style branches and the number of involucral bracts dif- ferentiate it from S. scorzonerifolius, which is the morphologically closest species. The new species thrives in the desertic Puna ecoregion and grows amongst tufts of Festuca chrysophylla (Poaceae). Detailed pictures of living plants are provided, as well as a distribution map and a dichotomous key to the discoid caespitose Senecio species from northern Chile.
